Avianca Flight 052 was a regularly scheduled flight from Bogotá, Colombia, to New York City, United States, via Medellín, Colombia, that crashed on January 25, 1990, at 21:34 (UTC−05:00). The Boeing 707 flying this route ran out of fuel after a failed attempt to land at John F. Kennedy International Airport (JFK), causing the aircraft to crash onto a hillside in the small village of Cove Neck, New York, on the north shore of Long Island. Eight of the nine crew members and 65 of the 149 passengers on board were killed. The National Transportation Safety Board (NTSB) determined that the crash occurred due to the flight crew failing to properly declare a fuel emergency, failure to use an airline operational control dispatch system, inadequate traffic flow management by the Federal Aviation Administration (FAA), and the lack of standardized understandable terminology for pilots and controllers for minimum and emergency fuel states.

The flight left Medellín with more than enough fuel for the journey and progressed toward JFK normally. While en route, the flight was placed in three holding patterns. Due to the air traffic controllers giving ultimately untrue delay estimations the flight became critically low on fuel. This dire situation was not recognized as an emergency by the controllers because of the failure of the pilots to use the word "emergency". The flight attempted to make a landing at JFK, but bad weather, coupled with poor communication and inadequate management of the aircraft, forced it to abort and attempt a go-around. The flight ran out of fuel before it was able to make a second landing attempt. The airplane crashed about Шаблон:Convert from JFK.

Hundreds of emergency personnel responded to the crash site and helped save victims. Many of those who survived were severely injured and required months or years to physically recover. NTSB investigators looked at various factors that contributed to the crash. The failures of the flight crew were cited as the probable cause of the crash, but the weather, air traffic controller performances, and FAA traffic management were also cited as contributing to the events that led to the accident. This conclusion was controversial, with disagreement between investigators, passengers, and Avianca as to who was ultimately responsible. Eventually, the U.S. government joined with Avianca and settled to pay for the damages to the victims and their families. The crash has been portrayed in a variety of media.

Background

The Avianca Flight 052 aircraft was a Boeing 707-321B (registration number HK-2016).[1]Шаблон:Rp The aircraft was manufactured in June 1967, and was purchased by Avianca from Pan Am in 1977. By the time of the crash, the aircraft was 22 years old and had over 61,000 flight hours. The 707 was equipped with four Pratt & Whitney JT3D-3B engines modified with a hush kit to reduce noise pollution.[1]Шаблон:Rp Avianca personnel reported that they factored in a 5% fuel overburn into the performance calculations due to the hush kit, along with an additional 5% overburn due to the age of the aircraft.[1]Шаблон:Rp Additionally, maintenance crews had noted recurring issues with the aircraft's autopilot, including the altitude hold function. These same issues were reported on the aircraft's penultimate flight, but maintenance was unable to fix the autopilot, and it was disabled as a result.[1]Шаблон:Rp

The flight was staffed by a crew of nine, including six flight attendants and three flight crewmen.[1]Шаблон:Rp The flight crew in the cockpit consisted of 51-year-old Captain Laureano Caviedes Hoyos, 28-year-old first officer Mauricio Klotz and 45-year-old flight engineer Matias Moyano.[1]Шаблон:RpШаблон:Efn[2] At the time of the crash, Captain Caviedes had been employed with Avianca for over 27 years and had logged over 16,000 hours of flight time, including over 1,500 in the 707.Шаблон:Efn[1]Шаблон:Rp Caviedes had 478 hours of night flying experience in the 707 (and 2,435 hours of night flying experience in total) and had no record of any prior accidents. Co-pilot Klotz had been employed with Avianca for three years and had 1,837 hours of flight time, with 408 hours at night. Klotz had transitioned to the 707 the previous October and had logged 64 flight hours in the airframe, including 13 at night.[1]Шаблон:Rp Flight engineer Moyano had been employed with Avianca for over 23 years and had over 10,000 hours of flight time, including over 3,000 hours in the 707 and over 1,000 hours of night flying in the same airframe (and 2,986 hours of night flying regardless of airframe).[1]Шаблон:Rp

All three flight crew members had previous experience in landing at JFK.[1]

Flight

Avianca Flight 052 was a regularly scheduled international passenger flight from El Dorado International Airport in Bogotá, Colombia, to JFK in Queens, New York, with an intermediate stop at José María Córdova International Airport near Medellín, Colombia.[1]Шаблон:Rp

Flight 052 departed Bogotá at 13:10 Eastern Standard Time, five minutes ahead of schedule, on January 25, 1990.[1]Шаблон:RpШаблон:Efn The flight landed at Medellín at 14:04 and prepared to fly the leg to JFK. At Medellín, the aircraft landed with Шаблон:Convert of fuel. The flight plan filed for the journey to JFK called for Шаблон:Convert of fuel required for the trip to JFK, Шаблон:Convert for reserve fuel, Шаблон:Convert for alternate fuel, Шаблон:Convert for holding fuel, and Шаблон:Convert of taxi fuel totaling Шаблон:Convert minimum of block fuel.[1]Шаблон:RpШаблон:Efn The dispatcher at Medellín ordered a total fuel load of Шаблон:Convert, including Шаблон:Convert of "top off" fuel to raise the aircraft weight to the maximum allowable for the planned departure runway. At Medellín, the captain and dispatcher decided to use another runway and requested an additional Шаблон:Convert of fuel.[1]Шаблон:RpШаблон:Efn

The flight departed Medellín at 15:08, bound for JFK.[1]Шаблон:Rp The flight first entered U.S. airspace of Miami Air Route Traffic Control Center at 17:28, flying at Шаблон:Convert, and proceeded northward, climbing to Шаблон:Convert.Шаблон:Efn The flight was cleared to fly Atlantic route 7 to the DIXON navigational aidШаблон:Efn and jet airway 174 to Norfolk, Virginia. Flight 052 entered its first holding pattern over Norfolk at 19:04 and remained circling until 19:23. From there, Flight 052 continued on to the BOTON intersection near Atlantic City, New Jersey, where it was placed in a second holding pattern from 19:43 to 20:12.Шаблон:Efn The flight proceeded to the CAMRN intersection where it entered its third holding pattern from 20:18 to 20:47.Шаблон:Efn[1]Шаблон:Rp Flight 052 entered the CAMRN holding pattern at Шаблон:Convert, having been cleared to descend prior to arrival at the intersection, and the flight descended further to Шаблон:Convert while in the CAMRN holding pattern. At 20:44:09, while still holding at CAMRN, the New York Air Route Traffic Control Center (ZNY) advised Flight 052 that there was an "indefinite hold" and to continue holding at CAMRN.[1]Шаблон:Rp At 20:44:43, the ZNY controller told the flight to "expect further clearance" at 21:05.[1]Шаблон:RpШаблон:Efn The flight had previously been given two delay estimates that had passed.[1]Шаблон:Rp

At that point, First Officer Klotz radioed the controller, saying, "ah well I think we need priority we're passing [unintelligible]."[1]Шаблон:Rp The controller inquired as to how long the flight could hold, as well as what their alternative airport was. Klotz replied at 20:46:03 that they could hold for five more minutes.[1]Шаблон:Rp The controller once again inquired as to their alternative airport and Klotz replied at 20:46:24, "It was Boston, but we can't do it now we, we, don't, we run out of fuel now."[1]Шаблон:Rp A handoff controller listening in on the conversation called the New York Terminal Radar Approach Control (NY TRACON) at 20:46:24 and advised the TRACON controller that Avianca Flight 052 could only hold for five more minutes.[1]Шаблон:Rp The handoff controller asked whether NY TRACON could take the flight or whether to send Avianca to its alternative airport.[1]Шаблон:Rp The NY TRACON controller replied, "Slow him to one eight zero knots and I'll take him."[1]Шаблон:RpШаблон:Efn The handoff controller later testified that he had not heard Flight 052 say that they could no longer reach their alternative airport. At 20:46:47, the NY ARTCC radar controller cleared the flight to proceed to JFK at Шаблон:Convert and to slow to Шаблон:Convert. Flight 052 departed the CAMRN holding pattern at 20:47.[1]Шаблон:Rp

Landing attempt

Final flight path and significant events leading up to the crash

At 20:47:27, the NY TRACON feeder controller told the flight crew to "expect an ILS two two left"Шаблон:Efn "altimeter two niner six niner proceed direct Deer Park."Шаблон:Efn At 20:54:40, the feeder controller directed Flight 052 to make a 360° turn. At 20:56:16, the controller gave the flight a wind shear advisory of an "increase of 10 knots at 1500 feet and then an increase of 10 knots at 500 feet."[1]Шаблон:Rp The flight crew acknowledged the advisory. At 21:00, JFK was experiencing light drizzle and fog with Шаблон:Frac mile visibility, an indefinite ceiling with Шаблон:Convert obscured, and a wind of Шаблон:Convert at 190°.[1]Шаблон:Rp

At 21:03:07, Flight 052 contacted the NY TRACON final controller, who cleared them to descend progressively to Шаблон:Convert.[1]Шаблон:Rp At 21:03:46, the flight crew discussed the go-around procedures. At 21:09:29, flight engineer Moyano stated that the controllers "already know that we are in [a] bad condition."[1]Шаблон:Rp The captain said, "No they are descending us," and the second officer added, "They are giving us priority."[1]Шаблон:Rp At 21:11:07, the NY TRACON final vector controller informed the flight that they were 15 miles from the outer marker and instructed them to maintain an altitude of Шаблон:Convert "until established on the localizer."[1]Шаблон:Rp The flight crew began preparing for an instrument landing approach, extending flaps and discussing the appropriate airspeed. The final controller instructed the flight crew to contact the JFK tower controllers and signed off. Klotz acknowledged the transmission.[1]Шаблон:Rp

At 21:15:19, Klotz contacted the tower controllers and informed that Flight 052 was "established two two left."[1]Шаблон:Rp One minute later, the captain asked if he should lower the landing gear, but the first officer replied, "No I think it's too early now."[1]Шаблон:Rp At 21:17:30, JFK tower asked Flight 052 to increase their airspeed by 10 knots to Шаблон:Convert. At 21:18:11, the flight was Шаблон:Convert from the outer marker. Twenty-one seconds later, the first officer remarked "glideslope alive."[1]Шаблон:Rp At 21:19:09, the captain requested the landing gear be deployed.[1]Шаблон:Rp Almost a minute later, the JFK tower cleared the flight to land on runway 22L. The captain asked the first officer to confirm that the flight was cleared to land. At 21:20:28, the first officer began informing the captain that the aircraft was below the glideslope. At 21:22:07, Flight 052 descended to Шаблон:Convert. The aircraft began descending beyond the angle of the glideslope, then began climbing above it, followed by a steeper descent. At 21:22:57, the first officer commented, "This is the wind shear."[1]Шаблон:Rp The first officer warned the captain about the sink rate and noted an altitude of Шаблон:Convert at 21:23:10. As he warned the captain, the ground proximity warning system (GPWS) began 11 "whoop, whoop, pull up" audible warnings. At 21:23:13, the captain called for lights, followed by questions as to where the runway was a few seconds later. The GPWS began four "glideslope" audible warnings a few seconds later, alerting the flight crew that the aircraft was below the glideslope. In response to the captain's inquiries, the first officer replied that he did not see the runway.[1]Шаблон:Rp At 21:23:23, the flight began climbing again, having come within Шаблон:Convert of crashing 2 miles short of the runway. The landing gear was raised, and the first officer announced that the flight was executing a missed approach.[1]Шаблон:Rp

The JFK tower controller asked the flight to climb to Шаблон:Convert and make a left turn. At 21:24:06, the captain asked the first officer to "tell them we are in [an] emergency."[1]Шаблон:Rp The first officer told the JFK tower controller that "we'll try once again[;] we're running out of fuel," to which the controller replied, "okay."[1]Шаблон:Rp A few seconds later, the captain again told the first officer to "advise him we are [in an] emergency" and asked if he did so. The first officer replied, "Yes sir, I already advised him."[1]Шаблон:Rp The JFK controller directed the flight to contact the NY TRACON approach controller once more at 21:24:39.[1]Шаблон:Rp The TRACON controller asked the flight to climb once more to Шаблон:Convert. The captain asked the first officer again to "advise him we don't have fuel."[1]Шаблон:Rp The first officer replied, "Climb and maintain three thousand and ah we're running out of fuel sir."[1]Шаблон:Rp The captain once again asked whether the first officer had advised the controller of their emergency, and the first officer replied, "Yes sir. I already advise him[;] hundred and eighty on the heading[;] we are going to maintain 3000 feet and he's going to get us back."[1]Шаблон:Rp

A minute later, the controller instructed the flight to turn to the northeast and asked the flight crew if they had enough fuel to be directed Шаблон:Convert from the airport. First Officer Klotz replied, "I guess so thank you very much."[1]Шаблон:Rp At 21:29:11, Klotz asked the controller if he "can give us a final now...?"[1]Шаблон:Rp The controller said, "affirmative sir[;] turn left heading zero four zero."[1]Шаблон:Rp At 21:30:12, the controller cleared another aircraft for landing.[1]Шаблон:Rp Klotz briefly thought the clearance was directed at Avianca and began to tell Captain Caviedes to change course before the controller corrected him. The controller then asked Avianca to climb to Шаблон:Convert. Klotz replied, "negative sir we just running out of fuel we okay three thousand now okay."[1]Шаблон:Rp The controller continued to direct the flight northward, away from the airport. At 21:31:01, the controller said, "Okay and you're number two for the approach[;] I just have to give you enough room so you make it without ah having to come out again."[1]Шаблон:Rp

At 21:32:38, the cockpit voice recorder (CVR) recorded a temporary interruption in power. A second later, Flight Engineer Moyano exclaimed, "Flame out[;] flame out on engine number four."[1]Шаблон:Rp The CVR recorded another interruption in power one second after that, and Moyano said, "Flame out on engine number three[;] essential on number two or number one."[1]Шаблон:Rp The captain acknowledged. At 21:32:49, Klotz radioed the controller, informing him that the flight had "just ah lost two engines[,] and ... we need priority please."[1]Шаблон:Rp The controller instructed the flight to fly southwest to intercept the localizer.[1]Шаблон:Rp Klotz acknowledged this. The flight crew selected the ILS. At 21:33:04, the controller informed the flight that they were Шаблон:Convert from the outer marker and cleared them for an ILS approach on runway 22L. Klotz acknowledged. That was the final radio transmission from Flight 052. Caviedes asked if the ILS had been selected. Klotz replied, "It is ready on two" at 21:33:23. One second later, the CVR stopped recording.[1]Шаблон:Rp At 21:34:00, the controller tried to radio the flight, asking, "You have enough fuel to make it to the airport?"[1]Шаблон:Rp There was no response.

The NTSB report estimates that around this time, the flight crashed.[1]Шаблон:Rp The aircraft descended without power, clipped several trees and posts, and crashed onto a hill with a 24° slope in Cove Neck, New York.[1]Шаблон:Rp The fuselage partially fragmented into three distinct pieces. The cockpit and forward cabin separated from the rest of the airframe and were hurled over the crest of the hill, coming to a stop Шаблон:Convert from the rest of the wreckage. The rest of the fuselage stopped within Шаблон:Convert after impact. The main fuselage came to rest on the upslope of the hill, facing south, with the forward end extending over the crest of the hill. The right side of the forward end of the fuselage fractured a residential wooden deck.[1]Шаблон:Rp

First response

Residents of Cove Neck immediately called emergency services.[3] Jeff Race, a paramedic and member of New York City's Emergency Medical Service, who lived half a mile from the crash site, was the first rescuer on site.[4] He reported that most passengers were still strapped in their seats and the survivors were crying out for help. Survivors later commented that it took about half an hour for rescue teams to arrive. Initial reports to emergency services reported that a much larger Boeing 747 had crashed.[5] Fire Chief Thomas Reardon of Oyster Bay Fire Company No. 1 was in charge of the initial effort to remove people from the wreckage. In his first call to the Nassau County Fire Commission dispatch, he requested all the help available. Thirty-seven fire and ambulance companies, as well as more than 700 Nassau County police officers arrived to help. Other companies that were not called showed up voluntarily to assist. The swell of support created major problems for extricating survivors.[5]

The crash was only accessible to vehicles via a single residential street.[1]Шаблон:Rp With the surge of rescue personnel who converged on the area, the roads leading to the site soon became choked with traffic. Emergency vehicle drivers abandoned their vehicles contrary to established policy in the course of the rescue efforts.[5] This prevented other vehicles from being able to access the crash area. The road was so impassable, many rescue workers left their vehicles miles away and made it to the scene on foot.[6] Fog also grounded rescue helicopters for two hours. As a result, many critically injured survivors were not evacuated until 23:30. Eventually, four helicopters from the New York City Police Aviation Unit evacuated 21 people from the crash site. Also, major problems occurred with communication by rescuers. Radio frequencies became overloaded, and authorities on site were unable to make command decisions in some cases. The head of surgery of the Nassau County Medical Center was present at the scene, but unable to direct patients to the best locations because many rescuers were radioing the center itself to get advice on where they should send the survivors. Medical professionals on site reported that some hospitals received the most up-to-date information by watching the news coverage. Despite these problems, however, only three of the passengers found alive died of their injuries.[5]

Rescue workers set up two triage areas on the lawn of John and Kay McEnroe, the parents of professional tennis player John McEnroe; the house is known as the Edward H. Swan House.[7][6] A morgue and command post were also set up on their property, which was Шаблон:Convert from the crash site.[5][3] At least six bodies were found outside the fuselage.[8] Firefighters and medics erected ladders next to the airframe wreckage and led passengers down on stretchers and to the triage sites. At these sites, doctors tagged the critically injured patients for immediate evacuation. At least 30 bodies were gathered on the makeshift morgue at the McEnroe property by 03:00 the following morning.[3] Passenger Astrid Lopez was initially believed to be dead due to her severe injuries, and officials placed her body in the morgue.[9] A rescuer soon heard her moans, and she was sent to a hospital. Some medical responders were turned away from the scene by police to help ease the congestion. By 03:30, all the survivors had been evacuated to hospitals. At least one emergency responder was hospitalized as a result of the rescue efforts.[6] Throughout the evacuation, priests were on site, offering encouragement, assisting medical personnel, and performing last rites. Many local New York residents showed up at hospitals with food or blankets, or to volunteer as Spanish interpreters.[10] The New York Blood Center reported collecting 2,000 units of blood, almost triple their goal.[7]

Casualties

The aircraft crashed in front of the house of Sam Tissenbaum.[4]

Of the 158 people on board, 73 died as a result of the crash.[1]Шаблон:Rp The lead flight attendant was the only crew member to survive, while the remaining flight attendants and all three flight crew members died.[1]Шаблон:Rp Of the surviving passengers, 72 adults and children over three years old sustained serious injuries, while two sustained minor injuries.Шаблон:Efn Of the 11 infants, two sustained minor injuries, eight were seriously injured, and one died.[11][12] The surviving flight attendant testified that no communication was made from the cockpit as to the unfolding situation, thus no warning came in the end to assume brace positions. The NTSB report held that, had passengers been warned ahead of time to brace for impact, the severity of some injuries might have been avoided.[1]Шаблон:Rp

The most common serious injuries were multiple lower leg fractures and dislocations, spinal fractures, hip fractures, head injuries, and multiple lacerations and contusions.[1]Шаблон:Rp The NTSB investigators found severe damage on the floor of the cabin, leading many of the passengers' seats to fracture where their legs met the floor track.[1]Шаблон:Rp This fracturing permitted many of the seats to come loose during the impact and aggravated the passengers' injuries. The report posits that the passengers' legs hit the lower seat frames in front of them.[1]Шаблон:Rp At the same time, the seats collapsed and twisted downward and to the left, likely causing hip and spinal fractures. As the impact progressed, the seats, now separated, flung passengers forward into each other and into other wreckage, causing head injuries and lacerations. Passengers holding onto infants reported being unable to either prevent their children from being ejected from their grasp in the impact or locate their children in the darkness afterward. The NTSB held that, had the children been in FAA-approved child seats, many injuries might have been mitigated.[1]Шаблон:Rp Rescuers remarked that some infants were found smiling or seemingly unharmed.[7]Шаблон:Failed verification The NTSB was unable to accurately chart where individual passengers were seated because Avianca only assigned seats to a few passengers, and many who were assigned reported moving after takeoff.[1]Шаблон:Rp

The cockpit was severely damaged in the impact. It struck an oak tree, which penetrated the area occupied by Klotz and Moyano. All the seats occupied by the flight crew were found outside the cockpit. Neither of the pilots' seats had shoulder straps as were required by United States domestic passenger flights.[1]Шаблон:Rp At least one flight crew member was airlifted to Nassau County Medical Center.[8] The NTSB report states that all of the flight crew "died from blunt-force head and upper torso trauma."[1]Шаблон:Rp Five flight attendants also died from blunt-force trauma to the limbs, abdomen, chest, and head.[1]Шаблон:Rp

Investigation

Файл:Avianca52-seat-wreckage.jpg
The structural limitations of the aircraft seats contributed to the passengers' injuries.

The NTSB commenced an investigation, which began shortly after the crash, and concluded with the issuance of its final report on April 30, 1991.[1] Because it involved a Colombian airline, Colombia's Departamento Administrativo de Aeronáutica Civil (DAAC) also conducted an investigation into the accident.[1]Шаблон:Rp

A survey of the wreckage revealed that the tail was mostly intact, and all control surfaces were connected to the pilots' controls.[1]Шаблон:Rp Both wings had been severely damaged on impact and fractured into several pieces. The flaps and slats were found in their extended positions, with the flaps set at 14°. As with the tail, all wing control surfaces were found to have been connected to the pilots' controls. No evidence was found of any control surface failure prior to the crash. Investigators realized that none of the four engines had been under power at the time of impact.[1]Шаблон:Rp As the first responders worked to rescue the passengers, investigators recovered the flight data recorder (FDR) and cockpit voice recorder (CVR) from the wreckage, and brought them to the NTSB laboratory in Washington, DC.[4][1]Шаблон:Rp The FDR was an older oscillographic foil model.[1]Шаблон:Rp In 1989, the FAA began requiring domestic carriers to change to digital FDRs to minimize the errors that foil models produced. This requirement did not apply to international carriers. The Avianca FDR foil was found to have been taped down at some point prior to the flight, and thus was inoperative. The NTSB recommended in the Avianca report that the FAA take an "active role in ensuring upgraded international standards" for flight recorders.[1]Шаблон:Rp The CVR and ATC recordings became vital sources of evidence for the crash. The investigators also looked at meteorological factors that led to flight problems.

The NTSB investigators found that the weather data that the flight crew received in Medellín were 9–10 hours old.[1]Шаблон:Rp Additionally, the alternate airport on the flight plan, Logan International Airport in Boston, was forecast to be below the safe minimum for landing. The NTSB also stated that the flight crew should have been more aware of these problems and cited these deficiencies as evidence of inadequacies in the dispatch of the airplane. The NTSB also found no evidence that the flight crew ever requested weather information en route or communicated with Avianca dispatchers about their fuel status and intents as other flights did.[1]Шаблон:Rp Flight 052 did not make contact with FAA flight service stations or flight watch en route, and the NTSB was unable to determine why. The flight did not express any concern to ATC about their fuel situation during the first two holding patterns that the flight made. The first indication of worry came at 20:09 when the flight crew inquired about delays at Boston.[1]Шаблон:Rp The NTSB posited that the flight crew might have become confused about the "expect further clearance" (EFC) times they were given. This confusion may have been the reason that the flight continued to hold, burning up its reserve fuel to the point where it could no longer divert to Boston.[1]Шаблон:Rp

Investigators also cited the flight engineer for failing to calculate the "minimum approach/landing fuel quantity."[1]Шаблон:RpШаблон:Efn The report references the 360° turn that the flight was ordered to make at 20:54 as evidence that the crew should have known that they were being treated routinely and not given any emergency priority. Instead, the CVR revealed that the flight crew was convinced that they were being given priority. Additionally, the NTSB criticized the first officer for failing to use the word "emergency" as the captain had insisted he do.[1]Шаблон:Rp Compounded with the apparent inability of the captain to hear or understand the radio communications, the NTSB called the situation a "total breakdown in communications by the flight crew."[1]Шаблон:Rp Summarizing, the investigators cited "the flight crew's failure to notify ATC of their fuel situation while holding at CAMRN in order to ensure arrival at the approach fix with an adequate approach minimum fuel level and a breakdown in communications between the flight crew and ATC, and among the flight crewmembers" as the two main factors that led to the crash.[1]Шаблон:Rp

Investigators asserted that the performances by the traffic controllers were proper and that the misunderstandings that were made were reasonable.[1]Шаблон:Rp None of the controllers involved considered the word "priority" or the assertions by the flight crew that they were running out of fuel to be indicative of an emergency. The report provided various examples of the flight crew failing to convey the danger of their situation, even moments before the engines flamed out. Although the investigators felt that the communications from the ATC personnel were "proper," the NTSB voiced concern over the controllers not placing significance on the word "priority."[1]Шаблон:Rp At a public hearing, it was revealed by an unrelated pilot that the emphasis on the word "priority" by the Avianca crew might have come from training and bulletins from Boeing that used the word in relation to fuel emergencies.[1]Шаблон:Rp Avianca also used the word "priority" in its publications on low-fuel status procedures. ATC controllers testified that "Mayday", "pan-pan", and "emergency" were the three phrases that they would respond to immediately.[1]Шаблон:Rp The report also stated that "priority" was defined in the ATC Handbook as "precedence, established by order of urgency or importance."[1]Шаблон:Rp As a result of this linguistic confusion, the NTSB recommended that the FAA work with the International Civil Aviation Organization to develop a standard glossary of clearly defined terms, as well as notify foreign carriers that they must be knowledgeable of ATC rules and procedures.[1]Шаблон:Rp

The NTSB also cited the captain's inability to land on his first attempt as contributing to the crash.[1]Шаблон:Rp The investigation revealed that wind shear was a significant factor in the failed approach, but that other factors probably contributed. The report cited recurring maintenance problems with the airplane's autopilot as a possible factor. If the pilots had been forced to fly manually from Medellín, investigators believed this might have added to exhaustion and stress in the cockpit. For evidence, the NTSB pointed to nine instances where the captain asked the copilot to repeat the ATC instructions or to confirm the aircraft configuration. This stress, investigators asserted, would have degraded the flight crew's performance on final approach.[1]Шаблон:Rp Investigators also looked at the traffic management by the Central Flow Control Facility (CFCF).[1]Шаблон:Rp The CFCF, in communication with NY TRACON, established an airport acceptance rate of 28 aircraft landings per hour that morning. Later, a CFCF supervisor contacted NY TRACON and requested a higher rate of 33 landings per hour. This acceptance rate, investigators concluded, was based on inaccurate weather conditions. The report concluded that these traffic-management problems contributed to the conditions that led to the accident but did not lead directly to the accident.[1]Шаблон:Rp

Controversy

The probable cause of the crash was determined by the NTSB to be "the failure of the flight crew to adequately manage the airplane's fuel load, and their failure to communicate an emergency fuel situation to air traffic control before fuel exhaustion occurred."[1]Шаблон:Rp However, two NTSB members filed dissenting opinions in the report. Jim Burnett voted against the adoption of the report because he felt it did not adequately address the failures of the air traffic controllers or the FAA's role in allowing more traffic than JFK could handle.[1]Шаблон:Rp Christopher Hart filed a partial dissent because he disagreed with the report's findings of a lack of standardized terminology. In his dissent, he wrote that "we do have standardized understandable terminology ... that would have adequately communicated the existence of a dangerous situation, and the problem was that the pilots failed to use this terminology with the controllers".[1]Шаблон:Rp

Colombia's DAAC investigators also disagreed with some of the NTSB's findings. In a comment on a draft of the NTSB's report, the DAAC recommended that the NTSB place some responsibility on the controllers for their "inadequate handling" of the Avianca flight.[1]Шаблон:Rp The DAAC also recommended that the NTSB encourage modifying the EFC system, and that FAA regulations should require an "active flight-following system" to assist flight crews in evaluating weather and traffic delays.[1]Шаблон:Rp

Aftermath

Two male passengers were arrested at North Shore Hospital after a nurse informed police that 46-year-old Antonio Zuluaga had swallowed containers filled with cocaine. Zuluaga, who had a fractured spine, broken ribs, and a dislocated hip, was the second passenger to be found in possession of cocaine packages, after doctors operating on Jose Figueroa on the day after the crash to stop internal bleeding had also discovered packets of cocaine. Zuluaga and Figueroa pleaded guilty to second-degree criminal possession of a controlled substance. Figueroa was sentenced to seven years to life in prison, and Zuluaga was sentenced to six years to life.[13][14][15]

Many crash survivors suffered long recoveries from the physical and psychological traumas they endured.[12] A month after the crash, an orderly caravan of around 1,000 vehicles drove to JFK while some demonstrators laid wreaths in the international terminal lobby to protest the handling of the flight.[16] Some survivors sued the FAA, accusing the agency of failing to ensure the flight's safety.[17] In July 1990, Avianca offered $75,000 to each crash survivor or the relatives of those killed.[18] The U.S. government eventually joined Avianca and reached a settlement estimated at over $200 million in damages to the victims.[19]

The same summer, Avianca flights declared two notable fuel emergencies. The first happened in June, when a flight declared a "minimum fuel situation" and landed with only 10 minutes' worth of fuel left.[20] The second happened in August, when Avianca Flight 020 declared it had "only 15 minutes of fuel left".[20] Confusion arose as to what the pilot meant, but controllers declared an emergency pre-emptively and cleared the plane to land immediately. The flight was later found to have had over two hours' worth of fuel remaining.[21]

Avianca has not retired the flight number. Avianca Flight 052 is, as of 2023, a flight from Lima to Bogotá. However, Avianca has changed the numbers for the now non-stop flights from El Dorado to JFK, designated as Avianca Flight AV244 and Flight AV020, operated by an Airbus A330 and an Airbus A319, respectively.Шаблон:Citation needed

In popular culture

  • The events of Flight 052 were featured in "Missing over New York", a season-two (2005) episode of the Canadian TV series Mayday[22] (called Air Emergency and Air Disasters in the U.S. and Air Crash Investigation in the UK and elsewhere around the world). The dramatization was broadcast with the title "Deadly Delay" in the United Kingdom, Australia, and Asia. The flight was also included in a Mayday season-eight (2009) Science of Disaster special titled "System Breakdown",[23] which looked at the role of air traffic controllers in aviation disasters.
  • Avianca Flight 052 was featured on the MSNBC network's Why Planes Crash series, in an episode titled "Human Error".[24]
  • The impact of cultural differences between the Colombian pilots and American air traffic controllers was discussed in Malcolm Gladwell's book Outliers.[25]
  • Stock footage of the plane wreckage was used in the 2004 film The Day After Tomorrow.[26]
  • Survivor Nestor Zarate wrote a book about the flight, titled 20 minutos antes... 20 años después (20 Minutes Before... 20 Years Later).[27]
