N1963, the aircraft involved

The American Airlines Boeing 727-23, registration Шаблон:Airreg overran the departure end of Runway 9 when landing at Harry S. Truman airport. The aircraft struck an Instrument Landing System antenna, crashed through a chain link fence, and traveled another Шаблон:Convert until stopped by a gas station. The aircraft was destroyed.

The airport in St. Thomas was notorious among pilots for its short (Шаблон:Convert) runway. In fact, the Boeing 727 was the heaviest aircraft type authorized to use it, and even then it was only authorized in one direction.

Ultimately, the NTSB attributed the crash to pilot error on the approach. The maximum flap setting of 40 degrees was never applied, which meant that the aircraft's speed was Шаблон:Convert higher than V_REF as it crossed the runway threshold. This, combined with the fact that the aircraft 'floated' from turbulent winds in the area, meant that it was already Шаблон:Convert down the runway at the point of touchdown. The pilots did not brake, and proceeded to apply full throttle three seconds after touchdown in an attempt at a go-around. However, they were unable to reach takeoff speed because the 727's engines are slow-responding, taking about 6.6 seconds to power up. After five seconds of waiting for power, and with only Шаблон:Convert of runway left, the pilot panicked, according to the report, and applied full brakes. Further, the pilot forgot to apply reverse engine thrust until immediately before impact.

Ultimately, the aircraft ran off the end of the runway and into a Shell gas station, killing 37 (35 passengers and 2 flight attendants) of the 88 on board. Thirty-eight other passengers and crew were injured, and one person on the ground was seriously injured. The probable cause was the captain's actions and his judgment in not being aware that when he touched down Шаблон:Convert down the Шаблон:Convert runway, he did not have enough distance to perform a go-around.

As a result of the crash, American Airlines ended all jet flights to St. Thomas, flying instead to St. Croix (which had a 7,600 foot runway at the time). American Airlines passengers were then flown to St. Thomas in Convair 440 propeller-driven aircraft from St. Croix, with these flights being operated by a wholly owned subsidiary, American Inter-Island Airlines. The Convair 440 aircraft were owned by American Airlines and flown and maintained via contract by Antilles Air Boats, a seaplane operator in the U.S. Virgin Islands. Jet flights operated by American resumed when a new runway at St. Thomas was constructed with a length of Шаблон:Convert.
