Eastern Airlines Flight 401

Lockheed L-1011, December 29, 1972, Miami, Florida. Eastern Airlines Flight 401 crashed into the Florida Everglades while on approach to Miami International Airport. The National Transportation Safety Board (NTSB) determined that the crash was the result of an inadvertent autopilot disconnection that went unnoticed by the flight crew as they were attempting to correct an unsafe landing gear position indication. The NTSB determined that the uncommanded descent into the Everglades was the result of the flight crew's failure to monitor the airplane's flight path and an improper division of duties on the flight deck while troubleshooting an anomalous system indication. Of the 163 persons on board, 112 were killed in the crash. This accident was one of the precipitating accidents leading to the development and industry-wide adoption of flight crew resource management philosophies and training.

Air Florida Flight 90

Boeing 737-200, January 13, 1982, near Washington National Airport, Washington, D.C. On January 13, 1982, Air Florida Flight 90, a Boeing Model 737-200 series airplane, crashed shortly after takeoff from Washington National Airport, Washington, D.C. The Boeing Model 737-200 experienced difficulty in climbing immediately following rotation and subsequently stalled. The airplane struck the heavily occupied 14th Street Bridge connecting Arlington, Virginia with the District of Columbia and then crashed into the ice-covered Potomac River. Seventy of the 74 passengers and four of the five crew were killed along with four occupants of vehicles on the bridge. Loss of control was determined to be due to reduction in aerodynamic lift resulting from ice and snow that had accumulated on the airplane's wings during prolonged ground operation at National Airport. Contributing to the airplane's poor takeoff performance was a significant engine thrust shortfall believed to be due to anomalous engine thrust indications on both engines caused by engine pressure ratio (EPR) Pt2 probes which were believed to have been plugged with snow and ice during ground operation.

Avianca Flight 052

On Thursday, January 25, 1990, at approximately 21:34 local time, Avianca Airlines Flight 052, a Boeing 707-321B, crashed in a wooded residential area in Cove Neck, Long Island, New York. There were 158 people on the flight including passengers and crew: 65 of the 149 passengers, and 8 of the 9 crew were killed. AVA052 was a scheduled international flight from Bogota, Colombia, to John F. Kennedy (JFK) International Airport, New York.

Poor weather conditions in the Northeast of the US led to the flight being put into holding three times for a total of 1 hour and 17 minutes. During the third hold period the flight crew reported that the airplane could not hold longer than 5 minutes, as it was running out of fuel, and that it could not reach its alternate airport, Boston-Logan International. Subsequently, the flightcrew executed a missed approach to JFK. While trying to return to the airport, the airplane had a loss of power to all four engines and crashed approximately 16 miles from the airport.

American Eagle Flight 3379

In December, 1994, a British Aerospace Jetstream 3100 crashed while on an instrument approach to Raleigh-Durham, North Carolina. The National Transportation Safety Board (NTSB) identified an incorrect crew response to a momentary propulsion malfunction indication as a primary cause of the accident. The captain incorrectly assumed that an engine had failed, and failed to follow approved crew procedures for an engine failure, for a single-engine approach and go-around, and for stall recovery.
