London - Brussels

On June 18, 1972 at 05:11 PM, London - Brussels experienced a crash involving Hawker Siddeley HS.121 Trident, operated by British European Airways - BEA, with the event recorded near London-Heathrow London Metropolis.

The flight was categorized as scheduled revenue flight and the reported phase was takeoff (climb) at a airport (less than 10 km from airport) crash site.

118 people were known to be on board, 118 fatalities were recorded, 0 survivors were identified or estimated. This corresponds to an estimated fatality rate of 100.0%.

Crew on board: 9, crew fatalities: 9, passengers on board: 109, passenger fatalities: 109, other fatalities: 0.

The listed crash cause is human factor. Following a normal takeoff roll on runway 28R, the aircraft rotated 42 seconds after brakes were released and lifted off 2 seconds later at 145 knots IAS. At 63 seconds the autopilot was engaged 355 feet above the runway at 170 knots IAS; the IAS speed lock was selected shortly thereafter. At 74 seconds the aircraft started a 20° banked turn to port towards the Epsom Non-Directional Beacon (NDB). At 83 seconds the captain reported 'Climbing as cleared'. He was then instructed to change frequency and contact London Air Traffic Control Centre. At 93 seconds the noise-abatement procedure was initiated. On the assumption that the captain was the handling pilot, this would involve the second officer selecting the flaps fully up and operating the thrust levers to reduce power to the pre-calculated figure. At 100 seconds the captain called 'Passing 1500' and at 103 seconds the aircraft was cleared to climb to Flight Level 60. This message was acknowledged by the captain at 108 seconds with the terse call 'up to 60'. This was the last message received from the flight. At second 114 when the airspeed was 162 knots and the altitude 1,772 feet, the droop lever was selected up putting the aircraft into the area of the stall as the droop started to move. At second 116 the stick-pusher stall recovery device operated, causing the autopilot automatically to disengage and the nose of the aircraft to pitch down and the stick-push to cease as the incidence decreased. Since the elevator trim would stay at its position on autopilot disengagement which at that speed with the droop up would be - the incidence then increased causing a second stick-push at second 124 and a third at second 127. At second 128 the stall recovery system was manually inhibited by pulling the lever. The aircraft then pitched up rapidly, losing speed and height, entering very soon afterwards the true aerodynamic stall and then a deep stall from which at that height no recovery was possible. Impact was at second 150 in a field next to the A30 motorway. The aircraft was totally destroyed and none of the 118 occupants survived the crash.

Aircraft reference details include registration G-ARPI, MSN 2109, year of manufacture 1964.
