The aircraft
The aircraft, operated by Dan Air Services Ltd, was a Hawker Siddeley HS 748-108 series 2A (construction/manufacturer's serial number: 1560, registration: G-ASPL) that had its first flight in 1964. Skyways Coach-Air was its original operator. Dan-Air acquired the aircraft from Skyways International, Skyways Coach-Air's successor, in 1972. At the time of the accident, it had flown 34,592 hours.[1]
Accident
The aircraft departed
During its initial descent towards its destination, the attendant reported that one of the cabin door's indicators was showing an unlocked condition. Shortly afterwards, the right hand rear door (the baggage door) opened, detached itself from its hinge mounts and became lodged on the leading edge of the right horizontal tailplane. Later reconstruction of the aircraft's flight path from flight recorder evidence indicated that cabin decompression occurred when it was in the vicinity of Market Bosworth.[5]
The aircraft became uncontrollable and went into a steep dive, which terminated in several abrupt
Shortly after, the radar controller who handled flight 240 noticed that the aircraft was turning right beyond its assigned heading; however, his attempts to contact the crew proved futile. Approximately three minutes after the last distress message, reports began to reach ATC from the police of an aircraft crash.[5]
Several people on the ground witnessed the final moments of flight 240. The consensus of their evidence was that the stricken plane was lower than usual compared with other aircraft
The wreckage was found scattered across several fields, approximately 1 mi (1.6 km) northeast of the village of Nailstone.[4][5]
Cause
It was concluded that the accident had been caused by the baggage door becoming lodged on the leading edge of the right tailplane after it had opened and detached. This changed the aircraft's aerodynamic characteristics so that it became uncontrollable. This in turn resulted in overstressing of the wings and tailplane leading to inflight structural failure, with both wings and tailplane detaching from the fuselage. Contributory factors were the mis-rigged state of the door operating mechanism, which allowed the top and bottom pairs of catches to lose synchronisation, and failure of the door warning indicators to give the crew enough time to respond to door safety alerts.[1][4][5]
