Probable cause:
It was determined that the center fuel tank had not been filled nor purged since March 9. It is possible that fuel vapors that accumulated in the central fuel tank ignited with the combination of high temperature (actual OAT 35° C) and a defect electric wire.

Captain / Total flying hours:

Circumstances:
After touchdown at New Delhi-Indira Gandhi Airport following an uneventful flight from London-Heathrow Airport, the crew started the braking procedure and activated the thrust reversers when the pylon of the engine n°1 failed. The engine partially detached, causing a fuel line to rupture and the fuel to ignite. The aircraft was stopped after a course of almost 3 km and all 215 occupants were evacuated safely. The fire was extinguished but the aircraft was damaged beyond repair.
Probable cause:
The accident was caused due to the migration of the improperly installed diagonal-brace aft fuse-pin of the No.1 engine from its fitting which substantially reduced the load carrying capability of the engine fittings resulting in failure of the upper-link forward fuse pin due to excessive loads on account of probably improper landing leading to a partial separation of engine and fire.

The aircraft struck an electric pole and crashed, bursting into flames. Seven passengers were killed while 17 other occupants were injured. The aircraft was destroyed.

Circumstances:
During the takeoff roll at Luang Namtha Airport, after V1 speed, the crew started the rotation when the flight engineer decided to abort the takeoff procedure without any coordination with both pilots. Unable to stop within the remaining distance, the aircraft overran and collided with a building. All 35 occupants were rescued while one person on the ground was killed.
Probable cause:
It was determined that the crew failed to prepare the flight according to published procedures. Prior to departure, the crew incorrectly calculated the weight and balance and it was determined that the aircraft has been incorrectly loaded as the CofG was too far forward, out of the enveloppe. Poor crew coordination was a contributing factor.

A passenger was killed while all six other occupants were injured.
Probable cause:
It was determined that the total weight of the aircraft was 238 kilos above the MTOW and the CofG was too far aft the limit, out of the flight envelope. In such conditions, the crew was unable to maintain flight control.
