Narrative:
The Boeing 747, named "Emperor Vikramaditya", touched down at Delhi after a flight from London. On application of reverse thrust, a failure of the no. 1 engine pylon to wing attachment caused this engine to tilt nose down. Hot exhaustion gasses caused a fire on the left wing. 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."
