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."
