The engine failure, which occurred to N661US on Oct 23, took place as the Pratt & Whitney PW4056-powered aircraft was climbing through 5,000 ft.

The crew heard a large compressor stall and muffled explosion followed by the immediate rollback of engine number two. The engine fire light then illuminated and, with this still indicating at idle power setting, the crew activated the fire bottle.

Having successfully extinguished the fire, the crew executed a text book fuel dump procedure after deciding against an over-weight landing. On return to Detroit post-flight inspections revealed severe damage to the engine and wing with large holes noted in the cowling as well as damage to slats, flaps and aileron.

As an indication of the violence of the failure, witnesses also say the engine was askew on the pylon. Investigations continue into the cause of the engine failure
