Probable cause

The partial disconnection of the electrical connector at the torque sensing unit.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

FireTakeoff - roll/run
Fuel injection control,torque box - disconnectedCause
Combustion assembly - fireCause
Aborted takeoff - performedPilot in command
Emergency procedure - performedPassenger

Analysis

During the takeoff roll, the pilot observed the torque indications of the right engine drop to 80 percent and the fire warning light for the same engine illuminate. The pilot aborted the takeoff and deplaned the passengers. Aircraft fire and rescue personnel extinguished the fire in the right engine. A teardown and analysis of the right engine revealed that the electrical connector of the torque sensing unit became loose. The loose connection resulted in excess fuel being dumped in the engine causing a pooling fire.
