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. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
