## Probable cause

THE PARTIAL DISCONNECTION OF THE ELECTRICAL CONNECTOR AT THE TORQUE SENSING UNIT.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Fire, takeoff - roll/run
  - fuel injection control,torque box - disconnected (cause)
  - combustion assembly - fire (cause)
  - aborted takeoff - performed, pilot in command
  - emergency procedure - performed, passenger

## 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.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Incident 19911011062509I](https://openairdocs.org/incident/19911011062509I), Oct 11, 1991: Bag JETSTM3101, Dallas-Ft Worth, TX. Right engine power loss on takeoff. Aborted. Exhaust fire. Departed end of runway. Passengers evacuated.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
