Engine Torque Indication Anomaly During Takeoff of ATR 72

Casualties unknown • EYKA, PL

During a takeoff roll at Kaunas Airport, the crew of an ATR 72 aborted the flight after noticing a failure in the right engine's torque readings.

What happened

On April 29, 2020, an ATR 72, registration SP-SPA, was performing a takeoff at Kaunas Airport (EYKA). As the crew increased engine power, they observed that the torque (TRQ) value for the right engine failed to increase. In response to this anomaly, the crew elected to abort the takeoff.

Following the incident, maintenance personnel inspected the aircraft. The technician reset a fuse, cleaned the electrical connector for the TRQ sensor, and performed subsequent TRQ indication tests. The tests confirmed that the readings were functioning correctly, and the aircraft was subsequently cleared for flight.

The investigation

The investigation focused on the electrical connection of the torque sensor and the subsequent maintenance actions taken to restore proper functionality to the engine instrumentation.

Probable cause

The probable cause of the event was the contamination of the electrical connector pins for the TRQ sensor.
