Occurrence
On 17 July 2018, at 18:59 UTC, a Bombardier DHC-8-402 was departing from EPWA (Warsaw) to EPGD (Gdańsk). During the takeoff roll, the crew observed that the RPM indication for engine No. 2 stopped at 57%. The takeoff was immediately aborted. The crew notified the operator's Maintenance Control Center (MCC) and other relevant services. An Aviation Safety Report (ASR) was filed.
Cause
The investigation determined that the abnormal engine operation was caused by an internal fault of the Fuel Metering Unit (FMU).
Corrective Actions
Technical personnel replaced the faulty FMU with a new unit. An engine run at maximum power was performed and results were normal. The event was recorded in the operator's SMS database, classified according to the operator's criteria, and included in the operator's Safety Performance Indicators (SPI). No safety recommendations were issued by the investigation commission.
