A Northwestern Air Lease British Aerospace Jetstream 32, registration C-FNAE performing flight J3-906 from Fort Smith,NT to Hay River,NT (Canada), was climbing out of Fort Smith about 10 minutes into the flight when the crew received a fire warning for the left hand engine (TPE331). A visual inspection of the engine showed no fire or smoke, the engine gauges all showed normal values, the crew therefore decided to keep the engine running and returned to Fort Smith, Fort Smith's volunteer fire brigade was called out for the landing. The aircraft landed safely. During taxi the crew shut the engine down, the fire indication still persisted so that the crew discharged both fire bottles, smoke was seen coming from the tail pipe of the engine afterwards prompting ground personnel to discharge a dry chemical fire extinguisher into the tail pipe as well.

The Canadian TSB reported maintenance found no evidence of fire and determined the fire indication was false. The engine however was found seized as result of accumulation of agent particles and the shock cooling associated with the discharge of the dry chemical extinguisher. The engine needed to be replaced.
