From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) On 11/04/05, alpine aviation inc., d/b/a alpine air, enroute from fca to bil with the pilot onboard, at 13,000 ft. started developing right engine problems. The pilot first noticed that the right engine torque indicator was fluctuating and then the oil pressure indicator gage began fluctuating. The pilot shined his flashlight out to see any indication of oil leakage and none was noticed. The pilot then proceeded to reduce power to the right engine, when there was a loud bang and saw fire balls out the exhaust stacks. The pilot then performed emergency engine shut down procedures, contacted slc center and diverted to gtf and landed without incident. A postflight inspection revealed no oil indication on the engine oil dipstick. The pilot stated that prior to the first flight of the day, the oil level was checked and was noted around the 3 mark. The right engine will be torn down and inspected for the cause of the failure. The operator will submit a SDR to this office and will be filed with this report as soon as the inspection of the engine is completed. This incident is considered closed.
