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.

Narrative: on March 24, 1995, a shorts 3-60 was climbing through 1200 feet when the right engine itt began a rapid climb. The pilot reduced power, but that did not change the climbing itt. Max itt was noted to be 900 degree c. the pilot heard two bangs, which he thought were compressor stalls and smoke was noted in the cabin area. The engine was shut down and the prop feathered w/o incident. The co-pilot declared an emergency and returned to guam w/o incident. Initial reports from the operator indicated that the engine was full of oil which may be the result of a blocked oil scavenge line from the gearbox. It was speculated that coating material inside the gearbox may have flaked off and blocked the oil return line. After draining the oil and inspection, the a/c was ferried to saipan w/o incident. The gas generator was removed and replaced with a rental unit. The gas generator is awaiting further investigation by pratt & whitney and the FAA. No further info available at this time. Incident IWP1395010. No pilot deviation no NMAC. Closed.
