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 04/21/96, at 39,000 feet, on an IFR flight from albuquerque, NM to teterboro, NJ, the crew noticed a drop in oil pressure of the right hand engine. At the same time, they noticed fumes in the cockpit. They shut off the right hand bleed air valve, verified the fumes stopped, then secured the right hand engine. The crew diverted to Springfield, IL where they landed without further incident. The two crewmembers and one passenger sustained no injuries. The crew did not declare an emergency. The right hand engine had maintenance performed three flight hours previously and the #3 air/oil seal had been replaced. Maintenance personnel found evidence that oil was leaking from the area of the #3 seal. The #1 seal was found to be deteriorated with some oil seepage. Maintenance personnel believed that the #1 seal was allowing air leakage.
