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.

(.19) On November 6, 2002, approximately 1200 central standard time, a Piper PA-31-35 twin-engine airplane, N698VW, was substanially damaged following an in-flight engine fire while in cruise flight near near Kerrville, Texas. The airplane was owned and operated by the private pilot under TITLE14 code of federal regulations part 91. The private pilot, sole occupant of the airplane, was not injured. Visual meteorological conditions prevailed for the cross-country flight, and a flight plan was not filed. The personal flight departed castroville, Texas, approximately 1130. The pilot reported to the FAA inspector, who responded to the accident site, that the airplane was approximately 25 miles from the Kerrville Municipal/Louis Schreiner field airport when the right engine lost power and the EGT decreased. The pilot performed the emergency procedure and feathered the propeller on the right engine. The pilot landed the airplane at Kerrville without further incident. During an examination of the airplane by the pilot, a mechanic, and the FAA inspector, oil was found from the right engine propeller aft to the right vertical stabilizer. The outboard portion of the right flap, the right gear door, and the right wing locker were destroyed by the in-flight fire. There was thermal deformation of the aft right wing spar. (-23) engine oil leaked from the crankshaft front oil seal. The oil was ignited by the turbo charger or exhaust gas. The resultant fire burned the wing locker, lower skin, landing gear door and wing flap. Pilot heard a loud bang and noticed an engine fuel flow discrepancy. Pilot shut down and feathered right engine. Aircraft was landed without further incident.
