Aircraft Accident/Incident Report

Kill Devil Hill, North Carolina 27948
Tuesady, September 1, 1998 17:02 EDT

NTSB Narrative Summary Released at Completion of Accident

The pilot stated he applied full power and was climbing to a higher altitude as he crossed a bay. The engine suddenly made a loud noise and lost power. He turned back to the closest shore and an airport. He was unable to reach the airport and made a forced landing in a sandy area, at which time the aircraft nosed over. Postcrash examination of the engine by an FAA inspector showed the No. 1 cylinder exhaust valve head had broken off from the stem resulting in the No. 1 piston breaking and the No. 1 connecting rod bending. The No. 1 exhaust valve had accumulated 1,527 flight hours since new.

NTSB Probable Cause Narrative

Failure of the number one cylinder exhaust valve resulting in loss of engine power and a forced landing on unsuitable terrain at which time the aircraft nosed over.
