Aircraft Accident/Incident Report

Lone Pine, California 93545
Tuesady, March 10, 1998 9:00 PST

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that as the aircraft climbed through about 3,000 feet agl the engine began to misfire, then lost almost all power. Following an unsuccessful attempt to restore normal engine power, the pilot set up for a glide toward an abandoned airfield. With insufficient altitude to make the airfield, the pilot landed in a pasture and collided with bushes and hidden obstacles in the grass. Both magnetos were found loose in their clamps by technicians from an aircraft recovery firm who retrieved the wreckage. Logbook review disclosed that the engine had accumulated 67 hours since a major overhaul, which was accomplished May 1, 1997. This was the last maintenance recorded in the logbooks.

NTSB Probable Cause Narrative

The failure of maintenance personnel to properly tighten the magneto clamps during installation of the engine on the aircraft following engine overhaul.
