Aircraft Accident/Incident Report

Mesa, Arizona 85539
Saturday, May 9, 1998 10:45 MST

NTSB Narrative Summary Released at Completion of Accident

The airplane, which the pilot owned and operated, experienced a total loss of engine power while descending for a practice forced landing. The pilot indicated that no adequate landing site was available within gliding distance, so he landed in the rough terrain of a dry wash shearing off both main landing gear. The airplane was recovered and examined. A clamp that had been welded onto a bracket which was secured to the engine case was found broken. The clamp/bracket assembly supported the throttle cable. When the weld broke subsequent movement of the cockpit throttle control had no effect upon the engine's rpm. The pilot described the weld as having been 'bad,' and it was not a Piper manufactured component.

NTSB Probable Cause Narrative

Failure of a weld in the engine's throttle control support assembly due to inadequate maintenance which was the ultimate responsibility of the owner-pilot. Contributing factors were the presence of rough terrain, the lack of a suitable forced landing site, and the pilot's inadequate in-flight planning.
