The aircraft had reached its cruise altitude of 8,500 feet when the engine smoothly quit. The pilot contacted a nearby airport control tower, reported the power failure, and said he needed to land. The local controller cleared the flight to land on any runway. Shortly thereafter, the pilot radioed that he would not make the field and landed gear-up in a dry wash area. During the landing, the aircraft collided with trees and an embankment. Examination of the airplane disclosed that the mixture control cable was fractured and disconnected from the cable's rod-eye end, which was still attached to the mixture arm of the fuel metering unit. The break in the cable was at the engine rod-eye end of the flexible cable at the point where the cable is swaged onto the rod. A metal outer sheath slides over the rod and the eye end of the rod is longitudinally adjustable so that the rod and cable can ride inside the outer metal sheath to provide support against bending loads. The length adjustment nuts on the rod-eye end were found adjusted all the way down so that the cable to rod swage point was outside the sheath at the full rich mixture setting. Metallurgical examination of the cable found that it failed in fatigue due to excessive and repetitive bending. According to the maintenance records, the mixture control cable was replaced at the last annual inspection on June 2, 1998, 99 hours prior to the accident. No other anomalies were found with the engine or its related systems.
Probable Cause: A loss of engine power due to the fatigue failure of the mixture control cable, which was due to the improper installation and adjustment of the cable 99 hours prior to the accident.
