Aircraft Accident/Incident Report
W. Yellowstone, Montana 59758
Friday, July 18, 1997 16:30 MDT
NTSB Narrative Summary Released at Completion of Accident
The private pilot attempted to compensate for crosswind conditions during final approach in the twin-engine airplane with the use of power. He began to drift off the east (left) side of the runway, and he stated that the right engine did not respond to throttle inputs during the landing. He lost directional control of the airplane and impacted rough, grassy terrain off the edge of the runway. The landing gear collapsed and the airplane was substantially damaged. Examination of both propellers revealed damage consistent with applied power on the left engine, and no power on the right engine. An examination of the maintenance records revealed that the engine had recently been rebuilt by the manufacturer and installed on the airplane. Prior to the accident flight, it underwent an annual inspection and was operated for 6.2 hours during six flights with no problems noted. An examination of the right engine throttle controls and a functional test of the right engine did not reveal any evidence of preimpact mechanical discrepancies that would have resulted in a power loss or hesitation.
NTSB Probable Cause Narrative
The pilot's failure to maintain directional control during landing when asymmetric power was applied. A factor was the crosswind conditions.
