Aircraft Accident/Incident Report
Wheeling, Illinois 60090
Wednesday, April 11, 2007 11:15 CDT
NTSB Narrative Summary Released at Completion of Accident
The pilot reported that upon reaching approximately 75 knots during the takeoff roll, he felt a surge from the left engine. He noted that the "surging continued and positive directional control could not be regained," at which point he closed the throttles and elected to abort the takeoff. The pilot attempted to maintain directional control by using differential braking and rudder inputs. The airplane subsequently departed the left side of the runway and impacted an airport sign, causing the nose landing gear to collapse, before coming to rest. Post accident testing of the left propeller governor unit revealed that the component pressure gain was approximately one-half of the manufacturer's specification, resulting in the unstable engine operation.
NTSB Probable Cause Narrative
Partial failure of the left engine propeller governor during the takeoff ground roll. Factors included that directional control was not possible by the pilot which subsequently led to a collision with an airport sign.
