Aircraft Accident/Incident Report
Oak Harbor, Washington 98278
Wednesday, July 18, 2001 19:00 PDT
NTSB Narrative Summary Released at Completion of Accident
The accident aircraft was sequenced in the pattern with a Navy P-3 (Lockheed 4-engine) aircraft that was doing touch-and-go landings. While the accident aircraft was on short final, the aircraft rolled violently to the right about 60 to 90 degrees. The pilot attempted to recover from the roll, however, during the maneuver, the right wing struck the runway surface. The aircraft touched down, collapsing the nose gear. The aircraft slid approximately 60 feet before coming to rest on the runway's edge.
NTSB Probable Cause Narrative
The pilot's inadequate remedial action while on final approach. The encounter with wake turbulence was a factor.
