Aircraft Accident/Incident Report

Tillamook, Oregon 97141
Friday, July 28, 2000 12:00 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot entered a downwind for runway 31 and noted calm winds from a nearby smoke stack and the midfield windsock. He established the aircraft on short final with three notches of flaps and 65 knots of airspeed for a three-point landing. Touchdown on the main wheels occurred just slightly before the tailwheel touchdown. Once on the runway, the pilot applied full aft elevator, raised the manually operated flaps, and applied light braking during which the aircraft suddenly veered left. The pilot reported that rudder control was inadequate, and that applying power worsened the yaw. He then retarded the throttle to idle, applied full up elevator, hard right rudder and hard braking, during which the aircraft continued to yaw left and eventually impacted the right wingtip. The pilot reported that there was no mechanical malfunction with the aircraft during the event.

NTSB Probable Cause Narrative

The pilot's failure to maintain directional control.
