Aircraft Accident/Incident Report

Arlington, Washington 98223
Saturday, July 12, 1997 9:50 PDT

NTSB Narrative Summary Released at Completion of Accident

The tailwheel equipped airplane incurred substantial damage during a nose-over on the landing roll following the separation of the right-main wheel from its associated strut. The pilot reported that he touched down on his main wheels on the sod runway, bounced once, then 'seemed to settle into a normal run-out'. The pilot stated that 'a second or two later' he felt a heavy yaw to the right as the right landing gear dug into the turf. The landing-gear axle was found to have failed. The landing-gear strut dug into the turf, causing the aircraft to nose over.

NTSB Probable Cause Narrative

Failure of the right-main landing gear axle after landing.
