Aircraft Accident/Incident Report

Bremerton, Washington 98337

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that he performed a normal wheel landing. During the landing roll, the left main gear leg failed. Post-accident inspection revealed that the attachment bolt from the gear leg broke in two pieces. During the metallurgical examination, the specialist found that three major fracture zones were present. Two of the zones were fairly flat and propagated on a plane that was perpendicular to the bolt axis, typical of fatigue progression. One of the zones was covered with heavy accumulation of oxides and corrosion deposits. The other zone was free of oxidation and deposits. The third zone displayed a fracture propagation on a 45 degree slant. This zone was typical of a final overstress separation. The fatigue zones occupied about 75 percent of the bolt cross section at the fracture location. The specialist reported that the presence of oxide and corrosion deposits suggested an 'old crack.' There was no evidence found of thread stripping. Maintenance records indicate that since the time of manufacture in 1978, the aircraft had accumulated a total time of 77 hours. During this time, there were several years in which the aircraft had not been operated.

NTSB Probable Cause Narrative

Failure of the landing gear attach bolt due to fatigue failure resulting in the left main landing gear collapsing.
