Probable cause

Failure of the pilot to maintain directional control which resulted in an inadvertent ground swerve.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Loss of control - on ground/waterLanding - flare/touchdown
Directional control - not maintainedPilot in commandCause
Ground loop/swerve - inadvertentPilot in commandCause
Gear collapsedLanding
Landing gear,main gear - overload

Analysis

The pilot reported that 'just as the main gear touched (the runway) the aircraft turned to the left as if the left brake had locked or had been pushed by a strong left crosswind . . .' Subsequently, the aircraft's right main landing gear collapsed, followed by the nose gear, then the aircraft skidded to a stop on the runway. Winds at the uncontrolled airport were reported to be aligned with the runway at about 8 knots. A post-accident examination of the left wheel and brake assembly revealed no indication of a pre-accident malfunction. An inspection of the right main landing gear truss assembly indicated it had failed in overload. No progressive failure was evident.
