Probable cause
Loss of directional control for an unknown reason.
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.
Analysis
As the pilot was landing, the aircraft veered to the right, the left main landing gear & strut separated, and the aircraft settled on the left wing. According to the pilot, the right brake locked, which cause the aircraft to yaw to the right. A post-accident inspection of the right brake did not reveal any reason for the brake to lock. The wheel was free to rotate & the master cylinder appeared to be in proper working order.
