Analysis

The pilot had completed a local personal flight and was on taxiway 'C,' and was returning to the parking ramp, when without warning the left main landing gear collapsed. Examination of the airplane and the landing gear assembly showed that the left main landing gear down-lock end fitting assembly and the retention bolt had broken. The landing gear examination of the locking linkage failed to establish installation specification prior to the accident. A visual examination of the failed bolt assembly also failed to disclose pre-existing cracking in the bolt structure. A review of the maintenance logbooks revealed that recent maintenance had been performed on the landing gear assembly 18 hours before the accident.
