Analysis

During takeoff at kodiak, AK, the wheel & lower shaft of the left strut assy separated from the acft. The plt stated that when he was retracting the gear, he felt a bump & got an unsafe gear light. He immeditaely extended the gear & flew by the tower & was informed that the left gear appeared to be missing. The plt then flew to Anchorage where he could land on a foamed rwy. He was unable to retract the gear. Before landing, he shut down & secured the left eng. The left wing received minor damage during the landing. An exam of the top main gear bearing revealed that 2 of 4 retaining pins, pn 01821-06, were missing & the other 2 were sheared off. An exam of the right main gear retaining pins revealed that 2 had cracks in the neck region. Earlier on the same day of the incident, the acft had an unsafe gear indication. Maintenance personnel had inspected, removed, cleaned, greased & reinstalled all actuating rods & had adjusted the left gear uplock. The acft was then released for a test flt, on which, the incident occurred.
