Analysis

After landing at a mining camp airstrip, the right landing gear failed causing the aircraft to ground loop. Examination of the broken gear part revealed the original fracture to be a fatigue fracture. The initial crack in the gear leg ran parallel to the gear bolt hole. The acft was inspected 80 hrs before the failure.
