Read the full NTSB narrative
The pilot stated that the airplane developed engine problems during the cross-country flight and he elected to make a precautionary landing to a private airstrip. He reported that the landing touchdown was normal, but during the rollout he heard a "loud pop sound from under the seat" 4-5 seconds before the right main gear collapsed. Post accident examination of the airplane’s landing gear, by representatives from the Federal Aviation Administration (FAA) and the operator, revealed that the center gear attach bolt and corresponding locking nut for the right main landing gear leg was missing. The bolt was later recovered, however, the locking nut was not found. The bolt was intact and nominal wear was noted. There was no evidence of thread failure or significant mechanical damage. The operator reported that the absence of the nut and bolt allowed the landing gear leg to separate from its corresponding attach assembly. It was not determined why the missing nut separated from the bolt and landing gear assembly.
