Probable cause

The total loss of engine power for reasons that could not be determined based on the available information.

NTSB analysis

The private pilot reported that, during landing at a high density altitude airport, the airplane bounced. He applied full engine power to go around; however, the engine experienced a total loss of power. The pilot attempted to restart the engine but was unsuccessful. The airplane subsequently touched down and overran the runway. Examination of the airplane revealed that the fuel mixture control arm in the engine compartment was striking an improperly-routed hose; however, the full travel of the mixture arm did not appear to be impeded. The examination of the engine did not include removal of the spark plugs or fuel controls; therefore, the reason for the loss of engine power could not be determined.
