## Probable cause

a loss of engine power due to the failure of the single-drive dual magneto that resulted from inadequate lubrication of the breaker cam.  Also causal was the improper maintenance by other maintenance personnel during a recent inspection, which should have detected the lubrication deficiency.   A contributing factor in the accident that likely exacerbated the pilot's injuries was his decision not to wear the installed shoulder harness.
