Narrative:
A ground crewman was injured when rotating the propeller before engine start, and the propeller reversed in a 180-degree kickback. The pilot reported that the magnetos had been in the off position and only the master switch was on. An FAA inspector examined the ignition system and found no evidence of mechanical malfunction. He also reported that the aircraft had two 100-hour inspections within the past 2 months, at which time the ignition system was checked with no abnormalities noted.

Probable Cause: The failure of the pilot to secure the ignition system and magnetos in the off position before asking the ground crewman to rotate the propeller.
