Probable cause

The pilot-in-command's failure to stand clear of the propeller as he rotated it by hand, resulting in the propeller rotating around due to engine compression, striking the pilot, causing him to lose his balance and fall to the ramp, resulting in serious injury.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Propeller - improper use ofPilot in command

Analysis

The pilot stated the starter motor would run but not turn engine. He was told by another pilot that when this happens he should exit the aircraft and reposition the propeller. He turned off the magnetos and exited the aircraft. As he turned the propeller, it rotated around due to engine compression and struck him on the forehead. He lost his balance and fell backward, at which time he struck his head on the ramp, causing a skull fracture.
