Analysis

The pilot was attempting to hand prop a 260 horse power radial engine. The engine was normally started with compressed air; however, the air reservoir was empty. The ignition system used a 'shower of sparks' system. Another pilot sat in a pilot seat to hold the brakes. The engine was primed and the magneto switch turned on. The pilot pulled the propeller blade and one cylinder fired. His head was within the arc of the rotating propeller blades and he was struck by a blade.

On July 11, 1994, at 1200 eastern daylight time, the pilot was struck by the propeller while attempting to hand prop a WSK- PZL, Wilga 80, N7080B, at Harford County Airport, Churchville, Maryland. The pilot received serious injuries and the airplane was not damaged. Visual meteorological conditions prevailed and no flight plan had been filed for the flight which was operating under 14 CFR Part 91.

According to the FAA, the airplane engine was a 260 horse power radial. It was normally started with compressed air; however, the air reservoir was empty. The ignition system used a "shower of sparks" system for starting. The pilot had requested another pilot to sit in one of the pilot seats and hold the brakes. The engine was primed and the magneto switch turned on.

The accident occurred when the pilot started to pull the propeller blade through while his head was still within the arc of the rotating propeller blades. One cylinder fired, and the propeller blades rotated, and one blade struck the pilot in the head.
