Aviation Accident Summary ATL95LA143

KILL DEVIL HILL, NC, USA

Aircraft #1

N5415J

CESSNA 172N

Analysis

THE PILOT HAD RENTED THE AIRPLANE FOR THE PERSONAL FLIGHT TO KITTY HAWK. AFTER LANDING, THE MASTER SWITCH WAS INADVERTENTLY LEFT IN THE 'ON' POSITION, WHILE THE PILOT AND HIS PASSENGERS WERE SIGHTSEEING. WHEN THEY RETURNED TO THE AIRPLANE, THE BATTERY WAS TOO WEAK TO START THE ENGINE. A LOCAL AIR TOUR PILOT AGREED TO ASSIST WITH HAND STARTING THE ENGINE, SINCE THERE WERE NO SERVICES AT THE AIRSTRIP. ACCORDING TO THE PILOT, HE WAS INSTRUCTED TO PLACE THE MASTER SWITCH IN THE 'ON' POSITION. SEVERAL ATTEMPTS TO START THE ENGINE WERE UNSUCCESSFUL. THE ASSISTING PILOT CAME TO THE COCKPIT DOOR TO VERIFY THAT THE MASTER SWITCH WAS IN THE 'ON' POSITION. THE PILOT ASKED WHERE THE IGNITION SWITCH SHOULD BE, AND WAS TOLD IT SHOULD BE IN THE 'START' POSITION. WHEN THE PROPELLER WAS NEXT MOVED, THE ENGINE STARTED, AND THE PROPELLER STRUCK THE ASSISTING PILOT, BREAKING HIS HAND.

Factual Information

On July 25, 1995, about 1400 eastern daylight time, a bystander, who was a pilot, and who was assisting in starting the airplane, was struck by the propeller of a Cessna 172N, N2415J. The flight was originating at First Flight Airport, Kitty Hawk, North Carolina. The bystander was seriously injured. There were no injuries to the private pilot, nor his two passengers, and the airplane was not damaged. The airplane was operated by Carolina Air Services, Inc., under 14 CFR Part 91, and visual flight rules. Visual meteorological conditions prevailed. A flight plan was not filed for the personal flight. The pilot had rented the airplane and flown from New Bern, North Carolina, to Kitty Hawk. While sightseeing, the master switch was inadvertently left in the "on" position. When the pilot returned, the battery had insufficient output voltage to start the airplane. A local pilot agreed to help start the airplane by hand. According to the pilot of the accident flight, the bystander told him to place the master switch in the "on" or "off" position, when instructed, and call out its position in reply. The initial attempts to start the airplane were unsuccessful. The assisting pilot stepped to the cockpit door to verify that the master switch was in the "on" position. The accident pilot asked where the ignition switch should be, and was told to place the ignition switch in the "start" position, as normal. When released, the switch was in the "both" position. As the bystander moved the propeller again, the engine fired. His hand was struck and broken by the propeller.

Probable Cause and Findings

The attempt by the pilots to perform the unfamiliar procedure of starting the airplane's engine by hand.
