## Analysis

THE PILOT STATED THAT DURING THE TAKE OFF, THE ENGINE LOST POWER AT APPROXIMATELY 50 FEET AGL. THE PILOT ABORTED THE TAKE OFF AND DURING THE LANDING ROLL, THE AIRPLANE COLLIDED WITH A FENCE OFF THE END OF THE RUNWAY. DURING AN ENGINE INSPECTION, A CRACK WAS FOUND BETWEEN THE TOP AND BOTTOM SPARK PLUGS ON THE NUMBER FOUR CYLINDER.

## Factual narrative

On July 27, 1994, at 1150 mountain daylight time, a Piper PA-24- 250, N6824P, experienced a partial loss of engine power shortly after takeoff from Nampa, Idaho.  The pilot aborted the takeoff and the airplane collided with a fence off the end of runway 11.  Visual meteorological conditions prevailed at the time and no flight plan was filed.  The airplane was substantially damaged and the private pilot and his three passengers were not injured.  The flight was destined for Oshkosh, Wisconsin, for the personal flight.

The pilot reported that the airplane attained an altitude of 50 feet above ground level when the engine began to run rough and lose power.  The airplane was unable to maintain altitude and the pilot aborted the takeoff.  The airplane touched down off the end of the runway and collided with a fence before coming to a stop.

During an engine inspection, a crack was found between the top and bottom spark plugs on the number four cylinder.
