NO. ANDOVER, MA, USA

Aircraft #1

N9975Q

PIPER PA-18-135

Analysis

DURING THE FINAL APPROACH, THE PILOT OF N9975Q WAS INSTRUCTED BY THE TOWER TO MAKE A GO-AROUND, BECAUSE ANOTHER AIRPLANE HAD FAILED TO RESPOND TO TOWER INSTRUCTIONS. THE PILOT SAID, 'I APPLIED FULL THROTTLE AND CLOSED THE CARB HEAT THEN THE ENGINE SPUTTERED AND QUIT.' WHEN THE PILOT ATTEMPTED TO MAKE AN EMERGENCY LANDING, THE OTHER AIRPLANE WAS ON THE RUNWAY, STILL IGNORING TOWER INSTRUCTIONS. THE PILOT OF N9975Q BANKED LEFT AND LANDED IN SNOW COVERED GRASS, AND THE AIRPLANE NOSED OVER. NO MECHANICAL DISCREPANCIES WERE FOUND DURING THE POST-ACCIDENT INVESTIGATION OF THE ENGINE; HOWEVER, THE MAGNETO SWITCH WAS SET IN THE OFF POSITION.

Probable Cause and Findings

THE PILOT INADVERTENTLY TURNED OFF THE MAGNETO SWITCH DURING A GO-AROUND, RESULTING IN A LOSS OF POWER. ALSO CAUSAL TO THE ACCIDENT WAS THE FAILURE OF THE PILOT OF A SECOND AIRPLANE TO RESPOND TO THE TOWER CONTROLLER'S INSTRUCTIONS. A FACTOR RELATED TO THE ACCIDENT WAS THE PILOT'S LIMITED FLIGHT EXPERIENCE IN THIS MODEL AIRPLANE.
