CREMER VP-1
ACFT LOST ENGINE POWER ON SHORT FINAL APPROACH. ACFT STALLED AND TOUCHED DOWN HARD SHORT OF THE RUNWAY. THE ACFT THEN COLLIDED WITH THE RAISED EDGE OF THE RUNWAY COLLAPSING THE MAIN GEAR AND THEN NOSING OVER. THE PILOT ATTRIBUTED THE LOSS OF ENGINE POWER TO A WEAK MAGNETO COIL WHICH HE HAD BEEN ATTEMPTING TO REPAIR. THE WEAK COIL ALLOWED FOR A WEAK SPARK AT THE SPARK PLUGS WHICH ALLOWED THE PLUGS TO FOUL AND THE ENGINE NOT TO RESPOND QUICKLY TO POWER INCREASES.
