THE PILOT WAS BLOWING CHERRY TREES DRY WITH ROTOR DOWNWASH FROM AN ALTITUDE ABOUT 5 TO 8 FEET ABOVE THE TREETOPS. DURING THE FLIGHT, ONE SET OF POINTS IN THE ENGINE'S DUAL-POINT MAGNETO BECAME LOOSE AND STOPPED OPERATING. THE ENGINE SUFFERED A PARTIAL LOSS OF POWER DUE TO THE RESULTING LOSS OF IGNITION FROM THIS SET OF POINTS. DUE TO THE LOW ALTITUDE FLIGHT AND MANEUVERING REQUIRED FOR THE OPERATION, SUFFICIENT ALTITUDE WAS NOT AVAILABLE TO AVOID A FORCED LANDING IN THE CHERRY ORCHARD.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
