Aircraft Accident/Incident Report

Rubidoux, California 92509
Sunday, July 28, 1991 12:55 PDT

NTSB Narrative Summary Released at Completion of Accident

THE PILOT WAS DEPARTING THE AIRPORT ON A LOCAL VFR MAINTENANCE TEST FLIGHT. THE AIRPORT IS SITUATED IN A HIGHLY CONGESTED AREA WITH A TREE LINE AT THE END OF THE RUNWAY. THE AIRPLANE HAD JUST BEEN RESTORED AND THIS WAS THE FIRST FLIGHT IN 19 YEARS. WITNESSES REPORTED THAT SHORTLY AFTER LIFT-OFF THE AIRPLANE'S ENGINE BEGAN TO BACKFIRE AND THEN QUIT. THE AIRPLANE ENTERED INTO A RIGHT BANK, STALLED AND CRASHED INTO A RESIDENCE'S BACKYARD. THE INVESTIGATION REVEALED THAT BOTH MAGNETO HOLD-DOWN NUTS WERE LOOSE AND THE ENGINE TIMING COULD NOT BE DETERMINED. THE LEFT MAGNETO WOULD ONLY PRODUCE SPARK IN ONE LEAD AND THE RIGHT MAGNETO WOULD NOT FIRE WHEN THEIR RESPECTIVE DRIVE WERE HAND ROTATED. THE MAGNETOS OPERATED NORMALLY WHEN TESTED WITHOUT THE ENGINE'S IGNITION HARNESS.

NTSB Probable Cause Narrative

THE MECHANIC'S IMPROPER INSTALLATION OF THE MAGNETOS AND THE PILOT'S FAILURE TO MAINTAIN FLYING SPEED. FACTORS RELATED TO THIS ACCIDENT ARE THE PILOT'S INADVERTENT STALL AND THE RESIDENTIAL AREA.
