Aircraft Accident/Incident Report
Pacoima, California 91331

NTSB Narrative Summary Released at Completion of Accident
The airplane nosed over during an off airport forced landing following a loss of engine power in the takeoff initial climb. The student and certified flight instructor (CFI) departed on runway 14 for pattern work, and made a full stop landing. They taxied back, and took off again. About 150 feet above ground level (agl), the engine lost a little power. They turned back toward the airport. During the turn the engine lost more power, and the airplane could not maintain altitude. The CFI took control, and elected to land in a dry pond. The airplane touched down good, but the nose wheel dug into the soft dirt, and the airplane nosed over. Examination revealed that none of the ignition leads were connected to the top spark plugs. The number 3 cylinder top plug was missing with oil on the upper cowling above the hole, and the top spark plugs for the remaining cylinders were loose, with most only engaged by one or two threads. Two hours prior to the accident flight, a mechanic performed work, including installation of a new left magneto and new spark plugs.
NTSB Probable Cause Narrative
a loss of engine power due to the failure of maintenance personnel to tighten the top spark plugs, and install the leads for the ignition harness to the top spark plugs.
