Flight Sequence
A student pilot and a certified flight instructor (CFI) departed on runway 14 for pattern work and performed a full stop landing. After taxiing back, they took off again. During the initial climb, at about 150 feet above ground level, the engine experienced a partial loss of power. The crew turned back toward the airport, but during the turn the engine lost additional power, and the airplane could not maintain altitude. The CFI took control and elected to land in a dry pond. The touchdown was satisfactory, but the nose wheel dug into soft dirt, causing the airplane to nose over.
Post-Accident Examination
Examination of the engine revealed that none of the ignition leads were connected to the top spark plugs. The top spark plug for the number 3 cylinder was missing, with oil present on the upper cowling above the hole. The top spark plugs for the remaining cylinders were loose, with most engaged by only one or two threads. Two hours prior to the accident flight, a mechanic had performed work that included installation of a new left magneto and new spark plugs.
