Probable cause

The pilot in command attempted a takeoff with the fuel mixture full rich, with a high density altitude, resulting in a partial loss of engine power during initial climb.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Loss of engine power(partial) - nonmechanicalTakeoff - initial climb
Weather condition - high density altitudeFactor
Mixture - improper use ofPilot in commandCause
Forced landingDescent - emergency
On ground/water encounter with terrain/waterLanding - roll
Terrain condition - rough/uneven

Analysis

The private plt said that during initial climb, the engine seemed to lose power. He elected to make an emerency landing in a field. He said that during landing roll, the plane tipped to the left and the left wing, landing gear, and propeller were damaged. The plt reported that he had not leaned the mixture for this flight. The density altitude was computed to be 8,000 feet. The plt indicated that the plane was loaded to near maximum gross weight. A post-accident inspection showed low compression on one cylinder; 1 magneto was removed, bench tested and shown to be operational. No mechanical evidence was found to explain the reported loss of engine power.
