Background
The flight was a personal cross-country journey for the pilot and his wife, with their destination being North Carolina to visit relatives. The departure airport was Craig-Moffet Airport. According to witnesses, the aircraft's engine operated poorly from the start of the takeoff roll.
Observations
Witnesses at the airport reported that the engine ran roughly throughout the takeoff. The aircraft required nearly the entire runway to lift off, indicating a lack of power or efficiency. These observations were made by several independent witnesses.
Accident
After finally becoming airborne, the aircraft failed to gain altitude and instead descended, striking trees before crashing into an irrigation ditch. The aircraft came to rest in the ditch. The pilot and his wife were the only occupants on board.
Examination
A post-accident inspection revealed that the engine was worn and the spark plugs were deficient. The inspection also noted the condition of the engine as a whole.
