Synopsis
On March 29, 1996, a pilot and a flight instructor (CFI) conducted the first flight of an aircraft following its annual inspection. The aircraft had been stored outdoors since early 1989 before being purchased by the pilot. Shortly after takeoff, one engine began to run rough and lose power. The pilots turned back toward the airport, but before reaching the runway, the second engine ceased operating. On short final approach, the first engine, which had been running rough, also stopped. With insufficient altitude to reach the runway, the aircraft touched down short of the runway and sustained damage.
Inspection History
An annual inspection had been completed on March 28, 1996. Maintenance records indicated that new fuel lines were installed during the inspection, and both gascolators were cleaned and inspected. The recorded entry for the annual inspection noted, "All fuel and oil lines checked, all accessories inspected."
Postaccident Examination
Following the accident, an inspection of the aircraft revealed the following:
- Both gascolators contained rust-colored deposits, and the left gascolator bowl had water present. Both gascolator screens appeared dark with water corrosion.
- Dark colored contamination was found in the left and right fuel servo inlet screens.
- The shaft of the left engine's left magneto exhibited a wobble, and its drive coupling was cracked.
- The right engine's left magneto did not produce a spark when tested.
- Contamination, including oil and corrosion, was found inside the right engine's right magneto housing.
