An airplane experienced a total electrical failure the day before an accident. After a precautionary landing, the problem was not repaired. During departure the next day, both engines lost power, leading to a forced landing in a field. The aircraft had unresolved maintenance defects.

Event Description

During a cross-country flight on the day prior to the accident, the airplane experienced a total electrical failure. The pilot made a precautionary landing at an airport, where the battery was charged. However, the electrical problem was not repaired before departing on the day of the accident.

After lift-off from the runway, the landing gear was retracted, and the pilot began a left turn. While in the turn, at about 300 to 400 feet above ground level, the left engine lost power. Subsequently, the right engine lost power. The pilot executed a forced landing to a field with brush and mesquite trees.

Pre-Accident Inspection

The airplane had been inspected six days before the accident by an FAA inspector, who issued an Aircraft Condition Notice for maintenance defects that were considered to be an imminent hazard to safety. A special flight permit was required prior to operating the aircraft if corrective action had not been taken.

Investigation

An examination of the airplane revealed that the maintenance defects were not corrected, and a special flight permit had not been obtained. The reason for the loss of engine power could not be determined.
