What happened
On a dark and foggy night, the pilot departed to reposition the unspecified aircraft for scheduled avionics work. The aircraft had recently undergone the installation of new fuel flow transducers. According to the pilot, the preflight inspection and engine run-ups were completed without issue.
During the climb, approximately 150 feet above the ground, the left engine lost power. Shortly after this initial failure, the right engine also lost power. The pilot attempted a forced landing, during which the aircraft struck trees. The subsequent impact resulted in the destruction of the aircraft due to a postimpact fire.
The investigation
Postaccident inspections of the engines and the newly installed fuel flow transducers showed no evidence of mechanical malfunction prior to the accident. To further evaluate the power loss, the engines were moved to a test facility. During subsequent test runs, both engines operated satisfactorily.
