Probable cause

The pilot's failure to maintain altitude during cruise flight after loss of electrical power for an undetermined reason.

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.

Analysis

The private pilot was in IMC at 7,000 feet MSL and about 30 minutes into his flight when he reported a complete electrical failure. He began to accomplish lost comm procedures and attempted to maintain his last assigned heading, airspeed, and altitude. He reported no problems with his engines, pitot static system or vacuum powered flight instruments. He remembered the airplane striking tree limbs, but could remember nothing after that until the airplane had crashed onto the terrain. The elevation at the crash site was about 3,100 feet MSL. The pilot could not explain why he lost 3,900 feet of altitude prior to the crash. He did not report a lightning strike, and he was in IMC until impact. The reason for the loss off electrical power was not determined.
