Cessna 210 N3919Y accident near San Rafael, California

Probable cause

The loss of engine power during initial climb for reasons that could not be determined because postaccident examination did not reveal any anomalies that would have precluded normal operation.

NTSB analysis

Before departure, the pilot confirmed the fuel level by measuring the quantity of each tank, which totaled 6 gallons in the left tank and 23 gallons in the right tank. The fuel selector was placed in the right tank position for takeoff. After taking off to the northeast and when about 500 feet above ground level during the initial climb, the engine experienced a total loss of power. The pilot switched on both boost pumps, moved the fuel selector back and forth between tanks several times, and attempted to restart the engine; however, the engine did not regain power. The pilot subsequently made a forced landing to a marsh. The airplane sustained substantial damage to the lower right forward area of the fuselage, which resulted in the right fuel reservoir tank being ruptured; neither fuel tank was breached.

Recovery personnel reported that they drained 1 gallon of aviation fuel from the left fuel tank and that the fuel selector switch was in the right tank position. Postaccident examination did not reveal any anomalies that would have precluded normal operation. A postaccident test run of the engine was accomplished with no anomalies noted. After the engine run was completed, the airplane's left and left fuel supply systems were examined. The examination revealed that there were no blockages or ruptures to the left fuel supply system and that the right fuel reservoir tank rupture permitted whatever fuel was present in the right fuel tank to drain from the system after the accident. The reason for the reported total loss of engine power could not be determined.
