Incident Overview
A float-equipped airplane was operating in the traffic pattern for landing at a seaplane base when the engine experienced a complete loss of power. The pilot performed an emergency landing in the backyard of a private residence. During the forced landing, the aircraft struck trees and a railing on the residence's deck, resulting in structural damage to the left wing.
Pilot Report
The pilot reported that he had the right wing fuel tank selected and believed it contained approximately one-quarter of its capacity. When the engine lost power, the pilot indicated he was too low and did not have sufficient time or altitude to switch to the belly tank to restore engine power.
Postaccident Examination
After the accident, the fuel tanks were drained. The belly tank was found to contain about 18 gallons of fuel, while the right wing tank held approximately one quart.
Conclusion
This incident involved a fuel state discrepancy between the selected right wing tank and the auxiliary belly tank. The engine power loss occurred with the right wing tank nearly empty, while a substantial quantity of fuel remained in the belly tank.
