What happened
While operating in the traffic pattern for an approach to a seaplane base, a float-equipped airplane suffered a complete loss of engine power. The pilot attempted an emergency landing in the backyard of a private residence. During the descent, the aircraft struck trees and a railing on a residential deck, which resulted in structural damage to the left wing.
The investigation
Post-accident inspections of the fuel system revealed that approximately 18 gallons of fuel remained in the belly tank. In the right wing tank, only about one quart of fuel was found. The pilot reported that at the time of the power loss, the right wing tank was selected and believed to be approximately one-quarter full.
