Accident: Ercoupe 415-C

A malfunction of the fuel transfer system for reasons that could not be determined based on the available information, a stuck float in the header tank sight gauge that resulted in an inaccurate fuel quantity indication, and the pilot’s inadequate monitoring of the wing tank fuel quantity during the flight, which resulted in a loss of engine power due to fuel starvation when the header tank became depleted of fuel.
