Primary finding
Probable cause
The pilot's inadequate fuel planning and improper in-flight decision-making, which resulted in a total loss of engine power due to fuel exhaustion.
Investigator assessment
Analysis narrative
The pilot reported that while returning from a 5-hour aerial survey flight, she noticed about a quarter tank of fuel indicated on each fuel gauge and continued the flight toward the destination airport. While on the approach, the pilot noticed that both engines sputtered and both fuel gauges indicated empty. The pilot conducted a forced landing to a highway median, and the airplane impacted guardrails. Both wings, the empennage, and fuselage sustained substantial damage. Postaccident examination of the airplane revealed that the fuel tanks contained no usable fuel.
