Probable cause
The flight instructor’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 flight instructor reported that, he planned to complete back-to-back flight lessons with two students. His students completed the preflight inspection and each tank measured about half full. The flight instructor verified that the fuel gauges indicated sufficient fuel for both lessons. During the second flight lesson with a student pilot at the controls, the airplane experienced a total loss of engine power. The flight instructor took control of the airplane and force-landed on a golf course. The airplane collided with trees during landing, resulting in substantial damage to the right wing. The flight instructor reported that the airplane ran out of fuel, and that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
