What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
During a ferry flight instructor pilot failed to properly calculated fuel burn resulting in the aircraft running out of fuel short of their final destination. When the aircraft's engine began to sputter and lose power the instructor pilot conducted an offsite landing in a field with no injuries and no damage to aircraft. The pic/instructor contacted a friend who is an A&P and asked if they could refuel the aircraft with automotive gasoline. They agreed that the aircraft could be refueled using automotive gas and the aircraft was refueled. However, the aircraft did not have an STC for auto gas. He stated he completed a runup and attempt to takeoff. The aircraft failed to become airborne, and the takeoff was aborted. He repositioned the aircraft to a road on another part of the field and attempted a second takeoff. Again, the aircraft failed to become airborne. The take off was aborted, however, the aircraft rolled down a hill where the right-wing tip and propellor impacted the ground. On both take-off attempts he had a passenger on the aircraft.
