The flight instructor planned to refuel midway through the flight but forgot to stop for fuel, despite observing that fuel quantity gage indications were low during the flight. While the airplane climbed out during a go-around, the engine lost power due to fuel exhaustion. The flight instructor made a forced landing and the airplane impacted trees. The airplane sustained substantial damage to both wings. The flight instructor reported that there were no mechanical malfunctions or failures that would have precluded normal operation. The flight instructor attributed the inflight fuel planning error to a lack of recent flight instructor experience and the distractions of a challenging training environment. ## Aircraft - Registration: [N6147T](https://openairdocs.org/aircraft/N6147T), registered now, S/N 15060847, built 1964 (OpenAirDocs) - Reported make and model: CESSNA 150E - Registry model: [Cessna 150E](https://openairdocs.org/model/cessna-150e) (registry code 2071812) (OpenAirDocs) - Registry engine: [Continental 0-200 series](https://openairdocs.org/engine/continental-0-200-series) (registry code 17020, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 15060847 - Year built: 1964 - Airframe hours: 5003 - Engines: CONT MOTOR 0-200 SERIES 100 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, November 30, 2021, 89 hours before - Departed: PRIV, Harrah, OK - Destination: PRIV, Harrah, OK - Airport: PRIV, Oklahoma Academy Airport, runway N/A, 1,400 × 100 ft, grass/turf - Equipment: Stall warning system, ADS-B ## Flight crew As NTSB recorded them.
