What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The aircraft departed Longview, TX airport (ggg) on runway 18 on a VFR instructional flight with one flight instructor (CFI) and one student pilot on board. The student pilot was managing the flight controls. At approximately 1000 feet mean sea level (MSL), both pilots noticed a reduction of engine power of approximately 400 RPM, and began troubleshooting. When engine power could not be restored the CFI took the controls and determined the aircraft was unable to sustain flight. She made an emergency call on ggg tower frequency and was cleared to land on rwy 36. The CFI determined they would be unable to reach the airport and prepared for an off airport landing in an adjacent open grass field approximately 2 nautical miles (NM) sse of the rwy 36 threshold. The pilot made a normal approach and landing and the aircraft came to rest on a heading of 220. Both occupants were able to exit the aircraft without injury, and the CFI made a preliminary inspection of the engine. She determined there was no evidence of fire, and no obvious leaking fluids. Both fuel tanks were full of 100LL avgas.
