A detailed National Transportation Safety Board report has pinpointed the sequence of events that brought down a Cessna 150F near Rigby-Jefferson County Airport in September 2025, with investigators determining that severe performance problems immediately after takeoff left the aircraft unable to regain sufficient height to avoid obstacles on the ground.
The crash occurred on September 17, 2025, when a 21-year-old student pilot from Tetonia and a 38-year-old instructor pilot from Victor were conducting what began as a routine introductory instructional flight. Their initial training sortie had lasted 48 minutes and concluded successfully, according to the NTSB findings. The pair then prepared for a final departure around 11:30 a.m.
Immediately after becoming airborne, the aircraft encountered critical performance degradation. The Cessna struggled to gain altitude, forcing the instructor to assume full control of the aircraft. With the plane unable to climb sufficiently and lacking the height necessary to execute a safe return to the runway, the instructor faced limited options as the aircraft descended toward populated and developed areas surrounding the airport.
Sequence of Impact
As the aircraft continued to lose altitude, its left main landing gear clipped a power line. That contact appeared to trigger a cascade of structural failure. The plane entered a severe 90-degree nose-dive and spin at approximately 80 feet above ground—a height that left almost no margin for recovery. The instructor applied rudder pressure in an attempt to counteract the spin, but the damage was already substantial.
The force of the maneuver tore the left main landing gear completely free from the fuselage. The left wing then struck the Intermountain Auto Wrecking building before the aircraft rolled to the right, with the right wing, engine, and forward fuselage slamming into the ground.
Despite the violent impact and destruction of the aircraft, both occupants survived. Witnesses at the scene assisted the two men from the wreckage, and both were treated for minor injuries. After exiting the damaged plane, the crew completed an emergency engine-securing checklist as a precautionary measure.
Community Impact and Recovery
The crash caused collateral damage beyond the aircraft itself. When the left landing gear struck the power line, the contact severed electrical service to more than 2,700 Rocky Mountain Power customers in the surrounding area. The outage persisted for several hours while utility crews assessed damage and restored lines to service.
The NTSB report does not specify the underlying cause of the aircraft’s immediate performance loss after takeoff, focusing instead on documenting the mechanical and structural failures that occurred during the descent and impact sequence. The investigation examined factors including weather conditions, aircraft maintenance records, and pilot experience, though specific conclusions about root causation remain confined to the official NTSB documentation.
What Comes Next
The release of the NTSB report closes the investigative phase of the incident. The findings are now available to the aviation community, flight schools, and aircraft manufacturers for safety analysis. Rigby-Jefferson County Airport and surrounding emergency services have continued normal operations in the months since the September 2025 crash. The facility serves as a training base for multiple flight instruction programs across southeastern Idaho.
Both pilots have recovered from their injuries. The incident underscores the critical importance of aircraft performance margins during takeoff and the rapid decision-making required when an aircraft fails to perform as expected immediately after leaving the ground.
