- Date: July 25, 2006
- Aircraft: Spectrum FJ33
- Location: Spanish Fork, Utah, United States
- Fatalities: 2
- Phase of flight: En route
- Cause: The aft upper torque tube bell crank was installed in the wrong position during maintenance, reversing aileron control; missing maintenance documentation and no control position check during preflight allowed the error to go unnoticed.
A prototype Spectrum 33 light jet made a maintenance test flight from Spanish Fork-Springville Airport and rolled sharply right just after liftoff. The aileron controls had been connected in reverse during maintenance, so the aircraft rolled opposite to the stick input until its right wingtip struck the ground. Both commercial pilots aboard were killed.
