- Date: August 1, 2001
- Aircraft: Mitsubishi MU-2 Marquise
- Location: Hilton Head, South Carolina, United States
- Fatalities: 1
- Phase of flight: Approach and landing
- Cause: Improper maintenance and inadequate inspection of the flap torque tube joints, which allowed the right flap coupler to detach and produce asymmetrical flap lift and an uncontrolled roll.
On approach to Hilton Head the Bankair Marquise rolled sharply right and descended into trees before hitting the ground and burning. The right flap torque tube had disconnected, leaving the flaps asymmetrical. Investigators found cotter pins incorrectly installed after maintenance, and the pilot was killed.
