A McDonnell Douglas MD-83, registration N786TW, suffered a runway excursion following an aborted takeoff from runway 23L at Detroit-Willow Run Airport, Michigan, USA. The aircraft had been chartered by the University of Michigan Basketball team for a flight to a game in Washington, DC.
The aircraft overran the end of the runway, damaged approach lights, went through the perimeter fence and crossed Tyler Road.
It came to rest on grassy terrain, 345 meters past the end of the runway, with the rear fuselage across a ditch. The nose landing gear had collapsed.
Runway 23L is a 7543 ft long runway.

Post-accident examination by the NTSB revealed movement of the control column in the cockpit appeared normal; the control columns were free to move, and the elevator control tabs moved as commanded. However, when investigators tried to move the elevator surfaces by hand, the left elevator moved normally, but the right elevator was jammed in a trailing edge-down position (airplane nose down). Upon further inspection, the right elevator geared tab inboard pushrod linkage was found damaged which restricted movement of the right elevator surface but allowed movement of the control tab. After the damaged components were removed, the elevator could be moved by hand.
Examination of the flight data recorder data indicates that during the taxi and take-off roll, the left elevator moved normally, but the right elevator did not move. During takeoff roll, the left elevator began a large airplane nose-up movement (consistent with rotation) at an airspeed of about 152 knots and continued for five seconds to about 166 knots. There was no change in the airplane pitch attitude during this time. The airplane data then are consistent with the takeoff being rejected. The maximum recorded airspeed was about 173 knots.
Review of previous flight data showed normal movement of both the left and right elevator surfaces. The airplane flew to Ypsilanti two days before the accident.
