Ameristar MD83 overran runway on takeoff at Detroit on Mar 8th 2017

An Ameristar McDonnell Douglas MD-83, registration N786TW performing charter flight 7Z-9363 from Detroit Willow Run,MI to Washington Dulles,DC (USA), was accelerating for takeoff from Willow Run's 23L at about 15:40L (20:40Z) when the crew rejected takeoff at high speed but overran the end of the runway, broke through the instrument landing system and approach lighting runway 05R, the airport perimeter fence, went over a road and came to a stop about 340 meters/1120 feet past the runway end with collapsed nose gear and main gear in a ditch. There were no injuries, the aircraft sustained substantial damage.

The aircraft was carrying Michigan's Men Basketball Team.

The Basketball team reported the aircraft attempted takeoff in high winds, the takeoff was rejected, following strong braking the aircraft went beyond the runway. There were no injuries, everyone on board is safe and sound. The team is now arranging alternative travel.

The FAA reported the aircraft on departure roll went off the runway into a fence, the persons on board evacuated via slides, no injuries, the aircraft sustained substantial damage. The occurrence was rated an accident.

The NTSB dispatched investigators on site.

On Mar 11th 2017 The Aviation Herald received information, that in addition to the collapsed nose gear both main gear struts received fractures to their upper bodies and were folded back when the aircraft went over a rise before the service road inside the airport perimeter.

So they took off on 23L with a wind 260/35 gusting 50 on a 45 minute flight. i.e. at least a 30 knot headwind component. Hardly likely to be at max weight and still managed to overrun?

Have no idea about airline ops, but I must wonder why there always a ditch or a bridge at the end of the runway

Oh hell yes... seems to be a prerequisite when building an airport

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.
