| Occurrence Date/Time | 8 March 2017 |
| Aircraft Type | Boeing MD-83 |
| Flight / Operator | Ameristar aircraft (N786TW) |
| POB | 110 PAX + 6 CREWS |
| Description | calculated the V1 decision speed and rotation speed
aircraft, which reached a maximum airspeed of 173kt, did not rotate captain aborted the take-off roll
|
| Result | travelled 1,780m (5,850ft) along runway 23L before the crew applied brakes
leaving just 970m of paved surface It overran the paved surface at 100kt and struck a raised perimeter road at 40kt before coming to a halt one occupant receiving minor injuries aircraft was substantially damaged – and was subsequently written off |
| Contributory factors | Aircraft had been parked on the ramp for two days close to a large hangar
While the surface winds and gusts did not exceed aircraft design limits, computational fluid dynamics simulations showed the hangar’s presence generated localised turbulence with a vertical component that “rapidly” flipped the MD-83’s elevator surfaces up and down. This caused the elevators – which, by design, did not have gust locks – to strike their mechanical stops, sufficiently hard to jam the right-hand elevator in a full trailing-edge down position “lack of a means” for crews to detect a jammed elevator during pre-flight checks on the type. |
