AAIB investigation to Boeing 737-8AS, EI-EBW
Serious injury to cabin crew, during descent to Manchester Airport, 14 January 2017.
Summary:
Whilst descending in to a high altitude jetstream, an associated rise in headwind caused the aircraft to overspeed. The commander disengaged the autopilot (AP) and used manual control inputs to stop the speed increasing, but in doing so applied a significant nose-up pitch input on the control column. The resulting manoeuvre caused two cabin crew members to fall, and one of them sustained a broken ankle. The operator has issued additional guidance to its pilots regarding overspeed recognition and recovery.
