Confidence Rating: Accident investigation report completed and information captured
The aircraft was inbound to London Heathrow on a scheduled passenger flight from Chicago (USA). During the descent, the aircraft entered an overcast cloud layer and, shortly afterwards, the overspeed warning alert sounded. The autopilot was disconnected and the speedbrakes were deployed manually to slow the aircraft. Approximately one minute later, the aircraft experienced severe turbulence that lasted less than 30 seconds. Shortly after this event, the purser contacted the flight deck crew to inform them that several flight attendants had been injured during the turbulence. One flight attendant sustained a fractured right fibula above the ankle when a passenger fell and collided with her.
