A flight attendant sustained serious injuries while returning to her jumpseat during descent when the aircraft encountered turbulence causing a vertical upset of 2.5 Gs.

What happened

The aircraft was in the descent phase of flight when it encountered turbulence. During this period, a flight attendant was moving from her station back to her assigned jumpseat. The sudden vertical motion associated with the turbulence resulted in a significant physical impact.

Flight data recorder analysis confirmed that the airplane experienced a vertical upset generating 2.5 Gs of force during the incident. This maneuvering load contributed directly to the circumstances leading to the injury.

Findings

The operator's report indicated that the flight attendant was unseated at the time the turbulence struck. The combination of the aircraft's vertical acceleration and the attendant's position led to a serious injury. No other details regarding specific injuries or subsequent medical treatment were provided in the source material.
