Report on aviation accident en-route Stavanger and Oslo in Norway on 10. May 2022 with Boeing 737-883, LN-RRH operated by SAS
Aviation report 2023/05
During the descent towards Gardermoen, at FL210 and in clear air, the aircraft suddenly and unexpectedly entered turbulence with a strength that the flight crew could not have predicted. Serious injuries occurred. The strong turbulence may have been induced by a combination of two turbulence phenomena, CAT (Clear Air Turbulence) and turbulence in connection with CB clouds.
Three cabin crew were injured. Two suffered minor fractures. The third of the cabin crew was seriously injured and suffered, among other things, extensive fractures.
A passenger who had not fastened his seat belt while seated hit his head on the hat rack when he was thrown into the air. The NSIA would emphasise that it is strongly recommended to have the seat belt fastened at any time while seated.
This report is in Norwegian only.
No safety recommendation is issued in connection with this investigation.
