Stiff elevators during cruise, 8 nm south-east of Liverpool Airport, 9 December 2022

皇冠体育app aircraft鈥檚 elevator controls became stiff as the aircraft approached its cruising altitude, resulting in an uncommanded descent of 800 ft. 皇冠体育app flight crew successfully applied the Quick Reference Handbook (QRH) procedure for jammed elevator controls and full elevator control was regained during the descent. 皇冠体育app investigation was unable to identify the cause of the stiff elevators and a detailed examination of the aircraft did not reveal any technical faults, so the likely cause was transitory.
