On 6 July 2018, an ATR 72-600 followed an unstable approach at Fez with a multiple-bounce landing including a tail strike which caused rear fuselage deformation. The aircraft then continued in operation and the damage was not discovered until first flight preparations the following day. The Investigation found that the Captain supervising a trainee First Officer as handling pilot failed to intervene appropriately during the approach and thereafter had failed to act responsibly. The context for poor performance was assessed as systemic weakness in both the way the ATR fleet was being run and in regulatory oversight of the Operator.
