On 9 March 2022, a Boeing 737-800 taking off from Manchester and being used for the line training of a low experience First Officer was rotated by this trainee too rapidly and a tailstrike resulted. When asked during the climb if any abnormal noise had been heard during the takeoff, the cabin crew reported having heard “a very big bang”. The Captain then declared a PAN and the aircraft returned. The over aggressive rotation was suspected to have been a response to the trainees prior tendency to rotate too slowly and lack of training continuity was considered a potential factor.
