On 27 October 2018, a single pilot Leonardo AW169 helicopter lifted off from within the Leicester City football stadium but after an almost immediate failure of the tail rotor control system, control was lost and ground impact and a post crash fire resulted in fatal injuries to all five occupants. Seizure of the tail rotor duplex bearing was found to have initiated failures which culminated in the unrecoverable loss of control of the tail rotor blade pitch angle. This failure was a direct consequence of gross failures in risk assessment at the aircraft manufacturer and an inadequate type certification process.
