AAIB investigation to Airbus A321-231, G-WUKJ
High speed rejected takeoff due to unreliable speed indication, Doncaster Airport, 16 June 2020.
Summary:
During the takeoff roll, as the aircraft was approaching V1, the commander identified that the airspeed on the Primary Flight Display was reading zero and rejected the takeoff. Examination of the aircraft found insect larvae within one of the pitot probes. The aircraft had been parked for nearly 12 weeks prior to the flight. The operator has taken safety action to introduce a procedure that flushes the static and total pressure lines on any aircraft that has been parked for more than three days before it is returned to operation.
