EASA 2019-0273

Applies to all Falcon 900EXs and 2000EXs with the EASy flight deck. Requires amendment of the aircraft flight manual to provide instructions to the flight crew to manually activate heating of the angle-of-attack (AoA) probes during runway line up as a new normal procedure. Prompted by reports of iced AoA probes after takeoff, with associated misleading airspeed indication and/or misleading stall warning. As per design and approved procedures, the takeoff position of the thrust levers must be reached within five seconds after starting the takeoff run. A slow or late positioning of levers into this position in certain conditions can lead to probes being heated too late during the takeoff run, which increases the risk of icing on AoA probes after takeoff.
