A Challenger 604 corporate jet sustained damage during a crosswind landing on runway 22 at London-Stansted Airport, UK. Control was lost during an attempted landing in a strong crosswind, following an ILS approach. The left wingtip struck the runway several times and remained in contact with the ground as the aircraft departed the paved surface into the grass area at the side of the runway. The aircraft’s stick pusher also activated, resulting in a hard landing that damaged the aircraft’s nose landing gear assembly.
The flight then diverted to London-Gatwick Airport, where it landed at 00:51 UTC.

The aircraft yawed and rolled rapidly following a long float with insufficient airspeed in strong gusting wind conditions. Stick shaker activation was followed almost immediately by stick pusher activation, resulting in the aircraft landing on its nosewheel.
A crosswind exceeding the commander’s personal limit was forecast before departure. It would have been possible to delay departure or select an alternative arrival aerodrome with more favourable conditions.
The commander reflected that although there was an opportunity to discontinue the approach earlier, he had felt compelled to continue with the landing by a degree of plan continuation bias. Fatigue, commercial pressure and the nature of their interactions may have made the pilots more susceptible to this bias.
