On 27 November 2017, an Embraer EMB 550 crew ignored a pre-takeoff indication of an inoperative airframe ice protection system despite taxiing out and taking off in icing conditions. The flight proceeded normally until approach to Paris Le Bourget when the Captain was unable to flare for touchdown at the normal speed and a 4g runway impact which caused a main gear leg to pierce the wing followed. The Investigation found that the crew had failed to follow relevant normal and abnormal operating procedures and did not understand how flight envelope protection worked or why it had activated on approach.
