The left main gear wheels separated after touchdown short of the runway. Contributing factors (translated from Portuguese) – Application of the commands – contributed. There was no effective action on the aircraft controls during the final approach to avoid abrupt ground contact before the start of the runway. – Adverse weather conditions – undetermined. It is possible that the aircraft was under the effect of the phenomenon known as Windshear, which caused the destabilization of the landing approach and the consequent impact with the ground before the runway. – Pilot judgement – contributed. The risks of a possible wind shear during the final approach to landing were not adequately considered. The decision to proceed to the landing, to the detriment of the alternative recommended by experts to perform a missed approach, proved decisive for the development of the accident.
