Incident Overview
Description
The aircraft touched down on runway 07 at An polis Airport, Brazil, with a left cross wind. The pilot lost directional control of the aircraft and the An-2 suffered a runway excursion. It colliding with a protuberance on the ground, after overcoming a small ravine. There was serious damage to the aircraft, and the pilot and two passengers suffered minor injuries. The aircraft in question was seized in 1997. An aircraft was log book was not present and there had been no logging of maintenance tasks performed on the aircraft. At the time of the accident it was being ferried from Alta Floresta after small repairs were carried out there. It carried a Polish registration, which had already been cancelled in Poland. The owner was in the process of applying for a Brazilian certificate of registration. Contributing Factors a. Human Factor (1) Physiological – Undetermined It was not possible to determine the contribution of the physiological aspect because the pilot was not found and his license had expired. (2) Psychological – Contributed At the critical moment of landing, a state of indecision was triggered in the pilot regarding the procedure to be adopted (landing or going around), impairing its decision-making capacity and causing delay in decision making. b. Operational Factor (1) Flight Indiscipline – Contributed The pilot met the expired CHT and CCF. (2) Weak Application of Commands – Contributed The pilot did not act adequately on the aircraft controls in order to counteract the action of the crosswind, allowing the aircraft to stand to the right of the approach axis and touch the right side of the runway. Subsequently, he was unable to prevent the left wings from climbing, causing the lower right wing to touch the ground and exit the runway. (3) Deficient Judgement – Contributed The pilot’s decision not to go around immediately when he noticed the first signs of the aircraft’s turning tendency, forced by the wind effect and, consequently, having lost full control of the aircraft, contributed to the worsening of the subsequent facts. The pilot acted belatedly when he decided to go around. (4) Deficient Oversight – Contributed The owner of the aircraft no longer verified that the technical qualification and the Certificate of Physical Capacity of the pilot were up to date for the performance of the air activity, as well as the certificates necessary for the operation of the aircraft. It also went against what prescribes the CTA certification, which establishes two pilots as the minimum crew for the aircraft. (5) Adverse Meteorological Conditions – Contributed The left cross wind, associated with the inadequacy of the pilot’s controls to counteract it, resulted in the right wing touching the ground, with consequent loss of control of the aircraft. (6) Other Operational Aspects – Contributed The pilot failed to carry out a readaptation flight in the aircraft with a qualified instructor, being for more than three years without flying in the equipment.
Primary Cause
Pilot’s decision-making errors, specifically indecision and delayed corrective action, combined with inadequate control of the aircraft in the face of the crosswind, ultimately leading to the runway excursion and damage.Pilot’s decision-making errors, specifically indecision and delayed corrective action, combined with inadequate control of the aircraft in the face of the crosswind, ultimately leading to the runway excursion and damage.Share on:
