What happened
On December 30, 1996, a Cessna 182P, registration PT-IQZ, was performing a chartered flight to transport three passengers between two uncertified, clandestine airstrips in the state of Amapá, Brazil. The flight originated from an uncertified strip located near Kilometer 14 of the BR-156 highway, destined for a farm airstrip at Cavianna.
During the takeoff roll, the pilot encountered a tailwind, as the opposite end of the runway presented a high risk of collision with natural obstacles. As the end of the runway approached, the pilot attempted to rotate the aircraft before it had reached the necessary rotation speed for adequate lift. Unable to maintain flight, the pilot attempted an emergency forced landing to the left of the intended path. During this maneuver, the aircraft struck high-voltage power lines located alongside the runway, causing the aircraft to strike the ground violently. The impact caused the engine to separate from the fuselage and the aircraft to spin nearly 180 degrees from its original trajectory. The one crew member and three passengers sustained light injuries, while the aircraft suffered severe damage.
The investigation
CENIPA's investigation focused on the operational conditions and the pilot's decision-making process. The investigation established that the aircraft was operating at an estimated weight of 3,000 lb, which exceeded the maximum allowable weight for the specific runway conditions. The investigation also noted that the operator, a taxi air company, frequently operated in uncertified strips lacking proper infrastructure. While the pilot was highly experienced with the aircraft type, the investigation found that the lack of air traffic control and infrastructure in the Amazon region had fostered a culture of complacency and disregard for basic safety margins regarding weight, balance, and performance calculations.
