What happened
On June 4, 2024, at approximately 18:15 UTC, an Embraer EMB-202A, registration PT-UVX, was performing an agricultural spraying operation at Fazenda Umuarama II in Santo Antônio do Leste, Mato Grosso. The aircraft was conducting a takeoff roll from a landing strip used for agrochemical application.
During the takeoff roll, the pilot observed a dust devil (a localized whirlwind) emerging from the right side of the landing area and moving toward the left. In an attempt to avoid the phenomenon, the pilot executed a maneuver to the left. During this bank, the aircraft lost lift, causing the left wing's spray boom to strike a cotton plantation. This impact led to the landing gear contacting the ground, causing the aircraft to strike the terrain and spin counter-clockwise. The aircraft sustained substantial damage, including a broken tail cone, but the pilot emerged uninjured.
The investigation
CENIPA's investigation confirmed that the pilot was fully qualified with valid commercial licenses and medical certification. The aircraft was also in compliance with all regulatory requirements, including a valid airworthiness certificate (CVA), proper weight and balance, and up-to-date maintenance logs. The last 100-hour inspection had been completed shortly before the accident.
Meteorological analysis from nearby stations in Santo Antônio do Leste and Paranatinga indicated weather conditions were well above the minimums required for the operation. However, the investigation noted that the environmental conditions—characterized by dry, hot weather and light winds—were highly favorable for the formation of dust devils. The investigation examined the pilot's flight controls usage and the decision-making process regarding the altitude available for an evasive maneuver.
Findings
- Inappropriate use of flight controls during the takeoff roll contributed to the excessive wing tilt.
- The pilot's judgment regarding the available altitude for an evasive maneuver was a contributing factor.
- The presence of a dust devil was a confirmed event, though the exact impact of the phenomenon on the aircraft's performance could not be precisely measured.
