What happened
On October 29, 2022, at approximately 17:45 UTC, a Neiva EMB 202A, registration PT-UVS, was performing an agricultural spraying mission at Fazenda Três Pinheiros in Lucas do Rio Verde, Mato Grosso. The aircraft departed from the farm's landing strip for a local flight to apply pesticides.
During the landing phase, after the aircraft made contact with the unpaved runway, the pilot experienced a momentary float. While attempting to execute a go-around, the aircraft was struck by a wind gust. This resulted in a loss of directional control on the ground, causing the aircraft to veer off the right side of the runway. The impact caused substantial damage to the aircraft, though the pilot escaped without injury.
The investigation
CENIPA investigators examined the operational environment and meteorological conditions at the time of the accident. The landing strip at Fazenda Trought Pinheiros, measuring approximately 1,240 by 15 meters, was determined to be adequate for the aircraft's performance requirements. The pilot was found to be fully qualified, with valid medical and agricultural flight certifications.
Because the farm lacked a local weather station, investigators analyzed data from nearby meteorological stations in Sorriso, São José do Rio Claro, and Sinop. Based on these records, investigators estimated that wind gusts in the area during the time of the accident ranged between 9.91 kt and 13.2 kt, with directions between 280° and 292°. Given that the runway heading was 327°, the investigation noted that the crosswind component likely approached or exceeded the aircraft's demonstrated crosswind limit of 10 kt.
Findings
- The pilot was properly qualified and experienced for the mission.
- The aircraft was airworthy, with up-to-date maintenance records and within weight and balance limits.
- The landing strip was suitable for the intended operation.
- A wind gust likely exceeded the demonstrated crosswind limit, contributing to the loss of control.
- The application of flight controls and the impact of adverse weather conditions were identified as contributing factors.
