What happened
On July 1, 2011, an EMB-810D, registration PP-EJB, was operating a flight sequence in the state of Pará, Brazil. After an initial leg from Tiriós to Cuxaré, the aircraft departed Cuxaré at approximately 19:00 UTC, bound for the Bona village. Approximately 100 km into the flight, while traveling south, the aircraft collided with trees and the ground in a dense jungle area near Óbidos.
The impact resulted in four fatalities, including the pilot and three passengers. The aircraft was completely destroyed upon impact. Evidence from the wreckage distribution indicated that the engines were producing power at the time of the collision.
The investigation
CENIPA's investigation focused on the meteorological conditions and the pilot's decision-making process. Investigators identified that the region was experiencing significant atmospheric instability, with convective clouds and thunderstorm cells developing throughout the afternoon. Satellite imagery confirmed a large weather system was active in the area, characterized by heavy precipitation and potential downdrafts.
The investigation also examined the operational environment of the operator, W&J Táxi-Aéreo Ltda. Findings revealed that the company permitted landings at unregistered airstrips and utilized improper refueling methods. Investigators also looked into the pilot's psychological state, noting that personal family matters and a high level of motivation to complete the mission and return to Santarém may have influenced the flight's outcome.
Findings
- Adverse meteorological conditions were present, with heavy cloud cover and instability likely contributing to the accident.
- The pilot may have attempted to maintain visual flight conditions by descending into terrain, leading to the collision with a hill.
- Improper decision-making was a significant factor, as the pilot likely failed to adequately analyze the risks of proceeding in deteriorating weather.
- The pilot's high motivation to finish the task and return home may have compromised his ability to assess the hazards of the weather system.
- A lack of a robust safety culture within the operator's organization was noted, specifically regarding the lack of oversight for flight planning and the use of unregistered landing sites.
