Final Report

Investigation Summary

The flight departed runway 05 at Maturín Airport at 13:25 local time. The climb appeared normal until the aircraft reached approximately 5,000 feet (1,500 meters). At this point, the crew reported an emergency to the control tower, indicating a severe control problem. Witnesses on the ground reported seeing the aircraft in a steep dive before impact. The investigation focused heavily on the flight control systems, specifically the elevator assembly, as the sudden and violent nature of the loss of control suggested a mechanical failure in the pitch axis. However, the wreckage was severely fragmented, and investigators could not find conclusive evidence of a pre-impact malfunction.

Final Conclusions

The official investigation concluded that the aircraft suffered a loss of control for undetermined reasons. While a malfunction of the elevator system was considered a highly probable factor, the lack of physical evidence from the wreckage prevented a definitive finding.
