What happened
On October 9, 2015, an EMB 110 aircraft, registered as PT-GKA, departed from Vitória da Conquista, Bahia, destined for Ilhéu, Bahia. During the flight, witnesses reported hearing an explosion. The aircraft was located approximately 2 kilometers from the crash site, having struck an obstacle at an altitude of roughly 200 feet during its takeoff phase.
The impact resulted in the deaths of two occupants. The aircraft was completely destroyed by a post-impact fire.
The investigation
CENIPA investigators examined the wreckage and flight data, though the high degree of fragmentation made the analysis difficult. Technical examinations by the CTA (Institute of Technological Research) found no evidence of structural failure or manufacturing defects. Both engines were found to be operating at high power and high RPM at the moment of impact.
The investigation also reviewed the aircraft's weight and balance. At the time of the accident, the aircraft was operating with a Center of Gravity (CG) outside of the permitted limits. The cargo weight in the baggage compartment also exceeded the maximum allowable limit. Additionally, investigators noted that the servo-motor for the autopilot pitch compensator had been deactivated, a configuration that could potentially lead to sudden attitude changes if the autopilot were engaged.
Regarding the crew, the pilot was described by acquaintances as having a highly dynamic and productive personality, but also as being prone to overconfidence. The investigation noted that the pilot frequently performed low-altitude maneuvers during cargo transport missions.
Findings
- Human factors: The pilot's psychological state, characterized by overconfidence, contributed to the accident as he attempted a low-altitude pass near a residence.
- Operational factors: The pilot's decision to perform an unauthorized low-level maneuver.
- Weight and Balance: The aircraft was operating with a Center of Gravity beyond the certified limits and exceeded baggage compartment weight limits.
