The investigation was conducted by
CENIPA, on preliminary data, the plane with registration number PT-ONJ was up to date and with active registration. The plane and pilot were authorized to perform
air taxi service and both pilot and copilot were considered experienced and the flying conditions at the time of the crash were favorable. At the scene there was a strong smell of fuel but no fire. On 5 November, the
Companhia Energética de Minas Gerais issued a note stating that the aircraft had hit power lines in Caratinga, in the
Vale do Rio Doce. Preliminary information from pilots who were flying over the area at the same time of the crash corroborate the statement, having witnessed the moment when the twin-engine turboprop aircraft hit the electric cables. On 15 May, 2023,
Cenipa released the final report regarding the cause of the accident. It found that the pilots had initiated the approach too early and at a significantly greater distance than expected for a
Category B aircraft and with a very low separation from the ground. The investigation could not conclusively determine why but four possible contributing factors were identified: • The pilots inadequately assessed the aircraft's operating parameters since the downwind leg was elongated by a significantly greater distance than that expected for a "Category B" aircraft in landing procedures under
VFR. • It was suspected that during the approach, the flight crew had their attention focused on the runway at the expense of maintaining a proper separation from terrain. • It was also suspected that the pilot-in-command may have been influenced by his ten-year experience of flying long final approaches, making the actions automated in relation to the profile performed in the accident. • And finally, though it couldn't be determined, it is possible that the crew didn't use the available aeronautical charts, which could've further decreased the crew's already low situational awareness regarding the presence of power lines around the airport. == See also ==
