What happened
An on-demand flight departed from Curitiba-Afonso Pena Airport at 08:50 local time, bound for Rio de Janeiro. The flight was operated with a crew of two pilots and four passengers. After the aircraft reached its assigned cruising altitude of 33,000 feet, the flight progressed for approximately three minutes before the stick puller mechanism was triggered.
Following this activation, the twin-engine aircraft continued to climb to an altitude of 33,900 feet. Shortly thereafter, the plane entered an uncontrolled descent. The aircraft fell at a rate of 18,000 feet per minute, striking a field in a near-vertical orientation. The impact resulted in six fatalities, with no survivors among the occupants.
Findings
Investigations into the sequence of events indicate that the crew failed to reduce engine power once the aircraft had reached its assigned altitude of 33,000 feet, which preceded the subsequent uncontrolled descent.
