Investigation Summary
The aircraft, a 14-year-old ATR 72-500, was navigating a region with a SIGMET warning for severe icing. Flight data indicates that the Aircraft Performance Monitoring (APM) system likely triggered alerts as ice accumulated on the airframe. The ATR 72 is known to be sensitive to icing, which can significantly alter the wing's airfoil and lead to an uncommanded roll or stall if not properly managed. In this event, the aircraft lost lift and entered a 'flat spin'—a stable but unrecoverable rotation where the wings are completely stalled and the aircraft descends vertically with little forward airspeed.
Final Conclusions
While the final report is pending, CENIPA's preliminary data confirms the presence of severe icing and de-icing system activation. The investigation is currently focusing on the crew's response to the icing alerts, the mechanical state of the de-icing boots, and why the aircraft was not moved to a different altitude despite the known meteorological hazards.

Systems & Failure Modes
De-icing Boots
Pneumatic rubber bladders on the leading edges of the wings that inflate to crack and shed ice buildup.
APM (Aircraft Performance Monitoring)
A system that monitors drag and speed to alert pilots if ice accumulation is degrading flight performance.
Stall Protection System
Includes a stick shaker and pusher designed to prevent the aircraft from entering a stall.
Interesting Facts
- 01The crash is the deadliest aviation accident in Brazil since 2007.
- 02A SIGMET (Significant Meteorological Information) for severe icing was active in the area.
- 03The aircraft was in a flat spin, a rare and often unrecoverable flight state for commercial turboprops.
- 04The Flight Data Recorder (FDR) was operating under a temporary 18-month waiver from ANAC, missing some non-essential parameters.
- 05All 62 occupants, including 58 passengers and 4 crew members, perished.
Safety Actions & Advisories
ANAC Operational Suspension
Following the accident and subsequent inspections, the Brazilian aviation agency ANAC suspended Voepass's Air Operator Certificate due to safety concerns.
Icing Awareness Training
CENIPA and ATR issued reminders to operators regarding the critical nature of icing procedures and the importance of maintaining speed in icing conditions.
