Voepass ATR‑72 crash investigation finds ice, de‑icing failures and regulatory lapses
On 9 August 2024 flight 2283 operated by Voepass departed Cascavel (PR) for Guarulhos (SP) and crashed in Vinhedo, São Paulo, killing all 62 people on board. The final report released by Brazil’s aviation accident agency Cenipa concluded that the aircraft should not have taken off because the airframe de‑icing system was inoperable and severe ice was forecast at cruising altitude. The crew ignored multiple visual and aural alerts, failed to follow prescribed anti‑icing procedures, and the copilot’s control inputs conflicted with the aircraft’s automatic stall‑recovery system, worsening loss of control.
Cenipa identified 19 contributing factors, including repeated de‑icing failures on prior flights that were not logged, a company culture of normalising deviations, inadequate maintenance practices such as swapping faulty components between aircraft, and insufficient oversight by the National Civil Aviation Agency (Anac). The report recommends corrective actions for Voepass, the ATR manufacturer, Anac and European regulators to improve maintenance tracking, reporting of system faults and risk‑based supervision.
The investigation was illustrated by a simulation video presented by the Brazilian Air Force, emphasizing the multi‑layered technical and organisational shortcomings that led to the tragedy.
