Brazilian air force investigators concluded that the 2024 Voepass ATR 72-500 crash near Vinhedo, outside São Paulo, was caused by a combination of severe icing, repeated de-icing system failures, and pilot distractions, killing all 62 people on board. The aircraft, en route from Cascavel to Guarulhos, encountered icing at cruising altitude, leading to a loss of lift and an unrecoverable flat spin, with flight crews delaying corrective actions amid icing warnings. A culture of normalizing deviations within Voepass and preexisting mechanical issues, including de-icing faults, were highlighted as contributing factors. Investigators noted that crew members were distracted by routine radio communications and administrative tasks during critical icing stages, preventing timely maneuvers to recover control. Final findings were presented to victims’ families before public release, and authorities urged regulatory and industry action, including recommendations to EASA and ATR to review degraded performance procedures to prevent similar outcomes. The reports corroborate earlier safety assessments and have been echoed by multiple outlets detailing the cascade of icing conditions, equipment faults, and human factors that culminated in Brazil’s deadliest air crash since 2007.
