lideraviacao.com.br zoominfo.com/c/líder-aviação/372493800 Líder Aviação is Latin America's largest business aviation company, founded in 1958 in Belo Horizonte, Brazil, as an air taxi with a single Cessna 170. Today: ~R$1.2B revenue, 1,300+ staff, 50+ aircraft, 22 own bases; 42.5% owned by US Bristow Group, run by the founder's third generation (President: Junia Hermont). A one-stop shop: charters (first booking app in Brazil), the region's largest FBO network, aircraft sales (exclusive HondaJet dealer, 1,000+ sold), a top MRO (authorized for Bell, HondaJet, Gulfstream) and offshore helicopter ops for Petrobras since 1973 (1M+ flight hours). Key edge: safety — the only Brazilian company with IS-BAO Stage 3, plus Argus Platinum and 5× Petrobras Peotram wins. First SAF flight in Brazilian business aviation (2024), now expanding into agribusiness and electric aviation. Bottom line: a 67-year-old family giant controlling South American business aviation end-to-end.

Evidence ladder
Attacker assertion only. Establishes: claim date, group, alleged victim.
Unlocks: incident narrative, operational impact. Still no compliance clock.
Unlocks: discovery date, data types, affected count, compliance clock.
Unlocks: materiality, stated response, full audit trail. Ceiling removed.
No regulatory filing corroborates this yet — it is the attacker's own assertion. Watch this entity to be notified the moment a filing corroborates or contradicts it.
