Yes, Brazilian aviation has been a mess lately and it is unacceptable.
Every other week there's an accident report. It can be a helicopter or a high performance aircraft or a small airplane. Last week, beside that crash in Recife, there were 3 more cases involving a helicopter and 2 SE airplanes.
Fatal accidents have occurred with pilots at controls without formal training and checks, license and medical certificate.
