Ben Sandilands sums up this incident perfectly;
The Pel-Air incident ought to be a lightning rod for immediate action by federal parliament, with some remedial action in terms of transparency as a legislative priority followed by an appropriate committee hearing and ministerial intervention at the top of CASA, the air safety regulator, and the ATSB, the air safety investigator.
CASA and the ATSB ought not be responding to this report, but to a parliament seized with the seriousness of these failings in the public administration of air safety.
Pel-Air and CASA damned by safety audit documents | Plane Talking
