One of the issues lurking in the background of this sad accident is common to all manufacturers, namely that there has been a race to the bottom on TR and differences training requirements. Everything has been reduced to the absolute minimum because that is what the customer/operator wants ('best price'), and it has been allowed by the regulators. Compared with the unit price for a new airframe, the training cost is small but it is an easy target when it comes to shaving a few $$ off the bottom line. Time for a re-think?
