So Bombardier write on 4 March asking for clearance and it takes ORR five weeks to reply with virtually a standard letter. Good job it wasn't urgent then.
Eh? They've had to assess the test and technical evidence that Bombardier have submitted. I think 5 weeks turnround is pretty decent to be honest. The fact Bombardier have taken 15 months longer than expected to get to this point does not require the regulator to run about as if their pants are on fire.
