Managers Perspective (and Prince)-
How can the MR not be in effect for the flight? You can't SFP a pax flight (if you can, let me know who your contact is so I can start using them
), so normal MR CAR/CASR procedures would have been in place.
Anyway, any crew or engineer (or maintenance controllers - or the operations guys looking at the flight data downloads, etc, etc) can cease the MR under CAR47. Nothing unique right there and I don't see any smoking gun by quoting it.
You probably should be quoting SDRs.
Who does the ATR engineering stuff? Toll?
