aterpster,
You would think it was CAT D but it is not. It is classed as a CAT C aeroplane.
This accident occurred on the morning of MAR 4th, so a NOTAM effective from the 9th APR has nil bearing on the actual accident flight.
A possible cause for the issuance of the NOTAM may well be due to landing threshold pavement damage due to the "hard landing" of the accident aircraft.
