Our friends in TLS aren't helping matters. Despite 1100+ A321s being built and another 1500+ on order, they refuse to produce a datapack for the A321 so currently all FSTDs are A320 only.
This seems very strange. Could you confirm ZFT?
From the report:
The non-discovery of the damage during the engineer's external inspection for the turn round is difficult to understand.
This is the primary function of a tail skid, to visually give a clear indication of a tail strike. They are not sturdy and therefore not designed to protect the aircraft unless the force of the strike is minimal.
