Plain English Summary

4/10 complexity

This AD applies to Australian‑registered CASA‑212 aircraft and requires immediate compliance with Service Bulletin S.B. 212‑27‑25 to modify the rudder hinge fittings. It cancels the prior directive, declares the current modification state incompatible with S.B. 212‑55‑07R3, and cross‑references AD/CASA/8. Operators/owners must carry out the modification; the AD sets the requirement but does not specify costs, timing details, or technical steps (those are in the referenced service bulletins).
