This AD results from data showing that the magnetic variation table installed in certain Honeywell and Northrop Grumman ADIRUs is obsolete at certain airports. We are issuing this AD to prevent the airplane from departing the runway during a CAT 2 or CAT 3 automatic landing or roll-out, due to differences between actual magnetic variation and the values in the ADIRU magnetic variation tables.
