   This Directive mandates a wiring modification of IRS 2 and a test of General Purpose bus IRS entry.  Furthermore in order to maintain ADS parameter segregation against possible failures, the Directive also requires operators to comply with the amendments made to Chapter 5.40 of Aircraft Maintenance Manuals that contain an additional periodic functional test of the IRS GP Bus I/O.

   Dispatch conditions under MMEL in case of an IRS2 failure are modified after implementation of the wiring change.
