## Summary

We propose to supersede Airworthiness Directive (AD) 2015-23- 13, for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2015-23-13 currently requires modification of the pin programming of the flight warning computer (FWC) to activate the stop rudder input warning (SRIW) logic; and an inspection to determine the part numbers of the FWC and the flight augmentation computer (FAC), and replacement of the FWC and FAC if necessary. Since we issued AD 2015-23-13, we have determined that, for certain airplanes, additional modification instructions must be accomplished to allow installation of the minimum FWC and FAC configuration compatible with SRIW activation. This proposed AD would, for certain airplanes, also require accomplishment of additional modification instructions to install the minimum FWC and FAC configuration compatible with SRIW activation. We are proposing this AD to address the unsafe condition on these products.
