Unsafe condition

This AD was prompted by a report indicating that a new filter plate connector for the nose wheel steering (NWS) system electronic control module (ECM) does not meet certain certification requirements. The FAA is issuing this AD to address this non-compliant filter plate connector, which, if not replaced, could result in a malfunction of the NWS system causing potential uncommanded steering or lateral excursion from the runway.

Affected ADs

None.
