Unsafe Condition

Failure of the upper support lugs, which prevents the centering cams from keeping the nose landing gear (NLG) in the center position when the shock absorber is extended and the steering system is depressurized, combined with a failure of the braking and steering control unit (BSCU), which prevents the normal steering system from re-centering the NLG.

AI-generated summary from the source AD text. Verify against the official source before acting.

Required Actions

Inspect to determine whether certain BSCUs are installed or have ever been installed. For airplanes with such BSCUs, check the NLG strut inflation pressure and adjust if necessary; perform a boroscope inspection of the NLG upper support (backplate) to detect ruptured anti-rotation lugs and take corrective action if necessary. For some airplanes, revise the aircraft flight manual to incorporate an operating procedure to recover normal steering in the event of a steering failure.
