## Summary

We propose to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation Models G-IV and GIV-X airplanes. This proposed AD was prompted by the potential for fatigue cracks developing in the main landing gear actuator attachment fitting that had a certain repair incorporated. This proposed AD would require incorporating new revisions into the Instructions for Continued Airworthiness of the Limitations section of the FAA-approved maintenance program (e.g., maintenance manual) that establish an inspection cycle for the repaired MLG side brace actuator fittings. We are proposing this AD to address the unsafe condition on these products.
