## Summary

The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation (Gulfstream) Models G-IV and GIV-X airplanes. The NPRM was prompted by reports of disbonding and surface cracking of the composite aft pressure bulkhead. The NPRM proposed to require inspecting the forward and aft surfaces of the pressure bulkhead composite panels for damage and repairing any damage found. Since issuance of the NPRM, the FAA has determined that there is not an unsafe condition. Accordingly, the NPRM is withdrawn.
