## 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) Model GVII-G500 airplanes. The NPRM was prompted by a report of a fuel quantity disparity between the overhead panel touch screens and the touch screen controllers. The NPRM proposed to require incorporating operating limitations into the airplane flight manual (AFM) until the fuel quantity management system (FQMS) software is updated. Since issuance of the NPRM, the FAA has determined that there is not an unsafe condition because all affected airplanes have updated software. Accordingly, the NPRM is withdrawn.
