Summary
This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), applicable to all Gulfstream G-1159 (G-II), G-1159A (G-III), and G-1159B (G-IIB) series airplanes. That action would have required a one-time inspection to detect corrosion of the material layers of the lower aft fuselage skin in Fuselage Station (FS) 580 bulkhead assembly, and repair, if necessary. The proposal also would have required modification of the aft fuselage area and various follow-on actions. Since the issuance of the NPRM, the Federal Aviation Administration (FAA) has received new data from the manufacturer verifying that all airplanes have accomplished those actions. Accordingly, the proposed rule is withdrawn.
