Airworthiness Directives; Gulfstream Model G-1159 (G-II), G-1159A 
(G-III), and G-1159B (G-IIB) Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Proposed rule; withdrawal.

-----------------------------------------------------------------------

SUMMARY: This action withdraws a notice of proposed rulemaking (NPRM) 
that proposed a new airworthiness directive (AD), applicable to all 
Gulfstream Model G-1159 (G-II), G-1159A (G-III), and G-1159B (G-IIB) 
series airplanes. That action would have required inspections to detect 
cracking and/or corrosion at various locations of the wings, and 
modification of cracked and/or corroded parts. Since the issuance of 
the NPRM, the Federal Aviation Administration (FAA) has received new 
data verifying that all affected airplanes have complied with the 
requirements proposed by that NPRM. Accordingly, the proposed rule is 
withdrawn.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to add a new airworthiness 
directive (AD), applicable to all Gulfstream Model G-

[[Page 37315]]

1159 (G-II), G-1159A (G-III), and G-1159B (G-IIB) series airplanes, was 
published in the Federal Register as a Notice of Proposed Rulemaking 
(NPRM) on May 8, 1996 (61 FR 20764). The proposed rule would have 
required inspections to detect cracking and/or corrosion at various 
locations of the wings, and modification of cracked and/or corroded 
parts. That action was prompted by a report indicating that cracks, 
caused by stress corrosion, were found at various locations at buttock 
line (BL) 0 to BL 19 of the lower wing plank. The proposed actions were 
intended to prevent such stress corrosion, which could result in 
structural failure of the wing under certain load conditions.

Actions that Occurred Since the NPRM Was Issued

    Since the issuance of that NPRM, Gulfstream has provided evidence 
to the FAA that the actions proposed in the NPRM have been accomplished 
on all affected airplanes. (Evidence was provided to the FAA in 
Gulfstream's letter of May 30, 2000, which is filed in the Rules 
Docket.)

FAA's Conclusions

    Upon further consideration, the FAA has determined that requiring 
the modification specified in the NPRM (Rules Docket 96-NM-90-AD) is 
unnecessary since the unsafe condition no longer exists. Accordingly, 
the proposed rule is hereby withdrawn.
    Withdrawal of this notice of proposed rulemaking constitutes only 
such action, and does not preclude the agency from issuing another 
notice in the future, nor does it commit the agency to any course of 
action in the future.

Regulatory Impact

    Since this action only withdraws a notice of proposed rulemaking, 
it is neither a proposed nor a final rule and therefore is not covered 
under Executive Order 12866, the Regulatory Flexibility Act, or DOT 
Regulatory Policies and Procedures (44 FR 11034, February 26, 1979).

List of Subjects in 14 CFR Part 39

The Withdrawal

    Accordingly, the notice of proposed rulemaking, Docket 96-NM-90-AD, 
published in the Federal Register on May 8, 1996 (61 FR 20764), is 
withdrawn.

    Issued in Renton, Washington, on June 7, 2000.

Acting Manager, Transport Airplane Directorate, Aircraft Certification 
Service.
