Airworthiness Directives; Gulfstream Aerospace LP (Type 
Certificate Previously Held by Israel Aircraft Industries, Ltd.) 
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Proposed rule; withdrawal.

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

SUMMARY: The FAA withdraws a notice of proposed rulemaking (NPRM) that 
proposed a new airworthiness directive (AD) for certain Gulfstream 
Aerospace LP (Type Certificate previously held by Israel Aircraft 
Industries, Ltd.) Model Galaxy and Gulfstream 200 airplanes. The 
proposed AD would have required determining the lengths of the wear 
indicating pins of all brake assemblies, shortening the pin if the wear 
indicating pin is too long, inspecting for normal brake wear, and 
replacing brakes with new brakes if necessary. Since the issuance of 
the NPRM, the FAA has received new data that indicates the actions 
addressing this unsafe condition have been accomplished on the 
worldwide fleet. Accordingly, the proposed AD is withdrawn.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains this AD, the regulatory evaluation, 
any comments received, and other information. The address for the

SUPPLEMENTARY INFORMATION:

Discussion

    We proposed to amend part 39 of the Federal Aviation Regulations 
(14 CFR part 39) with a notice of proposed rulemaking (NPRM) for a new 
AD for certain Gulfstream Aerospace LP (Type Certificate previously 
held by Israel Aircraft Industries, Ltd.) Model Galaxy and Gulfstream 
200 airplanes. That NPRM was published in the Federal Register on May 
31, 2012 (77 FR 32069). The NPRM would have required determining the 
lengths of the wear indicating pins of all brake assemblies, shortening 
the pin if the wear indicating pin is too long, inspecting for normal 
brake wear, and replacing brakes with new brakes if necessary. The NPRM 
resulted from reports of degraded brake performance during landing due 
to improperly-sized wear indicating pins. The proposed actions were 
intended to detect and correct improperly-sized wear indicating pins, 
which, if not corrected, could result in worn-out brake pads and 
subsequent loss of braking power, which could result in runway 
overruns.

Actions Since NPRM (77 FR 32069, May 31, 2012) Was Issued

    Since we issued the NPRM (77 FR 32069, May 31, 2012), FAA has 
received new data that indicates the unsafe condition no longer exists. 
Review of the Gulfstream Aerospace LP Model Galaxy and Gulfstream 200 
airplane service history shows that the worldwide fleet is in 
compliance with the actions specified in Gulfstream Service Bulletin 
200-32-389, Revision 1, dated October 27, 2011. Therefore, the unsafe 
condition no longer exists.

FAA's Conclusions

    Upon further consideration, we have determined that the actions 
specified in Gulfstream Service Bulletin 200-32-389, Revision 1, dated 
October 27, 2011, and the Gulfstream Aerospace LP Model Galaxy and 
Gulfstream 200 airplane service history adequately addressed the 
identified unsafe condition. Therefore, it is not necessary to issue a 
final rule. Accordingly, the NPRM (77 FR 32069, May 31, 2012) is 
withdrawn.
    Withdrawal of the NPRM (77 FR 32069, May 31, 2012) does not 
preclude

the FAA from issuing another related action or commit the FAA to any 
course of action in the future.

Regulatory Impact

    Since this action only withdraws an NPRM (77 FR 32069, May 31, 
2012), 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

reference, Safety.

The Withdrawal

    Accordingly, we withdraw the NPRM, Docket No. FAA-2012-0495, 
Directorate Identifier 2011-NM-236-AD, which was published in the 
Federal Register on May 31, 2012 (77 FR 32069).

    Issued in Renton, Washington, on October 14, 2012.
