[Docket No. FAA-2009-1028; Directorate Identifier 2009-NM-188-AD]
RIN 2120-AA64

 
Airworthiness Directives; Gulfstream Aerospace LP (Type 
Certificate Previously Held by Israel Aircraft Industries, Ltd.) Model 
Gulfstream G150 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 Model 
Gulfstream G150 airplanes. The proposed AD would have required 
inspecting to determine the manufacturer of the baggage compartment 
rubber seals, and replacing the baggage compartment rubber seals 
manufactured by Gumiyan with seals manufactured by Rubbercraft. Since 
the proposed AD was issued, we have received new data from the 
manufacturer stating that all affected airplanes have already been 
modified as described in the proposed AD. 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is withdrawn.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 
Docket Office (telephone 800-647-5527) is the Document Management 
Facility, U.S. Department of Transportation, Docket Operations, M-30,

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 Model Gulfstream G150 airplanes. That NPRM was published 
in the Federal Register on November 5, 2009 (74 FR 57266). The NPRM 
would have required inspecting to determine the manufacturer of the 
baggage compartment rubber seals, and replacing the baggage compartment 
rubber seals manufactured by Gumiyan with seals manufactured by 
Rubbercraft. The NPRM resulted from mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country to identify and correct an unsafe condition on an aviation 
product. The MCAI described the unsafe condition as:

    IAI Company Flammability tests revealed that the baggage 
compartment rubber seals manufactured by Gumiyan are not compliant 
with FAR [Federal Aviation Regulation] 25, Appendix F, Part I 
requirements.

The proposed actions were intended to prevent potential ignition of the 
baggage compartment rubber seals, which could lead to a larger fire.

Actions Since NPRM Was Issued

    Since we issued the NPRM, Gulfstream Aerospace LP has informed the 
FAA that all Model Gulfstream G150 airplanes have been modified in 
accordance with Gulfstream Service Bulletin 150-25-055, dated October 
28, 2008 (specified as the appropriate source of service information 
for accomplishing the requirements of the proposed AD). Gulfstream 
Aerospace LP states that, consequently, all actions specified in the 
NPRM are complete.

FAA's Conclusions

    Upon further consideration, we have determined that the proposed AD 
is not necessary. Accordingly, the NPRM is withdrawn.
    Withdrawal of the NPRM 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, 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

    Air transportation, Aircraft, Aviation safety, Safety.

The Withdrawal

    Accordingly, we withdraw the NPRM, Docket No. FAA-2009-1028, 
Directorate Identifier 2009-NM-188-AD, which was published in the 
Federal Register on November 5, 2009 (74 FR 57266).

    Issued in Renton, Washington, on May 14, 2010.
