Airworthiness Directives; Gulfstream Aerospace LP Model Galaxy 
and Gulfstream 200 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 Model Galaxy and Gulfstream 200 airplanes. The proposed AD 
would have required repetitive inspections for damage of the flexible 
supply lines of the pilot and copilot oxygen mask boxes, and eventual 
replacement of the lines with new rigid tubes. Since the proposed AD 
was issued, we have received new data that 100% of the affected 
worldwide fleet has accomplished the hardware replacement in accordance 
with the service bulletin specified in the proposed AD. Accordingly, 
the proposed AD is withdrawn.

ADDRESSES: You can examine the AD docket on the Internet at http://dms.dot.gov, or in person at the Docket Management Facility office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the U.S. 
Department of Transportation, 400 Seventh Street SW., room PL-401, 
Washington, DC. This docket number is FAA-2004-19564; the directorate 
identifier for this docket is 2004-NM-103-AD.

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 Model Galaxy and Gulfstream 200 
airplanes. That NPRM was published in the Federal Register on November 
10, 2004 (69 FR 65105). The NPRM would have required repetitive 
inspections for damage of the flexible supply lines of the pilot and 
copilot oxygen mask boxes, and eventual replacement of the lines with 
new rigid tubes. The NPRM was prompted by a report of an oxygen leak in 
the cockpit mask box. The proposed actions were intended to prevent a 
broken oxygen supply line, which could result in oxygen being 
unavailable to the flightcrew.

Actions Since NPRM Was Issued

    Since we issued the NPRM, we have received confirmation from the 
manufacturer that 100% of the affected worldwide fleet has accomplished 
the hardware replacement in accordance with the service bulletin 
specified in the NPRM.

FAA's Conclusions

    Upon further consideration, we have determined that the maintenance 
actions have adequately addressed the safety concerns and that an AD is 
not required. 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-2004-19564, 
Directorate Identifier 2004-NM-103-AD, which was published in the 
Federal Register on November 10, 2004 (69 FR 65105).

    Issued in Renton, Washington, on March 7, 2005.

Manager, Transport Airplane Directorate, Aircraft Certification
