14 CFR Part 39

[Docket No. 2001-NM-149-AD]
RIN 2120-AA64


Airworthiness Directives; McDonnell Douglas Model MD-90-30 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 certain 
McDonnell Douglas Model MD-90-30 series airplanes. That action would 
have required an inspection of the aft galley power feeder wire 
assembly for riding, chafing, and damage located above the main cabin, 
left side, overwing ceiling panels; and follow-on actions. Since the 
issuance of that NPRM, the FAA has reviewed and approved a McDonnell 
Douglas service bulletin which describes procedures for modification of 
the installation of the aft galley power feeder wire assembly. The FAA 
has issued a new NPRM which combines the proposed requirements to 
inspect the aft galley power feeder wire assembly and perform follow-on 
actions with new proposed requirements to modify the installation of 
the galley power feeder wire assembly. Accordingly, the previous NPRM 
is being withdrawn.

FOR FURTHER INFORMATION CONTACT: George Y. Mabuni, Aerospace Engineer, 
Systems and Equipment Branch, ANM-130L, FAA, Los Angeles Aircraft 
Certification Office, 3960 Paramount Boulevard, Lakewood, California

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 certain McDonnell Douglas Model MD-90-30 
series airplanes, was published in the Federal Register as a Notice of 
Proposed Rulemaking (NPRM) on August 31, 2001 (66 FR 45948). The 
proposed rule would have required an inspection of the aft galley power 
feeder wire assembly for riding, chafing, and damage located above the 
main cabin, left side, overwing ceiling panels; and follow-on actions. 
The proposed actions were intended to prevent damage to the electrical 
wire insulation of the aft galley power feeder wires, electrical 
arcing, and potential smoke and/or fire.

Actions That Occurred Since the NPRM Was Issued

    The FAA has reviewed and approved McDonnell Douglas Alert Service 
Bulletin MD90-24A047, Revision 01, dated July 31, 2000, which describes 
procedures for modification of the installation of the galley power 
feeder cable. The modification involves installing two standoffs on 
frames at stations Y=924.000 and Y=943.000 and rerouting wire 
assemblies and relocating the wire assembly clamps from the ceiling 
support structure to the new standoffs. That service bulletin 
recommends that McDonnell Douglas Alert Service Bulletin MD90-24A046, 
Revision 02 (the applicable service information specified in NPRM 
Docket No. 2001-NM-149-AD), be accomplished prior to or concurrently 
with modification of the installation of the power feeder cable.

FAA's Conclusions

    Upon consideration, the FAA has determined that it makes technical 
sense to combine the proposed action of NPRM Docket No. 2001-NM-149-AD 
with a new NPRM, Docket No. 2000-NM-197-AD, that proposes 
accomplishment of the previously described modification. Combining 
these actions would also provide a convenience for the operators and 
would not adversely affect safety. Accordingly, the proposed rule is 
hereby withdrawn.
    Withdrawal of this NPRM constitutes only such action, and does not 
preclude the agency from issuing another action 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

    Air transportation, Aircraft, Aviation safety, Safety.

The Withdrawal

    Accordingly, the notice of proposed rulemaking, Docket 2001-NM-149-
AD, published in the Federal Register on August 31, 2001 (66 FR 45948), 
is withdrawn.

    Issued in Renton, Washington, on March 28, 2002.
