[Docket No. FAA-2005-22557; Directorate Identifier 2005-NM-147-AD]
RIN 2120-AA64


Airworthiness Directives; McDonnell Douglas Model MD-11 and MD-
11F Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede an existing airworthiness 
directive (AD) that applies to certain McDonnell Douglas Model MD-11 
and MD-11F airplanes. The existing AD currently requires replacement of 
the upper and lower reading lights in the forward crew rest area with a 
redesigned light fixture. This proposed AD would add airplanes to the 
applicability of the existing AD. This proposed AD results from a 
report of the old reading lights being inadvertently sent to an 
additional ten airplanes. We are proposing this AD to prevent a 
possible flammable condition, which could result in smoke and fire in 
the forward crew rest area.

DATES: We must receive comments on this proposed AD by November 14, 
2005.

Discussion

    On July 11, 2000, we issued AD 2000-14-12, amendment 39-11822 (65 
FR 44672, July 19, 2000), for certain McDonnell Douglas MD-11 series 
airplanes. That AD requires replacement of the upper and lower reading 
lights in the forward crew rest area with a redesigned light fixture. 
That AD resulted from reports of burning and smoldering blankets in the 
forward crew rest area due to a reading light fixture that came into 
contact with the blankets after the light was inadvertently left on. We 
issued that AD to prevent a possible flammable condition, which could 
result in smoke and fire in the forward crew rest area.

Actions Since Existing AD Was Issued

    Since we issued AD 2000-14-12, Boeing has issued McDonnell Douglas 
Alert Service Bulletin MD11-25A233, Revision 1, dated May 10, 2005. 
Boeing received a report that the old reading lights were inadvertently 
sent to an additional ten airplanes and subsequently added the 
airplanes to the effectivity of the service bulletin.

Relevant Service Information

    We have reviewed McDonnell Douglas Alert Service Bulletin MD11-
25A233, Revision 1, dated May 10, 2005. The service bulletin describes 
procedures for the replacement of the upper and lower reading lights in 
the forward crew rest area with a redesigned light fixture. The 
procedures are essentially the same as the original issue of the 
service bulletin (referenced as the appropriate source of service 
information for accomplishing the actions required by AD 2000-14-12). 
The service bulletin was revised to add airplanes to the effectivity. 
Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition.
    McDonnell Douglas Alert Service Bulletin MD11-25A233 refers to AIM 
Aviation Service Incorporated Service Bulletin AIM-MD11-25-2, Revision 
D, dated March 16, 2005; as an additional source of service information 
for accomplishment of the replacement.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to develop on other airplanes of the 
same type design. For this reason, we are proposing this AD, which 
would supersede AD 2000-14-12 and would retain the requirements of the 
existing AD. This proposed AD would also add ten airplanes to the 
applicability of the existing AD.

Explanation of Change to Applicability

    We have revised the applicability of the existing AD to identify 
model designations as published in the most recent type certificate 
data sheet for the affected models.

Costs of Compliance

    There are about 81 airplanes of the affected design in the 
worldwide fleet. The existing AD affects about 14 airplanes of U.S. 
registry. This proposed AD would affect an additional 10 airplanes of 
U.S. registry.
    The actions that are required by AD 2000-14-12 and retained in this 
proposed AD take about 1 work hour per airplane, at an average labor 
rate of $65 per work hour. Required parts cost about $933 per airplane. 
Based on these figures, the estimated cost of the currently required 
actions is $998 per airplane.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII, Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
subtitle VII, part A, subpart III, section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We have determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the

[[Page 57221]]

States, on the relationship between the national Government and the 
States, or on the distribution of power and responsibilities among the 
various levels of government.
    For the reasons discussed above, I certify that the proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979); and
    3. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket. See the 
ADDRESSES section for a location to examine the regulatory evaluation.

List of Subjects in 14 CFR Part 39
