# 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                           ( print 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.

## The Proposed Amendment 

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: 

# PART 39—AIRWORTHINESS DIRECTIVES 

1. The authority citation for part 39 continues to read as follows: 

Authority:49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 

2. The Federal Aviation Administration (FAA) amends § 39.13 by removing amendment 39-11822 (65 FR 44672, July 19, 2000) and adding the following new airworthiness directive (AD): 

**McDonnell Douglas:**                                 Docket No. FAA-2005-22557; Directorate Identifier 2005-NM-147-AD.                             

## Comments Due Date

## Unsafe Condition 

(d) This AD results 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 are issuing this AD to prevent a possible flammable condition, which could result in smoke and fire in the forward crew rest area. 

## Compliance 

(e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.

After the effective date of this AD, do the replacement in accordance with McDonnell Douglas Alert Service Bulletin MD11-25A233, Revision 1, dated May 10, 2005. 

# Note 1:

McDonnell Douglas Alert Service Bulletin MD11-25A233 refers to AIM Aviation Service Incorporated Service Bulletin AIM-MD11-25-2, Revision C, dated March 8, 1999; and Revision D, dated March 16, 2005; as additional sources of service information for replacing the upper and lower reading lights in the forward crew rest area.
