# AGENCY:

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

# ACTION:

Notice of proposed rulemaking (NPRM). 

# SUMMARY:

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes, and A340-541 and A340-642 airplanes. This proposed AD would require inspecting to determine if certain emergency escape slides/slide rafts (referred to as slide/rafts) are installed in certain crew/passenger doors; and, if so, performing a one-time inspection to determine if the electrical harnesses of the slide/rafts are properly routed, and rerouting the harnesses if necessary. This proposed AD results from a report that a slide/raft failed to deploy properly during a deployment test. We are proposing this AD to detect and correct improper routing of the electrical harnesses of certain slide/rafts, which could prevent proper deployment of the slide/rafts and delay evacuation of passengers and flightcrew during an emergency. 

# DATES:

We must receive comments on this proposed AD by October 27, 2005.

## Discussion 

                    The Direction Ge                                        ne                                        rale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, notified us that an unsafe condition may exist on certain Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes, and A340-541 and A340-642 airplanes. The DGAC has received a report that, during a deployment test, an emergency escape slide/slide raft (referred to hereafter as a “slide/raft”) failed to deploy due to interference from the slide/raft electrical harness, which had been improperly routed during a prior replacement or installation of the slide/raft. This condition, if not corrected, could prevent proper deployment of certain slide/rafts and delay evacuation of passengers and flightcrew during an emergency.                 

## Relevant Service Information 

Airbus has issued All Operators Telex (AOT) A330-25A3272-2005, Revision 01, dated March 24, 2005 (for Model A330-200 and -300 series airplanes); AOT A340-25A4259-2005, Revision 01, dated March 24, 2005 (for Model A340-200 and -300 series airplanes); and AOT A340-25A5091, Revision 02, dated June 1, 2005 (for Model A340-541 and -642 airplanes). The AOTs describe procedures for inspecting for proper routing of the electrical harnesses of the slide/rafts of certain airplane crew/passenger doors and rerouting the harnesses if necessary. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The DGAC mandated the service information and issued French airworthiness directive F-2005-077, dated May 11, 2005, to ensure the continued airworthiness of these airplanes in France. 

## FAA's Determination and Requirements of the Proposed AD 

These airplane models are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DGAC has kept the FAA informed of the situation described above. We have examined the DGAC's findings, evaluated all pertinent information, and determined that we need to issue an AD for airplanes of this type design that are certificated for operation in the United States. 

Therefore, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously. 

## Clarification of Inspection Terminology 

The “inspection” of the electrical harnesses specified in French airworthiness directive F-2005-077 and the AOTs is referred to in this proposed AD as a “general visual inspection.” We have included the definition for a general visual inspection in a note in the proposed AD. 

## Costs of Compliance 

This proposed AD would affect about 25 airplanes of U.S. registry. The proposed actions would take about 3 work hours per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the proposed AD for U.S. operators is $4,875, or $195 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 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.
