The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2015-0183R1, dated September 29, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Airbus Model A330-200, A330-200 Freighter, A330-300, A340-200, A340-300, A340-500, and A340-600 series airplanes. The MCAI states:

During inspections of two different A330 aeroplanes before delivery, incorrect connection of the girt panel was noticed on one passenger (PAX) door 2 and one PAX door 4. Further investigation revealed that the quick release (girt) bar was incorrectly installed into the girt panel of the affected slide raft.

This condition, if not detected and corrected, would cause the slide pack to remain attached to the door, preventing slide deployment during an emergency (door in “ARMED” mode), leading to reduced evacuation capacity from the aeroplane and possible injury to occupants.

Further inspections at the Airbus final assembly line revealed a third case of incorrect installation of girt panel, on one emergency exit door.

Prompted by these findings, Airbus issued Alert Operators Transmission (AOT) A25L004-15 to provide inspection instructions.

For the reasons described above, EASA issued AD 2015-0183 to require a one-time inspection of the escape slide and slide/raft attachments and, depending on findings, accomplishment of applicable corrective action(s) [including reinstalling the slide or declaring the affected door inoperative].

Since that AD was issued, it was found that the Applicability could be reduced by excluding some aeroplanes and that there was a need to clarify the applicable Airbus MPD Tasks and MRBR MSI.

You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-4203.

Airbus has issued Alert Operators Transmission (AOT) A25L004-15, Rev 00, dated August 24, 2015. The service information describes procedures for performing a visual inspection of the girt installations of each slide and slide raft, and corrective action. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this AD.

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of these same type designs.

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because incorrect girt installation of the of escape slide and slide raft could prevent slide deployment during an emergency and result in reduced evacuation capacity from the airplane and possible injury to occupants. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2015-4203; Directorate Identifier 2015-NM-142-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD based on those comments.

We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.

We estimate that this AD affects 30 airplanes of U.S. registry.

We also estimate that it will take about 1 work-hour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $0 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $2,550, or $85 per product.

In addition, we estimate that any necessary follow-on actions will take about 18 work-hours, for a cost of $1,530 per escape slide/slide raft. We have no way of determining the number escape slides/slide rafts on the aircraft that might need this action.

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.

We determined that this AD will not have federalism implications under Executive Order 13132. This AD will 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 this AD:

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);

3. Will not affect intrastate aviation in Alaska; and

4. 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.

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

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

2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD):
