Airworthiness Directives; Airbus Airplanes

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200 and -300 series airplanes; and all Model A340-200, -300, -500, and -600 series airplanes. This proposed AD was prompted by reports that the potable water service panel access door was lost during flight. This proposed AD would require modifying affected potable water service panel access doors. We are proposing this AD to prevent failure of the latching mechanism of the potable water service panel access door, which could result in the loss of the potable water service panel access door during flight, and resultant damage to the airplane (e.g., damage to the trimmable horizontal stabilizer) that could cause loss of control of the airplane.

DATES:

We must receive comments on this proposed AD by January 11, 2016.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2015-0028R1, dated May 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 and -300 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. The MCAI states:

Several cases have been reported in which the potable water service panel access door was lost during flight, causing damage to the trimmable horizontal stabilizer. The results of subsequent investigations showed that these events were due to failure of the latching mechanism of the potable water service panel access door.

This condition, if not corrected, could lead to further cases of in-flight loss of the potable water service panel access door, possibly resulting in injury to persons on ground and/or damage to the aeroplane [(e.g., damage to the trimmable horizontal stabilizer)].

To address this condition, Airbus developed a modification and published Service Bulletin (SB) A330-52-3086, SB A340-52-4094 and SB A340-52-5019, to provide instructions for in-service accomplishment of that modification.

Consequently, EASA issued AD 2015-0028 to require modification of the potable water service panel access door 164AR for A330/A340-200/-300 aeroplanes or 154BR for A340-500/-600 aeroplanes, which includes installation of reinforced hinge screws and more robust latches.

Since that [EASA] AD was issued, it was determined that aeroplanes that have embodied Airbus Mod 201938 (Improvement of latching mechanism of potable water service panel) are also not affected by the requirements of this [EASA] AD.

For the reason described above, this [EASA] AD is revised to exclude post-mod 201938 aeroplanes from the Applicability.

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-5815.

Related Service Information Under 1 CFR Part 51

Airbus has issued the following service information.

• Airbus Service Bulletin A330-52-3086, Revision 01, dated April 25, 2014.
• Airbus Service Bulletin A340-52-4094, Revision 01, dated April 25, 2014.
• Airbus Service Bulletin A340-52-5019, Revision 01, dated April 25, 2014.

The service information describes procedures for modifying the affected potable water service panel access door. 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 NPRM.

FAA's Determination and Requirements of This Proposed 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 proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of these same type designs.

Explanation of “RC” Procedures and Tests in Service Information

The FAA worked in conjunction with industry, under the Airworthiness Directive Implementation Aviation Rulemaking Committee (ARC), to enhance the AD system. One enhancement was a new process for annotating which procedures and tests in the service information are required for compliance with an AD. Differentiating these procedures and tests from other tasks in the service information is expected to improve an owner's/operator's understanding of crucial AD requirements and help provide consistent judgment in AD compliance. The procedures and tests identified as RC (required for compliance) in any service information have a direct effect on detecting, preventing, resolving, or eliminating an identified unsafe condition.

As specified in a NOTE under the Accomplishment Instructions of the specified service information, procedures and tests that are identified as RC in any service information must be done to comply with the proposed AD. However, procedures and tests that are not identified as RC are recommended. Those procedures and tests that are not identified as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an alternative method of compliance (AMOC), provided the procedures and tests identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to procedures or tests identified as RC will require approval of an AMOC.

Costs of Compliance

We estimate that this proposed AD affects 63 airplanes of U.S. registry.

We also estimate that it would take about 21 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $15,280 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $1,075,095, or $17,065 per product.

According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate.

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 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 this 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);

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.
