80 FR 74042 - Airworthiness Directives; Airbus Airplanes

DEPARTMENT OF TRANSPORTATION
Federal Aviation Administration

Federal Register Volume 80, Issue 228 (November 27, 2015)

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.

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.

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

[[Page 74044]]

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.
