Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Airbus Model A330-300 series airplanes. This AD requires contacting the 
FAA to obtain instructions for addressing the unsafe condition on these 
products, and doing the actions specified in those instructions. This 
AD was prompted by a report indicating that a pipe of the fire 
extinguishing system in the forward cargo compartment was too long, and 
therefore could be installed only under stress, which applies pressure 
to the pipe clamp. We are issuing this AD to address the unsafe 
condition on these products.

DATES: This AD becomes effective February 27, 2018.
    We must receive comments on this AD by March 29, 2018.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2013-0291, dated December 9, 2013 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Airbus Model A330-300 series 
airplanes. The MCAI states:

    During installation of the fire extinguishing system in the 
forward cargo compartment in production, it was established that one 
pipe was too long and could therefore only be installed under 
stress. This affected pipe was developed in the frame of Airbus mod 
58244 and mod 58245 related to Cabin Intercommunication Data System-
Based smoke detection system (CIDS-Based SDS) for A330-300 
aeroplanes only.
    Investigation revealed that due to loads transfer, the clamp 
could break and the pipe would come into contact with the structure, 
possibly resulting in leakage in the Halon piping due to chafing, in 
the forward lower deck cargo compartment (LDCC), which could lead to 
(potentially undetected) functional loss of fire extinguishing 
system.
    This condition, if not corrected, in combination with a fire, 
could lead to an uncontrolled fire in LDCC, possibly resulting in 
the loss of aeroplane.
    To address this unsafe condition, Airbus developed a mod. which 
consists in installation of a shorter pipe, to be embodied in 
production with mod 202779 and in-service through Airbus Service 
Bulletin (SB) A330-26-3053.
    For the reasons described above, this [EASA] AD requires 
modification of the affected fire extinguishing pipe between [frame] 
FR34 and FR36 in the forward LDCC.

0075.

FAA's Determination and Requirements 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. 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 the same type design.

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this product, we 
find good cause that notice and opportunity for prior public comment 
are unnecessary. In addition, for the reason(s) stated above, we find 
that good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    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-2018-0075; Product 
Identifier 2013-NM-251-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.

Costs of Compliance

    Currently, there are no affected U.S.-registered airplanes. This AD 
requires

[[Page 5905]]

contacting the FAA to obtain instructions for addressing the unsafe 
condition, and doing the actions specified in those instructions. Based 
on the actions specified in the MCAI AD, we are providing the following 
cost estimates for an affected airplane that is placed on the U.S. 
Register in the future:

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

Regulatory Findings

    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.

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

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


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2018-03-20 Airbus: Amendment 39-19193; Docket No. FAA-2018-0075; 
Product Identifier 2013-NM-251-AD.

(a) Effective Date

    This AD becomes effective February 27, 2018.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A330-301, -302, -303, -321, -
322, -323, -341, -342, and -343 airplanes, certificated in any 
category, all manufacturer serial numbers on which Airbus 
modification 58244 or modification 58245 has been embodied in 
production, except those on which modification 202779 has been 
embodied in production.

(d) Subject

    Air Transport Association (ATA) of America Code 26, Fire 
protection.

(e) Reason

    This AD was prompted by a report indicating that a pipe of the 
fire extinguishing system in the forward cargo compartment was too 
long, and therefore could be installed only under stress, which 
applies pressure to the pipe clamp. We are issuing this AD to 
prevent this pipe clamp from breaking, allowing the pipe to come 
into contact with the structure, possibly resulting in leakage in 
the Halon piping. This condition could lead to functional loss of 
the fire extinguishing system, which, in combination with a fire, 
could lead to an uncontrolled fire in the lower deck cargo 
compartment, and possible loss of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Action(s)

    Within 30 days after the effective date of this AD, request 
instructions from the Manager, International Section, Transport 
Standards Branch, FAA, to address the unsafe condition specified in 
paragraph (e) of this AD; and accomplish the actions at the times 
specified in, and in accordance with, those instructions. Guidance 
can be found in Mandatory Continuing Airworthiness Information 
(MCAI) European Aviation Safety Agency (EASA) AD 2013-0291, dated 
December 9, 2013.

(h) Alternative Methods of Compliance (AMOCs)

    The Manager, International Section, Transport Standards Branch, 
FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. In accordance with 14 
CFR 39.19, send your request to your principal inspector or local 
Flight Standards District Office, as appropriate. If sending 
information directly to the International Section, send it to the 
attention of the person identified in paragraph (i)(2) of this AD. 
Information may be emailed to: [email protected]. 
Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
local flight standards district office/certificate holding district 
office.
