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 all 
Airbus Model A318, A319, A320, and A321 series airplanes. This proposed 
AD was prompted by the discovery of corroded circlips in fuel vent 
protectors (FVP) having a certain part number. This proposed AD would 
require an inspection to determine the part number and serial number of 
the FVP, and replacement if necessary. We are proposing this AD to 
detect and correct corroded circlips. Corroded circlips could lead to 
failure of the circlips and consequent movement of the FVP, resulting 
in a reduction of the flame protector capability of the FVP cartridge, 
which could result in damage to the airplane in case of lightning 
impact or fire on the ground.

DATES: We must receive comments on this proposed AD by February 8, 
2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR

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 2014-0234R1, dated December 11, 2014 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model 
A318, A319, A320, and A321 series airplanes. The MCAI states:

    On each aeroplane wing, a NACA [National Advisory committee for 
Aeronautics] duct assembly is installed, including a Fuel Vent 
Protector (FVP) which is used as flame arrestor. This FVP is 
maintained in its NACA duct assembly by a circlip (also known as C-
clip). Following a wing water pressure test, the FVP is removed and 
dried with heat. During an inspection after this test, several 
circlips were reported to be discoloured. Investigation revealed 
that a batch of circlips fitted on some FVP Part Number (P/N) 
786073-1-0 have an increased risk of corrosion due to a 
manufacturing quality issue.
    This condition, if not detected and corrected, could lead to 
circlip failure and consequent FVP movement, reducing the flame 
protector capability of the FVP cartridge, possibly resulting in 
damage to the aeroplane in case of lightning impact or fire on 
ground.
    For the reason described above, EASA issued AD 2014[dash]0234 to 
require identification by serial number (s/n) of the affected FVP P/
N 786073-1-0 and removal from service [and replacement with a 
serviceable part].
    This [EASA] AD is revised to clarify that only maintenance 
records since August 2012 should be consulted to demonstrate, as 
required by paragraph (2), that not replacement FVP has been 
installed.

    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-
7526.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A320-28-1221, dated July 21, 
2014. The service information describes procedures for inspecting the 
FVP to determine the part number, and replacing the FVP if necessary. 
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.

Costs of Compliance

    We estimate that this proposed AD affects 7 airplanes of U.S. 
registry.
    We also estimate that it would take about 5 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Parts would cost $25,640. Based on 
these figures, we estimate the cost of this proposed AD on U.S. 
operators to be up to $182,455, or $26,065 per product.

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

[[Page 79744]]

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.

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):

Airbus: Docket No. FAA-2015-7526; Directorate Identifier 2014-NM-
217-AD.

(a) Comments Due Date

    We must receive comments by February 8, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the airplanes specified in paragraphs (c)(1), 
(c)(2), (c)(3), and (c)(4) of this AD, certificated in any category, 
all manufacturer serial numbers.
    (1) Airbus Model A318-111, -112, -121, and -122 airplanes.
    (2) Airbus Model A319-111, -112, -113, -114, -115,-131, -132, 
and -133 airplanes.
    (3) Airbus Model A320-211, -212, -214, -231, -232, and -233 
airplanes.
    (4) Airbus Model A321-111, -112, -131, -211, -212, -213, -231,

(d) Subject

    Air Transport Association (ATA) of America Code 28, Fuel.

(e) Reason

    This AD was prompted by the discovery of corroded circlips in 
fuel vent protectors (FVP) having a certain part number. We are 
issuing this AD to detect and correct corroded circlips. Corroded 
circlips could lead to failure of the circlips and consequent 
movement of the FVP, resulting in a reduction of the flame protector 
capability of the FVP cartridge, which could result in damage to the 
airplane in case of lightning impact or fire on the ground.

(f) Compliance

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

(g) Inspection of FVP and Corrective Action

    For airplanes having a manufacturer serial number specified in 
figure 1 to paragraphs (g) and (i) of this AD: At the earliest of 
the times specified in paragraphs (h)(1), (h)(2), and (h)(3) of this 
AD, do an inspection to determine the part number and serial number 
of the FVP. If the FVP has part number (P/N) 786073-1-0 with a 
serial number that is specified in figure 2 to paragraphs (g) and 
(i) of this AD, and the FVP is not marked ``Amdt B,'' replace the 
FVP with a serviceable part, at the earliest of the times specified 
in paragraphs (h)(1), (h)(2), and (h)(3) of this AD, in accordance 
with the Accomplishment Instructions of Airbus Service Bulletin 
A320-28-1221, dated July 21, 2014. A review of airplane maintenance 
records is acceptable in lieu of this inspection if the part number 
and serial number of the FVP can be conclusively determined from 
that review.
