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 2014dash0234 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.
List of Subjects in 14 CFR Part 39

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.
