Airworthiness Directive · Amendment 39-18852 · Fuel
Airbus Airplanes
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, and -232 airplanes.
We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320-211, -212, -214, -231, -232, and -233 airplanes, and A321 series airplanes. This AD was prompted by the discovery of corroded circlips in fuel vent protectors (FVP) having a certain part number. This AD requires an inspection to determine the part number and serial number of the FVP, and replacement if necessary; and application of sealant on certain nuts and bolts of the National Advisory Committee for Aeronautics (NACA) duct assembly. We are issuing this AD to address the unsafe condition on these products.
For airplanes having a manufacturer serial number specified in figure 1 to paragraphs (g) and (i) of this AD: At the time specified in paragraph (h) 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 time specified in paragraph (h) of this AD, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-28-1221, Revision 02, dated January 11, 2016. 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.

Do the actions required by paragraph (g) of this AD at the earliest of the times specified in paragraphs (h)(1), (h)(2), and (h)(3) of this AD, or within 30 days after the effective date of this AD, whichever occurs later.
(1) Before the accumulation of 5,000 total flight cycles after the date of manufacture of the airplane.
(2) Before the accumulation of 7,500 total flight hours after the date of manufacture of the airplane.
(3) Within 30 months after the date of manufacture of the airplane.
An airplane that does not have a manufacturer serial number specified in figure 1 to paragraphs (g) and (i) of this AD is excluded from the requirements of paragraph (g) of this AD, provided that a FVP having P/N 786073-1-0 with a serial number specified in figure 2 to paragraphs (g) and (i) of this AD has not been installed on that airplane after July 2012. If a FVP having P/N 786073-1-0 with a serial number specified in figure 2 to paragraphs (g) and (i) of this AD is installed, or the serial number cannot be identified: Within 12 months after the effective date of this AD, replace the FVP with a serviceable part, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-28-1221, Revision 02, dated January 11, 2016. A review of airplane maintenance records is acceptable if it can be conclusively determined from that review that a FVP having a serial number specified in figure 2 to paragraphs (g) and (i) of this AD has not been installed on that airplane after July 2012.
As of the effective date of this AD, a FVP having P/N 786073-1-0 and a serial number listed in figure 2 to paragraphs (g) and (i) of this AD may be installed on any airplane, provided the FVP is marked with “Amdt B.”
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
