Airworthiness Directive · Amendment 39-18956 · Flight controls
Airbus Airplanes
This AD applies to the airplanes, certificated in any category, identified in paragraphs (c)(1) through (c)(4) of this AD, 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 superseding Airworthiness Directive (AD) 2015-22-06 which applied to all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2015-22-06 required revising the After Start Normal Procedures section of the airplane flight manual (AFM) to provide procedures that address latent failures in the spoiler and elevator computer (SEC). This AD requires installing new updated SEC software. This AD was prompted by reports that certain maintenance messages indicated the loss of elevator servo control monitoring performed by SEC 1, SEC 2, or both, during the engine start. We are issuing this AD to address the unsafe condition on these products.
(1) This paragraph restates the requirements of paragraph (g) of AD 2015-22-06, with revised compliance language. For airplanes equipped with SEC hardware C part number (P/N) B372CAM0100 with software standards 122 (P/N B372CAM0101), 124 (P/N B372CAM0102), or 125 (P/N B372CAM0103), on SEC position 1 or 2, or both: Within 30 days after November 20, 2015 (the effective date of AD 2015-22-06), revise the After Start Normal Procedures section of the AFM to include the statement specified in figure 1 to paragraph (g) of this AD. This may be done by inserting a copy of this AD or Airbus A318/A319/A320/A321 Temporary Revision TR572, Issue 1.0, dated August 13, 2015, to the Airbus A318/A319/A320/A321 AFM, into the applicable AFM. When a statement identical to that in figure 1 to paragraph (g) of this AD has been included in the After Start Normal Procedures section of the general revisions of the AFM, the general revisions may be inserted into the AFM, and this AD or Airbus A318/A319/A320/A321 Temporary Revision TR572, Issue 1.0, dated August 13, 2015, to the Airbus A318/A319/A320/A321 AFM, may be removed from the AFM.
(2) Inserting a copy of AD 2015-22-06 into the applicable AFM is acceptable for compliance with the requirement of paragraph (g)(1) of this AD. When a statement identical to that in figure 1 to paragraph (g) of this AD has been included in the After Start Normal Procedures section of the general revisions of the AFM, the general revisions may be inserted into the AFM, and AD 2015-22-06 may be removed from the AFM.

| After both engines start: |
| Turn OFF then ON SEC 1 and SEC 2 one after the other. |
Note 1 to paragraph (g) of this AD: Airbus Operations Engineering Bulletin OEB-50 provides additional information on the subject addressed by this AD.
This paragraph restates the requirements of paragraph (i) of AD 2015-22-06, with no change. For all airplanes: As of November 20, 2015 (the effective date of AD 2015-22-06), do not install SEC hardware C P/N B372CAM0100 with software standard 122 (P/N B372CAM0101), 124 (P/N B372CAM0102), or 125 (P/N B372CAM0103), on SEC position 1 or 2, or both, on any airplane, unless the AFM of the airplane is revised concurrently with that installation, as required by paragraph (g) of this AD.
Within 3 months after the effective date of this AD, comply with the actions in paragraph (i)(1) or (i)(2) of this AD, as applicable.
(1) For an airplane that has received Airbus modification 39429 (installation of SEC hardware C P/N B372CAM0100) in production: Install SEC software standard 126, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-27-1252, Revision 01, dated February 18, 2016.
(2) For an airplane that has not received Airbus modification 39429 in production: Inspect to determine whether an affected SEC software standard is installed. Do the inspection in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-27-1257, Revision 01, dated January 1, 2017, except as required by paragraph (n) of this AD. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the SEC C can be conclusively determined from that review. If an affected SEC software standard is found installed, replace the affected software standard using an installation method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA); or Airbus's EASA Design Organization Approval (DOA).
An airplane on which Airbus modification 161208 has been embodied in production is compliant with the requirements of paragraph (i) of this AD, provided it is determined that no affected SEC software standard, as identified in paragraph (g) of this AD, is installed on that airplane.
After modification of an airplane as required by paragraph (i) of this AD, remove the information specified in Airbus A318/A319/A320/A321 TR572, Issue 1.0, dated August 13, 2015, to the Airbus A318/A319/A320/A321 AFM from the AFM of that airplane.
As of the effective date of this AD, no person may install on any airplane an affected SEC software standard, or a SEC hardware C hosting an affected SEC software standard.
Installation on an airplane of a SEC software standard, or of a SEC hardware standard, approved after April 1, 2016 (the effective date of EASA AD 2016-0056), is acceptable for compliance with the requirements of paragraph (i) of this AD for that airplane, provided the conditions specified in paragraphs (m)(1) and (m)(2) of this AD are met.
(1) The software and hardware standard, as applicable, is approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or EASA; or Airbus's EASA DOA.
(2) Replacement of the affected software standard is done using an installation method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or EASA; or Airbus's EASA DOA.
Subtask 271257-832-006-001 of Airbus Service Bulletin A320-27-1257, Revision 01, dated January 1, 2017, includes incorrect instructions. This AD requires that those instructions be followed as specified in paragraphs (n)(1) and (n)(2) of this AD.
(1) For Subtask 271257-832-006-001, instruction “(b)”: If SEC C 126 software P/N B372CAM0104 is found, no further action is required by this AD.
(2) For Subtask 271257-832-006-001, instruction “(c)”: If SEC C 122 software P/N B372CAM0101, SEC C 124 software P/N B372CAM0102, or SEC C 125 software P/N B372CAM0103 is found, do corrective actions using a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or EASA; or Airbus's EASA DOA.
