AGENCY: Federal Aviation Administration (FAA), Department of 

Transportation (DOT).



ACTION: Final rule.



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



SUMMARY: 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.

Discussion



    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2015-22-06, Amendment 39-18311 (80 FR 68429, 

November 5, 2015) (``AD 2015-22-06''). AD 2015-22-06 applied to all 

Airbus Model A318, A319, A320, and A321 series airplanes. The NPRM 

published in the Federal Register on December 20, 2016 (81 FR 92749). 

The NPRM was prompted by reports that some maintenance messages pointed 

out the loss of elevator servo control monitoring performed by SEC 1, 

SEC 2, or both, during the engine start. The NPRM proposed to continue 

to require revision of the After Start Normal Procedures section of the 

AFM. The NPRM also proposed to require multiple actions depending on 

airplane configuration. For airplanes with SEC C that have received the 

previous Airbus modification to SEC hardware, the NPRM proposed to 

require a software update and revision to the AFM. For airplanes that 

have not received the modification, the NPRM proposed to require 

inspection of the currently installed SEC hardware to determine if it 

is affected by this AD and to complete a corrective action to update 

the software and AFM as required. We are issuing this AD to prevent an 

undetected loss of redundancy during flight if an affected SEC cannot 

control the related elevator servo control(s), which could result in 

reduced control of the airplane.

    The European Aviation Safety Agency (EASA), which is the Technical 

Agent for the Member States of the European Union, has issued EASA 

Airworthiness Directive, 2016-0056, dated March 18, 2016 (referred to 

after this as the Mandatory Continuing Airworthiness Information, or 

``the MCAI''), to correct an unsafe condition for all Airbus Model A318 

and A319 series airplanes, and Model A320-211, -212, -214, -231, -232, 

and -233, and A321-111, -112, -131, -211, -212, -213, -231, and -232 

airplanes. The MCAI states:



    Following the introduction of new Spoiler and Elevator Computer 

(SEC) hardware C Part Number (P/N) B372CAM0100 with software (SW) 

standards 122, 124 and 125 (identified by P/N B372CAM0101, P/N 

B372CAM0102 and P/N B372CAM0103, respectively, and hereafter 

referred to as an ``affected SEC software standard'' in this [EASA] 

AD), some airlines reported receiving maintenance messages, e.g. 

``SEC OR WIRING FROM L or R ELEV POS MON XDCR'' and/or ``SEC OR 

WIRING FROM G or Y ELEV POS XDCR'', which are associated with servo 

control or elevator transducer monitoring. Such messages are 

triggered by a short data inconsistency due to power transients, 

when the engines are started.

    This condition, if not corrected, could lead to an undetected 

loss of redundancy during flight if an affected SEC cannot control 

the related elevator servo control(s), possibly resulting in reduced 

control of the aeroplane.

    To address this potential unsafe condition, EASA issued AD 2015-

0191 [which corresponds to AD 2015-22-06] to require amendment of 

the applicable [Airbus] Airplane Flight Manual (AFM) to include the 

flight crew procedure necessary to recover full SEC redundancy.

    Since that [EASA] AD was issued, to fix the software deficiency, 

SEC software standard 126 (identified by P/N B372CAM0104) was 

developed, which is embodied in production through Airbus 

modification (mod) 161208 (installation of SEC software standard 

126), and introduced in service through Airbus Service Bulletin (SB) 

A320-27-1252.

    For the reason described above, this [EASA] AD retains the AFM 

change requirements of EASA AD 2015-0191, which is superseded, and 

requires the removal and/or upgrade of [an affected] SEC.



    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-2016-

9508.



Comments



    We gave the public the opportunity to participate in developing 

this AD. The following presents the comments received on the NPRM and 

the FAA's response to each comment.



Support for the NPRM



    The Air Line Pilots Association, International (ALPA), expressed 

its full support for the NPRM.



Request To Extend Compliance Time for Replacement of Affected Software



    American Airlines (AAL) requested that we revise the proposed AD to 

extend the proposed compliance time for replacement of the affected 

software from 3 months to 24 months. AAL mentioned that it has 121 

airplanes, for a total of 363 SEC computers, and that the proposed 

compliance time of 3 months poses a significant burden on its ability 

to comply with the proposed requirements. AAL asserted that an increase 

in the specified compliance time would greatly decrease the burden with 

no added safety risk, due to the revision of the AFM specified in 

paragraph (g) of the proposed AD.

    We do not agree to extend the specified compliance time. The 

operator provided no technical justification for revising this 

compliance time. Further, in developing an appropriate compliance time 

for this action, we considered the urgency associated with the subject 

unsafe condition, the availability of necessary replacement software, 

recommendations from the manufacturer, and the practical aspect of 

accomplishing the required modification within a period of time that 

corresponds to the normal scheduled maintenance for most affected 

operators. We have determined that a 3-month compliance time will 

ensure an acceptable level of safety and allow the software replacement 

to be done during regular maintenance schedules for most affected 

operators. However, under the provisions of paragraph (p)(1) of this 

AD, we will consider requests for approval of an extension of the 

compliance time if sufficient data are submitted to substantiate that 

the new compliance time would provide an acceptable level of safety. We 

have not changed this AD in this regard.



Request To Permit Replacement of SEC in Lieu of Software Standard 126



    AAL requested that we revise paragraph (i)(l) of the proposed AD to 

allow replacement of the SEC in lieu of installation of SEC software 

standard 126. AAL suggested that we add a statement similar to 

paragraph (i)(2) of the proposed AD, to paragraph (i)(1) of the 

proposed AD, allowing replacement of the SEC to be accomplished in 

accordance with an installation method approved by the Manager, 

International Branch, ANM-116, Transport Airplane Directorate, FAA; or 

EASA; or Airbus's EASA Design Organization Approval (DOA). AAL asserted 

that there are cases where the option to replace the SEC in accordance 

with the applicable Airbus airplane maintenance manual or other 

approved methods on airplanes having Airbus modification 39429 would 

benefit operators, especially given the 3-month compliance time.

    We disagree with the request to revise paragraph (i)(1) of this AD. 

As specified in the MCAI, paragraph (i)(1) of this AD applies to 

airplanes with Airbus modification 39429 embodied in production and 

requires installing SEC software standard 126, which is the only 

approved corrective action. The instructions in paragraph (i)(2) of 

this AD only apply to airplanes that have not received the modification 

in production. However, under the provisions of paragraph (p)(1) of 

this AD, we will consider alternative replacements if sufficient data 

are submitted to substantiate that the alternative replacement would 

provide an acceptable level of safety. We have not changed this AD in 

this regard.



[[Page 39349]]



Request To Specify Latest Airbus Service Bulletin



    Airbus requested that we revise the NPRM to reference Airbus 

Service Bulletin A320-27-1257, Revision 01, dated January 1, 2017, for 

the applicable software replacement required by paragraph (i)(2) of 

this AD. Airbus Service Bulletin A320-27-1257, dated December 18, 2015, 

was specified as the appropriate source of service information for the 

proposed SEC software replacement provided in the proposed AD. Airbus 

stated that Airbus Service Bulletin A320-27-1257, Revision 01, dated 

January 1, 2017, was issued to add a maintenance records check for 

determining the part number of the SEC software, and to correct a 

typographical error in a part number in a certain subtask.

    We agree that this AD should specify Airbus Service Bulletin A320-

27-1257, Revision 01, dated January 1, 2017. This service information 

corrects errors in Airbus Service Bulletin A320-27-1257, dated December 

18, 2015, which were noted in the NPRM. No additional work is necessary 

for airplanes on which the actions were performed using Airbus Service 

Bulletin A320-27-1257, dated December 18, 2015. Therefore, we have 

changed this AD to refer to Airbus Service Bulletin A320-27-1257, 

Revision 01, dated January 1, 2017, as the appropriate source of 

service information for the applicable required SEC software 

replacement. We have also added paragraph (o) to this AD to provide 

credit for actions accomplished prior to the effective date of this AD, 

if those actions were performed using Airbus Service Bulletin A320-27-

1257, dated December 18, 2015, and redesignated subsequent paragraphs 

accordingly.



Additional Changes to This AD



    We have revised this AD to provide credit for the software 

replacement required by paragraph (i)(1) of this AD, if those actions 

were performed before the effective date of this AD using Airbus 

Service Bulletin A320-27-1252, dated November 6, 2015. We have also 

moved the content of note 1 to paragraph (g) of the proposed AD to the 

text in paragraph (g) of this AD. We have redesignated the subsequent 

note accordingly. In addition, we have revised paragraph (m) of this AD 

to clarify the provision for installation of equivalent software and 

hardware. The proposed AD referred to the effective date of this AD. 

This AD refers to the effective date of the MCAI.



Conclusion



    We reviewed the available data, including the comments received, 

and determined that air safety and the public interest require adopting 

this AD with the changes described previously and minor editorial 

changes. We have determined that these changes:

     Are consistent with the intent that was proposed in the 

NPRM for correcting the unsafe condition; and

     Do not add any additional burden upon the public than was 

already proposed in the NPRM.



Related Service Information Under 1 CFR Part 51



    We reviewed the following service information:

     Airbus Service Bulletin A320-27-1252, Revision 01, dated 

February 18, 2016.

     Airbus Service Bulletin A320-27-1257, Revision 01, dated 

January 1, 2017.

    This service information provides information for identifying 

affected SECs and updating the software on affected SECs. These 

documents are distinct since they apply to different airplane 

configurations.

    We also reviewed Airbus A318/A319/A320/A321 Temporary Revision 

TR572, Issue 1.0, dated August 13, 2015, to the Airbus A318/A319/A320/

A321 AFM. This service information describes the reset of SEC 1 and SEC 

2 that must be done after engine start.

    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.



Costs of Compliance



    We estimate that this AD affects 959 airplanes of U.S. registry.

    We estimate the following costs to comply with this AD:

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



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 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.

(d) Subject



    Air Transport Association (ATA) of America Code 27, Flight 

controls.



(e) Reason



    This AD was prompted by reports that certain maintenance 

messages were recorded within the post flight report (PFR) that 

indicated the loss of elevator servo control monitoring performed by 

spoiler and elevator computer (SEC) 1, SEC 2, or both, during the 

engine start. We are issuing this AD to prevent an undetected loss 

of redundancy during flight if an affected SEC cannot control the 

related elevator servo control(s), possibly resulting in reduced 

control of the airplane.



(f) Compliance



    Comply with this AD within the compliance times specified, 

unless already done.



(g) Retained Airplane Flight Manual (AFM) Revision, With Revised 

Compliance Language



    (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.

    Note 1 to paragraph (g) of this AD: Airbus Operations 

Engineering Bulletin OEB-50 provides additional information on the 

subject addressed by this AD.



(h) Retained Parts Installation Limitation, With No Change



    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.



(i) New Requirement of This AD: Replacement of Software



    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:

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).



(j) New Requirement of This AD: Compliance for Airplanes Having Airbus 

Modification 161208 Embodied in Production



    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.



(k) New Requirement of This AD: Disposition of AFM After Airplane

    (1) Alternative Methods of Compliance (AMOCs): The Manager, 

International Branch, ANM-116, Transport Airplane Directorate, 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 Branch, send it to the attention of 

the person identified in paragraph (r)(2) of this AD. Information 

may be emailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. 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. The 

AMOC approval letter must specifically reference this AD.

    (2) Contacting the Manufacturer: For any requirement in this AD 

to obtain corrective actions from a manufacturer, the action must be 

accomplished using a method approved by the Manager, International 

Branch, ANM-116, Transport Airplane Directorate, FAA; or EASA; or 

Airbus's EASA DOA. If approved by the DOA, the approval must include 

the DOA-authorized signature.

    (3) Required for Compliance (RC): Except as required by 

paragraph (n) of this AD: If any service information contains 

procedures or tests that are identified as RC, those procedures and 

tests must be done to comply with this AD; any procedures or tests 

that are not identified as RC are recommended. Those procedures and 

tests that are not identified as RC may be deviated from using 

accepted methods in accordance with the operator's maintenance or 

inspection program without obtaining approval of an AMOC, provided 

the procedures and tests identified as RC can be done and the 

airplane can be put back in an airworthy condition. Any 

substitutions or changes to procedures or tests identified as RC 

require approval of an AMOC.
