AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION: Final rule.

––––––––––––––––––––––––––––––––––

Summary:
We are superseding Airworthiness Directive (AD) 2014-26-10, which applied to all
Airbus Model A318, A319, A320, and A321 series airplanes. AD 2014-26-10 required revising the
maintenance or inspection program to incorporate maintenance requirements and airworthiness
limitations. This new AD requires revising the maintenance or inspection program, as applicable, to
incorporate new or revised airworthiness limitation requirements. This AD was prompted by a
determination that more restrictive maintenance instructions and airworthiness limitations are
necessary. We are issuing this AD to address the unsafe condition on these products.

Dates:
This AD is effective November 1, 2017.
The Director of the Federal Register approved the incorporation by reference of a certain
publication listed in this AD as of November 1, 2017.
The Director of the Federal Register approved the incorporation by reference of a certain other
publication listed in this AD as of February 25, 2015 (80 FR 2813, January 21, 2015).

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD
2014-26-10, Amendment 39-18061 (80 FR 2813, January 21, 2015) (“AD 2014-26-10”). AD 2014-
26-10 applied to all Airbus Model A318, A319, A320, and A321 series airplanes. The NPRM
published in the Federal Register on April 13, 2017 (82 FR 17770). The NPRM was prompted by a
determination that more restrictive maintenance instructions and airworthiness limitations are
necessary. The NPRM proposed to require revising the maintenance or inspection program, as
applicable, to incorporate new or revised airworthiness limitation requirements. The NPRM also
proposed to remove airplanes from the applicability. We are issuing this AD to mitigate the risks
associated with aging effects of airplane systems. Such aging effects could change the characteristics
of the systems leading to an increased potential for failure, which could result in failure of certain
life-limited parts, and reduced structural integrity or reduced controllability 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 AD 2016-0093, dated May 13, 2016 (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:

The airworthiness limitations for Airbus A320 family aeroplanes are currently defined
and published in Airbus A318/A319/A320/A321 Airworthiness Limitations Section
(ALS) documents. The airworthiness limitations applicable to the System Equipment
Maintenance Requirements, which are approved by [European Aviation Safety
Agency] EASA, are specified in ALS Part 4.

The instructions contained in the ALS Part 4 have been identified as mandatory
actions for continued airworthiness. Failure to comply with these instructions could
result in an unsafe condition.

Previously, EASA issued AD 2013-0146 [which corresponds to FAA AD 2014-26-10]
to require accomplishment of all maintenance actions as described in ALS Part 4 at
Revision 01. The new ALS Part 4 Revision 03 (hereafter referred to as ‘the ALS' in
this AD) includes new and/or more restrictive requirements. ALS Part 4 Revision 03,
issue 02, has been released to include editorial changes.



2
For the reason described above, this [EASA] AD retains the requirements of EASA
AD 2013-0146, which is superseded, and requires accomplishment of the actions
specified in the ALS.

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-2017-0248.

Comments

We gave the public the opportunity to participate in developing this AD. We considered the
comments received. Camp Systems International, Daniel Systems Inc., and United Airlines supported
the NPRM.

Request To Incorporate Current ALS Revision

American Airlines (AAL) asked that a provision be incorporated into the proposed AD to
approve use of Airbus A318/A319/A320/A321 ALS Part 4, “System Equipment Maintenance
Requirements (SEMR)”, Revision 05, dated April 6, 2017 (“ALS Part 4, Revision 05”), as an
additional means of compliance with the maintenance or inspection program. AAL stated that ALS
Part 4, Revision 05 is the latest revision level for ALS Part 4, and approving it would potentially
alleviate a future alternative method of compliance (AMOC) request.
We acknowledge the commenter's concern. We have issued global AMOCs to AD 2014-26-10,
which allow all operators of U.S.-registered airplanes to use Airbus A318/A319/A320/A321 ALS
Part 4, “System Equipment Maintenance Requirements (SEMR)”, Revision 04, dated July 6, 2016,
and Airbus A318/A319/A320/A321 ALS Part 4, “System Equipment Maintenance Requirements
(SEMR)”, Revision 05, dated April 6, 2017. These AMOCs are included in paragraph (k)(1)(ii) of
this AD, which states that AMOCs approved previously for AD 2014-26-10 are approved as AMOCs
for the corresponding provisions of paragraph (g) of this AD. In addition, these AMOCs are also
applicable to the revision required by paragraph (i) of this AD. Therefore, we have added paragraph
(k)(1)(iii) to this AD to specify the previous AMOCs that are approved for the provisions of
paragraph (i) of this AD.

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 change described previously and minor
editorial changes. We have determined that these minor 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.
We also determined that these changes will not increase the economic burden on any operator or
increase the scope of this AD.

Related Service Information Under 1 CFR part 51

Airbus has issued Airbus A318/A319/A320/A321 ALS Part 4, “System Equipment Maintenance
Requirements (SEMR),” Revision 03 at Issue 02, dated January 22, 2016. This service information
describes preventive maintenance requirements and includes updated inspections and intervals to be
incorporated into the maintenance or inspection program. 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 1,032 airplanes of U.S. registry.

The actions required by AD 2014-26-10, and retained in this AD take about 1 work-hour per
product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of
the actions that are required by AD 2014-26-10 is $85 per product.
We also estimate that it would take about 1 work-hour per product to comply with the basic
requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we
estimate the cost of this AD on U.S. operators to be $87,720, or $85 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.
This proposed AD is issued in accordance with authority delegated by the Executive Director,
Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order,
issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during
this transition period, the Executive Director has delegated the authority to issue ADs applicable to
transport category airplanes to the Director of the System Oversight Division.

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 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 under the criteria of the Regulatory Flexibility Act.
