Airworthiness Directives; Airbus SAS Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus SAS Model A310 series airplanes. This AD was prompted by a 
determination that new or more restrictive maintenance requirements and 
airworthiness limitations are necessary. This AD requires revising the 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive maintenance requirements and airworthiness 
limitations. We are issuing this AD to address the unsafe condition on 
these products.

DATES: This AD is effective November 2, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 2, 
2018.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all Airbus SAS Model A310 
series airplanes. The NPRM published in the Federal Register on June 1, 
2018 (83 FR 25412). The NPRM was prompted by a determination that new 
or more restrictive maintenance requirements and airworthiness 
limitations are necessary. The NPRM proposed to require revising the 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive maintenance requirements and airworthiness 
limitations.
    We are issuing this AD to address prevent fatigue cracking, damage, 
or corrosion in principal structural elements, which could result in 
reduced structural integrity 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 
2017-0206, dated October 12, 2017 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus Model A310 series airplanes. 
The MCAI states:

    The airworthiness limitations for the Airbus A310 aeroplanes, 
which are approved by EASA, are currently defined and published in 
the Airbus A310 Airworthiness Limitations Section (ALS) documents. 
The Damage Tolerant Airworthiness Limitation Items are specified in 
the A310 ALS Part 2. These instructions have been identified as 
mandatory for continuing airworthiness.
    Failure to accomplish these instructions could result in an 
unsafe condition.
    EASA previously issued AD 2016-0217 [which corresponds to FAA AD 
2017-21-08, Amendment 39-19079 (82 FR 48904, October 23, 2017) (``AD 
2017-21-08'')] to require compliance with the maintenance 
requirements and associated airworthiness limitations defined in 
Airbus A310 ALS Part 2 Revision 01, Variation 1.1 and Variation 1.2.
    Since that [EASA] AD was issued, new or more restrictive 
maintenance requirements and associated airworthiness limitations

[[Page 48931]]

were approved by the EASA. Consequently, Airbus published Revision 
02 of the A310 ALS Part 2, compiling all ALS Part 2 changes approved 
since previous Revision 01.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2016-0217, which is superseded, and requires 
accomplishment of the actions specified in Airbus A310 ALS Part 2 
Revision 02.

    The unsafe condition is fatigue cracking, damage, or corrosion in 
principal structural elements, which could result in reduced structural 
integrity of the airplane. 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-2018-0491.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this final rule as proposed, 
except for minor editorial changes. We have determined that these minor 
changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing 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

    Airbus SAS has issued A310 Airworthiness Limitations Section (ALS), 
Part 2, ``Damage Tolerant Airworthiness Limitation Items (DT-ALI),'' 
Revision 02, dated August 28, 2017. This service information describes 
airworthiness limitations applicable to the DT-ALIs. 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 6 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:
    We have determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although we 
recognize that this number may vary from operator to operator. In the 
past, we have estimated that this action takes 1 work-hour per 
airplane. Since operators incorporate maintenance or inspection program 
changes for their affected fleet(s), we have determined that a per-
operator estimate is more accurate than a per-airplane estimate. 
Therefore, we estimate the total cost per operator to be $7,650 (90 
work-hours x $85 per work-hour).

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 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 and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    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.
