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 certain Airbus Model A319-
115, A319-132, A320-214, A320-232, A321-211, A321-213, and A321-231 
airplanes. The NPRM published in the Federal Register on September 19, 
2016 (81 FR 64083).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0234, dated December 8, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A319-115, A319-132, A320-214, A320-232, A321-211, A321-213, and A321-
231 airplanes. The MCAI states:

    A production quality issue was identified concerning tie rod 
assemblies, having Part Number (P/N) starting with D52840212000 or 
D52840212002, which are installed on the main landing gear (MLG) 
hinged fairing assembly. This quality issue affects the cadmium 
plating surface treatment which

[[Page 4774]]

was inadvertently omitted from the rod end threads of the assembly. 
The absence of cadmium plating reduces the corrosion protection 
scheme.
    This condition, if not detected and corrected, could lead to 
galvanic corrosion of the tie rod end threads, possibly resulting in 
rod end failure, loss of a MLG door, and consequent injury to 
persons on ground.
    To address this unsafe condition, Airbus identified the affected 
[manufacturer serial number] MSN and issued [service bulletin] SB 
A320-52-1167 to provide inspection instructions.
    For the reason described above, this [EASA] AD requires a one-
time inspection of the affected MLG hinged fairing tie rod 
assemblies [for the presence of cadmium plating], and, depending on 
findings, replacement of the affected tie rod assembly.

    You may examine the MCAI in the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating Docket No. FAA-2016-
9110.

Comments

    We gave the public the opportunity to participate in developing 
this AD. 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 AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
    <bullet> 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 has issued Service Bulletin A320-52-1167, dated August 6, 
2015. The service information describes procedures for a detailed 
inspection for the presence of cadmium plating on tie rod assemblies 
having certain part numbers, and procedures for replacement of tie rod 
assemblies with no cadmium plating on the rod end threads. 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 20 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                        Cost per    Cost on U.S.
               Action                            Labor cost              Parts cost      product      operators
----------------------------------------------------------------------------------------------------------------
Inspection.........................  2 work-hours x $85 per hour =               $0          $170        $3,400
                                      $170.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that will be required based on the results of the inspection. We have 
no way of determining the number of airplanes that might need these 
replacements:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                Action                            Labor cost                   Parts cost             product
----------------------------------------------------------------------------------------------------------------
Replacement...........................  13 work-hours x $85 per hour =  Not available...........          $1,105
                                         $1,105.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all available costs in our 
cost estimate.

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.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2017-01-06 Airbus: Amendment 39-18773; Docket No. FAA-2016-9110; 
Directorate Identifier 2015-NM-196-AD.

(a) Effective Date

    This AD is effective February 21, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A319-115, A319-132, A320-214, 
A320-232, A321-211, A321-213, and A321-231 airplanes, certificated 
in any category, as identified in Airbus Service Bulletin A320-52-
1167, dated August 6, 2015.

(d) Subject

    Air Transport Association (ATA) of America Code 52, Doors.

(e) Reason

    This AD was prompted by a report of certain tie rod assemblies 
installed on the hinged fairing assembly of the main landing gear 
(MLG) with no cadmium plating on the rod end threads. We are issuing 
this AD to detect and correct the absence of cadmium plating on the 
rod end threads of the tie rod assemblies. The absence of cadmium 
plating could lead to galvanic corrosion of the tie rod end threads, 
resulting in rod end failure, loss of a MLG door, and consequent 
damage to the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Inspection and Corrective Action

    Within 80 months after the airplane's first flight, do a 
detailed inspection of each tie rod assembly having a part number 
(P/N) D52840212000 or D52840212002 at the MLG hinged fairing for the 
presence of cadmium plating (gold colored threads), in accordance 
with the Accomplishment Instructions of Airbus Service Bulletin 
A320-52-1167, dated August 6, 2015. If during the inspection any tie 
rod assembly is found that does not have cadmium plating, before 
further flight, replace the tie rod assembly with a serviceable part 
having the same part number and cadmium plating, in accordance with 
the Accomplishment Instructions of Airbus Service Bulletin A320-52-
1167, dated August 6, 2015.
