Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2015-10-03 for 
certain Airbus Model A330-200 and -300 series airplanes, and Model 
A340-200 and -300 series airplanes. AD 2015-10-03 required a detailed 
inspection for visible chrome of each affected main landing gear (MLG) 
sidestay upper cardan pin, associated nuts, and retainer assembly; pin 
replacement if needed; measurement of cardan pin clearance dimensions 
(gap check); corrective actions if necessary; and a report of all 
findings. This new AD requires a detailed inspection of the upper 
cardan pin and nut threads for any corrosion, pitting, or thread 
damage, and if necessary, replacement of the cardan pin and nut. This 
new AD also revises the applicability to include additional airplane 
models. This AD was prompted by a report that an MLG sidestay upper 
cardan pin migration event had been caused by corrosion due to lack of 
jointing compound and inadequate sealant application during the MLG 
installation. We are issuing this AD to detect and correct migration of 
the sidestay upper cardan pin, which could result in disconnection of 
the sidestay upper arm from the airplane structure, and could result in 
a landing gear collapse and consequent damage to the airplane and 
injury to occupants.

DATES: This AD is effective August 16, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 16, 
2016.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2015-10-03, Amendment 39-18158 (80 FR 30608, 
May 29, 2015) (``AD 2015-10-03''). AD 2015-10-03 applied to certain 
Airbus Model A330-200 and -300 series airplanes, and Model A340-200 and 
-300 series airplanes. The NPRM published in the Federal Register on 
January 21, 2016 (81 FR 3346) (``the NPRM'').
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0079, dated May 7, 2015 (referred to after 
this as the Mandatory Continuing Airworthiness Information, or ``the 
MCAI''), to correct an unsafe condition for certain Airbus Model A330-
200 and -300 series airplanes, Model A340-200 and -300 series 
airplanes, and Model A340-541 and -642 airplanes. The MCAI states:

    An A330 aeroplane equipped with Basic MLG was rolling out after 
landing when it experienced a nose wheel steering fault (unrelated 
to the safety subject addressed by this AD), which resulted in the 
crew stopping the aeroplane on the taxiway after vacating the 
runway. The subsequent investigation revealed that the right-hand 
MLG sidestay upper cardan pin had migrated out of position. The 
sidestay upper cardan nut and retainer had detached from the upper 
cardan pin and were found, still bolted together, in the landing 
gear bay.
    Prompted by these findings, Airbus published Alert Operators 
Transmission (AOT) A32L003-14, providing inspection instructions 
and, as an interim solution, EASA issued AD 2014-0066 [which 
corresponds to FAA AD 2015-10-03, Amendment 39-18158 (80 FR 30608, 
May 29, 2015)] to require repetitive detailed inspections (DET) of 
the MLG upper cardan pin, nut and retainer. That AD also required 
accomplishment of a one-time gap check between wing rear spar 
fitting lugs and the bush flanges and, depending on findings, 
corrective action(s). The gap check (including corrections, as 
necessary) terminated the repetitive DET.
    Since that [EASA] AD was issued, further investigation concluded 
that the reported MLG sidestay upper cardan pin migration event had 
been caused by corrosion, due to lack of jointing compound and 
inadequate sealant application during MLG installation. Therefore, 
this issue affects any MLG that had an upper cardan pin replacement 
or re-installation, irrespective of MLG overhaul. Any corrosion on 
the upper cardan pin and nut threads would not have been detected 
during the previously required DET.
    This condition, if not detected and corrected, could lead to a 
complete migration of the sidestay upper cardan pin and a 
disconnection of the sidestay upper arm from the aeroplane 
structure, possibly resulting in MLG collapse with consequent damage 
to the aeroplane and injury to occupants.
    To address this potential unsafe condition, Airbus published 
Service Bulletin (SB) A330-32-3269, SB A340-32-4301 and SB A340-32-
5115 providing inspection instructions. In addition, to prevent any 
improper re-installation of an upper cardan pin on a MLG, Airbus 
amended the applicable Aircraft Maintenance Manual (AMM) on 01 
October 2014.
    For the reasons described above, this [EASA] AD supersedes EASA 
[AD] 2014-0066 and requires a one-time DET of the MLG upper cardan 
pin and nut threads to check for corrosion or damage on the upper 
cardan pin and nut threads, and, depending on findings, replacement 
of the damaged part(s).
    As this unsafe condition could also develop on A330 freighters 
and A340-500/ -600 aeroplanes, this [EASA] AD also applies to those 
aeroplanes.

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-
0459.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM and 
the FAA's response to that comment.

[[Page 44995]]

Request To Use the Latest Service Information

    American Airlines (AA) requested that we use the latest service 
information in the NPRM. AA stated that since the NPRM was issued, 
Airbus released Service Bulletin A330-32-3269, Revision 01, dated 
December 3, 2015.
    We agree with the commenter for the reasons stated above. We have 
reviewed Airbus Service Bulletin A330-32-3269, Revision 01, dated 
December 3, 2015, and there are no substantial changes. In addition, we 
have also reviewed Airbus Service Bulletin A340-32-4301, Revision 01, 
dated December 3, 2015; and Airbus Service Bulletin A340-32-5115, 
Revision 01, dated December 11, 2015. There are no substantial changes. 
We have revised this AD accordingly.

Conclusion

    We reviewed the available data, including the comment 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:
    <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 the following service information:

<bullet> Airbus Service Bulletin A330-32-3269, Revision 01, dated 
December 3, 2015.
<bullet> Airbus Service Bulletin A340-32-4301, Revision 01, dated 
December 3, 2015.
<bullet> Airbus Service Bulletin A340-32-5115, Revision 01, dated 
December 11, 2015.

    The service information describes procedures for a detailed 
inspection of the upper cardan pin and nut threads for any corrosion, 
pitting, or thread damage, and replacement of the cardan pin and nut. 
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 95 airplanes of U.S. registry.
    We also estimate that it will take about 11 work-hours 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 $88,825, or $935 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 12 work-hours and require parts costing $78,136, for a cost 
of $79,156 per product. We have no way of determining the number of 
aircraft that might need this action.

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.
