ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, and A320 series airplanes. This AD was prompted by a cracked upper cardan in the main landing gear (MLG). This AD requires revising the maintenance or inspection program, as applicable, to reduce the life limits for the MLG upper cardan for certain installations. We are issuing this AD to prevent failure of the upper cardan in the MLG, which could result in MLG collapse and subsequent damage to the airplane and injury to occupants. DATES: This AD becomes effective December 10, 2015. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of December 10, 2015.

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 Model A318, A319, and A320 series airplanes. The NPRM published in the Federal Register on March 5, 2015 (80 FR 11964). The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014–0141, dated June 4, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus Model A318, A319, and A320 series airplanes. The MCAI states: During an A320–200 77T main landing gear (MLG) fatigue test by Messier BugattiDowty (MBD), an upper cardan was found with a crack, emanating from the grease hole/ main lug intersection. The affected upper cardan, Part Number (P/N) 201163620, is listed in the applicable Airworthiness Limitations Section (ALS) Part 1 with a demonstrated fatigue life of 60,000 landings. This condition, if not corrected, could lead to MLG upper cardan failure, possibly resulting in MLG collapse and subsequent damage to the aeroplane and injury to occupants. Prompted by these findings and further to analysis, it has been decided to reduce the life limit for certain installations of the P/N 201163620 MLG upper cardan. For the reasons described above, this AD requires implementation of the new life limits, as applicable, and replacement of any affected MLG upper cardan units that have already exceeded the reduced limit. The reduced life limits for the affected MLG upper cardan are expected to be incorporated in a next revision of the Airbus A318/A319/A320/A321 ALS Part 1. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/ #!documentDetail;D=FAA-2015-02440003. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (80 FR 11964, March 5, 2015) and the FAA’s response to each comment. Request To Extend the Compliance Time Delta Airlines (DAL) requested that paragraph (g) of the proposed AD (80 FR E:\FR\FM\05NOR1.SGM 05NOR1 Federal Register / Vol. 80, No. 214 / Thursday, November 5, 2015 / Rules and Regulations 11964, March 5, 2015) be revised so the initial compliance time for replacing the MLG upper cardan is extended and corresponds to that of European Aviation Safety Agency (EASA) AD 2014–0141, dated June 4, 2014. EASA AD 2014–0141 specifies an initial compliance time of ‘‘within 3 months’’ after the effective date of that EASA AD and the proposed AD specified an initial compliance time of prior to the applicable life limit specified in paragraphs (g)(1) through (g)(5), or within 30 days after the effective date of the AD, whichever occurs later. We agree with the commenter’s request. In consideration of the average utilization rate of affected U.S. operators, the practical aspects of an orderly modification of the U.S. fleet during regular maintenance periods, and the availability of required modification parts, we have determined that a 3 month initial compliance time is appropriate for replacing the MLG upper cardan. We have changed paragraph (g) of this AD accordingly. jstallworth on DSK7TPTVN1PROD with RULES Request To Reference Next Higher Part Number Assembly Lufthansa Technik requested that the part number for the next higher assembly of MLG cardan part number (P/N) 201163620 be referenced in the NPRM (80 FR 11964, March 5, 2015). The commenter stated that the NPRM and corresponding EASA AD 2014– 0141, dated June 4, 2014, reference P/N 201163620, but that part number is not identified in the aircraft illustrated parts catalog (AIPC). The commenter is concerned that if operators only look in the AIPC to see if P/N 201163620 is identified, and it is not there, they may falsely think that their airplanes would not be affected by the NPRM. We do not agree with the commenter’s request. Although MLG cardan P/N 201163620 is not included in the AIPC, it is identified in Airbus A318/A319/ A320/A321 ALS Part 1—Safe Life Airworthiness Limitation Items, which is part of the approved type design for these airplanes. Therefore, we have not changed this AD in this regard. Clarification of Parts Installation Limitation In paragraph (j) of the proposed AD (NPRM (80 FR 11964, March 5, 2015), we referred to applicable life limits in paragraphs (g)(1) through (g)(5) of the proposed AD. For airplanes other than those identified paragraphs (g)(1) through (g)(5) of the proposed AD, the life limit is in Airbus A318/A319/A320/ A321 ALS Part 1—Safe Life Airworthiness Limitation, Revision 02, dated May 13, 2011, as specified in VerDate Sep<11>2014 14:34 Nov 04, 2015 Jkt 238001 paragraph (h)(5) of this AD. In addition, if a part is transferred between airplanes, operators must adjust the life limit using the method specified in Airbus A318/A319/A320/A321 ALS Part 1—Safe Life Airworthiness Limitation, Revision 02, dated May 13, 2011, as specified in paragraph (h)(3) of this AD. We have clarified paragraph (j) of this AD by also referring to paragraphs (h)(3) and (h)(5) of this AD. Conclusion We reviewed the relevant data, considered 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 minor changes: • Are consistent with the intent that was proposed in the NPRM (80 FR 11964, March 5, 2015) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (80 FR 11964, March 5, 2015). 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 A318/A319/A320/ A321 ALS Part 1—Safe Life Airworthiness Limitation Items, Revision 02, dated May 13, 2011. This document provides revised instructions and life limits for airworthiness limitations items. 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 of this AD. Costs of Compliance We estimate that this AD affects 851 airplanes of U.S. registry. We also estimate that it will 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. Required parts will cost about $0 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $72,335, 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 PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 68435 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.

The following presents the comments received on the NPRM (79 FR 56682, September 23, 2014) and the FAA’s response to each comment. Supportive Comment United Airlines stated that it concurs with the NPRM (79 FR 56682, September 23, 2014), and agrees that the detection and correction of the missing or misaligned plugs will maintain a higher level of safety. Request To Delay Issuance of the NPRM (79 FR 56682, September 23, 2014) All Nippon Airways (ANA) asked that we delay issuance of the NPRM (79 FR 56682, September 23, 2014) until Boeing Alert Service Bulletin B787–81205– SB530024–00, Issue 001, dated May 15, 2014 (referred to as the appropriate source of service information for accomplishing the specified actions), can be revised. ANA noted that the service information specifies using a stringer plug removal/installation tool, having tool number (T/N) MIT140Z4372–3; however, this tool does not work well for doing the actions. ANA provided the following reasons to substantiate its request: • For the instructions specified in Task 1 of this service information, the connecting tube on the tool (T/N 140Z4372–8/–15) interferes with the fasteners at the section 41/43 joint; therefore, the tool cannot be inserted into the stringers. The connecting tube needs to be shortened in length and trimmed to taper. • For the instructions specified in Task 3 of the service information, the tool (T/N 140Z4372–3) cannot be inserted at stringers 30R through 35R, adjacent to the cargo door, because it won’t bend at the location adjacent to the stringer end and frame. • For the instructions specified in Task 3 of the service information, the tool (T/N 140Z4372–3) is inserted into the stringer from station (STA) 1593 to E:\FR\FM\05NOR1.SGM 05NOR1

Airworthiness Directives; Airbus 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 Model A318, A319, and A320 series airplanes. This AD was 
prompted by a cracked upper cardan in the main landing gear (MLG). This 
AD requires revising the maintenance or inspection program, as 
applicable, to reduce the life limits for the MLG upper cardan for 
certain installations. We are issuing this AD to prevent failure of the 
upper cardan in the MLG, which could result in MLG collapse and 
subsequent damage to the airplane and injury to occupants.

DATES: This AD becomes effective December 10, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 10, 
2015.

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 Model A318, 
A319, and A320 series airplanes. The NPRM published in the Federal 
Register on March 5, 2015 (80 FR 11964).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0141, dated June 4, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model 
A318, A319, and A320 series airplanes. The MCAI states:

    During an A320-200 77T main landing gear (MLG) fatigue test by 
Messier Bugatti-Dowty (MBD), an upper cardan was found with a crack, 
emanating from the grease hole/main lug intersection. The affected 
upper cardan, Part Number (P/N) 201163620, is listed in the 
applicable Airworthiness Limitations Section (ALS) Part 1 with a 
demonstrated fatigue life of 60,000 landings.
    This condition, if not corrected, could lead to MLG upper cardan 
failure, possibly resulting in MLG collapse and subsequent damage to 
the aeroplane and injury to occupants.
    Prompted by these findings and further to analysis, it has been 
decided to reduce the life limit for certain installations of the P/
N 201163620 MLG upper cardan.
    For the reasons described above, this AD requires implementation 
of the new life limits, as applicable, and replacement of any 
affected MLG upper cardan units that have already exceeded the 
reduced limit.
    The reduced life limits for the affected MLG upper cardan are 
expected to be incorporated in a next revision of the Airbus A318/
A319/A320/A321 ALS Part 1.

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2015-0244-0003.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (80 
FR 11964, March 5, 2015) and the FAA's response to each comment.

Request To Extend the Compliance Time

    Delta Airlines (DAL) requested that paragraph (g) of the proposed 
AD (80 FR

[[Page 68435]]

11964, March 5, 2015) be revised so the initial compliance time for 
replacing the MLG upper cardan is extended and corresponds to that of 
European Aviation Safety Agency (EASA) AD 2014-0141, dated June 4, 
2014. EASA AD 2014-0141 specifies an initial compliance time of 
``within 3 months'' after the effective date of that EASA AD and the 
proposed AD specified an initial compliance time of prior to the 
applicable life limit specified in paragraphs (g)(1) through (g)(5), or 
within 30 days after the effective date of the AD, whichever occurs 
later.
    We agree with the commenter's request. In consideration of the 
average utilization rate of affected U.S. operators, the practical 
aspects of an orderly modification of the U.S. fleet during regular 
maintenance periods, and the availability of required modification 
parts, we have determined that a 3 month initial compliance time is 
appropriate for replacing the MLG upper cardan. We have changed 
paragraph (g) of this AD accordingly.

Request To Reference Next Higher Part Number Assembly

    Lufthansa Technik requested that the part number for the next 
higher assembly of MLG cardan part number (P/N) 201163620 be referenced 
in the NPRM (80 FR 11964, March 5, 2015). The commenter stated that the 
NPRM and corresponding EASA AD 2014-0141, dated June 4, 2014, reference 
P/N 201163620, but that part number is not identified in the aircraft 
illustrated parts catalog (AIPC). The commenter is concerned that if 
operators only look in the AIPC to see if P/N 201163620 is identified, 
and it is not there, they may falsely think that their airplanes would 
not be affected by the NPRM.
    We do not agree with the commenter's request. Although MLG cardan 
P/N 201163620 is not included in the AIPC, it is identified in Airbus 
A318/A319/A320/A321 ALS Part 1--Safe Life Airworthiness Limitation 
Items, which is part of the approved type design for these airplanes. 
Therefore, we have not changed this AD in this regard.

Clarification of Parts Installation Limitation

    In paragraph (j) of the proposed AD (NPRM (80 FR 11964, March 5, 
2015), we referred to applicable life limits in paragraphs (g)(1) 
through (g)(5) of the proposed AD. For airplanes other than those 
identified paragraphs (g)(1) through (g)(5) of the proposed AD, the 
life limit is in Airbus A318/A319/A320/A321 ALS Part 1--Safe Life 
Airworthiness Limitation, Revision 02, dated May 13, 2011, as specified 
in paragraph (h)(5) of this AD. In addition, if a part is transferred 
between airplanes, operators must adjust the life limit using the 
method specified in Airbus A318/A319/A320/A321 ALS Part 1--Safe Life 
Airworthiness Limitation, Revision 02, dated May 13, 2011, as specified 
in paragraph (h)(3) of this AD. We have clarified paragraph (j) of this 
AD by also referring to paragraphs (h)(3) and (h)(5) of this AD.

Conclusion

    We reviewed the relevant data, considered 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 minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (80 FR 11964, March 5, 2015) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 11964, March 5, 2015).
    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 A318/A319/A320/A321 ALS Part 1--Safe Life 
Airworthiness Limitation Items, Revision 02, dated May 13, 2011. This 
document provides revised instructions and life limits for 
airworthiness limitations items. 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 of this AD.

Costs of Compliance

    We estimate that this AD affects 851 airplanes of U.S. registry.
    We also estimate that it will 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. Required parts will cost about $0 per product. 
Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $72,335, 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.

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.

(g)(5) of this AD are total flight cycles accumulated by the MLG 
since first installation on an airplane.
    (2) The life limits specified in paragraphs (g)(1) through 
(g)(5) of this AD are applicable only for the airplane model, 
configuration and WV specified in those paragraphs.
    (3) If a part is transferred between airplanes having a 
different life limit for the MLG unit, adjust the life limit using 
the method specified in Airbus A318/A319/A320/A321 ALS Part 1--Safe 
Life Airworthiness Limitation Items, Revision 02, dated May 13, 
2011.

    Note 1 to paragraphs (h)(3) and (h)(5) of this AD: Airbus A318/
