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 certain 
Airbus Model A318 series airplanes; Model A319 series airplanes; Model 
A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321-
111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This AD 
was prompted by reports of fatigue damage in the structure for the door 
stop fittings on certain fuselage frames (FR). This AD requires 
repetitive rototest inspections for cracking of the fastener holes in 
certain door stop fittings, and repair if necessary. We are issuing 
this AD to address the unsafe condition on these products.

DATES: This AD is effective March 19, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 19, 
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 certain Airbus Model A318 
series airplanes; Model A319 series airplanes; Model A320-211, -212, -
214, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -
211, -212, -213, -231, and -232 airplanes. The NPRM published in the 
Federal Register on July 25, 2017 (82 FR 34449) (``the NPRM''). The 
NPRM was prompted by reports of fatigue damage in the structure for the 
door stop fittings on certain fuselage frames. The NPRM proposed to 
require repetitive rototest inspections for cracking of the fastener 
holes in certain door stop fittings, and repair if necessary. We are 
issuing this AD to detect and correct cracking at the door stop fitting 
holes of fuselage FR66 and FR68. Such cracking could result in reduced 
structural integrity of the airplane due to the failure of structural 
components.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2016-0238, dated December 2, 2016; corrected January 4, 2017 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A318 series airplanes; Model A319 series airplanes; Model A320-211, -
212, -214, -231, -232, and -233 airplanes; and Model A321-111, -112, -
131, -211, -212, -213, -231, and -232 airplanes. The MCAI states:

    During an A320 fatigue test campaign, it was determined that 
fatigue damage could appear at the door stop fitting holes of 
fuselage frame (FR) 66 and FR 68 on left hand (LH) and right hand 
(RH) sides.
    This condition, if not detected and corrected, could affect the 
structural integrity of the airframe.
    Two inspections, Airworthiness Limitations Item (ALI) tasks 
534129 and 534130, were introduced in the Airworthiness Limitations 
Section (ALS) Part 2 with the April 2012 revision and with some 
compliance time changes with Revision 3 of ALS Part 2 of October 
2014.
    Since these ALI tasks were implemented, a significant number of 
reports [were] received concerning non-critical damage and early 
crack findings. Prompted by these reports, Airbus published SB A320-
53-1288 and SB A320-53-1290, providing inspection instructions to 
improve damage management and modification instructions.
    Consequently, EASA issued AD 2016-0015, requiring repetitive 
rototest inspections of the affected door stop fitting holes and, 
depending on findings, repair of any cracked area(s).
    Since that [EASA] AD was issued, ALS Part 2 Revision 04 and 
later on Revision 05 were published, introducing updated thresholds 
and/or intervals for some tasks as specified in Airbus SB A320-53-
1288, introducing new configuration of aeroplane with RETRO WING 
having accomplished SB A320-57-1193 (mod 160080), and keeping the 
threshold or interval only in flight cycles (FC).
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2016-0015, which is superseded, but requires 
those actions within the updated thresholds and intervals. In 
addition, a corrected threshold for pre-mod 160021 A321 aeroplanes 
is introduced and the Applicability is reduced to exclude 
configurations that are not affected.
    This [EASA] AD is republished to clarify some requirements in 
Appendix 1 [in this EASA AD].

    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-
0707.

Comments

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

Request To Add a Grace Period for Certain Repetitive Inspections

    United Airlines (UAL) requested that we revise paragraph (h) of the 
proposed AD to allow a 60-day grace period after

[[Page 5907]]

the effective date of this AD to give operators time to update their 
maintenance programs. UAL noted that for airplanes on which inspections 
were previously accomplished as specified in airworthiness limitation 
item (ALI) task 534129 or 534130, paragraph (h) of the proposed AD 
requires future inspections be done in accordance with Airbus Service 
Bulletin A320-53-1288, Revision 01, including Appendixes 01, 02, and 
03, dated October 3, 2016. UAL noted that operators who are not yet 
incorporating Airbus Service Bulletin A320-53-1288, Revision 01, 
including Appendixes 01, 02, and 03, dated October 3, 2016, may have to 
schedule special inspection visits instead of doing the inspections 
during scheduled maintenance.
    We agree with the commenter's request to add a grace period to 
paragraph (h) of this AD to allow operators to plan for the new 
inspection interval. However, since the commenter did not provide 
adequate justification to support a 60-day grace period, we have 
determined that a 30-day grace period is appropriate. Additionally, 
under the provisions of paragraph (q)(1) of this AD, we will consider 
requests for approval of an extension of the compliance time if 
sufficient data are submitted to substantiate that the new compliance 
time would provide an acceptable level of safety. We have revised 
paragraph (h) of this AD to include a 30-day grace period.

Request To Allow Deviations From the Service Information for Certain 
Modified Airplanes

    UAL requested that either the service information or the proposed 
AD be revised to provide alternate instructions for airplanes with 
modified hardware. UAL noted that ``paragraph (i)'' of the proposed AD 
requires repetitive inspections on airplanes modified by cold working 
fastener holes, which includes installing oversize hardware. UAL 
pointed out that the inspections must be done in accordance with Airbus 
Service Bulletin A320-53-1288, Revision 01, including Appendixes 01, 
02, and 03, dated October 3, 2016, which requires using nominal size 
hardware that no longer exists on modified airplanes.
    We infer that the commenter meant to refer to paragraph (j) of the 
proposed AD, which discusses post-modification inspections, rather than 
paragraph (i) of the proposed AD, which discusses an optional 
modification. We agree with the commenter's request. We acknowledge 
that Airbus Service Bulletin A320-53-1288, Revision 01, including 
Appendixes 01, 02, and 03, dated October 3, 2016, does not specifically 
address oversize hardware; however, EASA has stated that ``the same 
inspection principle applies for post SB [Service Bulletin] 53-1290 
configuration.'' Therefore, we have retained Airbus Service Bulletin 
A320-53-1288, Revision 01, including Appendixes 01, 02, and 03, dated 
October 3, 2016, in paragraph (j) of this AD. We have also revised 
paragraph (j) of this AD to include an option for operators to obtain 
inspection instructions using a method approved by the Manager, 
International Section, Transport Standards Branch, FAA; or EASA; or 
Airbus's EASA Design Organization Approval (DOA).

Request To Remove a Reference to a Non-Terminating Action

    UAL requested that we remove the statement ``repair of an airplane 
as required by this paragraph does not constitute terminating action 
for the repetitive inspections required by paragraph (g) or (j) of this 
AD for that repair, unless specified otherwise'' from paragraph (k) of 
the proposed AD. UAL suggested that statement be replaced with one 
instructing operators to accomplish inspections as specified in the 
repair instructions.
    UAL noted that paragraph (k) of the proposed AD states that a crack 
repair must be done using a method approved by the Manager, 
International Section, Transport Standards Branch, FAA; or EASA; or 
Airbus's EASA DOA and says that such a repair does not constitute 
terminating action for the repetitive inspections done in accordance 
with Airbus Service Bulletin A320-53-1288, Revision 01, including 
Appendixes 01, 02, and 03, dated October 3, 2016, unless specified 
otherwise.
    UAL pointed out that Airbus Service Bulletin A320-53-1288, Revision 
01, including Appendixes 01, 02, and 03, dated October 3, 2016, 
contains language to allow operators to accomplish crack repairs in 
accordance with structural repair manual (SRM) 53-41-12, and then 
perform inspections of the repaired area in accordance with SRM 53-41-
12. UAL noted that the SRM repair instructions do not state that they 
terminate the inspections in Airbus Service Bulletin A320-53-1288, 
Revision 01, including Appendixes 01, 02, and 03, dated October 3, 
2016. UAL further noted that Airbus Service Bulletin A320-53-1288, 
Revision 01, including Appendixes 01, 02, and 03, dated October 3, 
2016, only applies to unrepaired areas with nominal size holes (the 
repaired areas would have oversized holes).
    We disagree with the commenter's request. We acknowledge that 
Airbus Service Bulletin A320-53-1288, Revision 01, including Appendixes 
01, 02, and 03, dated October 3, 2016, allows repairs to be done using 
an SRM. However, this AD does not include that allowance since SRMs 
published before the effective date of this AD might not address the 
unsafe condition identified in this AD. Therefore, paragraph (k) of 
this AD requires repairs to be done using a method approved by the 
Manager, International Section, Transport Standards Branch, FAA; or 
EASA; or Airbus's EASA DOA.
    Additionally, the statement that the commenter requested us to 
remove from paragraph (k) of this proposed AD aligns with the MCAI. The 
statement is meant to clarify that doing a repair does not necessarily 
terminate the repetitive inspections; the repetitive inspections would 
only be terminated if the repair approved by the Manager, International 
Section, Transport Standards Branch, FAA; or EASA; or Airbus's EASA DOA 
specifically states that the inspections are terminated. If the 
approved repair does not state that the inspections are terminated, 
operators must continue to inspect using Airbus Service Bulletin A320-
53-1288, Revision 01, including Appendixes 01, 02, and 03, dated 
October 3, 2016, or using a method approved by the Manager, 
International Section, Transport Standards Branch, FAA; or EASA; or 
Airbus's EASA DOA. Therefore, we have not changed the requirements in 
paragraph (k) of this AD nor have we removed the statement identified 
by the commenter. However, we have revised paragraph (g) of this AD to 
include an option for operators to obtain inspection instructions using 
a method approved by the Manager, International Section, Transport 
Standards Branch, FAA; or EASA; or Airbus's EASA DOA.

Request To Remove Requirement To Obtain Certain Inspection Instructions

    UAL requested that we remove paragraph (l)(2) of the proposed AD 
because it has no real purpose. UAL noted that paragraph (l)(2) of the 
proposed AD requires operators to obtain inspection instructions and 
corrective actions for all repaired fastener holes by contacting the 
Manager, International Section, Transport Standards Branch, FAA; or 
EASA; or Airbus's EASA DOA. UAL claimed that if a repair was 
accomplished using the instructions in an SRM or repair design approval 
sheet (RDAS), the repair approval contains, at a minimum, the initial 
compliance threshold. UAL added that it is standard

[[Page 5908]]

practice for operators to contact Airbus prior to the inspection 
threshold if the compliance method and intervals are not yet defined.
    We disagree with the commenter's request. Airbus intends to provide 
specific instructions for airplanes inspected in accordance with ALI 
task 534129 or task 534130 and repaired in accordance with an SRM or 
RDAS published before the effective date of this AD. Since repair 
instructions published before the effective date of this AD might not 
address the unsafe condition identified in this AD, the SRM or RDAS 
instructions might need to be re-evaluated or revised to address the 
unsafe condition. In addition, we do not rely on an operator's standard 
practices, and instead require operators to obtain inspections and 
corrective actions to address the unsafe condition. We have not revised 
this AD regarding this issue.

Request To Clarify Actions for Airplanes With Certain Repairs

    UAL requested that we delete paragraph (n) of the proposed AD. UAL 
noted that paragraph (n) of the proposed AD requires operators to 
determine if a repair was done using an RDAS that is unrelated to ALI 
task 534129 or task 534130. UAL suggested that the repair instructions 
would have to state that the damage was found as a result of the 
applicable ALI, but noted that the ALI task is an inspection that may 
not be referenced in a documented repair. UAL questioned the relevance 
of whether or not a repair was related to ALI task 534129 or task 
534130, noting that the same considerations are given to repair 
instructions, regardless of how damage was found. UAL stated that 
operators would know to seek an alternative method of compliance (AMOC) 
if they cannot inspect a previously repaired area in accordance with 
Airbus Service Bulletin A320-53-1288, Revision 01, including Appendixes 
01, 02, and 03, dated October 3, 2016.
    We disagree with the commenter's request. The intent of paragraph 
(n) of the proposed AD is to require operators to re-evaluate existing 
repairs performed using an Airbus RDAS unrelated to ALI task 534129 or 
task 534130 because those repairs may not address the findings from the 
specific inspection types required by the ALI tasks. Therefore, the 
corresponding repairs might not address the unsafe condition and 
operators might need new instructions. We have not changed this AD in 
this regard.

Request To Verify the Latest Service Information is Referenced

    UAL requested that, prior to the release of this final rule, we 
verify that we are referencing the latest revisions of Airbus Service 
Bulletin A320-53-1288, Revision 01, including Appendixes 01, 02, and 
03, dated October 3, 2016; and Airbus Service Bulletin A320-53-1290, 
Revision 01, dated October 3, 2016.
    We agree with the commenter's request. We have verified that no 
later revisions of the service information have been issued, and no 
change is needed to this AD.

Explanation of Change to the Final Rule

    In the proposed AD, Table 1 to paragraphs (g) and (j) of this AD 
and Table 2 to paragraphs (g) and (j) of this AD included a compliance 
time that stated ``. . . or before November 30, 2017. . . .'' Since 
this final rule will become effective after November 30, 2017, we have 
changed this statement to read ``. . . or within 30 days after the 
effective date of this AD. . . .'' We have determined that this revised 
compliance time addresses the unsafe condition.

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 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 the following service information.
     Airbus Service Bulletin A320-53-1288, Revision 01, 
including Appendixes 01, 02, and 03, dated October 3, 2016. This 
service information describes procedures for rototest inspections for 
cracking of the fastener holes in the airframe structure for the door 
stop fittings installation in FR66 and FR68.
     Airbus Service Bulletin A320-53-1290, Revision 01, dated 
October 3, 2016. This service information describes procedures for cold 
working the fastener holes in the airframe structure for the door stop 
fittings installation in FR66 and FR68.
    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 1,084 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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 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 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:
