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 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 May 22, 2017 (82 FR 23160) (``the NPRM''). The NPRM was prompted by a report of cracks on frame forks and outer skin on the forward and aft cargo compartment doors. The NPRM proposed to require repetitive inspections of the frame forks, and corrective actions if necessary. The NPRM also included optional modifications that constitute terminating action. We are issuing this AD to detect and correct cracks on the frame forks and outer skin on the forward and aft cargo compartment doors, which could lead to reduced structural integrity and failure of the cargo compartment door, possible decompression of the airplane, and injury to occupants.
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2016-0187, dated September 19, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Airbus 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 full scale fatigue test, cracks have been found on frame forks and outer skin on forward and aft cargo doors.
To improve the fatigue behaviour of the frame forks, Airbus introduced modification (mod) 22948 in production, and issued inspection Service Bulletin (SB) A320-52-1032 and modification SB A320-52-1042, both recommended.
Since those actions were taken, further improved cargo compartment doors have been introduced in production through Airbus mod 26213, on aeroplanes having manufacturer serial number MSN 0759 and up. This modification, which is not available for in-
service retrofit, also includes provisions that exclude installation of pre-mod 26213 aft and forward compartment cargo doors on an aeroplane.
In the frame of the Widespread Fatigue Damage (WFD) study, it has been determined that repetitive inspections are necessary for aft and forward cargo compartment doors on aeroplanes that do not (or no longer) embody mod 22948 (or SB A320-52-1042), and those that do not embody mod 26213. Failure to detect cracks would reduce the cargo door structural integrity.
This condition, if not detected and corrected, could lead to cargo door failure, possibly resulting in decompression of the aeroplane and injury to occupants.
To address this unsafe condition, Airbus issued SB A320-52-1171 to provide inspection instructions. This SB was later revised to correct the list of affected cargo doors. Airbus also issued SB A320-52-1170, introducing a door modification which constitutes terminating action for the repetitive special detailed inspection (SDI).
For the reason described above, this EASA AD requires accomplishment of repetitive SDI by rototest of all frame forks in beam 4 area to detect cracks, and, depending on findings, accomplishment of applicable corrective action(s) repair or replacement. This AD also provides an optional modification that constitutes terminating action for the repetitive SDI required by this EASA AD.
One of the optional modifications includes related investigative and corrective actions. The related investigative action is a high frequency eddy current (HFEC) rotating probe inspection for cracks, and the corrective action is a repair. 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-2017-0478.
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.
Requests To Refer to Updated Service Information
Delta Air Lines and United Airlines requested that we revise the NPRM to refer to Airbus Service Bulletin A320-52-1171, Revision 02, dated April 10, 2017. United Airlines mentioned that Airbus has made number of updates and clarifications in Airbus Service Bulletin A320-
52-1171, Revision 02, dated April 10, 2017. Additionally, United Airlines pointed out that EASA AD 2016-0187, dated September 19, 2016, quoted in the ``Discussion'' section of the NPRM, allows for use of later approved revisions.
We agree with the commenters for the reasons provided. We have revised this AD to refer to Airbus Service Bulletin A320-52-1171, Revision 02, dated April 10, 2017. We have also redesignated paragraph (m) (of the proposed AD) as paragraph (m)(1) of this AD and added paragraph (m)(2) to provide credit for actions done before the effective date of this AD, if those actions were done using Airbus Service Bulletin A320-52-1171, Revision 01, dated September 5, 2016.
Request To Clarify That Certain Service Information Cancels the Requirements of Certain Other Service Information
United Airlines requested that we clarify that Airbus Service Bulletin A320-52-1171, Revision 02, dated April 10, 2017, cancels the requirements of Airbus Service Bulletin A320-52-1032. The commenter indicated that a statement regarding this subject would clarify the required actions for operators. The commenter also pointed out that a statement is listed in Airbus Service Bulletin A320-52-1171, Revision 02, dated April 10, 2017, that specifies the cancellation of the requirements of Airbus Service Bulletin A320-52-1032.
We agree to clarify. Airbus Service Bulletin A320-52-1171, Revision 02, dated April 10, 2017, does include a statement indicating that the actions specified in Airbus Service Bulletin A320-52-1171, Revision 02, dated April 10, 2017, cancel the actions specified in Airbus Service Bulletin A320-52-1032. However, the actions specified in Airbus Service Bulletin A320-52-1032 are not required by any AD, and therefore, we do not specifically address Airbus Service Bulletin A320-52-1032 in this AD (except for the compliance time reference in paragraph (h)(4) of this AD). We have not changed this AD in this regard.
Page 56160
Request To Update the NPRM To Include Modifications 22948 and 26213
Delta Air Lines requested that we revise paragraphs (c) and (g) of the proposed AD to refer to Modifications 22948 and 26213. Specifically, Delta Air Lines requested that we include information that elaborates on the specific airplanes affected by the NPRM. Delta Air Lines pointed out that EASA AD 2016-0187, dated September 19, 2016, quoted in the ``Discussion'' section of the NPRM, and Airbus Service Bulletin A320-52-1042, Revision 2, dated January 14, 1997, already refer to the modifications. Delta Air Lines also mentioned that it has 40 forward and aft cargo compartment doors affected by the NPRM, which are pre-Modifications 22948 and 26213 and under manufacturer serial number 0758.
We disagree to refer to Modifications 22948 and 26213 in paragraphs (c) and (g) of this AD; however, we agree that clarification is necessary. The applicability of this AD refers to the affected models having manufacturer serial numbers through 0758 inclusive; all airplanes having these serial numbers are affected by the identified unsafe condition. Airbus introduced modification 22948 in production, and issued Airbus Service Bulletin A320-52-1032 for recommended inspections and Airbus Service Bulletin A320-52-1042 for recommended modification 22948. Since that service information was issued, Airbus has introduced further improved forward and aft cargo compartment doors (modification 26213) in production on airplanes having manufacturer serial number 0759 and above; however, this modification is unavailable for in-service retrofit. Modification 26213 includes provisions that prohibit installation of earlier configurations of forward or aft cargo compartment doors (pre-modification 26213). Airplanes having manufacturer serial numbers 0759 and subsequent have modification 26213 installed in production. We have not changed this AD in this regard.
Request To Include Instructions for Rotable Parts
Delta Air Lines requested that we include instructions for rotable parts in paragraph (g) of the proposed AD. The commenter mentioned that forward or aft cargo compartment doors could be migrated from manufacturer serial number 0759 and above to airplanes that are affected, and asked if those airplanes are still affected. The commenter also requested that Airbus provide a list of manufacturer serial numbers that are affected by the proposed AD.
We partially agree with the commenter. Airplanes originally delivered with the affected doors are subject to the requirements of this AD. Paragraph (h) of this AD only requires actions on affected doors. It is not physically possible to install the affected doors on serial numbers 0759 and above; therefore, parts rotability does not need to be addressed in this AD.
In addition, paragraph (n) of this AD provides a parts installation limitation for the forward or aft cargo compartment doors for the airplanes identified in paragraph (c) of this AD. We have no practical method to provide a manufacturer serial number list of affected airplanes on which a non-affected door might have been installed or to predict an airplane configuration in the worldwide fleet. Therefore, we have not changed this AD in this regard.
Request To Clarify Optional Terminating Actions
United Airlines requested that we clarify the optional terminating actions specified in paragraph (j) of the proposed AD. The commenter requested we include a statement that specifies modification of all affected doors of an airplane in accordance with the requirements of paragraphs (j)(1), (j)(2), or (j)(3) of this AD constitutes terminating action. The commenter pointed out that EASA AD 2016-0187, dated September 19, 2016, quoted in the ``Discussion'' section of the NPRM, allows for modification of an airplane as specified in Airbus Service Bulletin A320-52-1042, Revision 2, dated January 14, 1997; or Airbus Service Bulletin A320-52-1170, dated September 5, 2016; and either is considered terminating action for the repetitive inspections.
We agree that clarification is necessary. We have revised paragraph (j) of this AD to include introductory text with the statement: ``Modification of all affected doors of an airplane in accordance with the requirements of paragraph (j)(1), (j)(2), or (j)(3) of this AD constitutes terminating action . . . .''
Request To Include Compliance Times for Optional Terminating Actions
Mr. Petit requested that we add compliance times for the optional terminating actions specified in the proposed AD. Mr. Petit indicated that 14 CFR 26.21 might require a mandatory terminating action before 56,300 flight cycles. Mr. Petit also recommended that the optional terminating action not be embodied before 21,700 flight cycles.
We disagree with the commenter's request to include compliance times for the optional terminating action specified in this AD. 14 CFR 26.21 mandates the limit of validity (LOV) and does not specify compliance times for the optional terminating action specified in this AD. This AD mandates repetitive inspections of the frame forks as specified in the service information provided by the design approval holder (DAH) to meet the LOV. In addition, we do not include compliance times for optional actions in ADs because doing so would make the actions mandatory. We intend for the terminating actions in this AD to be optional, which aligns with the MCAI.
Regarding the commenter's recommendation to prohibit accomplishing the optional terminating action before 21,700 flight cycles, the commenter provided no substantiation for this prohibition. We have received no data indicating that the optional terminating action should not be accomplished before 21,700 flight cycles. Therefore, we have not changed this AD in this regard.
Clarification of Exception
Paragraph (i)(2) of the proposed AD, which refers to Airbus Service Bulletin A320-52-1170, dated September 5, 2016, includes an exception as specified in paragraph (k) of the proposed AD. However, paragraph (k) of the proposed AD does not mention Airbus Service Bulletin A320-
52-1170, dated September 5, 2016. We have added Airbus Service Bulletin A320-52-1170, dated September 5, 2016, to the exception specified in paragraph (k) 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 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.

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:
-
Is not a ``significant regulatory action'' under Executive Order 12866;
-
Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);
-
Will not affect intrastate aviation in Alaska; and
-
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.

Accomplishment of applicable corrective actions does not constitute terminating action for the repetitive inspections.
(j) Optional Terminating Action
Modification of all affected doors of an airplane in accordance with the requirements of paragraph (j)(1), (j)(2), or (j)(3) of this AD, constitutes terminating action for the repetitive inspections specified in paragraph (h) of this AD for that airplane.
(1) Modification of all affected doors of an airplane in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-52-1042, Revision 2, dated January 14, 1997, constitutes terminating action for the repetitive inspections specified in paragraph (h) of this AD for that airplane, provided that, after modification, no affected door is re-installed on that airplane.
(2) Modification of all affected doors of an airplane including accomplishment of all applicable related investigative and corrective actions in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-52-1170, dated September 5, 2016, except as specified in paragraph (k) of this AD, constitutes terminating action for the repetitive inspections specified in paragraph (h) of this AD for that airplane, provided that, after modification, no affected door is re-installed on that airplane.
(3) Modification of all affected doors on an airplane, in case of finding damaged frame forks, as specified in an Airbus Repair Design Approval Sheet (RDAS), and done in accordance with a method approved by the Manager, International Section, Transport Standards Branch, FAA; or the European Aviation Safety Agency (EASA); or Airbus's EASA Design Organization Approval (DOA); constitutes terminating action for the repetitive inspection specified in paragraph (h) of this AD for that airplane, provided that, after modification, no affected door is re-installed on that airplane.
(k) Exception to Service Information
Where Airbus Service Bulletin A320-52-1170, dated September 5, 2016; or Airbus Service Bulletin A320-52-1171, Revision 02, dated April 10, 2017; specifies to contact Airbus for appropriate action, and specifies that action as ``RC'' (Required for Compliance): Before further flight, accomplish corrective actions in accordance with the procedures specified in paragraph (o)(2) of this AD.
Page 56163
(l) No Reporting Requirement
Although Airbus Service Bulletin A320-52-1171, Revision 02, dated April 10, 2017, specifies to submit certain information to the manufacturer, and specifies that action as ``RC,'' this AD does not include that requirement.
(m) Credit for Previous Actions
(1) This paragraph provides credit for the actions required by paragraphs (h) and (i) of this AD, if those actions were performed before the effective date of this AD using Airbus Service Bulletin A320-52-1171, dated October 29, 2015, provided that it can be conclusively determined that any part number D52371000018 was also inspected as specified in paragraph (h) of this AD.
