Airworthiness Directives; Airbus Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede Airworthiness Directive (AD) 2015-15-
13, which applies 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. AD 2015-
15-13 requires modification of the potable water service panel and waste water service panel, including doing applicable related investigative and corrective actions. Since we issued AD 2015-15-13, further investigations linked to widespread fatigue damage (WFD) analysis highlighted that, to meet the WFD requirements, it is necessary that the affected modification not be accomplished before reaching a certain threshold. This proposed AD would require modification of the waste water and potable water service panels with new compliance times. This proposed AD would also remove certain airplanes from the applicability and add Model A320-216 airplanes to the applicability. We are proposing this AD to address the unsafe condition on these products.

Discussion
Fatigue damage can occur locally, in small areas or structural design details, or globally, in widespread areas. Multiple-site damage is widespread damage that occurs in a large structural element such as a single rivet line of a lap splice joining two large skin panels. Widespread damage can also occur in multiple elements such as adjacent frames or stringers. Multiple-site damage and multiple-element damage cracks are typically too small initially to be reliably detected with normal inspection methods. Without intervention, these cracks will grow, and eventually compromise the structural integrity of the airplane. This condition is known as WFD. It is associated with general degradation of large areas of structure with similar structural details and stress levels. As an airplane ages, WFD will likely occur, and will certainly occur if the airplane is operated long enough without any intervention.
The FAA's WFD final rule (75 FR 69746, November 15, 2010) became effective on January 14, 2011. The WFD rule requires certain actions to prevent structural failure due to WFD throughout the operational life of certain existing transport category airplanes and all of these airplanes that will be certificated in the future. For existing and future airplanes subject to the WFD rule, the rule requires that DAHs establish a limit of validity (LOV) of the engineering data that support the structural maintenance program. Operators affected by the WFD rule may not fly an airplane beyond its LOV, unless an extended LOV is approved.
The WFD rule (75 FR 69746, November 15, 2010) does not require identifying and developing maintenance actions if the DAHs can show that such actions are not necessary to prevent WFD before the airplane reaches the LOV. Many LOVs, however, do depend on accomplishment of future maintenance actions. As stated in the WFD rule, any maintenance actions necessary to reach the LOV will be mandated by airworthiness directives through separate rulemaking actions.
In the context of WFD, this action is necessary to enable DAHs to propose LOVs that allow operators the longest operational lives for their airplanes, and still ensure that WFD will not occur. This approach allows for an implementation strategy that provides flexibility to DAHs in determining the timing of service information development (with FAA approval), while providing operators with certainty regarding the LOV applicable to their airplanes.
We issued AD 2015-15-13, Amendment 39-18223 (80 FR 45857, August 3, 2015) (``AD 2015-15-13''), for certain Airbus Model A319 series airplanes; Model A320-211, -212, -214, -231,-232, and -233 airplanes; and Model A321 series airplanes. AD 2015-15-13 was prompted by reports of cracks that could be initiated at the waste water service panel area and the potable water service panel area. AD 2015-15-13 requires modification of the potable water service panel and waste water service panel, including doing applicable related investigative and corrective actions. We issued AD 2015-15-13 to prevent any cracking at the waste water service panel area and the potable water service panel area, which could affect the structural integrity of the airplane.
Since we issued AD 2015-15-13, further investigations linked to WFD analysis highlighted that, to meet the WFD requirements, it is necessary that the affected modification is not accomplished before reaching a certain threshold by imposing a ``window of embodiment.''
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2017-0098, dated June 7, 2017 (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; Airbus Model A320-211, -212, -214, -216, -231, -
232, and -233 airplanes; and Airbus Model A321-111, -112, -131, -211, -
212, -213, -231, and -232 airplanes. The MCAI states:
During the full scale fatigue test on A320-200, it was noticed that, due to fatigue, cracks could initiate at the potable water and waste water service panel areas.
This condition, if not detected and corrected, could affect the structural integrity of the aeroplane.
Prompted by these findings, Airworthiness Limitation Section (ALS) Part 2 tasks were introduced for the affected aeroplanes. Since those actions were taken, Airbus developed production mod 160055 and mod 160056 to embody reinforcements (cold working on certain rivet rows) of the potable water and waste water service panels, and published associated Airbus Service Bulletin (SB) A320-
53-1272 and Airbus SB A320-53-1267 for in-service embodiment. Complementary design office studies highlighted that the ``Sharklets'' installation on certain aeroplanes has a significant impact on the aeroplane structure (particularly, A319 and A320 post-
mod 160001, A320 post-SB A320-57-1193 (mod 160080), and A321 post-
mod 160021), leading to different compliance times, depending on aeroplane configuration.
Consequently, EASA issued AD 2014-0081 which corresponds to FAA AD 2015-15-13 to require reinforcement of the potable water and waste water service panels. Accomplishment of these modifications cancelled the need for the related ALS Part 2 Tasks.
Since that AD was issued, further investigations linked to the Widespread Fatigue Damage (WFD) analysis highlighted that, to meet the WFD requirements, it is necessary that the affected modification is not accomplished before reaching a certain threshold, by imposing a so-called ``window of embodiment''. Consequently, Airbus revised SB A320-53-1272 (now at revision (Rev.) 04) and SB A320-53-1267 (now at Rev. 05).
For the reasons described above, this EASA AD retains the requirements of EASA AD 2014-0081, which is superseded, and introduces additional compliance times for those actions.
This proposed AD would also remove Model A319 series airplanes on which modification 28162, 28238, and 28342 have been embodied (``Corporate Jet'' modifications) from the applicability because production modifications
Page 58774
mitigated the risk associated with the unsafe condition. This proposed AD would also add Model A320-216 airplanes to the applicability because those airplanes are affected by the identified unsafe condition.

1100.
Related Service Information Under 1 CFR Part 51
Airbus has issued Service Bulletin A320-53-1267, Revision 05, dated November 29, 2016, which describes procedures for modifying the waste water service panel. Airbus has also issued Service Bulletin A320-53-
1272, Revision 04, dated November 29, 2016, which describes procedures for modifying the potable water service panel. Both modifications include a check of the diameter of the holes of removed fasteners, a related investigative action (rotating probe inspection for cracking on the holes of the removed fasteners) and a corrective action (repair). 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.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design.
Explanation of Compliance Time
The compliance time for the replacement specified in this proposed AD for addressing WFD was established to ensure that discrepant structure is replaced before WFD develops in airplanes. Standard inspection techniques cannot be relied on to detect WFD before it becomes a hazard to flight. We will not grant any extensions of the compliance time to complete any AD-mandated service bulletin related to WFD without extensive new data that would substantiate and clearly warrant such an extension.
Costs of Compliance
We estimate that this proposed AD affects 851 airplanes of U.S. registry.
We also estimate that it would take about 27 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $700 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $2,548,745, or $2,995 per product.
We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:
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
