Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2016-12-
09, for certain Airbus Model A330-200, -200 Freighter, and -300 series 
airplanes; and Model A340-200 and -300 series airplanes. AD 2016-12-09 
requires removing fasteners, doing a rototest inspection of fastener 
holes, installing new fasteners, oversizing the holes and doing 
rototest inspections for cracks if necessary, and repairing any 
cracking that was found. Since we issued AD 2016-12-09, an evaluation 
by the design approval holder (DAH) indicates that certain fastener 
holes are subject to widespread fatigue damage (WFD). This proposed AD 
would add airplanes to the effectivity, add repetitive inspections of 
the fastener holes at frame (FR) 40, and, for certain airplanes, 
require a modification, which terminates the inspections. We are 
proposing this AD to address the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by April 12, 2018.

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 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 2016-12-09, Amendment 39-18558 (81 FR 38573, June 14, 
2016) (``AD 2016-12-09''), for certain Airbus Model A330-200, -200 
Freighter, and -300 series airplanes, and Model A340-200 and -300 
series airplanes. AD 2016-12-09 was prompted by reports that cracks 
were found on an adjacent hole of certain frames of the center wing box 
(CWB). AD 2016-12-09 requires removing fasteners, doing a rototest 
inspection of fastener holes, installing new fasteners, oversizing the 
holes and doing rototest inspections for cracks if necessary, and 
repairing any cracking that was found. We issued AD 2016-12-09 to 
detect and correct cracking on certain holes of the CWB, which could 
affect the structural integrity of the airplane.

Actions Since AD 2016-12-09 Was Issued

    Since we issued AD 2016-12-09, an evaluation by the DAH indicates 
that the fastener holes at FR40 of the inside and outside CWB (above 
and below bottom skin) are subject to WFD.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0069, dated April 25, 2017 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Airbus Model A330-200, -200 
Freighter, and -300 series airplanes, and Model A340-200 and -300 
series airplanes. The MCAI states:

    During accomplishment of A330 Airworthiness Limitation Item 
(ALI) task 57-11-04 on the rear fitting of the Frame (FR) 40 between 
stringers (STR) 38 and STR39 on both LH [left-hand] and RH [right-
hand] sides of the fuselage, cracks were found on an adjacent hole. 
After reaming at second oversize of the subject hole, the crack was 
still present. As a result of a sampling inspection program, 
additional crack findings were reported on this adjacent hole on 
other A330 and A340 aeroplanes.
    This condition, if not detected and corrected, could affect the 
structural integrity of the centre fuselage of the aeroplane.
    Prompted by these findings, EASA issued AD 2014-0149 [which 
corresponds to FAA AD 2016-12-09] to require removal of the 
fasteners and repetitive Special Detailed Inspection (SDI) of 
fastener holes at FR40 vertical web above or below Centre Wing Box 
(CWB) lower panel reference on both LH and RH sides of the fuselage, 
and, depending on findings, accomplishment of the applicable 
corrective actions. That [EASA] AD excluded certain aeroplanes from 
the Applicability, on which Airbus modification (mod) 55792 or mod 
55306 had been embodied in production.
    Since EASA AD 2014-0149 was issued, prompted by complementary 
fatigue analyses correlated with in-service findings, Airbus 
published Service Bulletin (SB) A330-57-3115 Revision 01 and SB 
A340-57-4124 Revision 02, which introduced revised thresholds and 
intervals for the repetitive inspections of the inside CWB (above 
bottom skin), and an alleviation of the number of holes to be 
inspected, for post-mod 44360 and pre-mod 55306 configuration 
aeroplanes.
    In addition, for aeroplanes in post-mod 44360, post-mod 55306 
and pre-mod 205225 configuration, Airbus developed mod 206051, 
introducing reinforcement of the structural integrity of the inside 
CWB (above bottom skin) area, and published associated Airbus SB 
A330-57-3129 and SB A340-57-4136, as applicable, which avoids the 
need for required repetitive inspections for the inside of the CWB.
    Finally, Airbus published SB A330-57-3116 Revision 01 and SB 
A330-57-4125 Revision 01, as applicable, to expand their Effectivity 
to include aeroplanes in post-mod 44360 and post-mod 49202 
configuration for inspections of the outside CWB (below bottom 
skin), and introduced revised thresholds and intervals for the 
repetitive inspections of the outside CWB, and to provide an 
alleviation of the number of holes to be inspected. The repetitive 
inspection program for aeroplanes in pre-mod 44360 configuration 
remains unchanged.
    For the reasons described above, this [EASA] AD partially 
retains the requirements of EASA AD 2014-0149, which is superseded, 
and requires new repetitive inspections of the fastener holes at 
FR40 of the inside and the outside CWB (above and below bottom 
skin), and the implementation of the modification of the inside CWB, 
as terminating action of the repetitive SDI.

    Required actions also include oversizing certain holes, installing 
new fasteners, and repairing any cracking that is found.
    The compliance times for the inspections range depending on 
airplane operation and utilization. The earliest initial flight-cycle 
compliance time is 13,500 flight cycles. The earliest initial flight-
hour compliance time is 57,000 flight hours. The latest initial flight-
cycle compliance time is 30,900 flight cycles. The latest initial 
flight-hour compliance time is 162,000 flight hours. The earliest 
repetitive flight-cycle compliance time is 5,950 flight cycles. The 
earliest repetitive flight-hour compliance time is 24,300 flight hours. 
The latest repetitive flight-cycle compliance time is 7,400 flight 
cycles. The latest repetitive flight-hour compliance time is 40,400 
flight hours. You may examine the MCAI in the AD docket on the internet

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 these 
same type designs.

Explanation of a Certain 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 99 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

    We estimate the following costs to do any necessary on-condition 
actions that would be required based on the results of the proposed 
inspection. We have no way of determining the number of aircraft that 
might need these actions:

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition repairs 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

[[Page 8204]]

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 proposed 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.

introductory text of paragraph (j) of this AD: Before further 
flight, repair using a method approved by the Manager, International 
Section, Transport Standards Branch, FAA; or EASA; or Airbus's EASA 
DOA. If approved by the DOA, the approval must include the DOA-
authorized signature.

(k) No Reporting Required

    Although the applicable service information specified in 
paragraph (g)(1) of this AD specifies to submit certain information 
to the manufacturer, and specifies that action as ``RC'' (Required 
for Compliance), this AD does not include that requirement.

(l) Exceptions to Service Information

    (1) Where the applicable service information identified in 
paragraphs (g) and (m) of this AD specifies contacting Airbus for 
appropriate action: Before further flight, repair using a method 
approved by the Manager, International Section, Transport Standards

the approval must include the DOA-authorized signature.
    (2) Where paragraph 1.E., ``Compliance,'' of the applicable 
service information specified in paragraph (g)(1) of this AD 
specifies a compliance time in terms of a ``Threshold'' and ``Grace 
Period,'' this AD requires compliance at the later of the applicable 
threshold and grace period.
    (3) When it is determined that no RDAS is found to exist for the 
FR40 area it is acceptable to accomplish the first SDI before 
exceeding the applicable threshold, instead of ``before next 
flight'', as specified in the applicable service information 
specified in paragraph (g)(1)(ii), (g)(1)(iii), (g)(1)(v) and 
(g)(1)(vi) of this AD.

(m) Modification for Airplanes in Post-Modification 55306 and Pre-
