Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2008-22-
20, for certain Airbus Model A330-200, A330-300, and A340-300 series 
airplanes. AD 2008-22-20 currently requires repetitive high frequency 
eddy current (HFEC) inspections for cracking, repair if necessary, and 
modification of the upper shell structure of the fuselage. Since we 
issued AD 2008-22-20, we have determined from a fatigue and damage 
tolerance evaluation that the compliance times must be reduced. This 
proposed AD would shorten certain compliance times. We are proposing 
this AD to prevent fatigue cracking of the upper shell structure of the 
fuselage, which could result in reduced structural integrity of the 
airplane.

DATES: We must receive comments on this proposed AD by May 1, 2015.

Discussion

    On October 20, 2008, we issued AD 2008-22-20, Amendment 39-15717 
(73 FR 66747, November 12, 2008). AD 2008-22-20 requires actions 
intended to address an unsafe condition on certain Airbus Model A330-
200, A330-300, and A340-300 series airplanes.
    Since we issued AD 2008-22-20, Amendment 39-15717 (73 FR 66747, 
November 12, 2008), it has been determined from a fatigue and damage 
tolerance evaluation that the compliance times for certain inspections 
and modification must be reduced.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0012R1, dated January 24, 2014 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    During fatigue tests (EF3) on the A340-600, damage was found in 
the longitudinal doubler at the Vertical Tail Plane (VTP) attachment 
cut out between Frame (FR) 80 and FR86. This damage occurred between 
58,341 and 72,891 simulated flight cycles (FC).
    Due to the higher Design Service Goal and different design of 
the affected structural area (e.g., doubler thickness) for A330-200/
-300 and A340-300 airplane series, the damage assessment concluded 
that these airplanes may be also potentially affected.
    This condition, if not detected and corrected, could affect the 
structural integrity of the upper shell structure between FR80 and 
FR86.
    Prompted by these findings, EASA issued AD 2007-0284 [(http://ad.easa.europa.eu/blob/easa_ad_2007_0284_superseded.pdf/AD_2007-0284_1)] to require implementation of an inspection programme of 
this structural area using a high frequency eddy current (HFEC) 
method and a modification to improve the upper shell structure.
    Since that [EASA] AD was issued, in the frame of a new fatigue 
and damage tolerance evaluation, taking into account the airplane

[[Page 13800]]

utilisation, the inspection threshold and intervals have been 
reassessed and the conclusion was that the thresholds and intervals 
for inspection, as well as the threshold for modifying the airplane, 
must be reduced.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2007-0284, which is superseded and 
introduces redefined thresholds and intervals.
    This [EASA] AD is revised to clarify that, under some 
conditions, accomplishment of a repair constitutes terminating 
action for the repetitive inspections. One of the outcome of this 
clarification is the deletion of paragraph (5) of 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 it in Docket No. 
FAA-2015-0490.
    Initial compliance time thresholds range from 7,300 flight cycles 
or 47,600 flight hours, and up to 25,400 flight cycles or 76,300 flight 
hours, depending on configuration and range.
    Repetitive compliance time thresholds range from 1,700 flight 
cycles or 11,300 flight hours, and up to 4,500 flight cycles or 13,500 
flight hours, depending on configuration.

Widespread Fatigue Damage

    Structural fatigue damage is progressive. It begins as minute 
cracks, and those cracks grow under the action of repeated stresses. 
This can happen because of normal operational conditions and design 
attributes, or because of isolated situations or incidents such as 
material defects, poor fabrication quality, or corrosion pits, dings, 
or scratches. Fatigue damage can occur locally, in small areas or 
structural design details, or globally. Global fatigue damage is 
general degradation of large areas of structure with similar structural 
details and stress levels. Multiple-site damage is global damage that 
occurs in a large structural element such as a single rivet line of a 
lap splice joining two large skin panels. Global 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, in a condition known as 
widespread fatigue damage (WFD). 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.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information. The actions 
described in this service information are intended to correct the 
unsafe condition identified in the MCAI. This service information is 
reasonably available; see ADDRESSES for ways to access this service 
information.
     Airbus Service Bulletin A330-53-3159, Revision 02, dated 
March 29, 2010. The service information describes procedures for a 
modification of the fuselage, which includes inspections (e.g., eddy 
current rotating probe test of fastener holes for cracking, high 
frequency eddy current (HFEC) inspections for cracking of the upper 
shell structure of the fuselage, and checks of the fastener position 
for clearance) and applicable corrective actions (e.g., repair and 
rework).
     Airbus Service Bulletin A330-53-3160, Revision 03, dated 
January 6, 2012. The service information describes procedures for 
applicable actions, including an eddy current rotating probe test for 
cracking of the fastener holes and an HFEC inspection for cracks in the 
upper shell of the fuselage (and including checks of the fastener 
position for clearance and applicable corrective actions (e.g., repair 
and rework)), and a modification of the airplane upper shell structure 
of the fuselage between FR80 and FR86.
     Airbus Service Bulletin A330-53-3168, Revision 02, dated 
December 21, 2011. The service information describes procedures for a 
HFEC inspection for cracking of the upper shell structure of the 
fuselage between FR80 and FR86.
     Airbus Service Bulletin A340-53-4165, Revision 02, dated 
March 29, 2010. The service information describes procedures for a 
modification of the fuselage, which includes inspections (e.g., eddy 
current rotating probe test of fastener holes for cracking, HFEC 
inspections for cracking of the upper shell structure of the fuselage, 
and checks of the fastener position for clearance) and applicable 
corrective actions (e.g., repair and rework).
     Airbus Service Bulletin A340-53-4172, Revision 01, dated 
July 8, 2009. The service information describes procedures for 
inspections (e.g., rototest inspections of fastener holes for cracking, 
HFEC inspections for cracking of the upper shell structure of the 
fuselage, and checks of the fastener position for clearance) and 
modification of the airplane upper shell structure between FR80 and 
FR86 (including applicable corrective actions (e.g., repair and 
rework).
     Airbus Service Bulletin A340-53-4174, Revision 02, dated 
December 21, 2011. The service information describes procedures for a 
HFEC inspection for cracking of the upper shell structure of the 
fuselage between FR80 and FR86.

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.

[[Page 13801]]

Differences Between This Proposed AD and the MCAI or Service 
Information

    Unlike the procedures described in the service information, this 
proposed AD would not permit further flight if cracks are detected in 
the upper shell structure. We have determined that, because of the 
safety implications and consequences associated with that cracking, any 
cracked upper shell structure must be repaired before further flight. 
This difference has been coordinated with the EASA and Airbus.

Explanation of Compliance Time for Modification

    The compliance time for the modification specified in this proposed 
AD for addressing WFD was established to ensure that discrepant 
structure is modified 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 26 airplanes of U.S. 
registry. We also estimate that it would take about 208 work-hours per 
product to comply with the basic requirements (inspection and 
modification) of this proposed AD. The average labor rate is $85 per 
work-hour. Required parts would cost about $28,360 per product. Based 
on these figures, we estimate the cost of this proposed AD on U.S. 
operators to be $1,197,040, or $46,040 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.
    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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 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.
