Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2018-12-08, 
which applied to certain Airbus SAS Model A330-200 and -300 series 
airplanes, and Model A340-212, -213, -312, and -313 airplanes. AD 2018-
12-08 required repetitive inspections of certain fastener holes, and 
related investigative and corrective actions if necessary. This new AD 
corrects certain compliance time references. This AD was prompted by a 
report of cracking at fastener holes located at a certain frame (FR) on 
the lower shell panel junction. We are issuing this AD to address the 
unsafe condition on these products.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued AD 2018-12-08, Amendment 39-19312 (83 FR 33821, July 18, 
2018) (``AD 2018-12-08''), which applied to certain Airbus SAS Model 
A330-200 and -300 series airplanes, and Model A340-212, -213, -312, and 
-313 airplanes. AD 2018-12-08 was prompted by a report of cracking at 
fastener holes located at FR40 on the lower shell panel junction. AD 
2018-12-08 required repetitive inspections of certain fastener holes, 
and related investigative and corrective actions if necessary. We 
issued AD 2018-12-08 to address cracking at FR40 on the lower shell 
panel junction; such cracking could lead to reduced structural 
integrity of the fuselage.
    Since we issued AD 2018-12-08, we have determined that it is 
necessary to correct certain service bulletin table references, which 
provide the compliance times for the initial inspection. Table 1 to 
paragraph (g)(1) of AD 2018-12-08 pointed to ``table 1'' of the service 
information for the initial compliance time. However, table 2 and table 
3 in the service bulletins also apply to certain airplanes (those in 
Configuration 1). All airplanes belonging to affected U.S. operators 
are in Configuration 2 or Configuration 3, which use only table 1 in 
the service bulletins. This AD corrects the service bulletin table 
references for the compliance times. We have changed table 1 to 
paragraph (g)(1) of this AD by removing the limitation to ``table 1'' 
of the service bulletins, and instead referring to the compliance times 
in ``paragraph 1.E., `Compliance,' '' of the service bulletins.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0063, dated April 12, 2017 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Airbus SAS Model A330-200, 
A330-300, and A340-200 series airplanes, and Model A340-312 and -313 
airplanes. The MCAI states:

    During full scale fatigue test of the Frame (FR) 40 to fuselage 
skin panel junction, fatigue damage was found. Corrective actions 
consisted of in-service installation of an internal reinforcing 
strap on the related junction, as currently required by DGAC 
[Direction G[eacute]n[eacute]rale de l'Aviation Civile] France AD 
1999-448-126(B), which refers to Airbus Service Bulletin (SB) A340-
53-4104 Revision 02, and [DGAC] AD 2001-070(B), which refers to 
Airbus SB A330-53-3093 Revision 04; retrofit improvement of internal 
reinforcing strap fatigue life through recommended Airbus SB A330-
53-3145; and introducing a design improvement in production through 
Airbus mod 44360.
    After those actions were implemented, cracks were found on both 
left-hand (LH) and right-hand (RH) sides on internal strap, butt 
strap, keel beam fitting, or forward fitting FR40 flange. These 
findings were made during embodiment of a FR40 web repair on an A330 
aeroplane, and during keel beam replacement on an A340 aeroplane, 
where the internal strap was removed and a special detailed 
inspection (SDI) was performed on several holes.
    This condition, if not detected and corrected, could affect the 
structural integrity of the centre fuselage of the aeroplane.
    Prompted by these findings, Airbus issued SB A330-53-3215 and SB 
A340-53-4215, providing inspection instructions. Consequently, EASA 
issued AD 2014-0136 [which corresponds to FAA AD 2017-07-07, 
Amendment 39-18845 (82 FR 18547, April 20, 2017) (``AD 2017-07-
07'')] to require repetitive SDI (rototest) of 10 fastener holes 
located at the FR40 lower shell panel junction on both LH and RH 
sides and, depending on findings, accomplishment of applicable 
corrective action(s).
    Since that [EASA] AD was issued, prompted by the results of 
complementary fatigue analyses, it was determined that postmod 55792 
aeroplanes could be also affected by crack initiation and 
propagation at this area of the fuselage. These analyses 
demonstrated that post-mod 55792 aeroplanes must follow the same 
maintenance program as aeroplanes in postmod 55306 and pre-mod 55792 
configuration. Consequently, Airbus published SB A330-53-3215 
Revision 02 and SB A340-53-4215 Revision 02 to expand the 
Effectivity accordingly.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2014-0136, which is superseded, which now 
also apply to aeroplanes in post-mod 55792 configuration [the 
applicability identifies airplanes in post-mod 44360 configuration].

    AD 2017-07-07 included Model A340-211 airplanes in its 
applicability. Airbus SAS Model A340-211 airplanes are not identified 
in the applicability of this AD because those airplanes are not 
affected by the identified unsafe condition. All of those airplanes are 
in the pre-Airbus SAS modification 44360 configuration. The MCAI also 
does not include Model A340-211 airplanes in its applicability.
    The compliance time ranges between 20,000 flight cycles or 65,400 
flight hours and 20,800 flight cycles or 68,300 flight hours, depending 
on airplane utilization and configuration. The repetitive inspection 
interval ranges between 14,000 flight cycles or 95,200 flight hours and 
24,600 flight cycles or 98,700 flight hours, depending on airplane 
utilization and configuration.
    You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0789.

Related Service Information Under 1 CFR Part 51

    Airbus SAS has issued Service Bulletin A330-53-3215, Revision 03, 
dated January 22, 2018; and Service Bulletin A340-53-4215, Revision 02, 
dated November 23, 2016. This service information describes procedures 
for repetitive rototest inspections of certain fastener holes, and 
related investigative and corrective actions if necessary. These 
documents are distinct since they apply to different airplane models. 
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 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

[[Page 45552]]

MCAI and service information referenced above. We are issuing this AD 
because we evaluated all pertinent information and determined the 
unsafe condition exists and is likely to exist or develop on other 
products of the same type design.

FAA's Justification and Determination of the Effective Date

    This AD corrects an error that affects compliance for non-U.S.-
registered airplanes only. Therefore, we find good cause that notice 
and opportunity for prior public comment are unnecessary. In addition, 
for the reason stated above, we find that good cause exists for making 
this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2018-0789; Product 
Identifier 2018-NM-120-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 99 airplanes of U.S. registry. 
This AD adds no new economic burden. The current costs for this AD are 
repeated for the convenience of affected operators, as follows:

                                      Estimated Costs for Required Actions

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

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

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 and 
associated appliances 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.

the person identified in paragraph (l)(2) of this AD. Information 
may be emailed to [email protected]. Before using any 
approved AMOC, notify your appropriate principal inspector, or 
lacking a principal inspector, the manager of the local flight 
standards district office/certificate holding district office.
    (2) Contacting the Manufacturer: As of the effective date of 
this AD, for any requirement in this AD to obtain corrective actions 
from a manufacturer, the action must be accomplished using a method 
approved by the Manager, International Section, Transport Standards 
Branch, FAA; or EASA; or Airbus SAS's EASA DOA. If approved by the 
DOA, the approval must include the DOA-authorized signature.
    (3) Required for Compliance (RC): Except as specified by 
paragraphs (g)(1), (g)(2), (h)(1), (h)(2), and (i) of this AD: If 
any service information contains procedures or tests that are 
identified as RC, those procedures and tests must be done to comply 
with this AD; any procedures or tests that are not identified as RC 
are recommended. Those procedures and tests that are not identified 
as RC may be deviated from using accepted methods in accordance with 
the operator's maintenance or inspection program without obtaining 
approval of an AMOC, provided the procedures and tests identified as 
RC can be done and the airplane can be put back in an airworthy 
condition. Any substitutions or changes to procedures or tests 
identified as RC require approval of an AMOC.
