RIN 2120-AA64

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede airworthiness directive (AD) 2005-23-
08 that applies to certain Airbus Model A300 B4-605R and B4-622R 
airplanes; Model A300 F4-605R airplanes; and Model A300 C4-605R Variant 
F airplanes. AD 2005-23-08 required repetitive inspections to detect 
cracks of certain attachment holes, installation of new fasteners, 
follow-on inspections or repair if necessary, and modification of the 
angle fittings of fuselage frame FR47. Since we issued AD 2005-23-08, 
we have received reports of cracks found on the horizontal flange of 
the Frame 47 internal corner angle fitting while accomplishing the 
modification required by AD 2005-23-08. This proposed AD would add new 
repetitive ultrasonic inspections for cracks of the center wing box 
lower panel; and repair if necessary. This proposed AD also removes 
certain airplanes from the applicability. We are proposing this AD to 
detect and correct fatigue cracking of

[[Page 78286]]

the forward fitting of fuselage frame FR47, which could result in 
reduced structural integrity of the frame.

Discussion

    On October 31, 2005, we issued AD 2005-23-08, Amendment 39-14366 
(70 FR 69056, November 14, 2005). That AD required actions intended to 
address an unsafe condition on certain Model A300 B4-601, B4-603, B4-
620, and B4-622 airplanes; Model A300 B4-605R and B4-622R airplanes; 
Model A300 F4-605R airplanes; and Model A300 C4-605R Variant F 
airplanes.
    Since we issued AD 2005-23-08, Amendment 39-14366 (70 FR 69056, 
November 14, 2005), the European Aviation Safety Agency (EASA), which 
is the Technical Agent for the Member States of the European Community, 
has issued EASA Airworthiness Directive 2012-0092, dated May 25, 2012; 
correction dated June 4, 2012 (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:

    Prompted by cracks found on the Frame 47 angle fitting, DGAC 
France published AD 2000-533-328 [(http://ad.easa.europa.eu/ad/F-2000-533-328R1)] to require [a] repetitive inspection programme for 
fuselage frame 47. If not detected and corrected, these cracks could 
affect the structural integrity of the Centre Wing Box (CWB) of the 
aeroplane.
    Subsequent to the publication of a new repetitive inspection 
programme for fuselage frame 47 at certain fasteners of the CWB 
angle fitting, DGAC France issued AD F-2004-159 [(http://ad.easa.europa.eu/ad/F-2004-159)] [which corresponds to AD 2005-23-
08, Amendment 39-14366 (70 FR 69056, November 14, 2005)], 
superseding AD 2000-533-328.
    After DGAC France AD F-2004-159 was issued, cracks were 
reportedly found on the horizontal flange of the Frame 47 internal 
corner angle fitting during accomplishment of routine maintenance 
structural inspection and modification in accordance with Airbus SB 
A300-57-6050.
    Prompted by these findings, Airbus reviewed and amended the 
inspection programme for the internal lower angle fitting flange 
(horizontal face). The inspection programme for the lower angle 
fitting web (vertical face) related to SB A300-57-6049 and internal 
lower angle fitting modification programme related to SB A300-57-
6050 remain unchanged.
    For the reasons explained above, this new [EASA] AD retains the 
requirements of DGAC France AD F-2004-159, which is superseded, and 
requires additional repetitive [ultrasonic] inspections [for cracks] 
of the CWB lower panel through the ultrasonic method and, depending 
on findings, [repair, e.g.,] re-installation of removed fasteners in 
transition fit instead of interference.
    This [EASA] AD has been republished to correct a typographical 
error * * *.

    The repetitive interval for the new ultrasonic inspection is either 
1,260 flight cycles or 2,720 flight hours, whichever occurs first; or 
1,360 flight cycles or 2,200 flight hours, whichever occurs first; 
depending on average flight time of the airplane. You may obtain 
further information by examining the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletins A300-57-6049, 
Revision 07, dated December 22, 2006, and A300-57-6086, Revision 05, 
dated January 30, 2012. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

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.

Difference Between This Proposed AD and the MCAI or Service Information

    Although the MCAI and service information specify to contact the 
manufacturer for instructions to repair certain conditions, this 
proposed AD would require repairing those conditions using a method 
approved by the Manager, International Branch, ANM-116, Transport 
Airplane Directorate, FAA; or the EASA (or its delegated agent; or the 
Design Approval Holder with EASA's design organization approval), as 
applicable.

[[Page 78287]]

Explanation of Changes to AD 2005-23-08, Amendment 39-14366 (70 FR 
69056, November 14, 2005)

    In many FAA transport ADs, when the service information specifies 
to contact the manufacturer for further instructions if certain 
discrepancies are found, we typically include in the AD a requirement 
to accomplish the action using a method approved by either the FAA or 
the State of Design Authority (or its delegated agent).
    We have recently been notified that certain laws in other countries 
do not allow such delegation of authority, but some countries do 
recognize design approval organizations. In addition, we have become 
aware that some U.S. operators have used repair instructions that were 
previously approved by a State of Design Authority or a Design Approval 
Holder (DAH) as a method of compliance with this provision in FAA ADs. 
Frequently, in these cases, the previously approved repair instructions 
come from the airplane structural repair manual or the DAH repair 
approval statements that were not specifically developed to address the 
unsafe condition corrected by the AD. Using repair instructions that 
were not specifically approved for a particular AD creates the 
potential for doing repairs that were not developed to address the 
unsafe condition identified by the MCAI AD, the FAA AD, or the 
applicable service information, which could result in the unsafe 
condition not being fully corrected.
    To prevent the use of repairs that were not specifically developed 
to correct the unsafe condition, this proposed AD would require that 
the repair approval specifically refer to the FAA AD. This change is 
intended to clarify the method of compliance and to provide operators 
with better visibility of repairs that are specifically developed and 
approved to correct the unsafe condition. In addition, we use the 
phrase ``its delegated agent, or by the DAH with State of Design 
Authority design organization approval, as applicable'' in this 
proposed AD to refer to an DAH authorized to approve required repairs 
for this proposed AD.

Explanation of Change to Applicability

    AD 2005-23-08, Amendment 39-14366 (70 FR 69056, November 14, 2005), 
includes Airbus Model A300 B4-601 airplanes in the applicability. 
However, this proposed AD does not include Model A300 B4-601 airplanes 
because these airplanes are no longer in service.

Costs of Compliance

    We estimate that this proposed AD affects about 65 products of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave., SW., Washington, DC 20591. ATTN: Information 
Collection Clearance Officer, AES-200.

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);

[[Page 78288]]

    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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

List of Subjects in 14 CFR Part 39
