Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A300 and A310 series airplanes, and certain Model A300 B4-
600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R 
Variant F airplanes (collectively called Model A300-600 series 
airplanes). This AD was prompted by a review of certain repairs, which 
revealed that the structural integrity of the airplane could be 
negatively affected if those repairs are not re-worked. This AD 
requires an inspection to identify certain repairs, and corrective 
action if necessary. We are issuing this AD to detect and correct 
certain repairs on the floor cross beams flange. If those repairs are 
not reworked, the structural integrity of the airplane could be 
negatively affected.

DATES: This AD becomes effective May 1, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of May 1, 2015.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all Airbus Model A300 and 
A310 series airplanes, and certain Model A300 B4-600, B4-600R, and F4-
600R series airplanes, and Model A300 C4-605R Variant F airplanes 
(collectively called Model A300-600 series airplanes). The NPRM 
published in the Federal Register on April 16, 2014 (79 FR 21413).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2013-0220, dated September 18, 2013 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model A300 
and A310 series airplanes, and certain Model A300 B4-600, B4-600R, and 
F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes 
(collectively called Model A300-600 series airplanes). The MCAI states:

    In the frame of the Extended Service Goal (ESG) activity, all 
existing Structural Repair Manual (SRM) repairs were reviewed.
    This analysis, which consisted in new static and fatigue 
calculations, revealed that some repairs were no longer applicable 
to some specific areas.
    These repairs, if not reworked, could affect the structural 
integrity of the aeroplane. To address the repairs on the floor 
cross beams flange, Airbus issued Alert Operator Transmission (AOT) 
A300-53A0392, AOT A300-53A6171 and AOT A310-53A2135.
    To address this unsafe condition, and further to the 
implementation of the Aging Aircraft Safety Rule (AASR), this [EASA] 
Airworthiness Directive requires a [general visual] inspection of 
the floor cross beams flange at frame (FR)11 and FR12A to identify 
SRM repairs and, depending on findings, accomplishment of corrective 
action [reworking the SRM repairs].

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0229-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (79 
FR 21413, April 16, 2014) and the FAA's response to each comment.

Request To Change the Compliance Time Expression From Months to Flight 
Cycles

    United Parcel Service (UPS) requested that the compliance time 
proposed in the NPRM (79 FR 21413, April 16, 2014) for doing the 
general visual inspection be changed from a compliance time based on 
months to a compliance time based on the accumulation of flight cycles 
since certain structural repair manual (SRM) repairs were incorporated 
on an airplane. UPS stated that all documentation related to the NPRM 
indicated that the reported damage is fatigue-related; therefore the 
inspection compliance time should reflect a typical fatigue-related 
issue, which is expressed in flight cycles. UPS explained that it did 
not provide a proposed compliance time because it did not have data and 
suggested that the original equipment manufacturer (OEM) could 
establish compliance times for the instructions for continued 
airworthiness based on the data used in the SRM repair evaluation to 
determine extended service goals.
    We do not agree to change the compliance time expression from 
months to accumulated flight cycles since certain SRM repairs were 
done. The OEM does not have documentation for all the SRM repairs 
accomplished on each airplane, thus it is unable to establish 
compliance times because of the incomplete data. The FAA and EASA have 
determined that a 30-month compliance time is sufficient to accomplish 
the inspection and all applicable corrective actions. No change has 
been made to this AD regarding this issue. However, under the 
provisions of paragraph (i) of this AD, we may approve requests for 
adjustments to the compliance time if data are submitted to 
substantiate that such an adjustment would provide an acceptable level 
of safety.

Request To Omit References to the AD in Repair Approvals

    UPS requested that paragraphs (h) and (i)(2) of the NPRM (79 FR 
21413, April 16, 2014) be revised to omit the statement ``[F]or a 
repair method to be approved, the repair approval must specifically 
refer to this AD.'' UPS stated that the FAA included this sentence in 
the NPRM because there is a ``potential'' for operators to do repairs 
that do not adequately address the unsafe condition. UPS commented that 
adding a reference to the applicable AD on repair documentation does 
not address the root cause of repair documentation availability. 
Previously approved repairs for an AD should have been vetted as part 
of the corrective action and AD development process. However, if a 
repair is not identified during that process, the operator is still 
responsible for adhering to the Airworthy Product provision in an AD. 
The Airworthy Product provision, in conjunction with FAA Advisory 
Circular 120-77, ``Maintenance and Alteration Data,'' dated October 7, 
2002 (http://rgl.faa.gov/Regulatory_and_Guidance_Library/
rgAdvisoryCircular.nsf/0/199e798c7ee4347786256c4d004ae5dc/$FILE/
AC%20120-77.pdf), provides sufficient guidance and clarification for 
repairs accomplished during compliance with the requirements of an AD.
    We concur with the commenter's request to remove from this AD the 
requirement that repair approvals specifically refer to this AD. Since 
late 2006, we have included a standard paragraph titled ``Airworthy 
Product'' in all MCAI ADs in which the FAA develops an AD based on a 
foreign authority's AD. The MCAI or referenced service information in 
an FAA AD often directs the owner/operator to contact the manufacturer 
for corrective actions, such as a repair. Briefly, the Airworthy 
Product paragraph allowed owners/operators to use corrective actions 
provided by the manufacturer if those actions were FAA approved. In 
addition, the paragraph stated that any actions approved by the State 
of Design Authority (or its delegated agent) are considered to be FAA 
approved.
    In the NPRM (79 FR 21413, April 16, 2014), we proposed to prevent 
the use

[[Page 16257]]

of repairs that were not specifically developed to correct the unsafe 
condition by requiring that the repair approval provided by the State 
of Design Authority or its delegated agent specifically refer to this 
FAA AD. This change was 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 proposed to change the phrase ``its delegated agent'' to 
include ``the Design Approval Holder (DAH) with a State of Design 
Authority's design organization approval (DOA)'' to refer to a DAH 
authorized to approve required repairs for the AD.
    Comments were provided to another NPRM (Directorate Identifier 
2012-NM-101-AD (79 FR 21413, April 16, 2014)) about these proposed 
changes. UPS commented on that NPRM as follows: ``The proposed wording, 
being specific to repairs, eliminates the interpretation that Airbus 
messages are acceptable for approving minor deviations (corrective 
actions) needed during accomplishment of an AD mandated Airbus service 
bulletin.''
    That comment has made the FAA aware that some operators have 
misunderstood or misinterpreted the Airworthy Product paragraph to 
allow the owner/operator to use messages provided by the manufacturer 
as approval of deviations during the accomplishment of an AD-mandated 
action. The Airworthy Product paragraph does not approve messages or 
other information provided by the manufacturer for deviations to the 
requirements of the AD-mandated actions. The Airworthy Product 
paragraph only addresses the requirement to contact the manufacturer 
for corrective actions for the identified unsafe condition and does not 
cover deviations from other AD requirements. However, deviations to AD-
required actions are addressed in 14 CFR 39.17, and anyone may request 
approval of an alternative method of compliance to the AD-required 
actions using the procedures found in 14 CFR 39.19.
    To address this misunderstanding and misinterpretation of the 
Airworthy Product paragraph, we have changed that paragraph and 
retitled it ``Contacting the Manufacturer.'' This paragraph now 
clarifies that for any requirement in this AD to obtain corrective 
actions from a manufacturer, the actions must be accomplished using a 
method approved by the FAA, or the European Aviation Safety Agency 
(EASA), or Airbus's EASA Design Organization Approval (DOA).
    The Contacting the Manufacturer paragraph also clarifies that, if 
approved by the DOA, the approval must include the DOA-authorized 
signature. The DOA signature indicates that the data and information 
contained in the document are EASA approved, which is also FAA 
approved. Messages and other information provided by the manufacturer 
that do not contain the DOA-authorized signature approval are not EASA 
approved, unless EASA directly approves the manufacturer's message or 
other information.
    This clarification does not remove flexibility afforded previously 
by the Airworthy Product paragraph. Consistent with long-standing FAA 
policy, such flexibility was never intended for required actions. This 
is also consistent with the recommendation of the AD Implementation 
Aviation Rulemaking Committee to increase flexibility in complying with 
ADs by identifying those actions in manufacturers' service instructions 
that are ``Required for Compliance'' with ADs. We continue to work with 
manufacturers to implement this recommendation. But once we determine 
that an action is required, any deviation from the requirement must be 
approved as an alternative method of compliance.
    Other commenters pointed out that in many cases the foreign 
manufacturer's service bulletin and the foreign authority's MCAI may 
have been issued some time before the FAA AD. Therefore, the DOA may 
have provided U.S. operators with an approved repair, developed with 
full awareness of the unsafe condition, before the FAA AD is issued. 
Under these circumstances, to comply with the FAA AD, the operator 
would be required to go back to the manufacturer's DOA and obtain a new 
approval document, adding time and expense to the compliance process 
with no safety benefit.
    Based on these comments, we removed the requirement from this AD 
that the DAH-provided repair specifically refer to this AD. Before 
adopting such a requirement in the future, the FAA will coordinate with 
affected DAHs and verify they are prepared to implement means to ensure 
that their repair approvals consider the unsafe condition addressed in 
an AD. Any such requirements will be adopted through the normal AD 
rulemaking process, including notice-and-comment procedures, when 
appropriate.
    We have also decided not to include a generic reference to either 
the ``delegated agent'' or the ``DAH with State of Design Authority 
design organization approval,'' but instead we will provide the 
specific delegation approval granted by the State of Design Authority 
for the DAH.

Additional Changes to This AD

    In this AD, we have corrected a formatting error in the 
subparagraphs of paragraph (g)(1) of the NPRM (79 FR 21413, April 16, 
2014). The subparagraphs were incorrectly identified as (g)(1)(a), 
(g)(1)(b), and (g)(1)(c), and should have been identified as paragraphs 
(g)(1)(i), (g)(1)(ii), and (g)(1)(iii) of this AD.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 21413, April 16, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 21413, April 16, 2014).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information, which 
describes procedures for doing general visual inspections of the floor 
cross beams flange at certain frames and contacting the manufacturer 
for corrective actions:
     Airbus All Operator Telex A300-53A0392, dated March 14, 
2012 (for Model A300 series airplanes);
     Airbus All Operator Telex A300-53A617, dated March 14, 
2012 (for Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes; 
Model A300 B4-605R and B4-622R airplanes; Model A300 F4-605R and F4-
622R airplanes; and Model A300 C4-605R Variant F airplanes); and
     Airbus All Operator Telex A310-53A2135, dated March 14, 
2012 (for Model A310 series airplanes).
    This service information is reasonably available; see ADDRESSES for 
ways to access this service information.

Costs of Compliance

    We estimate that this AD affects 177 airplanes of U.S. registry.
    We also estimate that it would take about 1 work-hour per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85

[[Page 16258]]

per work-hour. Based on these figures, we estimate the cost of this AD 
on U.S. operators to be $15,045, or $85 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this 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.

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.
