Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Airbus Model A330-200 and -300 series airplanes; and Model 
A340-200 and -300 series airplanes. This proposed AD was prompted by a 
determination that the compliance times for certain post-repair 
inspections and certain allowable damage limits (ADLs) must be reduced 
in order to address fatigue. This proposed AD would require identifying 
any repairs and ADLs used to assess or control any structural damage on 
certain structural areas, and corrective action if necessary. We are 
proposing this AD to prevent fatigue damage on primary structure and 
structural repairs, which could result in reduced structural integrity 
of the airplane.

DATES: We must receive comments on this proposed AD by April 4, 2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2015-0101R1, dated June 12, 2015 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Airbus Model A330-200 and -300 
series airplanes; and Model A340-200 and -300 series airplanes. The 
MCAI states:

    Result of a fleet survey accomplished in 2008 identified that 
the nature of flight missions of A330 and A340-200/300 fleets had 
significantly changed in comparison with assumed usage during the 
type certification. Consequently, it was decided to recalculate the 
Structural Repair Manual (SRM) fatigue values to ensure that the 
given threshold and intervals remain valid.
    The results of this recalculation identified reduced thresholds 
and intervals applicable for repairs and Allowable Damage Limits 
(ADL) affecting the following areas:

--Door cut-out corners of door surrounding panels (forward cargo 
door, forward passenger (PAX) door, mid PAX door, emergency exit 
door/PAX door 3, aft cargo door, bulk cargo door, aft PAX door), on 
both Left Hand (LH) and Right Hand (RH) sides,
--Stringer (STGR) 9 junction between Frame (FR) 10 and FR13 on both 
LH and RH sides, and
--Fuselage skin doubler repairs on both LH and RH sides.

    Failing to apply the reduced thresholds and intervals, could 
adversely affect the structural integrity of the aeroplane.
    To address this unsafe condition, Airbus issued SRM revision 
dated April 2013 and temporary revision (TR) 53-001 for the STGR9 
junction between FR10 and FR13 area (and subsequent revisions) to 
introduce reduced thresholds and intervals for the affected ADLs and 
repairs and issued a set of Service Bulletins (SB) to identify the 
ADLs used and repairs made, as well as to enable operators to update 
aeroplane repair records.
    Consequently EASA issued AD * * *, to require identification of 
any repairs and/or ADL used to assess or control any structural 
damage on certain structural areas and, depending on findings, 
accomplishment of corrective action(s) [including revising the 
maintenance or inspection program as applicable to incorporate 
revised thresholds and intervals and repair].
    Since that [EASA] AD was issued, data review confirmed that A330 
freighter versions are not affected by the unsafe condition.
    This [EASA] AD is revised to remove A330-223F and A330-243F from 
the Applicability.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
0465.

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.

Costs of Compliance

    We estimate that this proposed AD affects 95 airplanes of U.S. 
registry. We also estimate that it would take about 2 work-hours per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour. Based on these figures, we 
estimate the cost of this proposed AD on U.S. operators to be $16,150, 
or $170 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.

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

[[Page 8162]]

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.

(h) Corrective Actions

    If, during any review required by paragraph (g) of this AD, it 
is determined that an SRM ADL was used on an area specified in table 
2 to paragraph (g) of this AD to assess or control any structural 
damage, or any structural repair of an area specified in table 2 to 
paragraph (g) of this AD was accomplished as specified in the 
instructions of the applicable SRM revision, dated before April 2013 
or SRM temporary revision (TR) dated before November 28, 2014: 
Within the applicable compliance time specified in table 1 to 
paragraph (g) of this AD, do the actions specified in paragraph 
(h)(1) or (h)(2) of this AD, as applicable.
    (1) Revise the maintenance or inspection program, as applicable, 
with the applicable revised thresholds and intervals for the 
identified structural repairs embodied on the airplane, and 
accomplish all updated inspections, in accordance with the 
Accomplishment Instructions of the applicable service information 
identified in table 2 to paragraph (g) of this AD, except as 
required by paragraphs (h)(1)(i) and (h)(1)(ii) of this AD.
    (i) Where the applicable Airbus service information identified 
in table 2 to paragraph (g) of this AD specifies to contact Airbus 
for specific assessment, revise the maintenance or inspection 
program and accomplish all updated inspections, as applicable, using 
a method approved by the Manager, International Branch, ANM-116, 
Transport Airplane Directorate, FAA; or the European Aviation Safety 
Agency (EASA); or Airbus's EASA Design Organization Approval (DOA).
    (ii) Where the Airbus applicable service information identified 
in table 2 to paragraph (g) of this AD specifies ``current SRM,'' no 
SRM revision dated before April 2013 or SRM TR dated before November 
28, 2014, is considered a ``current SRM.''
    (2) For any repair that was previously allowed in any revision 
of the Airbus A330 or A340 SRM, as applicable, dated before April 
2013; or in any SRM TR dated before November 28, 2014, to the 
applicable SRM: Make an assessment using a method approved by the 
Manager, International Branch, ANM-116, Transport Airplane 
Directorate, FAA; or the EASA; or Airbus's EASA DOA and perform 
necessary corrective actions at the applicable times identified 
therein.

(i) Limitation on Repair/Replacement

    As of the effective date of this AD, for any structural damage 
in the areas identified in table 2 to paragraph (g) of this AD that 
has exceeded the ADL, no repair or replacement may be done using an 
Airbus A330 or A340 SRM dated before April 2013, or any SRM TR dated 
before November 28, 2014.

(j) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, FAA, has the authority to approve 
AMOCs for this AD, if requested using the procedures found in 14 CFR 
39.19. In accordance with 14 CFR 39.19, send your request to your 
principal inspector or local Flight Standards District Office, as 
appropriate. If sending information directly to the International 
Branch, send it to ATTN: Vladimir Ulyanov, Aerospace Engineer, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
1601 Lind Avenue SW., Renton, WA 98057-3356; telephone: 425-227-
1138; fax: 425-227-1149. Information may be emailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. 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. The AMOC approval letter must 
specifically reference this AD.
    (2) Contacting the Manufacturer: 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 
Branch, ANM-116, Transport Airplane Directorate, FAA; or EASA; or 
Airbus's EASA Design Organization Approval (DOA). If approved by the 
DOA, the approval must include the DOA-authorized signature.
    (3) Required for Compliance (RC): Except as required by 
paragraphs (h)(1)(i), (h)(1)(ii), and (h)(2) 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.
