RIN 2120-AA64


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 all 
Airbus Model A300 series airplanes; and Airbus 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 
proposed AD was prompted by a report of cracking of the lower tension 
bolt area at the rib one junction (both sides) of the lower wing. This 
proposed AD would require repetitive inspections for cracking of the 
fasteners and of the fitting around the fastener holes at the Frame 
(FR) 40 lower wing location, and corrective actions if necessary. We 
are proposing this AD to detect and correct crack initiation of the 
fittings of the FR40 lower wing locations, which could result in 
reduced structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by February 16, 
2016.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0272, dated December 12, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model A300 
series airplanes; and Airbus 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:

    Following the A300-600 Extended Service Goal (ESG2) exercise, 
specific inspections for cracks were performed in fittings of frame 
(FR) 40, in areas not covered by any existing task.
    Findings were identified on an A300-600 aeroplane withdrawn from 
service in the lower tension bolt area at rib one junction (both 
sides).
    This condition, if not detected and corrected, could lead to 
crack initiation, affecting the structural integrity of the 
aeroplane.
    To address this potential unsafe condition, an inspection 
programme was developed for the fitting around the fastener holes 
located at FR40 lower wing junction, left-hand (LH) and right-hand 
(RH) sides.
    For the reasons described above, this [EASA] AD requires 
repetitive High Frequency Eddy Current (HFEC) inspections and 
rototest inspections of the fitting around the fastener holes 
located at FR40 lower wing junction and, depending on findings, 
accomplishment of a repair.

    The corrective actions include a repair 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).
    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-2015-
8134.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Service Bulletins A300-57-0257 and A300-57-6115, 
both dated April 4, 2014. The service information describes procedures 
for repetitive inspections for cracking of the fasteners and of the 
fitting around the fastener holes at the FR40 lower wing location. 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 of this NPRM.

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

[[Page 81787]]

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.

Explanation of ``RC'' Procedures and Tests in Service Information

    The FAA worked in conjunction with industry, under the 
Airworthiness Directive Implementation Aviation Rulemaking Committee 
(ARC), to enhance the AD system. One enhancement was a new process for 
annotating which procedures and tests in the service information are 
required for compliance with an AD. Differentiating these procedures 
and tests from other tasks in the service information is expected to 
improve an owner's/operator's understanding of crucial AD requirements 
and help provide consistent judgment in AD compliance. The procedures 
and tests identified as Required for Compliance (RC) in any service 
information have a direct effect on detecting, preventing, resolving, 
or eliminating an identified unsafe condition.
    As specified in a NOTE under the Accomplishment Instructions of the 
specified service information, procedures and tests that are identified 
as RC in any service information must be done to comply with the 
proposed AD. However, procedures and 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 alternative method of compliance (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 will require approval of an AMOC.

Costs of Compliance

    We estimate that this proposed AD affects 166 airplanes of U.S. 
registry.
    We also estimate that it would take about 12 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 $169,320, or 
$1,020 per product.
    We have received no definitive data that would enable us to provide 
a cost estimate 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 
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.

    Within 1,000 flight hours after the effective date of this AD: 
Do a high frequency eddy current (HFEC) inspection for cracking of 
fasteners 1 through 3 at the left-hand and right-hand sides of the 
FR40 lower junction, and of the fitting around the fastener holes, 
in accordance with the Accomplishment Instructions of Airbus Service 
Bulletins A300-57-0257 (for Model A300 B2-1A, B2-1C, B2K-3C, B2-203, 
B4-2C, B4-103, and B4-203 airplanes) or A300-57-6115 (for Model A300 
B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, F4-605R, F4-622R, 
and C4-605R Variant F airplanes), both dated April 4, 2014, as 
applicable. If no cracking is found, repeat the HFEC inspection at 
intervals not to exceed 1,000 flight hours until a rototest 
inspection required by paragraph (h)(2) of this AD has been done.

[[Page 81788]]

(h) Repetitive Rototest Inspections

    Within 36 months after the effective date of this AD: Remove the 
fasteners and measure the diameter of the fastener holes; and, 
before further flight, do the applicable actions required by 
paragraph (h)(1) or (h)(2) of this AD, in accordance with the 
Accomplishment Instructions of Airbus Service Bulletin A300-57-0257 
(for Model A300 B2-1A, B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4-
203 airplanes) or A300-57-6115 (for Model A300 B4-601, B4-603, B4-
620, B4-622, B4-605R, B4-622R, F4-605R, F4-622R, and C4-605R Variant 
F airplanes), as applicable.
    (1) If one or more of the hole diameters is outside the 
tolerance of the nominal diameter, and outside the tolerance of the 
first and second oversize: Do the applicable corrective actions 
required by paragraph (i) of this AD.
    (2) If all of the hole diameters are within the tolerance of the 
nominal diameter or the first or second oversize: Do detailed and 
rototest inspections for cracking of the fastener holes at the left-
hand and right-hand sides of the FR40 lower junction, in accordance 
with the Accomplishment Instructions of Airbus Service Bulletins 
A300-57-0257 (for Model A300 B2-1A, B2-1C, B2K-3C, B2-203, B4-2C, 
B4-103, and B4-203 airplanes) or A300-57-6115 (for Model A300 B4-
601, B4-603, B4-620, B4-622, B4-605R, B4-622R, F4-605R, F4-622R, and 
C4-605R Variant F airplanes), both dated April 4, 2014, as 
applicable. If no cracking is found, before further flight, install 
new fasteners of the same diameter in special clearance fit for 
fasteners 1 through 3 of the FR40 lower junction, in accordance with 
the Accomplishment Instructions of Airbus Service Bulletins A300-57-
0257 or A300-57-6115, both dated April 4, 2014, as applicable. 
Repeat the rototest inspection thereafter at intervals not to exceed 
7,000 flight cycles. Accomplishment of a rototest inspection 
required by this paragraph terminates the repetitive HFEC 
inspections required by paragraph (g) of this AD.

(i) Corrective Actions

    If, during any inspection required by this AD, any crack is 
found, or one or more of the hole diameters are outside the 
tolerance of the nominal diameter: Repair before further flight 
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).

(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, Transport Airplane Directorate, FAA,
