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 A300 B4-2C, B4-103, and B4-203 airplanes; Airbus 
Model A300 B4-600 series airplanes; and Airbus Model A300 B4-600R 
series airplanes. This proposed AD was prompted by reports indicating 
that, on airplanes that received a certain repair following crack 
findings, cracks can re-initiate. This proposed AD would require 
repetitive inspections for cracking of the frame (FR) 40 forward 
fittings for airplanes previously repaired. We are proposing this AD to 
detect and correct cracking on the FR 40 forward fittings, which could 
result in rupture of the forward fittings and reduction of in-flight 
structural strength.

DATES: We must receive comments on this proposed AD by March 30, 2015.

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 
Airworthiness Directive 2014-0199, dated September 05, 2014 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A300 B4-2C, B4-103, and B4-203 airplanes; Airbus Model A300 B4-600 
series airplanes; and Airbus Model A300 B4-600R series airplanes. The 
MCAI states:

    During routine inspection on an A300-600 aeroplane, a crack was 
found in the right-hand frame (FR) 40 forward fitting between 
stringer (STRG) 32 and STRG 33. The subject aeroplane had previously 
been modified, as a crack prevention measure, in accordance with 
Airbus SB A300-57-6053 (mod 10453).
    To ensure the structural integrity of FR 40, pending completion 
of the full root cause analysis using a refined Finite Element Model 
(FEM), EASA issued AD 2009-0094 [dated April 21, 2009, http://ad.easa.europa.eu/ad/2009-0094], to require, a one-time Detailed 
Visual Inspection (DVI) of A300 and A300-600 aeroplanes on which 
Airbus SB A300-53-0297 or SB A300-57-6053, as applicable, was 
embodied as a crack prevention measure.
    Thereafter, cracks were found during maintenance check in the FR 
40 forward fitting on two aeroplanes, one A300 with Airbus SB A300-
53-0297 embodied and one A300-600 with Airbus SB A300-57-6053 
embodied. EASA AD 2009-0094 had been accomplished on both 
aeroplanes.
    Consequently, EASA issued AD 2011-0163 [dated August 30, 2011, 
http://ad.easa.europa.eu/ad/2011-0163], superseding EASA AD 2009-
0094, to require, for aeroplanes modified preventively, repetitive 
DVI of the FR 40 forward fitting (without nut removal), 
accomplishment of a one-time Eddy Current (EC) inspection or liquid 
penetrant inspection of this area (with nut removal) and, depending 
on findings, the accomplishment of associated corrective actions.
    A detailed FEM study was recently completed which demonstrated 
that, on aeroplanes repaired following crack findings in accordance 
with the instructions of Airbus SB A300-53-0297 or SB A300-57-6053 
at any revision, as applicable, cracks can re-initiate.
    For the reasons described above, this [EASA] AD requires 
repetitive inspections of the FR 40 forward fitting for aeroplanes 
repaired in accordance with the instructions of Airbus SB A300-53-
0297 or SB A300-57-6053 following crack findings.

    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-
0084.

Relevant Service Information Under 1 CFR Part 51

    We reviewed the following Airbus service information:
    <bullet> Airbus A300 Alert Operators Transmission (AOT) A53W002-14, 
dated April 02, 2014.
    <bullet> Airbus A300 AOT A57W003-14, Revision 01, dated April 17, 
2014.
    Airbus A300 Alert Operators Transmission (AOT) A53W002-14, dated 
April 02, 2014, describes procedures for repetitive inspections of the 
FR40 forward fitting on A300 aircraft post MOD 10453S20571. Airbus A300 
AOT A57W003-14, Revision 01, dated April 17, 2014, describes procedures 
for repetitive inspections of the FR40 forward fitting on A300-600 
aircraft pre MOD 10221S20394 and post MOD 10453S20571. The actions 
described in this service information are intended to correct the 
unsafe condition identified in the MCAI. This service information is 
reasonably available; see ADDRESSES for ways to access this service 
information.

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.

Costs of Compliance

    We estimate that this proposed AD affects 26 airplanes of U.S. 
registry.
    We also estimate that it would take about 3 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 $6,630, or $255 
per product.

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.
