14 CFR Part 39

[Docket No. FAA-2014-0340; Directorate Identifier 2014-NM-084-AD; 
Amendment 39-17867; AD 2014-12-06]
RIN 2120-AA64


Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
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); and Airbus Model A310 series airplanes. This AD 
requires inspections of the external area of the aft cargo door sill 
beam for cracking, and repair if necessary. This AD was prompted by 
reports of fatigue cracks on the cargo door sill beam, lock fitting, 
and torsion box plate. We are issuing this AD to detect and correct 
fatigue cracking of the cargo door sill beam, lock fitting, and torsion 
box plate, which could result in the loss of the door locking function 
and, subsequently, complete loss of the cargo door in flight with the 
risk of rapid decompression.

DATES: This AD becomes effective July 2, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of July 2, 
2014.

SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Emergency Airworthiness Directive 2014-0097-E, dated April 23, 2014 
(referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain Airbus Model A300 B4-600, B4-600R, and F4-600R series 
airplanes, and Model A300 C4-605R Variant F airplanes (collectively 
called Model A300-600 series airplanes); and Airbus Model A310 series 
airplanes. The MCAI states:

    During accomplishment of Maintenance Review Board Report (MRBR) 
task 531625-01-1 on an A300-600 aeroplane having accumulated more 
than 25,000 flight cycles (FC) since aeroplane first flight, 
multiple fatigue cracks were found on the following parts:

--Aft cargo door sill beam Part Number (P/N) A53973085210
--Lock fitting P/N A53978239002
--Torsion box plate P/N A53973318206.

    Prompted by these findings, a stress analysis was performed 
during which it was discovered that there is no dedicated scheduled 
maintenance task to inspect the affected area for fatigue damage.
    The loss of more than one lock fitting could lead to loss of the 
door locking function and, subsequently, complete loss of the cargo 
door in flight with associated risk of rapid decompression.
    To address this unsafe condition, Airbus issued Alert Operators 
Transmission (AOT) A53W005-14 providing instructions for inspection 
of the affected area.
    For the reason described above, this [EASA] AD requires 
repetitive ultrasonic inspections or detailed inspections (DET) for 
cracking of the aft cargo door sill beam external area, or a one-
time High Frequency Eddy Current (HFEC) inspection [for cracking] of 
the aft cargo door sill beam internal structure and, depending on 
findings, accomplishment of corrective action(s) [e.g. repair].
    This [EASA] AD is considered an interim measure and further AD 
action may follow.

You may examine the MCAI on the Internet at http://www.regulations.gov 
by searching for and locating Docket No. FAA-2014-0340.

Relevant Service Information

    Airbus has issued Alert Operators Transmission A53W005-14, dated 
April 22, 2014. The actions described in this service information are 
intended to correct the unsafe condition identified in the MCAI.

[[Page 34404]]

FAA's Determination and Requirements of This 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 issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

Interim Action

    We consider this AD interim action. If final action is later 
identified, we might consider further rulemaking then.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
fatigue cracking of the cargo door sill beam, lock fitting, and torsion 
box plate could result in the loss of the door locking function and 
subsequently, complete loss of the cargo door in flight with the risk 
of rapid decompression. Therefore, we determined that notice and 
opportunity for public comment before issuing this AD are impracticable 
and that good cause exists for making this amendment effective in fewer 
than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2014-0340; Directorate 
Identifier 2014-NM-084-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD based on 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 170 airplanes of U.S. registry.
    We also estimate that it will take about 11 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $158,950, or $935 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.

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 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.
