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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>
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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>, 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.
