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 series airplanes; 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 
Model A310 series airplanes. This proposed AD was prompted by a report 
indicating that during inspections to detect corrosion of the bulk 
cargo doors, several cracks were discovered. This proposed AD would 
require a general visual inspection of the bulk cargo door frame to 
identify any structural repairs, a detailed visual inspection of the 
frame at the repaired area for any cracking if necessary, and 
corrective actions if necessary. We are proposing this AD to detect and 
correct cracking of the bulk cargo doors; such cracking could result in 
rapid airplane decompression or possible loss of the bulk cargo door.

DATES: We must receive comments on this proposed AD by August 12, 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 2015-0238, dated December 18, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for Airbus Model A300 
series airplanes; 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 Model A310 series 
airplanes. The MCAI states:

    During inspections to detect corrosion on the Bulk Cargo Doors 
of Airbus A300 family aeroplanes, several cracks were discovered. 
Investigations revealed that a set of SRM [structural repair manual] 
repair solutions was defined in 1993, and was classified as 
permanent and without limitation. As of 2011, this set of repair 
solutions was revised and classified permanent, but with post-repair 
required actions.
    This condition, if not detected and corrected, could result in 
rapid decompression events or even loss of the bulk cargo door.
    As per Ageing Aircraft rules, it was determined that new 
inspections have to be completed on the Bulk Cargo Door Frames to 
detect potential fatigue damages on repaired structures or to 
perform a new repair scheme.
    Based on the fact that several aeroplanes could potentially be 
flying with potential fatigue damages on repaired structures, Airbus 
was requested to issue Alert Operator Transmission (AOT) A53W010-15 
to provide fleet-wide inspection instructions to address this 
condition.
    For the reasons describes above, this [EASA] AD requires a one-
time inspection of the bulk cargo door frame to determine whether a 
repair has been accomplished and, depending on findings, 
accomplishment of applicable corrective action(s).

    The required actions in this NPRM include a detailed visual 
inspection of the bulk cargo door frame at the repaired area for any 
cracking, repair of cracks, and post-repair inspections of crack-free 
frames. 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-2016-7269.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Alert Operators Transmission A53W010-15, 
Revision 00, including Appendixes 1, 2, and 3, dated December 15, 2015. 
The service information describes a general visual inspection of the 
bulk cargo door frame to identify any structural repairs, and a 
detailed visual inspection of the frame at the repaired area. 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.

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 135 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
             Action                        Labor cost             Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
Inspection......................  1 work-hour x $85 per hour               $0              $85          $11,475
                                   = $85.
----------------------------------------------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD, except for the cost of reporting, specified as follows:

                           On-Condition Costs
------------------------------------------------------------------------
                                                             Cost per
        Action            Labor cost       Parts cost        product

                        $85 per hour =
                        $85.

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 proposed AD 
is 2120-0056. The paperwork cost associated with this proposed 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 proposed 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 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.
