Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) AD 2016-
20-11, 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. AD 2016-20-11 requires repetitive inspections of 
the external area of the aft cargo door sill beam for cracking, 
repetitive inspections for fatigue cracking of the cargo door sill 
beam, lock fitting, and torsion box plate, and repair if necessary. 
Since we issued AD 2016-20-11, we have determined that reinforcement of 
the aft cargo door sill beam area is necessary to address the unsafe 
condition, which constitutes terminating action for the repetitive 
inspections. This proposed AD would retain the inspections for 
cracking, and repair if necessary; and require reinforcement of the aft 
cargo door sill beam area. We are proposing this AD to address the 
unsafe condition on these products.

DATES: We must receive comments on this proposed AD by September 11, 
2017.

Discussion

    On September 28, 2016, we issued AD 2016-20-11, Amendment 39-18677 
(81 FR 85837, November 29, 2016) (``AD 2016-20-11''), for certain 
Airbus Model A300-600 series airplanes; and Airbus Model A310 series 
airplanes. AD 2016-20-11 was prompted by reports of fatigue cracks on 
the cargo door sill beam, lock fitting, and torsion box plate. AD 2016-
20-11 requires repetitive ultrasonic and detailed inspections of the 
external area of the aft cargo door sill beam for cracking, repetitive 
high frequency eddy current (HFEC) inspections for fatigue cracking of 
the cargo door sill beam, lock fitting, and torsion box plate, and 
repair if necessary. We issued AD 2016-20-11 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, loss of the cargo door in flight and rapid 
decompression.
    Since we issued AD 2016-20-11, Airbus has developed a reinforcement 
modification of the aft cargo door sill beam area, which constitutes 
terminating action for the repetitive inspections. We have determined 
the reinforcement of the aft cargo door sill beam area is necessary to 
address the unsafe condition.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0048, dated March 15, 2017; corrected April 20, 2017 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A300-600 series airplanes; and Airbus Model A310 series airplanes. The 
MCAI states:

    In the frame of the widespread fatigue damage (WFD) compliance 
study and after an in-service occurrence, the area of the aft cargo 
door sill beam and adjacent structure was identified as sensitive to 
the fatigue loads.
    This condition, if not detected and corrected, could lead to 
failure of multiple lock fittings, possibly resulting in loss of the 
cargo door in flight and consequent explosive decompression of the 
aeroplane.

[[Page 34892]]

    To address this potential unsafe condition, Airbus issued Alert 
Operators Transmission (AOT) A53W005-14 providing inspection 
instructions and, consequently, EASA issued Emergency AD 2014-0097-E 
[which corresponded to FAA AD 2014-12-06] to require repetitive 
ultrasonic inspections (US) or detailed inspections (DET) of the aft 
cargo door sill beam area [and corrective actions if necessary].
    After that [EASA] AD was issued, further analysis indicated that 
repetitive high frequency eddy current (HFEC) inspections needed to 
be introduced, and Airbus published Service Bulletin (SB) A310-53-
2139 and SB A300-53-6179 to provide instructions. Prompted by this 
determination, EASA issued AD 2015-0150, retaining the requirements 
of EASA Emergency AD 2014-0097-E, which was superseded, and required 
repetitive HFEC inspections of the concerned areas. The first HFEC 
inspection terminated the repetitive US/DET inspections. That [EASA] 
AD also required the inspection results to be reported.
    Since that [EASA] AD was issued, Airbus developed a 
reinforcement modification of the aft cargo door sill beam area, and 
published Airbus SB A310-53-2141 and SB A300-53-6181, which were 
revised lately, to make this available for in-service application.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2015-0150 [which corresponded to FAA AD 
2016-20-11], which is superseded, and requires modification 
[reinforcement] of the aft cargo door sill beam, which constitutes 
terminating action for the repetitive inspections.
    This [EASA] AD is re-published to correct the compliance time 
description in Table 4.

    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-2017-
0708.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Airbus Service Bulletin A300-53-6181, Revision 
01, dated July 2, 2015; and A310-53-2141, Revision 01, dated July 2, 
2015. This service information describes procedures for reinforcing the 
aft cargo door sill beam. These service bulletins are distinct since 
they apply to different airplane models.
    Airbus has issued Airbus Service Bulletin A300-53-6179, dated 
December 12, 2014; and A310-53-2139, dated December 12, 2014. This 
service information describes procedures for repetitive HFEC 
inspections of the cargo door sill beam, lock fitting, and torsion box 
plate. These service bulletins are distinct since they apply to 
different airplane models.
    Airbus has also issued AOT A53W005-14, Revision 01, dated April 29, 
2014, which describes procedures for doing an ultrasonic inspection or 
detailed inspection of the aft cargo door sill beam external area for 
cracking.
    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 the same 
type design.

Costs of Compliance

    We estimate that this AD affects 75 airplanes of U.S. registry. We 
estimate the following costs to comply with this proposed AD:

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a

[[Page 34893]]

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.
