Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Airbus Model A300 series airplanes; and 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). This AD was 
prompted by reports of cracks initiating at the upper radius of a 
certain frame and a determination that the current inspection procedure 
is not reliable in detecting certain cracking of the forward fitting of 
the frame. This AD requires repetitive inspections to detect cracking 
of the upper radius of the forward fitting of a certain frame, and 
related investigative actions and corrective actions if necessary. We 
are issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective September 25, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 25, 
2017.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Airbus Model A300 
series airplanes; and 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). The NPRM published in the 
Federal Register on May 31, 2017 (82 FR 24903) (``the NPRM''). The NPRM 
was prompted by reports of cracks initiating at the upper radius of 
frame (FR) 47 and a determination that the current inspection procedure 
is not reliable in detecting certain cracking of the forward fitting of 
FR 47. The NPRM proposed to require repetitive inspections to detect 
cracking of the upper radius of the forward fitting of FR 47, and 
related investigative actions and corrective actions if necessary. We 
are issuing this AD to detect and correct fatigue cracking of the FR 47 
forward fitting upper radius on the left-hand and right-hand sides of 
the fuselage, which could propagate and result in reduced structural 
integrity of the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2016-0150, dated July 25, 2016 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition on all. The MCAI states:

    During scheduled maintenance inspections on the fuselage, cracks 
initiating at the upper radius of frame (FR) 47 have been reported 
on several aeroplanes. Similar damage was also discovered on the 
A300 fatigue test fuselage.
    This condition, if not detected and corrected, could reduce the 
structural integrity of the fuselage.
    Prompted by these findings, Airbus issued Service Bulletin (SB) 
A300-53-0246, SB A300-53-6029 and SB A300-53-9014 to provide 
inspection instructions and, consequently, DGAC France issued AD F-
2006-016 to require repetitive inspections and corrective action.
    Since that [French] AD was issued, further investigation led to 
the conclusion that the current ultrasonic inspection performed in 
accordance with Airbus SB A300-53-0246 Revision 06, or SB A300-53-
6029 Revision 08, or SB A300-53-9014 Revision 01, as applicable, was 
not reliable to detect deep crack going downward.
    Consequently, to ensure the crack depth is correctly measured 
whatever the crack direction, Airbus developed a new nondestructive 
testing method [eddy current]

[[Page 39521]]

for this special detailed inspection (SDI) and revised the affected 
SBs accordingly.
    For the reasons described above, this [EASA] AD retains the 
requirements of DGAC France AD F-2006-016, which is superseded, but 
requires the accomplishment of repetitive SDI to replace the 
previously required ultrasonic inspections [and related 
investigative and corrective actions if necessary].

Related investigative actions include an ultrasonic inspection for 
cracking on the forward face of the forward fitting and a detailed 
inspection for cracking of the aft fitting around the fasteners. 
Corrective actions include crack repairs, and modification of the 
sealing fittings and sealing shims. This AD requires reporting of the 
inspection results to Airbus. 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-2017-0520.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Airbus Service Bulletin A300-53-0246, Revision 
08, including Appendix 1, dated April 13, 2016 (for Model A300 series 
airplanes); and Airbus Service Bulletin A300-53-6029, Revision 12, 
including Appendix 1, dated April 13, 2016 (for Model A300-600 series 
airplanes). The service information describes procedures for doing an 
SDI for cracking of the FR 47 forward fitting upper radius on the left-
hand and right-hand sides of the fuselage, and related investigative 
and corrective actions. 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.

Costs of Compliance

    We estimate that this AD will affect 132 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this AD:

    We estimate the following costs to do any necessary related 
investigative and corrective actions that would be required based on 
the results of the inspection. We have no way of determining the number 
of aircraft that might need these repairs:

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

[[Page 39522]]

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.
