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 all Airbus Model A330-200, 
A330-200 Freighter, A330-300, A340-500, and A340-600 series airplanes; 
and A340-313 airplanes. The NPRM published in the Federal Register on 
December 28, 2016 (81 FR 95538) (``the NPRM''). The NPRM was prompted 
by the discovery of TSA/CAA surface treatment in certain bulk cargo 
door frame holes of certain airplanes. The NPRM proposed to require 
inspection of the fuselage bulk cargo door frames at specific 
locations, and corrective action if necessary. We are issuing this AD 
to detect and correct fatigue cracks in the bulk cargo door frames, 
caused by TSA/CAA surface treatment in certain bulk cargo door frame 
holes. Cracks in the bulk cargo door frames can cause the in-flight 
loss of a bulk cargo door, damage to the airplane, and subsequent 
reduced control 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 
Airworthiness Directive 2016-0102, dated June 1, 2016; corrected June 
7, 2016 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''); to correct an unsafe 
condition for all Airbus Model A330-200, A330-200 Freighter, A330-300, 
A340-500, and A340-600 series airplanes; and A340-313 airplanes. The 
MCAI states:

    In the frame of the certification of the A330 Extended Service 
Goal exercise, it has been identified that Tartaric Sulfuric 
Anodising (TSA)/Chromic Acid Anodising (CAA) surface treatment is 
present in some frame holes, from aeroplane MSN [manufacturer serial 
number] 0400 and later MSN, following production process 
modification. On bulk cargo door frames (FR) 67 and FR 69 Right Hand 
Side, the door fitting attachment holes have this TSA/CAA

[[Page 41875]]

treatment, which leads to a detrimental effect on fatigue behaviour. 
This condition, if not detected and corrected, could lead to 
critical cracks in the primary structure, possibly resulting in in-
flight loss of a bulk cargo door, consequent decompression and 
potential damage to the aeroplane that could reduce the control of 
the aeroplane.
    To address this potential unsafe condition, Airbus issued Alert 
Operators Transmission (AOT) A53L012-16 to provide instructions to 
inspect the fuselage bulk cargo door frames at specific locations.
    For the reasons described above, this [EASA] AD requires 
repetitive non-destructive test (rototest and high-frequency eddy-
current (HFEC)) inspection or visual detailed (DET) inspections [to 
detect cracking] of the affected areas, and, depending on findings, 
accomplishment of a repair.
    This [EASA] AD is considered an interim measure, and further 
[EASA] AD action may follow.

    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-
9517.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM and 
the FAA's response to that comment.

Request To Remove the Reporting Requirement

    Lufthansa agrees that reporting inspection results, as proposed in 
paragraph (k) of the proposed AD, is beneficial to the original 
equipment manufacturer (OEM). However, Lufthansa disagrees that 
reporting should be a hard requirement for operators. Lufthansa does 
not consider that reporting or non-reporting is an airworthiness 
concern for the affected aircraft. Lufthansa does not agree with the 
potential of having to ground an aircraft just because the reporting 
may be provided later than 30 days after inspection. According to 
Lufthansa, some layover may, in fact, take more than 30 days to 
complete; in such cases, the aircraft may not yet be released back into 
service, and the reporting as proposed could become overdue. Lufthansa 
considers that because of these circumstances, reporting should be a 
strong recommendation, but not a requirement.
    We find that reporting of inspection results for the affected 
aircraft is necessary. Reporting allows the manufacturer to collect 
airworthiness information from operators in order to fully understand 
the scope of the unsafe condition and to develop a final solution as a 
terminating action. Reporting is not intended to ground aircraft and is 
only required after the inspections required by paragraphs (g) and (h) 
of this AD have been completed. We have made no change to this AD in 
this regard.

Conclusion

    We reviewed the relevant data, considered the comment received, 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.

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.

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.
