[Docket No. FAA-2016-8184; Directorate Identifier 2016-NM-036-AD]
RIN 2120-AA64


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 all 
Airbus Model A300 series airplanes; and 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). This 
proposed AD was prompted by reports of cracks in certain pins in the 
main landing gear (MLG). This proposed AD would require repetitive 
detailed visual inspections of the pins for cracks, and replacing the 
MLG leg if necessary. We are proposing this AD to detect and correct 
cracking of certain pins in the MLG, which could result in a MLG 
collapse, and consequent damage to the airplane and injury to the 
airplane occupants.

DATES: We must receive comments on this proposed AD by September 19, 
2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2016-0058, dated March 21, 2016, (referred to after this as ``the 
MCAI''), to correct an unsafe condition for all Airbus Model A300 
series airplanes; and 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). The MCAI states:

    Two cases were reported of finding a cracked main landing gear 
(MLG) hinge arm/barrel pin, one was discovered in service during a 
maintenance task and the other one was identified during MLG 
overhaul.
    This condition, if not detected and corrected, could lead to MLG 
collapse, resulting in damage to the aeroplane and potential injury 
to occupants.
    To address this potential unsafe condition, and awaiting a final 
fix establishment, Airbus issued Alert Operators Transmission (AOT) 
32W008-16 to provide instructions for detailed visual inspections 
(DET) to detect through cracks.
    For the reasons described above, this [EASA] AD requires 
repetitive DET of the MLG hinge arm/barrel pin and, depending on 
findings, replacement of the affected MLG leg.

    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-
8184.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Alert Operators Transmission (AOT) 32W008-16, 
dated February 25, 2016. This service information describes detailed 
visual inspection and replacement procedures for the MLG hinge arm and 
barrel pin. 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 128 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs

    We estimate the following costs to do any necessary replacement 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of airplanes that might need 
this replacement.

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

intervals not to exceed 100 flight cycles, accomplish a detailed 
visual inspection of the internal diameter of each affected MLG 
hinge arm/barrel pin, in accordance with the instructions of Airbus 
Alert Operators Transmission (AOT) A32W008-16, dated February 25, 
2016. The affected MLG hinge arm/barrel pins are those with part 
number C66441-(x) and part number C65543-(x), where the x represents 
a variable number.
    (1) Within 30 months since the pin's first flight on an 
airplane, or since the pin's first flight on an airplane after 
overhaul, as applicable.
    (2) Within 30 days after the effective date of this AD.

(h) Corrective Action for Detailed Visual Inspection

    If any crack is found during any inspection required by 
paragraph (g) of this AD, before further flight, replace the MLG leg 
with a serviceable unit, in accordance with the instructions of 
Airbus AOT A32W008-16, dated February 25, 2016. Replacement of a MLG 
leg does not constitute terminating action for the repetitive 
inspections required by paragraph (g) of this AD.

(i) Reporting Requirement

    At the applicable time specified in paragraph (i)(1) or (i)(2) 
of this AD, report the results of the inspections required by 
paragraph (g) of this AD to Airbus in accordance with the 
instructions of Airbus AOT A32W008-16, dated February 25, 2016.
    (1) If the inspection was done on or after the effective date of 
this AD: Submit the report within 30 days after the inspection.
    (2) If the inspection was done before the effective date of this 
AD: Submit the report within 30 days after the effective date of 
this AD.
