14 CFR Part 39

[Docket No. FAA-2014-0448; Directorate Identifier 2013-NM-055-AD; 
Amendment 39-18048; AD 2014-25-06]
RIN 2120-AA64


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 all 
Airbus Model A300 series airplanes; 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. This AD was prompted by a report of 
early ruptures on the levers of the nose landing gear (NLG) sequence 
valve. This AD requires a one-time inspection for damage of the landing 
gear sequence valve levers and pin shearing indicating areas on the NLG 
and the main landing gears (MLGs); and depending on findings, replacing 
the sequence valve and lever, or doing a one-time inspection to detect 
interference between control rods and sequence valves and corrective 
actions if necessary. We are issuing this AD to detect and correct 
interference between a landing gear leg and door, which could result in 
failure of that landing gear to extend and could damage the airplane 
and injure occupants.

DATES: This AD becomes effective January 20, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of January 20, 
2015.

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 A300 
series airplanes; 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. The NPRM published in the Federal Register on July 16, 2014 
(79 FR 41459).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2013-0058, dated March 11, 2013 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model A300 
series airplanes; 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. The MCAI states:

    Operators have reported five cases of early ruptures on levers 
of the nose landing gear (NLG) sequence valve.
    Analysis showed that these fatigue ruptures were due to an 
incorrect adjustment of the mechanical links. As the design of the 
main landing gear (MLG) sequence valve lever is similar, there is 
sufficient reason to assume that these parts are similarly affected 
by fatigue.
    This condition, if not detected and corrected, could lead to 
interference between landing gear leg and door and consequent 
failure of the landing gear to extend, possibly resulting in damage 
to the aeroplane and injury to occupants.
    For the reasons described above, this [EASA] AD requires a one-
time inspection of the sequence valve control lever [for damage, 
which could include cracking or deformation], of the adjustment of 
the control rod between doors and landing gear sequence valve and 
depending on inspections results, accomplishment of applicable 
corrective actions.


[[Page 74606]]


    The corrective actions include adjusting the control rod between 
the door and the sequence valves; adjusting mechanical linkages; and 
replacing/installing a serviceable valve and lever. You may examine the 
MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0448-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 41459, July 16, 
2014) 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 (79 FR 41459, July 16, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 41459, July 16, 2014).

Costs of Compliance

    We estimate that this AD affects 128 airplanes of U.S. registry.
    We also estimate that it would take about 4 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $43,520, or $340 per product.
    In addition, we estimate that any necessary follow-on actions would 
take up to 9 work-hours and require parts costing up to $42,000, for a 
cost of $42,765 per product. We have no way of determining the number 
of aircraft that might need these actions.

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 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.
