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 A310 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) series airplanes. 
This proposed AD was prompted by a report of skin disbonding and damage 
found on the composite side panel of the rudder, located between the 
rudder core and skin of a previously repaired area. This proposed AD 
would require an inspection for disbonding or damage of certain 
rudders, and related investigative actions and corrective actions if 
necessary. We are proposing this AD to detect and correct disbonding 
and damage of the rudder, which could result in reduced structural 
integrity of the rudder and consequent reduced controllability of the 
airplane.

DATES: We must receive comments on this proposed AD by March 9, 2015.

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 
Airworthiness Directive 2014-0026, dated January 28, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    A case of skin disbonding was reported on a composite side of a 
rudder installed on an A310 aeroplane.
    The investigation results revealed that this disbonding started 
from a skin panel area previously repaired in-service in accordance 
with the Structural Repair Manual (SRM).
    The initial damage has been identified as a disbonding between 
the core and the repaired area. This damage may not be visually 
detectable and likely propagates during normal operation due to the 
variation of pressure during ground-air-ground cycles.
    This condition, if not detected and corrected, could affect the 
structural integrity of the rudder, possibly resulting in reduced 
control of the aeroplane.
    For the reasons described above, this [EASA] AD requires a one-
time thermography inspection of each repaired rudder or rudder whose 
maintenance records are incomplete and, depending on findings, 
accomplishment of applicable corrective and follow-up actions.

    Related investigative actions include doing a pulse thermography 
inspection for disbonding or damage of the left- and right-hand rudder 
side shells; a core ventilation through the inner skin, an elasticity 
laminate checker or ultrasonic inspection around the identified repairs 
in the booster area, and around identified fluid ingress; and a Tap 
test inspection of the glass fiber reinforced plastic area to identify 
skin-to-core disbonding and on identified repairs.

[[Page 3526]]

Corrective actions include repairing or replacing any disbonded or 
damaged rudder.
    Depending on configuration and inspection results, the repetitive 
inspection intervals are 750 or 1,000 flight cycles; or 500 flight 
hours or 4 months, whichever occurs later.
    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-2014-
1045.

Related Service Information

    Airbus has issued Service Bulletins A300-55-6050; and A310-55-2051; 
both Revision 01, dated August 20, 2014. The service information 
describes procedures for inspecting the left- and right-hand rudder 
side shells for disbonding or damage, and related investigative actions 
and corrective actions if necessary. The actions described in this 
service information are intended to correct the unsafe condition 
identified in the MCAI.

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.

Difference Between This Proposed AD and the MCAI or Service Information

    Airbus Service Bulletins A300-55-6050; and A310-55-2051; both 
Revision 01, dated August 20, 2014; do not provide corrective action 
for certain conditions. This proposed AD would require repairing the 
damage using a method approved by the Manager, International Branch, 
ANM-116, Transport Airplane Directorate, FAA; or the European Aviation 
Safety Agency (EASA); or Airbus's EASA Design Organization Approval 
(DOA).

Costs of Compliance

    We estimate that this proposed AD affects 199 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 proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost about $0 per 
product. Based on these figures, we estimate the cost of this proposed 
AD on U.S. operators to be $67,660, or $340 per product.
    We have received no definitive data that would enable us to provide 
a cost estimate for the on-condition actions specified in this proposed 
AD.

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.

side shell panel of that rudder since installation in accordance 
with the applicable structural repair manual (SRM).
    (4) The compliance time for the initial detailed inspection of 
the restored area for loose or lost tape identified in Tables 3 and
