Airworthiness Directives; Airbus Model A300-600 and A310 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed AD results from mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as: Surface defects were visually detected on the rudder of 
one Airbus A319 and one A321 in-service aeroplane. Investigation has 
determined that the defects reported on both rudders corresponded to 
areas that had been reworked in production. The investigation confirmed 
that the defects were the result of de-bonding between the skin and 
honeycomb core. Such reworks were also performed on some rudders fitted 
on A310 and A300-600 aeroplanes. An extended de-bonding, if not 
detected and corrected, may degrade the structural integrity of the 
rudder. The loss of the rudder leads to degradation of the handling 
qualities and reduces the controllability of the aeroplane.
    The proposed AD would require actions that are intended to address 
the unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by May 17, 2010.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2010-0002, dated January 5, 2010 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    Surface defects were visually detected on the rudder of one 
Airbus A319 and one A321 in-service aeroplane. Investigation has 
determined that the defects reported on both rudders corresponded to 
areas that had been reworked in production. The investigation 
confirmed that the defects were the result of de-bonding between the 
skin and honeycomb core. Such reworks were also performed on some 
rudders fitted on A310 and A300-600 aeroplanes.
    An extended de-bonding, if not detected and corrected, may 
degrade the structural integrity of the rudder. The loss of the 
rudder leads to degradation of the handling qualities and reduces 
the controllability of the aeroplane.
    To address this unsafe condition [this EASA AD] requires 
inspections of specific areas and, depending on findings, the 
application of corrective actions for those rudders where production 
reworks have been identified.
    This * * * [EASA] AD * * * also requires for the vacuum loss 
hole restoration:

--A local ultrasonic inspection for reinforced area instead of the 
local thermographic inspection, which is maintained for non-
reinforced areas, and
--Additional work performance for rudders on which this 
thermographic inspection has been performed in the reinforced area.

The inspections include vacuum loss inspections and elasticity laminate 
checker inspections for defects including de-bonding between the skin 
and honeycomb core of the rudder, and ultrasonic inspections for 
rudders on which temporary restoration with resin or permanent vacuum 
loss hole restoration has been performed. The corrective action is 
contacting the manufacturer for repair instructions and doing the 
repair. We are considering similar rulemaking action on Models A319 and 
A321 airplanes. You may obtain further information by examining the 
MCAI in the AD docket.

Relevant Service Information

    Airbus has issued All Operators Telex (AOT) A300-55A6047, Revision 
02, dated October 12, 2009; and AOT A310-55A2048, Revision 02, dated 
October 12, 2009. 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.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a Note within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 194 products 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. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $65,960, or $340 per product.

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); and
    3. 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

Subject

    (d) Air Transport Association (ATA) of America Code 55: 
Stabilizers.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    Surface defects were visually detected on the rudder of one 
Airbus A319 and one A321 in-service aeroplane. Investigation has 
determined that the defects reported on both rudders corresponded to 
areas that had been reworked in production. The investigation 
confirmed that the defects were the result of de-bonding between the 
skin and honeycomb core. Such reworks were also performed on some 
rudders fitted on A310 and A300-600 aeroplanes.
    An extended de-bonding, if not detected and corrected, may 
degrade the structural integrity of the rudder. The loss of the 
rudder leads to degradation of the handling qualities and reduces 
the controllability of the aeroplane.
    To address this unsafe condition [this EASA AD] requires 
inspections of specific areas and, depending on findings, the 
application of corrective actions for those rudders where production 
reworks have been identified.
    This * * * [EASA] AD * * * also requires for the vacuum loss 
hole restoration:

--A local ultrasonic inspection for reinforced area instead of the 
local thermographic inspection, which is maintained for non-
reinforced areas, and
--Additional work performance for rudders on which this 
thermographic inspection has been performed in the reinforced area.

[[Page 16688]]

The inspections include vacuum loss inspections and elasticity 
laminate checker inspections for defects including de-bonding 
between the skin and honeycomb core of the rudder, and ultrasonic 
inspections for rudders on which temporary restoration with resin or 
permanent vacuum loss hole restoration has been performed. The 
corrective action is contacting the manufacturer for repair 
instructions and doing the repair. We are considering similar 
rulemaking action on Models A319 and A321 airplanes.
