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 
certain Airbus Model A300 B4-601, B4-603, and B4-605R airplanes, Model 
A300 F4-605R airplanes, Model A300 C4-605R Variant F airplanes, and 
Model A310-204 and -304 airplanes, powered by General Electric (GE) 
CF6-80C2 series engines. This proposed AD was prompted by reports of 
two single-engine flame-out events during inclement weather. This 
proposed AD would require installing a shunt of the rotary selector 
(introducing an auto-relight function). We are proposing this AD to 
prevent a long engine restart sequence after a non-selection of 
continuous re-light by the crew and a flame-out event of both engines, 
which could result in reduced controllability of the airplane, 
especially at low altitude.

DATES: We must receive comments on this proposed AD by August 2, 2012.

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 2011-0113, dated June 17, 2011 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    Two single [engine] flame out events attributed to inclement 
weather occurred on Wide Body (WB) aeroplanes powered with GE CF6-
80C2 engines.
    On WB aeroplanes, no auto-relight function is embodied. To avoid 
long engine restart sequence after a non selection of continuous 
relight by the crew and a flame out event of both engines, resulting 
in strongly reduced control of the aeroplane especially at low 
altitude, the manufacturer Airbus designed a modification by 
introducing auto-relight function for aeroplanes powered by GE CF6-
80C2 engines.
    For the reason described above, this EASA AD requires the 
installation on the aeroplane of an auto-relight function 
[installing a shunt of the rotary selector] as a precaution and to 
increase restart capability without crew action.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletin A310-74-2003, Revision 
02, including Appendix 1, dated February 9, 2012 (for Model A310-204 
and -304 airplanes); and Mandatory Service Bulletin A300-74-6003, 
Revision 02, including Appendix 1, dated February 9, 2012 (for Model 
A300 B4-601, B4-603, and B4-605R airplanes, Model A300 F4-605R 
airplanes, and Model A300 C4-605R Variant F airplanes). 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.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 47 products of U.S. registry. We also estimate that 
it would take about 80 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 $12,500 per product. Where 
the service information lists required parts costs that are covered 
under warranty, we have assumed that there will be no charge for these 
parts. As we do not control warranty coverage for affected parties, 
some parties may incur costs higher than estimated here. Based on these 
figures, we estimate the cost of the proposed AD on U.S. operators to 
be $907,100, or $19,300 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);
    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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

The Proposed Amendment

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

AMOCs for this AD, if requested using the procedures found in 14 CFR 
39.19. In accordance with 14 CFR 39.19, send your request to your 
principal inspector or local Flight Standards District Office, as 
appropriate. If sending information directly to the International 
Branch send it to ATTN: Dan Rodina, Aerospace Engineer,

your appropriate principal inspector, or lacking a principal 
inspector, the manager of the local flight standards district 
office/certificate holding district office. The AMOC approval letter 
must specifically reference this AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
