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:

    Cracks have been found on pylon side panels (upper section) at 
rib 8 on Airbus A300, A310 and A300-600 aircraft equipped with 
General Electric engines. Investigation of these findings indicates 
that this problem is likely to affect aircraft of this type design 
with other engine installations. This condition, if not corrected, 
can lead to reduced strength [structural integrity] of the pylon 
primary structure.

The unsafe condition is reduced structural integrity of the pylon 
primary structure, which could cause detachment of the engine from the 
fuselage. 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 November 5, 
2009.

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 2008-0181, dated October 1, 2008 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    Cracks have been found on pylon side panels (upper section) at 
rib 8 on Airbus A300, A310 and A300-600 aircraft equipped with 
General Electric engines. Investigation of these findings indicates 
that this problem is likely to affect aircraft of this type design 
with other engine installations. This condition, if not corrected, 
can lead to reduced strength [structural integrity] of the pylon 
primary structure.
    In order to detect any crack propagation at an early stage, thus 
avoiding an extensive repair, Airbus issued Service Bulletins (SB) 
A300-54-0075, A310-54-2018 and A300-54-6015. * * *
    This AD requires the implementation of this * * * inspection 
programme.

The unsafe condition is reduced structural integrity of the pylon 
primary structure, which could cause detachment of the engine from the 
fuselage. Required actions include repetitive detailed visual 
inspections, or repetitive eddy current and detailed visual 
inspections, to detect cracks, depending on the airplane configuration, 
and corrective actions if necessary. The corrective actions include 
repairing the cracking, and

[[Page 48025]]

contacting Airbus for repair instructions and doing the repair, as 
applicable.
    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletins A300-54-0075, A310-
54-2018, and A300-54-6015, all Revision 02, all including Appendices 1, 
2, and 3, all dated June 26, 2008. The actions described in this 
service information are intended to correct the unsafe condition 
identified in the MCAI.
    Depending on the model and engine type, the initial compliance 
times for doing the inspections range between 9,300 flight cycles since 
doing the repair or modification and 22,600 flight cycles or 45,200 
flight hours, whichever occurs first, since doing the repair or 
modification; the repetitive intervals are between 5,300 flight cycles 
and 33,900 flight cycles or 67,800 flight hours, whichever occurs 
first.

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 230 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 $80 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $73,600, or $320 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 54: 
Nacelles/Pylons.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    Cracks have been found on pylon side panels (upper section) at 
rib 8 on Airbus A300, A310 and A300-600 aircraft equipped with 
General Electric engines. Investigation of these findings indicates 
that this problem is likely to affect aircraft of this type design 
with other engine installations. This condition, if not corrected, 
can lead to reduced strength [structural integrity] of the pylon 
primary structure.
    In order to detect any crack propagation at an early stage, thus 
avoiding an extensive repair, Airbus issued Service Bulletins (SB) 
A300-54-0075, A310-54-2018 and A300-54-6015. * * *
    This AD requires the implementation of this * * * inspection 
programme.

The unsafe condition is reduced structural integrity of the pylon 
primary structure, which could cause detachment of the engine from 
the fuselage. Required actions include repetitive detailed visual 
inspections, or repetitive eddy current and detailed visual 
inspections, to detect cracks, depending on the airplane 
configuration, and corrective

[[Page 48026]]

actions if necessary. The corrective actions include repairing the 
cracking, and contacting Airbus for repair instructions and doing 
the repair, as applicable.

Actions and Compliance

    (f) Unless already done, do the following actions.
    (1) For Configuration 01 airplanes as identified in the 
applicable service bulletin identified in Table 2 of this AD: At the 
applicable time specified in Table 1 of this AD, except as required 
by paragraphs (f)(2) and (f)(3) of this AD, perform a detailed 
visual inspection of the pylons 1 and 2 side panels (upper section) 
at rib 8, in accordance with the Accomplishment Instructions of the 
applicable service bulletin identified in Table 2 of this AD. Repeat 
the inspection at the time specified in Table 1 of this AD.

FAA AD Differences

    Note 1:  This AD differs from the MCAI and/or service 
information as follows: Although the MCAI/service information allows 
further flight after cracks are found during compliance with certain 
actions, this AD requires that you repair the crack(s) before 
further flight.

Other FAA AD Provisions

    (g) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
has the authority to approve AMOCs for this AD, if requested using 
the procedures found in 14 CFR 39.19. Send information to ATTN: Dan 
Rodina, Aerospace Engineer, International Branch, ANM-116, Transport 
Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 
98057-3356; telephone (425) 227-2125; fax (425) 227-1149. Before 
using any approved AMOC on any airplane to which the AMOC applies, 
notify your appropriate principal maintenance inspector (PMI) or 
principal avionics inspector (PAI), as appropriate, or lacking a 
principal inspector, your local Flight Standards 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.
    (3) Reporting Requirements: For any reporting requirement in 
this AD, under the provisions of the Paperwork Reduction Act, the 
Office of Management and Budget (OMB) has approved the information 
collection requirements and has assigned OMB Control Number 2120-
0056.
