PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 1649 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 2008–0026, dated February 12, 2008 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Several cases of corrosion and damage on the Down Drive Shafts (DDS), between the Down Drive Gear Box (DDGB) and the Input Gear Box (IPGB), on all 10 Flap Tracks (5 per wing), have been reported by AIRBUS Long Range Operators. Investigations have revealed that corrosion and wear due to absence of grease in the spline interfaces could cause [DDS] disconnection which could result in a free movable flap surface, potentially leading to aircraft asymmetry or even flap detachment. Emergency Airworthiness Directive (EAD) 2007–0222–E mandated on all aircraft older than 6 years since AIRBUS original delivery date of the aircraft, an initial inspection of all DDS and IPGB for corrosion and wear detection in order to replace any damaged part. Revision 1 of EAD 2007–0222–E aimed for clarifying the compliance instructions. [EASA AD 2008–0026] supersedes the EAD 2007–0222R1–E and mandates repetitive inspections every 6 years for all the fleet. The corrective actions include replacing damaged parts before next flight. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued Service Bulletins A330–27–3151, A330–27–3152, A340– 27–4151, A340–27–4152, and A340–27– 5040; all dated August 9, 2007. 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 E:\FR\FM\13JAP1.SGM 13JAP1 1650 Federal Register / Vol. 74, No. 8 / Tuesday, January 13, 2009 / Proposed Rules 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 41 products of U.S. registry. We also estimate that it would take about 65 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Required parts would cost about $0 per product. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $213,200, or $5,200 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. Airbus: Docket No. FAA–2009–0003; Directorate Identifier 2007–NM–251–AD. Regulatory Findings Comments Due Date 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. (a) We must receive comments by February 12, 2009.

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: Several cases of corrosion and damage on the Down Drive 
Shafts (DDS), between the Down Drive Gear Box (DDGB) and the Input Gear 
Box (IPGB), on all 10 Flap Tracks (5 per wing), have been reported by 
AIRBUS Long Range Operators. Investigations have revealed that 
corrosion and wear due to absence of grease in the spline interfaces 
could cause [DDS] disconnection which could result in a free movable 
flap surface, potentially leading to aircraft asymmetry or even flap 
detachment.The proposed AD would require actions that are intended to 
address the unsafe condition described in the MCAI.

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 2008-0026, dated February 12, 2008 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    Several cases of corrosion and damage on the Down Drive Shafts 
(DDS), between the Down Drive Gear Box (DDGB) and the Input Gear Box 
(IPGB), on all 10 Flap Tracks (5 per wing), have been reported by 
AIRBUS Long Range Operators.
    Investigations have revealed that corrosion and wear due to 
absence of grease in the spline interfaces could cause [DDS] 
disconnection which could result in a free movable flap surface, 
potentially leading to aircraft asymmetry or even flap detachment.
    Emergency Airworthiness Directive (EAD) 2007-0222-E mandated on 
all aircraft older than 6 years since AIRBUS original delivery date 
of the aircraft, an initial inspection of all DDS and IPGB for 
corrosion and wear detection in order to replace any damaged part.
    Revision 1 of EAD 2007-0222-E aimed for clarifying the 
compliance instructions.
    [EASA AD 2008-0026] supersedes the EAD 2007-0222R1-E and 
mandates repetitive inspections every 6 years for all the fleet.

The corrective actions include replacing damaged parts before next 
flight. You may obtain further information by examining the MCAI in the 
AD docket.

Relevant Service Information

    Airbus has issued Service Bulletins A330-27-3151, A330-27-3152, 
A340-27-4151, A340-27-4152, and A340-27-5040; all dated August 9, 2007. 
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

[[Page 1650]]

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 41 products of U.S. registry. We also estimate that 
it would take about 65 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Required parts would cost about $0 per product. Based on 
these figures, we estimate the cost of the proposed AD on U.S. 
operators to be $213,200, or $5,200 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

The Proposed Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Airbus: Docket No. FAA-2009-0003; Directorate Identifier 2007-NM-
251-AD.

Comments Due Date

    (a) We must receive comments by February 12, 2009.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A330-200 and -300 series 
airplanes, and A340-200, -300, -500 and -600 series airplanes, 
certificated in any category; all certified models, all manufacturer 
serial numbers.

Subject

    (d) Air Transport Association (ATA) of America Code 27: Flight 
Controls.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    Several cases of corrosion and damage on the Down Drive Shafts 
(DDS), between the Down Drive Gear Box (DDGB) and the Input Gear Box 
(IPGB), on all 10 Flap Tracks (5 per wing), have been reported by 
AIRBUS Long Range Operators.
    Investigations have revealed that corrosion and wear due to 
absence of grease in the spline interfaces could cause [DDS] 
disconnection which could result in a free movable flap surface, 
potentially leading to aircraft asymmetry or even flap detachment.
    Emergency Airworthiness Directive (EAD) 2007-0222-E mandated on 
all aircraft older than 6 years since AIRBUS original delivery date 
of the aircraft, an initial inspection of all DDS and IPGB for 
corrosion and wear detection in order to replace any damaged part.
    Revision 1 of EAD 2007-0222-E aimed for clarifying the 
compliance instructions.
    [EASA AD 2008-0026] supersedes the EAD 2007-0222R1-E and 
mandates repetitive inspections every 6 years for all the fleet.

The corrective actions include replacing damaged parts before next 
flight.

Actions and Compliance

    (f) Unless already done, do the applicable inspections and 
corrective actions specified in paragraphs (f)(1) and (f)(2) of this 
AD in accordance with the instructions of the applicable service 
information specified in Table 1 of this AD.
