FAA AD Differences List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety 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. § 39.13 [Amended] Comments Due Date (a) We must receive comments by August 8, 2007. Other FAA AD Provisions Affected ADs (b) None. Applicability (c) This AD applies to Airbus Model A300– 600 series airplanes, all certified models, all serial numbers, certificated in any category. Subject (d) Time Limits/Maintenance Checks. pwalker on PROD1PC71 with NOTICES2 Reason (e) The mandatory continued airworthiness information (MCAI) states: The aim of this AD, is to mandate airworthiness requirements in structural maintenance in accordance with the requirements defined in the AIRBUS A300– 600 Airworthiness Limitations Items (ALI) document issue 11, referenced AI/SE–M2/ 95A.0502/06, approved by EASA on 31 May 2006. Issue 11 of this document (refer to the Summary of Changes chapter for more details) deals in particular with the introduction of new tasks and the reduction of threshold and interval of some ALI tasks. Some other clarifications are also brought to some tasks like for example the access, the applicability period or the applicability. This AD supersedes DGAC AD F–2004– 153, as it was mandating A300–600 ALI issue 9. The unsafe condition is fatigue cracking, damage, or corrosion in principal structural elements, which could result in reduced structural integrity of the airplane. Incorporating this revision into the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness is intended to ensure the continued structural integrity of these airplanes. VerDate Aug<31>2005 Note: This AD differs from the MCAI and/ or service information as follows: No differences. 16:43 Jul 06, 2007 Jkt 211001 (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM–116, FAA, ATTN: Tom Stafford, Aerospace Engineer, 1601 Lind Avenue, SW., Renton, Washington; telephone (425) 227–1622; fax (425) 227–1149; has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Before using any AMOC approved in accordance with § 39.19 on any airplane to which the AMOC applies, notify the appropriate principal inspector in the FAA Flight Standards Certificate Holding District Office. (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.

The MCAI states: To prevent the cockpit door windows separating from their frames, * * * The MCAI requires you to inspect the windscreen and cockpit door windows for signs of disbonding of the adhesive between the transparency and the composite window frame. If disbonding is evident, you must do the required modification. You may obtain further information by examining the MCAI in the AD docket. VerDate Aug<31>2005 16:43 Jul 06, 2007 Jkt 211001 FAA’s Determination and Requirements of the 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 this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Differences Between This Proposed 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 7 products of U.S. registry. We also estimate that it would take about 40 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 $50 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 costs. 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. PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 37125 operators to be $22,750, or $3,250 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.

Discussion

    The Civil Aviation Authority of New Zealand, which is the aviation 
authority for New Zealand, has issued AD DCA/750XL/10, dated March 29, 
2007 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:
    To prevent the cockpit door windows separating from their frames, * 
* *
    The MCAI requires you to inspect the windscreen and cockpit door 
windows for signs of disbonding of the adhesive between the 
transparency and the composite window frame. If disbonding is evident, 
you must do the required modification.
    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Pacific Aerospace Corporation, Ltd has issued Pacific Aerospace 
Limited Mandatory Service Bulletin PACSB/XL/024 (embodiment of 
modification PAC/XL/0276), dated April 18, 2007, and PAC Drawing No. 
11-03137 (undated). The actions described in this service information 
are intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the 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 this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed 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 7 products of U.S. registry. We also estimate that 
it would take about 40 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 $50 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 costs. 
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 $22,750, or $3,250 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.
