Discussion

On April 24, 2008, we issued AD 2008–09–22, Amendment 39–15503 (73 FR 23939, May 1, 2008). That AD required actions intended to address an unsafe condition on the products listed above.

Since we issued AD 2008–09–22, the fuel airworthiness limitations have been revised. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2009–0146, dated July 3, 2009 (referred to after this

as ‘‘the MCAI ’’ ), to correct an unsafe condition for the specified products. The MCAI states:

Prompted by [an] accident * * *, the FAA published SFAR 88 (Special Federal Aviation Regulation 88). Subsequently, the Joint Aviation Authorities (JAA) recommended the application of a similar regulation to the National Aviation Authorities (NAA) of its member countries.

Under this regulation, all holders of type certificates for passenger transport aeroplanes with either a passenger capacity of 30 or more, or a payload capacity of 3 402 kg (7 500 lbs) or more, which have received their certification since 01 January 1958, are required to conduct a design review against explosion risks.

In August 2005, EASA published a policy statement on the process for developing instructions for maintenance and inspection of Fuel Tank System ignition source prevention (EASA D 2005/CPRO), that also included the EASA expectations with regard to compliance times of the corrective actions on the unsafe and the not unsafe part of the harmonised design review results.

Fuel Airworthiness Limitations arising from the required systems safety analysis are items that have been shown to have failure mode(s) associated with an ‘unsafe condition’ as defined in the FAA memo 2003–112–15 ‘SFAR 88—Mandatory Action Decision Criteria’. These are identified in Failure Conditions for which an unacceptable probability of ignition risk could exist if specific tasks and/or practices are not performed in accordance with the corrective action(s) developed by the TC [type certificate] holder.

To address these potential unsafe conditions, EASA issued AD 2007–0007, mandating the Fuel System Airworthiness Limitations, comprising maintenance and inspection tasks and Critical Design Configuration Control Limitations (CDCCL) that were, at that moment, defined in issue C of EADS–CASA document DT–0–C00– 05001. That document has now been revised and updated to issue D.

For the reasons described above, this EASA AD retains the requirements of AD 2007– 0007, which is superseded [and corresponds to FAA AD 2008–09–22], and requires the implementation of the revised Fuel Airworthiness Limitations contained in issue D of EADS–CASA document DT–0–C00– 05001 and accomplishment of related modifications. The required actions are retaining the limitations for fuel tank systems, adding thermal insulation to the air conditional compression system, applying double bonding connection on fuel tubes, and modifying the separation between the center wing electrical harness and fuel tubes. The application of double bonding connections on fuel tubes includes doing general visual inspections for damage of the inside of the fuel tanks, and corrective actions if necessary. The corrective actions include contacting EADS CASA for repair instructions and doing the repair. You may obtain further information by examining the MCAI in the AD docket.

We have changed Table 1 of this AD to fix a typographical error, which is specified in EADS CASA Component Maintenance Manual with Illustrated Parts List 28–21–12, Revision 003, dated June 15, 2007. The title page of that document specifies ‘‘Revision 002. ’’ The correct revision level is ‘‘Revision 003. ’’

Relevant Service Information

EADS CASA has issued the following service bulletins:


### 37341 Federal Register / Vol. 75, No. 124 / Tuesday, June 29, 2010 / Proposed Rules

• EADS CASA Service Bulletin SB– 235–21–18, dated August 2, 2007;

• EADS CASA Service Bulletin SB– 235–24–20, dated August 2, 2007; and

• EADS CASA Service Bulletin SB– 235–28–18, dated August 2, 2007.
EADS CASA has also issued CN–235/C– 295 Technical Document, DT–0–C00– 05001, Issue D, dated October 2008. 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 8 products of U.S. registry.

The actions that are required by AD 2008–09–22 and retained in this proposed AD take about 1 work-hour per product, at an average labor rate of $85 per work hour. Based on these figures, the estimated cost of the currently required actions is $85 per product.

We estimate that it would take about 90 work-hours per product, depending on airplane configuration, to comply with the new 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 $61,200, or $7,650 per product, depending on airplane configuration. 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. List of Subjects in 14 CFR Part 39

performed in accordance with the corrective action(s) developed by the TC [type certificate] holder.

‘‘ To address these potential unsafe conditions, EASA issued AD 2007–0007, mandating the Fuel System Airworthiness Limitations, comprising maintenance and inspection tasks and Critical Design Configuration Control Limitations (CDCCL) that were, at that moment, defined in issue C of EADSCASA document DT–0–C00– 05001. That document has now been revised and updated to issue D.

‘‘ For the reasons described above, this EASA AD retains the requirements of AD 2007–0007, which is superseded [and corresponds to FAA AD 2008–09–22], and requires the implementation of the revised Fuel Airworthiness Limitations contained in issue D of EADS–CASA document DT–0– C00–05001 and accomplishment of related modifications. ’’ The required actions are retaining the limitations for fuel tank systems, adding thermal insulation to the air conditional compression system, applying double bonding connection on fuel tubes, and modifying the separation between the center wing electrical harness and fuel tubes. The application of double bonding connections on fuel tubes includes doing general visual inspections for damage of the inside of the fuel tanks, and corrective actions if necessary. The corrective actions include contacting EADS CASA for repair instructions and doing the repair. You may obtain further information by examining the MCAI in the AD docket.

227–1149.

Before using any approved AMOC on any airplane to which the AMOC applies, notify your 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 (44 U.S.C. 3501 et seq. ), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120–0056.

Related Information
