Start Preamble

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (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) issued 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:

The Airworthiness Limitations Section of the Aircraft Maintenance Manual (AMM) applicable to the British Aerospace Jetstream 3200 has been revised. Some lives have been amended and new lives introduced. Compliance with these requirements is necessary to maintain airworthiness.

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

SUPPLEMENTARY INFORMATION:

Streamlined Issuance of AD

The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. This streamlined process will allow us to adopt MCAI safety requirements in a more efficient manner and will reduce safety risks to the public. This process continues to follow all FAA AD issuance processes to meet legal, economic, Administrative Procedure Act, and Federal Register requirements. We also continue to meet our technical decision-making responsibilities to identify and correct unsafe conditions on U.S.-certificated products.

This proposed AD references the MCAI and related service information that we considered in forming the engineering basis to correct the unsafe condition. The proposed AD contains text copied from the MCAI and for this reason might not follow our plain language principles.

Comments Invited

We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2006-26284; Directorate Identifier 2006-CE-68-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments.

We will post all comments we receive, without change, to http://dms.dot.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD.

Discussion

The Civil Aviation Authority (CAA), which is the airworthiness authority for the United Kingdom, has issued AD No. G-2004-0024, Issue Date: September 22, 2004, European Aviation Safety Agency (EASA) approved on September 16, 2004, under approval number 2004-9648 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

The Airworthiness Limitations Section of the Aircraft Maintenance Manual (AMM) applicable to the British Aerospace Jetstream 3200 has been revised. Some lives have been amended and new lives introduced. Compliance with these requirements is necessary to maintain airworthiness.

The MCAI requires:

From the effective date of this Airworthiness Directive (AD), comply with the requirements of BAE Jetstream Series 3200 Aircraft Maintenance Manual, Chapter 05-10-05, Airworthiness Limitations Description and Operation Section,* Revision 14 or later EASA approved revision.

* Only the structural fatigue tasks are mandated by this AD, the following tasks are not addressed by this AD: All the tasks recorded in Tables 2, 4, 5 and 8. Together Start Printed Page 11301with the Table No 3—task 27-70-000 Gust lock system.

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

Relevant Service Information

British Aerospace has issued Aircraft Maintenance Manual 05-10-05 001—AIRWORTHINESS LIMITATIONS—DESCRIPTION AND OPERATION—BAe Jetstream 32, dated January 11, 2006, for Recurring Mandatory Inspections and Maintenance Actions. The actions described in this AMM are intended to correct the unsafe condition identified in the MCAI.

This version of the above-referenced document is a later EASA-approved version than that referenced 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 described in a separate paragraph of the proposed AD. These requirements, if ultimately adopted, will take precedence over the actions copied from the MCAI.

Costs of Compliance

Based on the service information, we estimate that this proposed AD would affect about 20 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the proposed AD (inserting the document into the Airworthiness Limitations Section of the Instructions for Continued Airworthiness or other FAA-approved maintenance document). 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 $1,600, or $80 per product.

We have no way of determining the costs associated with having to replace certain parts at an earlier time due to reduced life limits.

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.

FAA AD Differences

Note:

This AD differs from the MCAI and/or service information as follows:

(1) The MCAI requires you to comply with a version of a maintenance manual that changes life limits. The FAA requires such changes through a change to the Airworthiness Limitations Section of the Instructions for Continued Airworthiness or other FAA-approved maintenance document, and the FAA is mandating this through this AD.

(2) We added information in paragraph (f) that allows the owner/operator to insert this information into the Airworthiness Limitations Section of the Instructions for Continued Airworthiness or other FAA-approved maintenance document. Without this information, a licensed mechanic would be required to do the action.

Other FAA AD Provisions

(g) The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Staff, FAA, Small Airplane Directorate, ATTN: Taylor Martin, Aerospace Engineer, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4138; fax: (816) 329-4090, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

(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.
