Federal Aviation Administration (FAA), Department of Transportation (DOT).
Notice of proposed rulemaking (NPRM).
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 airworthiness authority of another country. The proposed AD would require actions that are intended to address an unsafe condition described in the MCAI.
We must receive comments on this proposed AD by June 21, 2006.
Use one of the following addresses to comment on this proposed AD:
- DOT Docket Web site: Go to http://dms.dot.gov and follow the instructions for sending your comments electronically.
- Government-wide rulemaking Web site: Go to http://www.regulations.gov and follow the instructions for sending your comments electronically.
- Mail: Docket Management Facility; U.S. Department of Transportation, 400 Seventh Street, SW., Nassif Building, Room PL-401, Washington, DC 20590.

Streamlined Issuance of AD
The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. We are prototyping this process and specifically request your comments on its use. 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 existing AD issuance processes to meet legal, economic, Administrative Procedure Act, and Federal Register requirements. We also continue to follow our technical decision-making processes in all aspects to meet our responsibilities to determine 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.
The comment period for this proposed AD is open for 15 days. The comment period is reduced because the airworthiness authority and manufacturer have already published the documents on which we based our decision, making a longer comment period unnecessary.
We invite you to send any written data, views, or arguments regarding this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number, Docket No. FAA-2005-22420; Directorate Identifier 2005-CE-47-AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the proposed AD. We are also inviting comments, views, or arguments on the new MCAI process. We will consider all comments received by the closing date and may amend the proposed AD in light 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 concerning this proposed AD.
The Civil Aviation Authority (CAA), which is the airworthiness authority for the United Kingdom, has issued British Airworthiness Directive No. G-2004-0011, dated May 25, 2004 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states that that the aircraft manufacturer has identified several cases of corroded elevator final drive control rods. If not corrected corrosion of the interior surface could result in failure or collapse of the rod, resulting in loss of control or jamming of the elevator system. The MCAI requires an inspection of the internal surface of the elevator system final drive control rod and replacement if found corroded. You may obtain further information by examining the MCAI in the docket.
Relevant Service Information
BN-Group Ltd. has issued Britten-Norman Service Bulletin SB number 303, Issue 1, dated May 14, 2004. 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 is manufactured outside the United States and is type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral agreement. Pursuant to this bilateral airworthiness agreement, the State of Design's airworthiness authority has notified us of the unsafe condition described in the MCAI and service information referenced above. We have examined the airworthiness authority's findings, evaluated all pertinent information, and determined an unsafe condition exists and is likely to exist or develop on all products of this type design. We are issuing this proposed AD to correct the unsafe condition. Start Printed Page 32493
Differences Between the 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 a U.S. court of law. 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 proposed 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 91 products of U.S. registry. We also estimate that it would take about 5 workhours per product to do the action and that the average labor rate is $80 per workhour. Required parts would cost about $1,000 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 $127,400, or $1,400 per product.
Authority for This Rulemaking
Title 49 of the United States Code specifies 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 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.
We have 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 that the 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.
Examining the AD Docket
You may examine the AD docket that contains the proposed AD, the regulatory evaluation, any comments received, and other information on the Internet at http://dms.dot.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Office (telephone (800) 647-5227) is located at the street address stated in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.Start List of Subjects
