# 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:

several reports regarding an important corrosion on the bearings with propagation to the bracket-hinge of the rudder. This corrosion has been discovered after rudder removals. This condition, if left uncorrected, could result in the loss of the rudder control on the airplane.

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

# DATES:

We must receive comments on this proposed AD by March 29, 2007.

# SUPPLEMENTARY INFORMATION:

## Streamlined Issuance of AD

                    The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. The 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-2006-26692; Directorate Identifier 2006-CE-89-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 Direction générale de l'aviation civile (DGAC), which is the aviation authority for France, has issued AD No. F-2005-081, dated May 25, 2005, (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states that there have been:

several reports regarding an important corrosion on the bearings with propagation to the bracket-hinge of the rudder. This corrosion has been discovered after rudder removals. This condition, if left uncorrected, could result in the loss of the rudder control on the airplane.

The MCAI requires:

Within the next 100 flight hours or 3 months after the effective date of this AD, whichever occurs first, perform the REIMS AVIATION INDUSTRIES Service Bulletin No F406-57. These actions must be done in accordance with the manufacturer's technical publications.

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

## Relevant Service Information

REIMS AVIATION S.A. has issued REIMS AVIATION INDUSTRIES Service Bulletin No. F406-57, dated April 25, 2005. 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 6 work-hours per product to comply with the proposed AD. The average labor rate is $80 per work-hour. Required parts would cost about $100 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 $4,060, or $580 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:                          ( print page 8641)    

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

      - 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 

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

**REIMS AVIATION S.A.:**                                 Docket No. FAA-2006-26692; Directorate Identifier 2006-CE-89-AD                            

## Comments Due Date

(a) We must receive comments by March 29, 2007.

## Affected ADs

(b) None.

## Applicability

(c) This AD applies to Reims Aviation S.A. Model F406 airplanes, serial numbers F406-0001 through F406-0092, certificated in any category.

## Reason

(d) The mandatory continuing airworthiness information (MCAI) states that there have been:

several reports regarding an important corrosion on the bearings with propagation to the bracket-hinge of the rudder. This corrosion has been discovered after rudder removals. This condition, if left uncorrected, could result in the loss of the rudder control on the airplane.

## Actions and Compliance

(e) Unless already done, do the following actions:

(1) Within the next 100 hours time-in-service or 3 months after the effective date of this AD, whichever occurs first, and thereafter repetitively during a period not to exceed every 12 months, unless previously accomplished in the past 12 months, inspect the rudder brackets-hinge and bearings for corrosion and lubricate the rudder bearings in accordance with the accomplishment instructions of REIMS AVIATION INDUSTRIES Service Bulletin No. F406-57, dated April 25, 2005. If corrosion is found, replace these parts before further flight

(2) Initially lubricate the rudder bearings within 600 hours time-in-service or within 12 months, whichever occurs first, after the effective date of this AD, and repetitively thereafter at intervals not to exceed 12 months. During this step, remove the rudder to realize an optimum inspection and lubrication in accordance with the accomplishment instructions of Reims Aviation Industries Service Bulletin No. F406-57, dated April 25, 2005.

# Note 1:

We have established the repetitive inspection times of this AD so that they may coincide with annual inspections.

# Note 2:

We encourage you to put Reims temporary revision No. 4 into the maintenance program of the F406 airplane (chapter 5-10-01, page 17 of the maintenance manual).

##  FAA AD Differences

# Note 3:

This AD differs from the MCAI and/or service information as follows: We have added repetitive inspection requirements in the AD to coincide with the maintenance requirement in the service bulletin.

## Other FAA AD Provisions

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

(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Staff, FAA, ATTN: Mike Kiesov, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri, 64106; telephone: (816) 329-4144; 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.
