# 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 that would revise an existing AD. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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:

This Airworthiness Directive (AD) was prompted by reports of loose rivets on frames C18 BIS and C19, which could result in a reduced structural integrity of the tail area.

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 June 11, 2009.

## Discussion

On March 15, 2007, we issued AD 2007-03-17, Amendment 39-14928 (72 FR 5923, February 8, 2007). That AD required actions intended to address an unsafe condition on the products listed above.

Since we issued AD 2007-03-17, EADS SOCATA revised the service bulletin used in the AD to change the applicability.

The Direction Générale de l'aviation Civile (DGAC), which is the aviation authority for France, has issued French AD No F-2005-132, dated August 3, 2005, (referred to after this as “the MCAI”) to correct an unsafe condition for the specified products. The MCAI states:

This Airworthiness Directive (AD) was prompted by reports of loose rivets on frames C18 BIS and C19, which could result in a reduced structural integrity of the tail area.
      ( print page 22126)    
This MCAI requires you to inspect the rivets on frames C18 BIS and C19, and, if necessary, apply corrective actions. You may obtain further information by examining the MCAI in the AD docket.

## Relevant Service Information

SOCATA has issued SOCATA TBM Aircraft Mandatory Service Bulletin  SB 70-129, dated June 2005; and SOCATA TBM Aircraft Mandatory Service Bulletin SB 70-129, AMENDMENT 1, dated February 2009. 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

We estimate that this proposed AD will affect 272 products of U.S. registry. We also estimate that it would take about 3 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 $300 per product.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $146,880, or $540 per product.

In addition, we estimate that any necessary follow-on actions would take about 15 work-hours and require parts costing $2,000 for a cost of $3,200 per product. We have no way of determining the number of products that may need these actions.

## 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

      - Air transportation
      - Aircraft
      - Aviation safety
      - Incorporation by reference
      - 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 removing Amendment 39-14928 (72 FR 5923, February 8, 2007), and adding the following new AD:

**SOCATA:**                                 Docket No. FAA-2006-26234; Directorate Identifier 2006-CE-064-AD.                            

## Comments Due Date

(a) We must receive comments by June 11, 2009.

## Affected ADs

(b) This AD revises AD 2007-03-17, Amendment 39-14928 (72 FR 5923, February 8, 2007).

## Applicability

(c) This AD applies to TBM 700 airplanes, serial numbers 1 through 345, certificated in any category.

## Subject

(d) Air Transport Association of America (ATA) Code 53: Fuselage.

## Reason

(e) The mandatory continuing airworthiness information (MCAI) states:

This Airworthiness Directive (AD) was prompted by reports of loose rivets on frames C18 BIS and C19, which could result in a reduced structural integrity of the tail area.

This MCAI requires you to inspect the rivets on frames C18 BIS and C19, and, if necessary, apply corrective actions. You may obtain further information by examining the MCAI in the AD docket.

## Actions and Compliance

(f) Unless already done, within the next 100 hours time-in-service (TIS) after the effective date of this AD or within the next 12 months after the effective date of this AD, whichever occurs later, and thereafter at intervals not to exceed 100 hours TIS, accomplish a detailed inspection of the area and apply corrective actions as necessary by doing all the applicable actions in accordance with the accomplishment instructions of either SOCATA TBM Aircraft Mandatory Service Bulletin SB 70-129, dated June 2005 or SOCATA TBM Aircraft Mandatory Service Bulletin SB 70-129, AMENDMENT 1, dated February 2009.

## FAA AD Differences

**NOTE:**                                 This AD differs from the MCAI and/or service information as follows: SOCATA revised the service bulletin used in AD 2007-03-17, Amendment  39-14928 (72 FR 5923, February 8, 2007). The revised service bulletin changes the applicability of the airplanes from what was in the original service bulletin. The MCAI has not been                                       ( print page 22127)                                    revised and allows the use of “Any subsequent approved revision of this document is acceptable” for service bulletin revisions. The FAA AD does not have a similar provision. This proposed revised AD will change the Applicability section based on the revised service bulletin.                            

## Other FAA AD Provisions

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

                                (1)                                 *Alternative Methods of Compliance (AMOCs):*                                 The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Albert Mercado, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106;                                 *telephone:*                                 (816) 329-4119;                                 *fax:*                                 (816) 329-4090. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO.                            

                                (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.
