# 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) 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: 

The backrest recline of pilot and copilot seats requires the removal of a “quick release pin” not correctly indicated in the AFM and not ready detectable by the passengers. Moreover the operation of removal the device is difficult. This cause difficulty or disables the access to the escapes of the cabin in case of emergency evacuation. 

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 April 9, 2007.

# 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-2007-27208; Directorate Identifier 2007-CE-010-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 Ente Nazionale per l'Aviazione Civile (ENAC), which is the aviation authority for Italy, has issued AD N. 2004-522, Rev. 0, dated December 20, 2004 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states: 

The backrest recline of pilot and copilot seats requires the removal of a “quick release pin” not correctly indicated in the AFM and not ready detectable by the passengers. Moreover the operation of removal the device is difficult. This cause difficulty or disables the access to the escapes of the cabin in case of emergency evacuation. 

The MCAI requires: 

Carry out the operational checks/inspection/modification: 

—Kit SB 128/A-1 applicable to aircraft model P68C. Serial numbers (S/N) 429, 434 and 435 are excluded; 

—Kit SB 128/A-2 applicable only to P68C aircraft with S/N 429, 434 and 435; 

—Kit SB 128/B applicable to aircraft model P68 Observer 2; 

—Kit SB 128/C applicable to aircraft model P68TC Observer; called for by the referenced Service Bulletin, in accordance with the procedures in there specified, within the terms set forth under “COMPLIANCE” of this AD. 

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

## Relevant Service Information 

                    Vulcanair S.p.A. has issued P68 Variants Mandatory Service Bulletin No. 128, dated October 12, 2004. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.                           ( print page 10621)    

## 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 15 products of U.S. registry. We also estimate that it would take about 2 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. 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 $2,400, or $160 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: 

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.
