Airworthiness Directives; EADS SOCATA Model TBM 700 Airplanes

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:

It has been discovered that a risk of mechanical interference exists in the movement of the emergency landing gear by-pass selector, due to an insufficient functional gap between a floor panel attachment lug and the landing gear control button.

This condition, if not corrected, causes mechanical interference which could result in a situation where, during emergency procedures, the landing gear cannot be extended.

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 August 7, 2008.

ADDRESSES: You may send comments by any of the following methods:

Federal eRulemaking Portal: Go to http:// www.regulations.gov. Follow the instructions for submitting comments.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical

Agent for the Member States of the European Community, has issued

Emergency AD No. 2008-0081-E, dated April 25, 2008, (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states:

It has been discovered that a risk of mechanical interference exists in the movement of the emergency landing gear by-pass selector, due to an insufficient functional gap between a floor panel attachment lug and the landing gear control button.

This condition, if not corrected, causes mechanical interference which could result in a situation where, during emergency procedures, the landing gear cannot be extended.

For the reasons described above, this EASA Emergency

Airworthiness Directive (AD) requires a check of the gap between the landing gear control button and the floor panel and, if the gap is found to be insufficient, modification of the floor panel.

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

Relevant Service Information

EADS SOCATA has issued Mandatory TBM Aircraft Service Bulletin SB 70-154, dated April 2008. 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 72 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour (no labor cost; work-hour warranty given by manufacturer until May 31, 2009).

Based on these figures, we estimate the cost of the proposed AD on

U.S. operators to be $5,760 or $80 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.

Comments Due Date

(a) We must receive comments by August 7, 2008.

Affected ADs

(b) None.

Applicability

(c) This AD applies to TBM 700 airplanes, serial numbers 364, 367, and 370 through 439, certificated in any category.

Subject

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

Fuselage.

Reason

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

It has been discovered that a risk of mechanical interference exists in the movement of the emergency landing gear by-pass selector, due to an insufficient functional gap between a floor panel attachment lug and the landing gear control button.

This condition, if not corrected, causes mechanical interference which could result in a situation where, during emergency procedures, the landing gear cannot be extended.

For the reasons described above, this EASA Emergency

Airworthiness Directive (AD) requires a check of the gap between the landing gear control button and the floor panel and, if the gap is found to be insufficient, modification of the floor panel.

Actions and Compliance

(f) For airplanes that have had the floor panel removed for maintenance or if it cannot be positively determined that the floor panel has not been removed at any time, do the following actions, unless already done:

(1) Before further flight after the effective date of this AD, inspect the gap between the landing gear control button and the floor panel. Do the inspection following paragraph A of the

Accomplishment Instructions in EADS SOCATA Mandatory TBM Aircraft

Service Bulletin SB 70-154, dated April 2008.

(2) If the gap is below the limits specified in paragraph A of

EADS SOCATA Mandatory TBM Aircraft Service Bulletin SB 70-154, dated

April 2008, before further flight after the inspection required in paragraph (f)(1) of this AD, modify the floor panel following paragraph C of the Accomplishment Instructions in EADS SOCATA

Mandatory TBM Aircraft Service Bulletin SB 70-154, dated April 2008.

(g) For airplanes in which it can be positively determined that the floor panel has not been removed at any time, within the next 30 days after the effective date of this AD, modify the floor panel following paragraph C of the Accomplishment Instructions in EADS

SOCATA Mandatory TBM Aircraft Service Bulletin SB 70-154, dated

April 2008.

FAA AD Differences

Note: This AD differs from the MCAI and/or service information as follows: No differences.

Other FAA AD Provisions

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