E7-14857. 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:

This Airworthiness Directive (AD) results from one report about imperfect locking on ground of the upper access door opening interior handle which has enabled its opening without actuating unlocking knob.

If not corrected an inadvertent action on the handle without actuating the unlocking knob could lead to a door opening.

Investigations identified the unsafe condition resulting from interference between the window trim panel and the handle locking mechanism.

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 31, 2007.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Emergency Airworthiness (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

This Airworthiness Directive (AD) results from one report about imperfect locking on ground of the upper access door opening interior handle which has enabled its opening without actuating unlocking knob.

If not corrected an inadvertent action on the handle without actuating the unlocking knob could lead to a door opening.

Investigations identified the unsafe condition resulting from interference between the window trim panel and the handle locking mechanism.

Requirements of this AD are first, check for proper operation the locking handle and secondly modification of the window trim panel.

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

Relevant Service Information

EADS SOCATA has issued Mandatory Service Bulletin TBM Aircraft SB 70-150, dated May 2007. 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 23 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. Required parts would cost about $5 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 $3,795, or $165 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.

Reason

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

This Airworthiness Directive (AD) results from one report about imperfect locking on ground of the upper access door opening interior handle which has enabled its opening without actuating unlocking knob.

If not corrected an inadvertent action on the handle without actuating the unlocking knob could lead to a door opening.

Investigations identified the unsafe condition resulting from interference between the window trim panel and the handle locking mechanism.

Requirements of this AD are first, check for proper operation the locking handle and secondly modification of the window trim panel.

Actions and Compliance

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

(1) Before each flight after the effective date of this AD until the actions of paragraph (f)(2) of this AD have been done, check the handle locking using paragraph A of the accomplishment instructions in EADS SOCATA Mandatory TBM Aircraft Service Bulletin SB 70-150, dated May 2007. If any discrepancy is found, do the following before further flight until the modification in paragraph (f)(2) of this AD is done:

(i) Fabricate a placard using letter at least 1/8 inches in height with the words “FLIGHT ALLOWED WITH ONLY THE FLIGHT DECK SEATS OCCUPIED.”

(ii) Install this placard on the instrument panel within clear view of the pilot.

(iii) The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may do both the pre-flight checks and the placard requirements of this AD. Make an entry in the aircraft records showing compliance with this portion of the AD following section 43.9 of the Federal Aviation Regulations (14 CFR 43.9).

(2) Within the next 12 months after the effective date of this AD modify the window trim panel using paragraph B of the accomplishment instructions in EADS SOCATA Mandatory TBM Aircraft Service Bulletin SB 70-150, dated May 2007. This modification terminates the requirements of paragraph (f)(1) of this AD.
