Airworthiness Directives; Maule Aerospace Technology, Inc. Models

M-4, M-5, M-6, M-7, and M-8 Series 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 certain Maule Aerospace Technology, Inc. Models M-4, M-5, M-6, M-7, and

M-8 series airplanes. This proposed AD would require you to paint the top of the rear elevator control horn, the elevator control cable end attached to the top of the rear control horn, the bottom of the forward elevator control horn, and the elevator control cable end attached to the bottom of the forward control. This proposed AD would also require you to insert a supplement into your maintenance program (maintenance manual). This proposed AD results from two reports of accidents where reversed elevator control rigging was a factor. We are proposing this

AD to reduce the likelihood of a mechanic rigging the elevator controls backwards, which could result in elevator movement in the opposite direction from control input. This condition could lead to loss of control.

DATES: We must receive comments on this proposed AD by October 20, 2008.

ADDRESSES: Use one of the following addresses to comment on this proposed AD:

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

SUPPLEMENTARY INFORMATION:

Comments Invited

We invite you to send any written relevant data, views, or arguments regarding this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number, ``FAA- 2008-0892; Directorate Identifier 2008-CE-049-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the proposed

AD. We will consider all comments received by the closing date and may amend the proposed AD in light of those comments.

We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive concerning this proposed AD.

Discussion

We have received two reports of accidents where reversed elevator control rigging was a factor. We are proposing this AD to reduce the likelihood of a mechanic rigging the elevator controls backwards, which could result in elevator movement in the opposite direction from control input.

This condition, if not corrected, could result in loss of control.

Relevant Service Information

We have reviewed Maule Aerospace Technology, Inc. Mandatory Service

Bulletin No. 30, dated March 4, 2008.

The service information describes procedures for:

Painting the top of the rear elevator control horn and the elevator control cable end attached to the top of the rear control horn;

Painting the bottom of the forward elevator control horn and the elevator control cable end attached to the bottom of the forward control; and

Inserting a supplement in the maintenance program

(maintenance manual).

FAA's Determination and Requirements of the Proposed AD

We are proposing this AD because we evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This proposed AD would require you to paint the top of the rear elevator control horn, the elevator control cable end attached to the top of the rear control horn, the bottom of the forward elevator control horn, and the elevator control cable end attached to the bottom of the forward control. This proposed AD would also require you to insert a supplement into your maintenance program (maintenance manual).

Costs of Compliance

We estimate that this proposed AD would affect 1,765 airplanes in the U.S. registry.

We estimate the following costs to do the proposed modification:

Total cost per Total cost on

Labor cost

Parts cost

U.S. operators

1 work-hour x $80 per hour = $80.............................

$20

$100

$176,500

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 have 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 that the 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.

Examining the AD Docket

You may examine the AD docket that contains the proposed AD, the regulatory evaluation, any comments received, and other information on the Internet at http://www.regulations.gov; or in person at the Docket

Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Office (telephone (800) 647-5527) is located at the street address stated in the ADDRESSES section.

Comments will be available in the AD docket shortly after receipt.
