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.
     Fax: (202) 493-2251.

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        airplane      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.

Unsafe Condition

    (d) This AD results from two reports of accidents where reversed 
elevator control rigging was a factor. We are issuing 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 failure could lead to loss of 
control.
