Airworthiness Directives; Cirrus Design Corporation Models SR20
and SR22 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 Cirrus Design Corporation (CDC) Models SR20 and SR22 airplanes.
This proposed AD would require you to inspect and, as necessary, adjust
the aileron and rudder rigging and would require you to modify,
inspect, and, as necessary, adjust the rudder-aileron interconnect
system. This proposed AD results from an on-the-ground jamming of the
aileron and rudder controls on a Model SR20 airplane, which resulted in
loss of rudder and aileron flight controls. We are proposing this AD to
prevent the possibility of jamming of the rudder-aileron interconnect
system, which may result in loss of rudder and aileron flight controls.

DATES: We must receive comments on this proposed AD by August 20, 2007.

proposed AD:

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-
2007-28246; Directorate Identifier 2007-CE-048-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://dms.dot.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 received notification from CDC of an on-the-ground jamming of
the aileron and rudder controls under full rudder and aileron cross
control inputs on a Model SR20 airplane. During a turn from the taxiway
onto the runway for takeoff, the pilot applied full rudder and full
opposite aileron for a turn with a crosswind. He then found he could no
longer move the controls. Subsequent examination of the airplane
revealed the rudder-aileron interconnect system had become locked
between the two control cables.
    This condition, if not corrected, could result in the possible
jamming of the rudder-aileron interconnect system, which may result in
loss of rudder and aileron flight controls.

Relevant Service Information

    We have reviewed CDC Service Bulletin No. SB 2X-27-14 R1, Issued:
May 9, 2007, Revised: May 24, 2007.
    The service information describes procedures for inspecting the
aileron and rudder rigging and modifying, inspecting, and adjusting, as
necessary, the rudder interconnect system.

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 inspect and, as necessary, adjust the aileron and
rudder rigging, and would require you to modify, inspect, and, as
necessary, adjust the rudder-aileron interconnect system.
    This proposed AD increases mechanical clearances within the rudder-
aileron interconnect system and ensures correct rigging/adjustment of
the ailerons, the rudder, and the rudder-aileron interconnect.

Costs of Compliance

    We estimate that this proposed AD would affect 2,387 airplanes in
the U.S. registry.
    We estimate the following costs to do the proposed inspections,
modification, and any adjustments that may be necessary based on the
results of the proposed inspections:

----------------------------------------------------------------------------------------------------------------
                                                                                 Total cost per   Total cost on
                          Labor cost                              Parts cost        airplane      U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $80 per hour = $80.............................             $18              $98         $233,926
----------------------------------------------------------------------------------------------------------------


    Note: CDC will provide warranty credit to the extent noted in
Service Bulletin No. SB 2X-27-14 R1, Issued May 9, 2007, Revised May
24, 2007.

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

[[Page 34199]]

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://dms.dot.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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Cirrus Design Corporation: Docket No. FAA-2007-28246; Directorate
Identifier 2007-CE-048-AD.

Comments Due Date

    (a) We must receive comments on this airworthiness directive
(AD) action by August 20, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Model SR20 airplanes, serial numbers (SN)
1005 through 1796, and Model SR22 airplanes, SN 0002 through 2333,
SN 2335 through 2419, and SN 2421 through 2437, that are
certificated in any category.

Unsafe Condition

    (d) This AD results from an on-the-ground jamming of the aileron
and rudder controls on a Model SR20 airplane. We are issuing this AD
to prevent the possibility of jamming of the rudder-aileron
interconnect system, which may result in loss of rudder and aileron
flight controls.
