14 CFR Part 39

[Docket No. FAA-2007-28246; Directorate Identifier 2007-CE-048-AD; 
Amendment 39-15367; AD 2008-03-16]
RIN 2120-AA64

 
Airworthiness Directives; Cirrus Design Corporation Models SR20 
and SR22 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Cirrus Design Corporation (CDC) Models SR20 and SR22 airplanes. This AD 
requires you to inspect the rudder, aileron, and rudder-aileron 
interconnect rigging; correct any out-of-rig condition; replace the 
attaching hardware for the rudder-aileron interconnect arm; and report 
any out-of-rig condition found. This AD results from a jamming of the 
aileron and rudder controls on a Model SR20 airplane, which resulted in 
loss of rudder and aileron flight controls. 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.

DATES: This AD becomes effective on March 11, 2008.
    On March 11, 2008, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in this 
AD.

SUPPLEMENTARY INFORMATION:

Discussion

    On November 28, 2007, we issued a proposal to amend part 39 of the 
Federal Aviation Regulations (14 CFR part 39) to include an AD that 
would apply to certain CDC Models SR20 and SR22 airplanes. This 
proposal was published in the Federal Register as a supplemental notice 
of proposed rulemaking (NPRM) on December 4, 2007 (72 FR 68108). The 
NPRM proposed to require you to inspect the rudder, aileron, and 
rudder-aileron interconnect rigging; correct any out-of-rig condition; 
replace the attaching hardware for the rudder-aileron interconnect arm; 
and require you to report any out-of-rig condition found.

Comments

    We provided the public the opportunity to participate in developing 
this AD. We received no comments on the proposal or on the 
determination of the cost to the public.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed 
except for minor editorial corrections. We have determined that these 
minor corrections:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Costs of Compliance

    We estimate that this AD affects 2,435 airplanes in the U.S. 
registry.
    We estimate the following costs to do the inspection of the rudder, 
aileron, and rudder-aileron interconnect rigging, and replacement of 
the attaching hardware for the rudder-aileron interconnect arm and RH 
aileron cable clamps:

----------------------------------------------------------------------------------------------------------------
                                                                                 Total cost per   Total cost on
                          Labor cost                              Parts cost        airplane      U.S. operators
----------------------------------------------------------------------------------------------------------------
1.5 work-hours x $80 per hour = $120.........................             $18             $138         $336,030
----------------------------------------------------------------------------------------------------------------

    CDC will provide warranty credit to the extent noted in Service 
Bulletin SB 2X-27-14 R3, Revised: October 10, 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 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 AD.

Regulatory Findings

    We have determined that this AD will not have federalism 
implications under Executive Order 13132. This AD will 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 this AD:
    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 summary of the costs to comply with this AD (and 
other information as included in the Regulatory Evaluation) and placed 
it in the AD Docket. You may get a copy of this summary by sending a 
request to us at the address listed under ADDRESSES. Include ``Docket 
No. FAA-2007-28246; Directorate Identifier 2007-CE-048-AD'' in your 
request.

reference, Safety.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the Federal Aviation Administration amends part 39 of the Federal 
Aviation Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. FAA amends Sec.  39.13 by adding the following new AD:

2008-03-16 Cirrus Design Corporation: Amendment 39-15367; Docket No. 
FAA-2007-28246; Directorate Identifier 2007-CE-048-AD.

Effective Date

    (a) This AD becomes effective on March 11, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Model SR20 airplanes, serial numbers (SN) 
1005 through 1861, 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 incident of jamming of the aileron 
and rudder controls on a Model SR20 airplane and the possibility of 
the occurrence on other airplanes. In addition, other Models SR20 
and SR22 airplanes have been found with misrigging of the flight 
controls that could lead to jamming. 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.
