DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2005-23319; Directorate Identifier 2005-CE-52-AD; 
Amendment 39-14663; AD 2006-13-10]
RIN 2120-AA64


Airworthiness Directives; Raytheon Aircraft Company 65, 90, 99, 
and 100 Series Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) that 
supersedes AD 92-07-05, which applies to certain Raytheon Aircraft 
Company (Raytheon) (formerly Beech) 65, 90, 99, and 100 series 
airplanes. AD 92-07-05 currently requires you to inspect the rudder 
trim tab for proper moisture drainage provisions, and if the correct 
drainage provisions do not exist, before further flight, modify the 
rudder trim tab. This AD results from receiving and evaluating new 
service information that requires the actions of AD 92-07-05 for the 
added serial numbers LJ-1281 through LJ-1732 for the Model C90A 
airplanes. This AD retains all the actions of AD 92-07-05 and adds 
serial numbers LJ-1281 through LJ-1732 for the Model C90A airplanes in 
the applicability section. We are issuing this AD to prevent water 
accumulation in the rudder trim tab, which could result in a change in 
the mass properties and possibly a lower flutter speed of the airplane. 
A lower airplane flutter speed could result in failure and loss of 
control of the airplane.

DATES: This AD becomes effective on August 7, 2006.
    As of August 7, 2006, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in the 
regulation.

ADDRESSES: For service information identified in this AD, contact 
Raytheon Aircraft Company, P.O. Box 85, Wichita, Kansas 67201-0085; 
telephone: (800) 429-5372 or (316) 676-3140.

SUPPLEMENTARY INFORMATION:

Discussion

    On January 31, 2006, 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 Raytheon 65, 90, 99, and 100 series airplanes. 
This proposal was published in the Federal Register as a notice of 
proposed rulemaking (NPRM) on February 6, 2006 (71 FR 6025). The NPRM 
proposed to supersede AD 92-07-05, Amendment 39-8201 (57 FR 8721, March 
12, 1992) and to add serial numbers LJ-1281 through LJ-1732 for the 
Model C90A airplanes in the applicability section. This AD will retain 
all the actions of AD 92-07-05 for inspecting and modifying the rudder 
trim tab for correct drainage provisions.

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 2,407 airplanes in the U.S. 
registry.
    We estimate the following costs to do the inspection:

----------------------------------------------------------------------------------------------------------------
                                                            Total cost per
             Labor cost                    Parts cost          airplane         Total cost on U.S.  operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $80 = $80............  Not Applicable.......             $80  2,407 x $80 = $192,560.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary modification of 
the rudder trim tab to provide the correct drainage provisions that 
would be required based on the results of this inspection. We have no 
way of determining the number of airplanes that may need this 
modification:

------------------------------------------------------------------------
                                                          Total cost per
              Labor cost                   Parts cost        airplane
------------------------------------------------------------------------
1 work-hour x $80 = $80...............             $25             $105
------------------------------------------------------------------------

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-2005-23319; Directorate Identifier 2005-CE-52-AD'' in your 
request.

    (2) Group 2: Model C90A, serial numbers LJ-1281 through LJ-1732.

Unsafe Condition

    (d) This AD results from receiving and evaluating new service 
information that requires the actions of AD 92-07-05 for the added 
serial numbers LJ-1281 through LJ-1732 for the Model C90A airplanes. 
The actions specified in this AD are intended to prevent water 
accumulation in the rudder trim tab, which could result in a change 
in the mass properties and possibly a lower flutter speed of the 
airplane. A lower airplane flutter speed could result in failure and 
loss of control of the airplane.
