Airworthiness Directives; Raytheon Aircraft Company Beech Models 
A36, B36TC, and 58 Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
applies to certain Raytheon Aircraft Corporation (Raytheon) Beech 
Models A36, B36TC, and 58 airplanes. This AD requires you to inspect 
for misrouted rudder control cables; replace any worn or damaged guard 
pins; replace any pulley brackets that are damaged or worn; and replace 
any misrouted rudder control cables. Three reports of misrouted cables 
prompted this action. The actions specified by this AD are intended to 
correct the misrouted rudder control cable and consequent guard pin 
wear or fraying of the cables with loss of rudder control.

DATES: This AD becomes effective on January 5, 2001.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the regulations as of 
January 5, 2001.

ADDRESSES: You may get the service information referenced in this AD 
from Raytheon Aircraft Company, P.O. Box 85, Wichita, Kansas 67201-
0085; telephone: (800) 429-5372 or (316) 676-3140; on the Internet at

SUPPLEMENTARY INFORMATION:

Discussion

    What events have caused this AD? The FAA has received three reports 
of instances of misrouted cables in Raytheon Beech Models A36, B36TC, 
and 58 airplanes. In one instance, a report noted complete separation 
of the rudder cable. In another instance, a report noted fraying of the 
rudder cable.
    What are the consequences if the condition is not corrected? This 
condition could result in guard pin wear and separation or fraying of 
the cables with loss of rudder control.
    Has FAA taken any action to this point? 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 Beech Models A36, 
B36TC, and 58 airplanes. This proposal published in the Federal 
Register as a notice of proposed rulemaking (NPRM) on August 24, 2000 
(65 FR 51562). The NPRM proposed to require you to inspect for 
misrouted rudder control cables; replace any worn or damaged guard 
pins; replace any pulley brackets that are damaged or worn; and replace 
any misrouted rudder control cables.
    Was the public invited to comment? Interested persons were afforded 
an opportunity to participate in the making of this amendment. No 
comments were received on the proposed rule or the FAA's determination 
of the cost to the public.

The FAA's Determination

    What is FAA's final determination on this issue? After careful 
review of all available information related to the subject presented 
above, we have determined that air safety and the public interest 
require the adoption of the rule as proposed except for minor editorial 
corrections. We determined that these minor corrections:

--will not change the meaning of the AD; and
--will not add any additional burden upon the public than was already 
proposed.

Cost Impact

    How many airplanes does this AD impact? We estimate that this AD 
affects 842 airplanes in the U.S. registry.
    What is the cost impact of this AD on owners/operators of the 
affected airplanes? We estimate the following costs to accomplish the 
inspection:

Regulatory Impact

    Does this AD impact various entities? The regulations adopted 
herein 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. Therefore, it is determined that this final rule does not 
have federalism implications under Executive Order 13132.
    Does this AD involve a significant rule or regulatory action? For 
the reasons discussed above, I certify that this action (1) is not a 
``significant regulatory action'' under Executive Order 12866; (2) is 
not a ``significant rule'' under 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. A copy 
of the final evaluation prepared for this action is contained in the 
Rules Docket. A copy of it may be obtained by contacting the Rules 
Docket at the location provided under the caption ADDRESSES.

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

    (e) Can I comply with this AD in any other way? You may use an 
alternative method of compliance or adjust the compliance time if:
    (1) Your alternative method of compliance provides an equivalent 
level of safety; and
    (2) The Manager, Wichita Aircraft Certification Office (ACO), 
approves your alternative. Submit your request through an FAA 
Principal Maintenance Inspector, who may add comments and then send 
it to the Manager, Wichita ACO.

    Note: This AD applies to each airplane identified in paragraph 
(a) of this AD, regardless of whether it has been modified, altered, 
or repaired in the area subject to the requirements of this AD. For 
airplanes that have been modified, altered, or repaired so that the 
performance of the requirements of this AD is affected, the owner/
operator must request approval for an alternative method of 
compliance in accordance with paragraph (e) of this AD. The request 
should include an assessment of the effect of the modification, 
alteration, or repair on the unsafe condition addressed by this AD; 
and, if you have not eliminated the unsafe condition, specific 
actions you propose to address it.

    (f) Where can I get information about any already-approved 
alternative methods of compliance? Contact Paul C. DeVore, Aerospace 
Engineer, Wichita Aircraft Certification Office, FAA, 1801 Airport 
Road, Mid-Continent Airport, Wichita, Kansas 67209; telephone: (316) 
946-4142; facsimile: (316) 946-4407.
    (g) What if I need to fly the airplane to another location to 
comply with this AD? The FAA can issue a special flight permit under 
sections 21.197 and 21.199 of the Federal Aviation Regulations (14 
CFR 21.197 and 21.199) to operate your airplane to a location where 
you can accomplish the requirements of this AD.
    (h) Are any service bulletins incorporated into this AD by 
reference? Actions required by this AD must be done in accordance 
with Raytheon Mandatory Service Bulletin SB 27-3265, Issued: January 
2000. The director of the Federal Register approved this incor- 
poration by reference under 5 U.S.C. 552(a) and 1 CFR part 51. You 
can get copies from Raytheon Aircraft Company, P.O. Box 85, Wichita,
