[Docket No. 2000-CE-25-AD; Amendment 39-12244; AD 2001-11-03]
RIN 2120-AA64


Airworthiness Directives; Raytheon Aircraft Company Beech Models 
F33A, A36, B36TC, 58/58A, C90A, B200, and 1900D Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
applies to certain Raytheon Aircraft Company (Raytheon) Beech Models 
F33A, A36, B36TC, 58/58A, C90A, B200, and 1900D airplanes equipped with 
a KA-33 cooling blower. This AD requires you to incorporate certain 
electrical parts to protect cooling blowers. This AD is the result of 
several reports of circuit breakers failing to protect cooling blowers 
on the affected airplanes. The actions specified by this AD are 
intended to protect the blower motor circuit and reduce the possibility 
of emission of smoke or a burning odor into the cockpit or passenger 
compartment as a result of a failed or seized blower motor.

DATES: This AD becomes effective on July 20, 2001.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the regulations as of July 
20, 2001.

ADDRESSES: You may get the service information referenced in this AD 
from the Raytheon Aircraft Company, P.O. Box 85, Wichita, Kansas 67201-
0085; telephone: (800) 429-5372 or (316) 676-3140. You may examine this 
information at the Federal Aviation Administration (FAA), Central 
Region, Office of the Regional Counsel, Attention: Rules Docket No. 
2000-CE-25-AD, 901 Locust, Room 506, Kansas City, Missouri 64106; or at 
the Office of the Federal Register, 800 North Capitol Street, NW., 
suite 700, Washington, DC.

SUPPLEMENTARY INFORMATION:

Discussion

What Events Have Caused This AD?

    The FAA has received several reports of blower motors failing, 
seizing, smoking, and producing a burning odor that enters the cabin 
and passenger compartment. These events are the result of the blower 
motor having circuit protection of more than 1 ampere. This amount of 
circuit protection does not prevent the blower motor from smoking and 
creating a burning odor should it fail or seize.

What Are the Consequences if the Condition Is Not Corrected?

    This condition could result in smoke or burning odor entering the 
cockpit or passenger compartments.

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 F33A, A36, B36TC, 58/58A, C90A, B200, and 
1900D airplanes equipped with a KA-33 cooling blower. This proposal was 
published in the Federal Register as a notice of proposed rulemaking 
(NPRM) on February 14, 2001 (66 FR 10226). The NPRM proposed to require 
you to incorporate certain electrical parts to protect cooling blowers.

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.

FAA's Determination and Provisions of This AD

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.

What Are the Differences Between the Service Bulletin and This AD?

    Raytheon specifies in the service information that you are to do 
this modification at the next scheduled inspection or before 6 months 
or 600 hours time-in-service, whichever comes first. We require you do 
the modification within the next 6 calendar months or 600 hours time-
in-service (TIS), whichever comes first, after the effective date of 
this AD. We cannot enforce a compliance time of ``at the next scheduled 
inspection.'' We believe that 6 calendar months or 600 hours TIS will 
give the owners/operators of the affected airplanes enough time to have 
the required actions done without compromising the safety of the 
airplanes. This will allow the owners/operators to work this 
modification into regularly scheduled maintenance.

Cost Impact

How Many Airplanes Does This AD Impact?

    We estimate that this AD affects 3,403 airplanes in the U.S. 
registry.

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.

    (h) 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 with a KA-33 cooling 
blower 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 (h) 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.

alternative methods of compliance? Contact Todd Dixon, Aerospace
