DEPARTMENT OF TRANSPORTATION
14 CFR Part 39
[Docket No. 93-NM-202-AD; Amendment 39-8925; AD 94-11-09] 
 

Airworthiness Directives; Beech Aircraft Corporation Model 400A 
and 400T Airplanes 
AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to certain Beech Model 400A and 400T airplanes, that 
requires inspection to detect damage of the wire harness in the wheel 
well of the main landing gear (MLG), and modification, if necessary. 
This amendment is prompted by reports of damage to wire harnesses due 
to abrasion. The actions specified by this AD are intended to prevent 
loss of control of the fuel supply to the engine or loss of control of 
the retraction/extension system for the MLG and MLG door.

DATES: Effective July 7, 1994.

    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of July 7, 1994.

ADDRESSES: The service information referenced in this AD may be 
obtained from Beech Aircraft Corporation, Commercial Service 
Department, P.O. Box 85, Wichita, Kansas 67201-0085. This information 
may be examined at the Federal Aviation Administration (FAA), Transport 
Airplane Directorate, Rules Docket, 1601 Lind Avenue, SW., Renton, 
Washington; or at the FAA, Small Airplane Directorate, Wichita Aircraft 
Certification Office, 1801 Airport Road, Room 100, Mid-Continent 
Airport, Wichita, Kansas; or at the Office of the Federal Register, 800 
North Capitol Street, NW., suite 700, Washington, DC.

FOR FURTHER INFORMATION CONTACT: Larry Engler, Aerospace Engineer, 
Airframe Branch, ACE-115W, FAA, Small Airplane Directorate, Wichita 
Aircraft Certification Office, 1801 Airport Road, room 100, Mid-
Continent Airport, Wichita, Kansas 67209; telephone (316) 946-4122; fax 
(316) 946-4407.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to include an airworthiness 
directive (AD) that is applicable to certain Beech Model 400A and 400T 
airplanes was published in the Federal Register on February 9, 1994 (59 
FR 5965). That action proposed to require inspection to detect damage 
of the wire harness in the wheel well of the main landing gear (MLG), 
and modification, if necessary.
    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were submitted in response 
to the proposal or the FAA's determination of the cost to the public. 
The FAA has determined that air safety and the public interest require 
the adoption of the rule as proposed.
    There are approximately 59 Model 400A and 400T airplanes of the 
affected design in the worldwide fleet. The FAA estimates that 46 
airplanes of U.S. registry will be affected by this AD, that it will 
take approximately 2 work hours per airplane to accomplish the required 
actions, and that the average labor rate is $55 per work hour. Based on 
these figures, the total cost impact of the AD on U.S. operators is 
estimated to be $5,060, or $110 per airplane.
    The total cost impact figure discussed above is based on 
assumptions that no operator has yet accomplished any of the 
requirements of this AD action, and that no operator would accomplish 
those actions in the future if this AD were not adopted.
    The regulations adopted herein will not have substantial direct 
effects 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, in 
accordance with Executive Order 12612, it is determined that this final 
rule does not have sufficient federalism implications to warrant the 
preparation of a Federalism Assessment.
    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 final evaluation has been prepared for this action 
and it is contained in the Rules Docket. A copy of it may be obtained 
from the Rules Docket at the location provided under the caption 
ADDRESSES.

    Accordingly, pursuant to the authority delegated to me by the

airworthiness directive:

94-11-09 Beech: Amendment 39-8925, Docket 93-NM-202-AD.

    Applicability: Model 400A airplanes having serial numbers RK-1 
through RK-41 inclusive, and Model 400T airplanes having serial 
numbers TT-2 through TT-19 inclusive; certificated in any category.
    Compliance: Required as indicated, unless accomplished

    To prevent loss of control of the fuel supply to the engine or 
loss of control of the retraction/extension system for the main 
landing gear (MLG) and MLG door, accomplish the following:
    (a) Within 200 hours time-in-service after the effective date of 
this AD, perform a general visual inspection to detect damage of the 
wire harness in the wheel well of the MLG in accordance with 
Beechcraft Service Bulletin 2479, Revision 1, dated November 1993.
    (1) If no damage is found, no further action is required by this 
AD.
    (2) If damage is found, prior to further flight, modify the 
wiring in accordance with the service bulletin.

    Note 1: This service bulletin references Chapter 20-00 of the 
Aircraft Maintenance Manual and Air Force Technical Order P/N T.O. 
1-1A-14 for further service information regarding procedures for 
modification (removal and splicing) of the wiring.

    (b) An alternative method of compliance or adjustment of the 
compliance time that provides an acceptable level of safety may be 
used if approved by the Manager, Wichita Aircraft Certification 
Office (ACO), FAA, Small Airplane Directorate. Operators shall 
submit their requests through an appropriate FAA Principal 
Maintenance Inspector, who may add comments and then send it to the 
Manager, Wichita ACO.

    Note 2: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Wichita ACO.

sections 21.197 and 21.199 of the Federal Aviation Regulations (14 
CFR 21.197 and 21.199) to operate the airplane to a location where 
the requirements of this AD can be accomplished.
    (d) The inspection and modification shall be done in accordance 
with Beechcraft Service Bulletin 2479, Revision 1, dated November 
1993. (NOTE: The issue date of Revision 1 is indicated only on the
