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.

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

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

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.
