Airworthiness Directives; Raytheon (Beech) Model 400A and 400T
Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain Raytheon (Beech) Model 400A and 400T series
airplanes, that requires a one-time inspection to detect incorrect
wiring of the engine fire extinguisher bottle squibs, and corrective
action, if necessary. It also requires a modification to the wiring and
the addition of wire harness and bottle labeling for future reference.
This amendment is prompted by reports of incorrect wiring of the engine
fire extinguisher bottle squibs. The actions specified by this AD are
intended to prevent failure of the engine fire extinguisher bottle to
discharge, or discharge of the wrong engine fire extinguisher bottle.
DATES: Effective April 12, 2000.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of April 12, 2000.
ADDRESSES: The service information referenced in this AD may be
obtained from Raytheon Aircraft Company, Manager Service Engineering,
Beechjet/Premier Technical Support Department, P.O. Box 85, Wichita,

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 Raytheon (Beech) Model
400A and 400T series airplanes was published in the Federal Register on
December 6, 1999 (64 FR 68060). That action proposed to require a one-
time inspection to detect incorrect wiring of the engine fire
extinguisher bottle squibs, and corrective action, if necessary. It
also proposed to require a modification to the wiring and the addition
of wire harness and bottle labeling for future reference.
Comments
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.
Conclusion
The FAA has determined that air safety and the public interest
require the adoption of the rule as proposed.
Cost Impact
There are approximately 350 airplanes of the affected design in the
worldwide fleet. The FAA estimates that 310 airplanes of U.S. registry
will be affected by this AD.
It is estimated that it will take approximately 1 work hour per
airplane to accomplish the required inspection,
[[Page 12083]]
at an average labor rate of $60 per work hour. Based on these figures,
the cost impact of the inspection portion of the AD on U.S. operators
is estimated to be $18,600, or $60 per airplane.
It is estimated that it will take approximately 2 work hours per
airplane to accomplish the required modification, at an average labor
rate of $60 per work hour. Based on these figures, the cost impact of
the modification portion of the required AD on U.S. operators is
estimated to be $37,200, or $120 per airplane.
Based on these figures, the cost impact of the AD on U.S. operators
is estimated to be $55,800, or $180 per airplane.
The cost impact figures discussed above are 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. However, the FAA has been advised
that manufacturer warranty remedies are available for labor costs
associated with accomplishing the actions required by this AD.
Therefore, the future economic cost impact of this rule on U.S.
operators may be less than the cost impact figure indicated above.
Regulatory Impact
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.
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
