RIN 2120-AA64
Airworthiness Directives; Raytheon (Beech) Model 400A 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 airplanes, that
requires replacement of the fuel drain tube assembly in the aft
fuselage with a new, modified assembly. This amendment is prompted by a
report of chafing of the fuel tube assembly against the elevator
control cable due to inadequate clearance between the components. The
actions specified by this AD are intended to prevent chafing of the
fuel drain tube assembly, which could result in fuel leakage from the
fuel drain tube assembly and consequent risk of a fire.
DATES: Effective November 12, 1999.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of November 12, 1999.
ADDRESSES: The service information referenced in this AD may be
obtained from Raytheon Aircraft Company, Manager Service Engineering,
Hawker Customer Support 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.

Directorate, Wichita Aircraft Certification Office, 1801 Airport Road,

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 airplanes was published in the Federal Register on August 10, 1999
(64 FR 43314). That action proposed to require replacement of the fuel
drain tube assembly in the aft fuselage with a new, modified assembly.
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 92 airplanes of the affected design in the
worldwide fleet. The FAA estimates that 72 airplanes of U.S. registry
will be affected by this AD, that it will take approximately 8 work
hours per airplane to accomplish the required action, and that the
average labor rate is $60 per work hour. Required parts will cost
approximately $21 per airplane. Based on these figures, the cost impact
of the required AD on U.S. operators is estimated to be $36,072, or
$501 per airplane.
The 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.
Regulatory Impact
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.
[[Page 54518]]
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

Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends part 39 of
the Federal Aviation Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:
99-21-08 Raytheon Aircraft Company (Formerly Beech): Amendment 39-
11351. Docket 98-NM-280-AD.
Applicability: Model 400A airplanes, serial numbers RK-1 through
RK-92 inclusive, certificated in any category.
Note 1: This AD applies to each airplane identified in the
preceding applicability provision, 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 (c) 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 the unsafe condition has not been
eliminated, the request should include specific proposed actions to
address it.
Compliance: Required as indicated, unless accomplished
previously.
To prevent chafing of the fuel drain tube assembly, which could
result in fuel leakage from the fuel drain tube assembly and
consequent risk of fire, accomplish the following:
Replacement
(a) At the next scheduled inspection, but no later than 200
flight hours after the effective date of this AD, replace the
existing aft fuselage fuel drain tube assembly, part number (P/N)
128-920151-1, with a new, modified tube assembly, P/N 128-920237-1,
in accordance with Raytheon Aircraft Service Bulletin SB.28-3076,
dated October, 1997.
Spares
(b) As of the effective date of this AD, no person shall install
a fuel drain tube assembly, P/N 128-920151-1, on any airplane.
Alternative Methods of Compliance
(c) 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.
Special Flight Permits
(d) Special flight permits may be issued in accordance with
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.
Incorporation by Reference
(e) The replacement shall be done in accordance with Raytheon
Aircraft Service Bulletin SB.28-3076, dated October, 1997. This
incorporation by reference was approved by the Director of the
Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part
51. Copies may be obtained from Raytheon Aircraft Company, Manager
Service Engineering, Hawker Customer Support Department, P.O. Box
