Airworthiness Directives; Raytheon Model Hawker 800XP Series
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain Raytheon Model Hawker 800XP series airplanes,
that requires replacement of the fuel feed hose assemblies of the
auxiliary power unit (APU) with new hose assemblies. This amendment is
prompted by a report of the collapse of the inner casing of the fuel
feed hose that supplies fuel to the APU. The actions specified by this
AD are intended to prevent failure of the fuel feed hose assemblies,
which could result in fuel leakage and consequent risk of fire in the
aft equipment bay.
DATES: Effective December 18, 1998.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of December 18, 1998.
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,

Airplane Directorate, Wichita Aircraft Certification Office, 1801

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 Model Hawker
800XP series airplanes was published in the Federal Register on August
27, 1998 (63 FR 45773). That action proposed to require replacement of
the fuel feed hose assemblies of the auxiliary power unit (APU) with
new hose assemblies.
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
The FAA estimates that 11 airplanes of U.S. registry will be
affected by this AD, that it will take approximately 5 work hours per
airplane to accomplish the required replacement, and that the average
labor rate is $60 per work hour. Required parts will be provided by the
manufacturer at no cost to the operators. Based on these figures, the
cost impact of the replacement required by this AD on U.S. operators is
estimated to be $3,300, or $300 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.
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
[[Page 63397]]
``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.

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:
98-23-15 Raytheon Aircraft Company (Formerly Beech): Amendment 39-
10883. Docket 98-NM-195-AD.
Applicability: Model Hawker 800XP series airplanes, serial
numbers 258297 through 258304 inclusive, and 258307 through 258309
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 failure of the fuel feed hose assemblies, which could
result in fuel leakage and consequent risk of fire in the aft
equipment bay, accomplish the following:
(a) Within 300 flight hours or 3 months after the effective date
of this AD, whichever occurs later, replace the fuel feed hose
assemblies of the auxiliary power unit (APU) with new hose
assemblies in accordance with Raytheon Aircraft Service Bulletin
SB.49-3018, dated August 1997.
(b) If replacement fuel feed hose assemblies are not immediately
available for installation, shut down the APU and display warning
notices prohibiting use of the APU in accordance with Raytheon
Aircraft Service Bulletin SB.49-3018, dated August 1997, until the
replacement required by paragraph (a) of this AD is accomplished.
(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.
(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.
(e) The actions shall be done in accordance with Raytheon
Service Bulletin SB.49-3018, dated August 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 85,
Wichita, Kansas 67201-0085. Copies may be inspected at the FAA,
Transport Airplane Directorate, 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.
(f) This amendment becomes effective on December 18, 1998.
Issued in Renton, Washington, on November 4, 1998.
