RIN 2120-AA64
Airworthiness Directives; Raytheon Model Hawker 800XP 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 airplanes, that
requires installing jumper wires on the computer control switches to
power the digital electronic engine control when overspeed protection
is selected, and tying and stowing the jumper wires on the switches.
The actions specified by this AD are intended to prevent loss of the
overspeed protection function without the flightcrew's awareness, due
to missing jumper wires, which could result in engine overspeed and
possible uncommanded engine shutdown. This action is intended to
address the identified unsafe condition.
DATES: Effective February 18, 2003.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of February 18, 2003.
ADDRESSES: The service information referenced in this AD may be
obtained from Raytheon Aircraft Company, Department 62, PO Box 85,
Wichita, Kansas 67201-0085. This information may be examined at the
Federal Aviation Administration (FAA),

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 airplanes was published in the Federal Register on September 25,
2002 (67 FR 60191). That action proposed to require installing jumper
wires on the computer control switches to power the digital electronic
engine control when overspeed protection is selected, and tying and
stowing the jumper wires on the switches.
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.
Explanation of Editorial Change
We have changed the service bulletin citation throughout this final
rule to exclude the Service Bulletin/Kit Drawing Report Fax. (This form
is intended to be completed by operators and submitted to the
manufacturer to report compliance; however, this AD does not include
such a requirement.)
Conclusion
After careful review of the available data, the FAA has determined
that air safety and the public interest require the adoption of the
rule with the change previously described. The FAA has determined that
this change will neither increase the economic burden on any operator
nor increase the scope of the AD.
Cost Impact
There are approximately 250 Model 800XP airplanes of the affected
design in the worldwide fleet. The FAA estimates that 193 airplanes of
U.S. registry will be affected by this AD. It will take approximately 5
work hours per airplane for airplanes with two oxygen bottles, and 6
work hours per airplane for airplanes with three oxygen bottles, to
accomplish the required actions, at an average labor rate of $60 per
work hour. The cost of required parts will be nominal. Based on these
figures, the cost impact of the AD on U.S. operators is estimated to be
$300 per airplane (for airplanes with two oxygen bottles) or $360 per
airplane (for airplanes with three oxygen bottles).
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. The cost impact figures discussed
in AD rulemaking actions represent only the time necessary to perform
the specific actions actually required by the AD. These figures
typically do not include incidental costs, such as the time required to
gain access and close up, planning time, or time necessitated by other
administrative actions.
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

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:
2002-26-22 Raytheon Aircraft Company: Amendment 39-13011.
Docket 2001-NM-315-AD.
Applicability: Model Hawker 800XP airplanes, as listed in
Raytheon Service Bulletin SB 76-3480, dated August 2001, excluding
Service Bulletin/Kit Drawing Report Fax; 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 (b) 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 loss of the overspeed protection function without the
flightcrew's awareness, due to missing jumper wires, which could
result in engine overspeed and possible uncommanded engine shutdown,
accomplish the following:
Jumper Wire Installation
(a) Within 3 months or 300 flight hours after the effective date
of this AD, whichever occurs first, do the actions specified in
paragraphs (a)(1), (a)(2), and (a)(3) of this AD per Raytheon
Service Bulletin SB 76-3480, dated August 2001, excluding Service
Bulletin/Kit Drawing Report Fax.
(1) Install a four-inch jumper wire between terminals 1 and 3 on
the computer control switch ``NF.''
(2) Install a six-inch jumper wire between terminals 1 and 3 on
the computer control switch ``NG.''
(3) Tie and stow the jumper wires on the computer control
switches ``NF'' and ``NG'' using tie-wrap.
Alternative Methods of Compliance
(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. Operators shall submit their requests through an
appropriate FAA Principal Maintenance
[[Page 1525]]
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
(c) 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
(d) The actions shall be done in accordance with Raytheon
Service Bulletin SB 76-3480, dated August 2001, excluding Service
Bulletin/Kit Drawing Report Fax. 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, Department 62, PO Box 85, Wichita, Kansas
