14 CFR Part 39
[Docket No. 95-NM-165-AD; Amendment 39-9733; AD 96-18-09]
RIN 2120-AA64
Airworthiness Directives; Beech (Raytheon) Model BAe 125-800A and
-1000A, and Model Hawker 800 and 1000 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain Beech (Raytheon) Model BAe 125-800A and -1000A,
and Model Hawker 800 and 1000 series airplanes, that requires
modification of the TKS metering pump in the airframe ice protection
system. This amendment is prompted by a report that the pump was found
fitted with silver plated wiring. The actions specified by this AD are
intended to ensure that silver plated wiring is removed from these
pumps; silver plated wiring carrying a direct current can ignite the
ice protection fluid (glycol) when exposed to it, which could result in
a possible fire hazard.
DATES: Effective October 9, 1996.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of October 9, 1996.
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 Office of the
Federal Register, 800 North Capitol Street, NW., suite 700, Washington,
DC.
FOR FURTHER INFORMATION CONTACT: Tim Backman, Aerospace Engineer,
Standardization Branch, ANM-113, FAA, Transport Airplane Directorate,

227-2797; fax (206) 227-1149.
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 (Raytheon) Model BAe
125-800A and -1000A, and Model Hawker 800 and 1000 series airplanes was
published in the Federal Register on May 13, 1996 (61 FR 21979). That
action proposed to require modification of the TKS metering pump in the
airframe ice protection system.
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.
Cost Impact
The FAA estimates that 23 airplanes of U.S. registry will be
affected by this AD, that it will take approximately 1 work hour per
airplane to accomplish the required actions, and that the average labor
rate is $60 per work hour.
[[Page 46543]]
Based on these figures, the cost impact of the AD on U.S. operators is
estimated to be $1,380, or $60 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 ``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:
96-18-09 Beech Aircraft Company (Formerly DeHavilland; Hawker
Siddeley; British Aerospace, PLC; Raytheon Corporate Jets, Inc.):
Amendment 39-9733. Docket 95-NM-165-AD.
Applicability: Model BAe 125-800A and -1000A, and Model Hawker
800 and 1000 series airplanes; on which Modification 257676A has not
been accomplished (reference Hawker Service Bulletin SB.30-61-7676A
or Aerospace Systems and Technology Service Bulletin S.B.30-25);
certificated in any category.
Note 1: This AD applies to each airplane identified in the
preceding applicability provision, regardless of whether it has been
otherwise 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.
Note 2: Beech (Raytheon) Model BAe 125-800B and BAe 125-1000B
series airplanes are similar in design to the airplanes that are
subject to the requirements of this AD and, therefore, also may be
subject to the unsafe condition addressed by this AD. However, as of
the effective date of this AD, those models are not type
certificated for operation in the United States. Airworthiness
authorities of countries in which the Model BAe 125-800B and BAe
125-1000B series airplanes are approved for operation should
consider adopting corrective action, applicable to those models,
that is similar to the corrective action required by this AD.
Compliance: Required as indicated, unless accomplished
previously.
To ensure that silver plated wiring is removed from the TKS
metering pump and a possible fire hazard eliminated, accomplish the
following:
(a) Within 3 months after the effective date of this AD, modify
the TKS metering pump in the airframe ice protection system in
accordance with Hawker Service Bulletin SB.30-61-7676A, dated
February 15, 1995.
(b) As of the effective date of this AD, no person shall install
on any airplane a TKS metering pump, having part number XA9511E003-3
or XA9511E009, unless it has been modified in accordance with the
requirements of paragraph (a) of this AD.
(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, Standardization Branch, ANM-113,
FAA, Transport 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,
Standardization Branch, ANM-113.
Note 3: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Standardization Branch, ANM-113.
(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 modification shall be done in accordance with Hawker
Service Bulletin SB.30-61-7676A, dated February 15, 1995. (NOTE: The
issue date of this service bulletin is indicated only on Page 1; no
other page of the document is dated.) 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 Office of the Federal Register, 800 North
Capitol Street, NW., suite 700, Washington, DC.
(f) This amendment becomes effective on October 9, 1996.
Issued in Renton, Washington, on August 26, 1996.
