14 CFR Part 39
[Docket No. 95-NM-42-AD; Amendment 39-9404; AD 95-21-17]
Airworthiness Directives; Raytheon Corporate Jets Model Hawker
1000 and BAe 125-1000A 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 1000 and BAe 125-1000A
series airplanes, that requires an inspection to detect damage to an
electrical cable loom (wire bundle). This amendment also requires tying
back the loom with a cable tie to the cable loom support bracket, and
repair, if necessary. This amendment is prompted by a report indicating
that damage had occurred to the electrical cable loom. The actions
specified by this AD are intended to prevent incorrect fault displays
in the cockpit and possible electrical systems failures, as a result of
damage to the electrical cable loom.
DATES: Effective November 17, 1995.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of November 17, 1995.
ADDRESSES: The service information referenced in this AD may be
obtained from Raytheon Corporate Jets, Inc., Customer Support
Department, Adams Field, P.O. Box 3356, Little Rock, Arkansas 72203.
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: William Schroeder, Aerospace Engineer,
Standardization Branch, ANM-113, FAA, Transport Airplane Directorate,
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (206)
227-2148; 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 Raytheon Model Hawker 1000
and BAe 125-1000A series airplanes was published in the Federal
Register on July 21, 1995 (60 FR 37607). That action proposed to
require a one-time detailed visual inspection to detect chafing damage
of a certain electrical cable loom located behind the right-hand
throttle box cover. That action also proposed tying back the loom with
a cable tie to the cable loom support bracket, if no damaged cable is
found.
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.
The FAA estimates that 19 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. Based on these figures, the total cost
impact of the AD on U.S. operators is estimated to be $1,140, or $60
per airplane.
The total 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 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,
[[Page 53869]]
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 USC 106(g), 40101, 40113, 44701.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:
95-21-17 Raytheon Corporate Jets, Inc. (Formerly de Havilland;
Hawker Siddeley; British Aerospace, plc): Amendment 39-9404. Docket
95-NM-42-AD.
Applicability: Model Hawker 1000 and BAe 125-1000A series
airplanes; as listed in Raytheon Service Bulletin SB 24-313, dated
December 19, 1994; 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 use the authority
provided in paragraph (b) of this AD to request approval from the
FAA. This approval may address either no action, if the current
configuration eliminates the unsafe condition; or different actions
necessary to address the unsafe condition described in this AD. Such
a request should include an assessment of the effect of the changed
configuration on the unsafe condition addressed by this AD. In no
case does the presence of any modification, alteration, or repair
remove any airplane from the applicability of this AD.
Compliance: Required as indicated, unless accomplished
previously.
To prevent incorrect fault displays in the cockpit and possible
electrical systems failures, accomplish the following:
(a) Within 6 months after the effective date of this AD, perform
a detailed visual inspection to detect chafing damage of the
electrical cable loom (wire bundle) behind the right-hand throttle
box cover, and perform continuity and insulation checks and system
functional tests, in accordance with Raytheon Service Bulletin SB
24-313, dated December 19, 1994.
(1) If no damage is found, prior to further flight, verify that
the arrangement of the cable loom is correct and, using a cable tie,
tie back the loom to the cable loom support bracket, in accordance
with the service bulletin.
(2) If any damage is found, prior to further flight, repair the
damaged loom, in accordance with a method approved by the Manager,
Standardization Branch, ANM-113, FAA, Transport Airplane
Directorate.
(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, 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 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Standardization Branch, ANM-113.
(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.
(d) The actions shall be done in accordance with Raytheon
Service Bulletin SB 24-313, dated December 19, 1994. 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 Corporate Jets, Inc.,
Customer Support Department, Adams Field, P.O. Box 3356, Little
Rock, Arkansas 72203. 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.
(e) This amendment becomes effective on November 17, 1995.
Issued in Renton, Washington, on October 10, 1995.
