Airworthiness Directives; Hawker Beechcraft Model Hawker 800XP
Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Hawker Beechcraft Model Hawker 800XP airplanes. This
proposed AD would require doing an inspection of panel DA wiring for
clearance and for signs of chafing or exposed conductors, and repairing
or replacing the wires and cable ties if necessary. This proposed AD
results from reports of wire bundle interference in the DA panel,
chafed wire bundles, and exposed conductors. We are proposing this AD
to prevent chafing of wire bundles, which could cause an electrical
short and consequent loss of several functions essential for safe
flight and smoke or fire in the flight compartment and main cabin.
DATES: We must receive comments on this proposed AD by September 13,
2007.
ADDRESSES: Use one of the following addresses to submit comments on
this proposed AD.

Discussion
We have received reports of wire bundle interference in the DA
panel, chafed wire bundles, and exposed conductors, on Hawker
Beechcraft Model Hawker 800XP airplanes. These wire bundles consist of
wiring for various airplane systems (e.g., primary or secondary flight
displays, air data systems, communications, navigation, warnings, and
numerous other airplane systems). The cause has been attributed to
improper wire routing resulting from inadequate detailed assembly and
installation instructions during production of the airplanes. Chafing
of wire bundles, if not corrected, could cause an electrical short and
consequent loss of several functions essential for safe flight and
smoke or fire in the flight compartment and main cabin.
Relevant Service Information
We have reviewed Raytheon Service Bulletin SB 24-3772, dated
February 2006. The service information describes procedures for doing a
detailed inspection of panel DA wiring for clearance and for signs of
chafing or exposed conductors, and repairing or replacing the wires and
cable ties with new ones, if necessary. Accomplishing the actions
specified in the service information is intended to adequately address
the unsafe condition.
FAA's Determination and Requirements of the Proposed AD
We have evaluated all pertinent information and identified an
unsafe condition that is likely to exist or develop on other airplanes
of this same type design. For this reason, we are proposing this AD,
which would require accomplishing the actions specified in the service
information described previously, except as discussed under
``Difference Between the Proposed AD and Referenced Service
Information.''
Difference Between Proposed Rule and Referenced Service Information
Operators should note that, although the Accomplishment
Instructions of the referenced service information describe procedures
for submitting a sheet recording compliance with the service
information, this proposed AD would not require that action.
Costs of Compliance
There are about 438 airplanes of the affected design in the
worldwide fleet. This proposed AD would affect about 292 airplanes of
U.S. registry. The proposed inspection would take about 2 work hours
per airplane, at an average labor rate of $80 per work hour. Based on
these figures, the estimated cost of
[[Page 41466]]
the proposed AD for U.S. operators is $46,720, or $160 per airplane.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, Section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We have determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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.
For the reasons discussed above, I certify that the proposed
regulation:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket. See the
ADDRESSES section for a location to examine the regulatory evaluation.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 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. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
Hawker Beechcraft Corporation: Docket No. FAA-2007-28810;
Directorate Identifier 2007-NM-104-AD.
Comments Due Date
(a) The FAA must receive comments on this AD action by September
13, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Hawker Beechcraft Model Hawker 800XP
airplanes, certificated in any category; as identified in Raytheon
Service Bulletin SB 24-3772, dated February 2006.
Unsafe Condition
(d) This AD results from reports of wire bundle interference in
the DA panel, chafed wire bundles, and exposed conductors. We are
issuing this AD to prevent chafing of wire bundles, which could
cause an electrical short and consequent loss of several functions
essential for safe flight and smoke or fire in the flight
compartment and main cabin.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Inspection and Corrective Actions
(f) Within 600 flight hours or 12 months after the effective
date of this AD, whichever occurs first, do a detailed inspection of
panel DA wiring for clearance and for signs of chafing or exposed
conductors, in accordance with the Accomplishment Instructions of
Raytheon Service Bulletin SB 24-3772, dated February 2006. If any
wire is touching the panel, structure, or equipment, or if evidence
of chafing or exposed conductors exists, before further flight,
repair or replace the wires and cable ties with new ones, in
accordance with the service bulletin.
Note 1: For the purposes of this AD, a detailed inspection is:
``An intensive examination of a specific item, installation, or
assembly to detect damage, failure, or irregularity. Available
lighting is normally supplemented with a direct source of good
lighting at an intensity deemed appropriate. Inspection aids such as
mirror, magnifying lenses, etc., may be necessary. Surface cleaning
and elaborate procedures may be required.''
(g) Although Raytheon Service Bulletin SB 24-3772, dated
February 2006, specifies to submit certain information to the
manufacturer, this AD does not include that requirement.
Alternative Methods of Compliance (AMOCs)
(h)(1) The Manager, Wichita Aircraft Certification Office, FAA,
has the authority to approve AMOCs for this AD, if requested in
accordance with the procedures found in 14 CFR 39.19.
(2) To request a different method of compliance or a different
compliance time for this AD, follow the procedures in 14 CFR 39.19.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District Office (FSDO), or lacking a PI, your local
FSDO.
