14 CFR Part 39

[Docket No. FAA-2007-28810; Directorate Identifier 2007-NM-104-AD; 
Amendment 39-15226; AD 2007-21-08]
RIN 2120-AA64


Airworthiness Directives; Hawker Beechcraft Model Hawker 800XP 
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Hawker Beechcraft Model Hawker 800XP airplanes. This AD 
requires 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 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.

DATES: This AD becomes effective November 20, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of November 20, 
2007.

ADDRESSES: For service information identified in this AD, contact 
Hawker Beechcraft Corporation, 9709 East Central, Wichita, Kansas 
67206.

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain Hawker 
Beechcraft Model Hawker 800XP airplanes. That NPRM was published in the 
Federal Register on July 30, 2007 (72 FR 41465). That NPRM proposed to 
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.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed.

Costs of Compliance

    There are about 438 airplanes of the affected design in the 
worldwide fleet. This AD affects about 292 airplanes of U.S. registry. 
The required inspection takes about 2 work hours per airplane, at an 
average labor rate of $80 per work hour. Based on these figures, the 
estimated cost of this 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 AD will not have federalism 
implications under Executive Order 13132. This AD 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.
    For the reasons discussed above, I certify that this AD:
    (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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The Federal Aviation Administration (FAA) amends Sec.  39.13 by 
adding the following new airworthiness directive (AD):

2007-21-08 Hawker Beechcraft Corporation (formerly Raytheon Aircraft 
Company): Amendment 39-15226. Docket No. FAA-2007-28810; Directorate 
Identifier 2007-NM-104-AD.

Effective Date

    (a) This AD becomes effective November 20, 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.
