[Docket No. 2003-NM-244-AD; Amendment 39-13661; AD 2004-12-02]
RIN 2120-AA64


Airworthiness Directives; Raytheon Model BAe.125 Series 800A, 
800A (C-29A), and 800B Airplanes; and Model Hawker 800 Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to certain Raytheon Model BAe.125 series 800A, 800A (C-29A), 
and 800B airplanes; and Model Hawker 800 airplanes, that requires a 
one-time inspection of certain wire bundles for discrepancies and 
related corrective action. This action is necessary to find and fix 
chafing and damage to the wire bundles, which could result in 
electrical arcing and heat damage in a potential fuel zone and possible 
fire or explosion in the fuel tank. This action is intended to address 
the identified unsafe condition.

DATES: Effective July 14, 2004.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of July 14, 2004.

ADDRESSES: The service information referenced in this AD may be 
obtained from Raytheon Aircraft Company, Department 62, 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 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 BAe.125 
series 800A, 800A (C-29A), and 800B airplanes; and Model Hawker 800 
airplanes was published in the Federal Register on March 25, 2004 (69 
FR 15264). That action proposed to require a one-time inspection of 
certain wire bundles for discrepancies and related corrective action.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been submitted on the proposed 
AD 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.

Cost Impact

    There are about 184 airplanes of the affected design in the 
worldwide fleet. We estimate that 110 airplanes of U.S. registry will 
be affected by this AD, that it will take about 1 work hour per 
airplane to accomplish the inspection, and that the average labor rate 
is $65 per work hour. Based on these figures, the cost impact of the 
inspection required by this AD on U.S. operators is estimated to be 
$7,150, or $65 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. 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 
ADDRESSES.
