RIN 2120-AA64


Airworthiness Directives; Raytheon Model BAe.125 Series 800A 
(Including C-29A and U-125 Variant) and 800B Airplanes; and Model 
Hawker 800 (Including U-125A Variant), and 800XP 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 (including C-
29A and U-125 variant) and 800B airplanes; and Model Hawker 800 
(including U-125A variant) and 800XP airplanes; that requires a 
functional test of the engine fire extinguishing wiring for the 
appropriate installation; verification of the correct wiring connector 
installation; correction of wiring if necessary; and installation of 
new marker bands. This action is necessary to prevent incorrect wiring 
of the engine fire extinguisher bottles, which could result in one or 
both fire extinguisher bottles being discharged into the wrong engine 
nacelle. This action is intended to address the identified unsafe 
condition.

DATES: Effective July 7, 2004.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of July 7, 2004.

ADDRESSES: The service information referenced in this AD may be 
obtained from Raytheon Aircraft Company, Department 62, P.O. Box 85,

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 (including C-29A and U-125 variant) and 800B airplanes; and 
Model Hawker 800 (including U-125A variant) and 800XP airplanes; was 
published in the Federal Register on February 26, 2004 (69 FR 8880). 
That action proposed to require a functional test of the engine fire 
extinguishing wiring for the appropriate installation; verification of 
the correct

[[Page 31000]]

wiring connector installation; correction of wiring if necessary; and 
installation of new marker bands.

Comments

    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.

Conclusion

    The FAA has determined that air safety and the public interest 
require the adoption of the rule as proposed.

Cost Impact

    There are approximately 615 airplanes of the affected design in the 
worldwide fleet. The FAA estimates that 430 airplanes of U.S. registry 
will be affected by this AD, that it will take approximately 2 work 
hours per airplane to accomplish the required actions, and that the 
average labor rate is $65 per work hour. Required parts will cost 
approximately $20 per airplane. Based on these figures, the cost impact 
of the AD on U.S. operators is estimated to be $64,500, or $150 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. The manufacturer may cover the cost of 
replacement parts associated with this proposed AD, subject to warranty 
conditions. Manufacturer warranty remedies may also be available for 
labor costs associated with this AD. As a result, the costs 
attributable to the AD may be less than stated above.

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.
