Airworthiness Directives; Raytheon Model Hawker 800XP Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to certain Raytheon Model Hawker 800XP airplanes, that 
requires installing jumper wires on the computer control switches to 
power the digital electronic engine control when overspeed protection 
is selected, and tying and stowing the jumper wires on the switches. 
The actions specified by this AD are intended to prevent loss of the 
overspeed protection function without the flightcrew's awareness, due 
to missing jumper wires, which could result in engine overspeed and 
possible uncommanded engine shutdown. This action is intended to 
address the identified unsafe condition.

DATES: Effective February 18, 2003.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of February 18, 2003.

ADDRESSES: The service information referenced in this AD may be 
obtained from Raytheon Aircraft Company, Department 62, PO Box 85, 
Wichita, Kansas 67201-0085. This information may be examined at the 
Federal Aviation Administration (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 Hawker 
800XP airplanes was published in the Federal Register on September 25, 
2002 (67 FR 60191). That action proposed to require installing jumper 
wires on the computer control switches to power the digital electronic 
engine control when overspeed protection is selected, and tying and 
stowing the jumper wires on the switches.

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.

Explanation of Editorial Change

    We have changed the service bulletin citation throughout this final 
rule to exclude the Service Bulletin/Kit Drawing Report Fax. (This form 
is intended to be completed by operators and submitted to the 
manufacturer to report compliance; however, this AD does not include 
such a requirement.)

Conclusion

    After careful review of the available data, the FAA has determined 
that air safety and the public interest require the adoption of the 
rule with the change previously described. The FAA has determined that 
this change will neither increase the economic burden on any operator 
nor increase the scope of the AD.

Cost Impact

    There are approximately 250 Model 800XP airplanes of the affected 
design in the worldwide fleet. The FAA estimates that 193 airplanes of 
U.S. registry will be affected by this AD. It will take approximately 5 
work hours per airplane for airplanes with two oxygen bottles, and 6 
work hours per airplane for airplanes with three oxygen bottles, to 
accomplish the required actions, at an average labor rate of $60 per 
work hour. The cost of required parts will be nominal. Based on these 
figures, the cost impact of the AD on U.S. operators is estimated to be 
$300 per airplane (for airplanes with two oxygen bottles) or $360 per 
airplane (for airplanes with three oxygen bottles).
    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.
