Airworthiness Directives; Raytheon Model Hawker 800A (U-125A) and 
Hawker 800XP Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to certain Raytheon Model Hawker 800A (U-125A) and Hawker 
800XP series airplanes, that requires inspecting the roller clearance 
in the nose landing gear drag stay and making

[[Page 77260]]

any necessary adjustments. This amendment is prompted by reports 
indicating multiple findings of roller clearances that are in excess of 
specifications. The actions specified by this AD are intended to 
prevent the inability to extend the nose landing gear, which could 
result in damage to the airplane upon landing.

DATES: Effective January 16, 2001.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of January 16, 2001.

ADDRESSES: The service information referenced in this AD may be 
obtained from Raytheon Aircraft Company, 9709 East Central, Wichita, 
Kansas 67206. 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, Wichita 
Aircraft Certification Office, 1801 Airport Road, Room 100, Mid-
Continent Airport, Wichita, Kansas; or at the Office of the Federal 
Register, 800 North Capitol Street, NW., suite 700, Washington, DC.

FOR FURTHER INFORMATION CONTACT: Paul C. DeVore, Aerospace Engineer, 
Systems and Propulsion Branch, ACE-116W, FAA, Wichita Aircraft 
Certification Office, 1801 Airport Road, Room 100, Mid-Continent 
Airport, Wichita, Kansas 67209; telephone (316) 946-4142; fax (316) 
946-4407.

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 800A 
(U-125A) and Hawker 800XP series airplanes was published in the Federal 
Register on August 8, 2000 (65 FR 48402). That action proposed to 
require inspecting the roller clearance in the nose landing gear drag 
stay and making any necessary adjustments.

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 85 airplanes of the affected design in the 
worldwide fleet. The FAA estimates that 50 airplanes of U.S. registry 
will be affected by this AD, that it will take approximately 7 work 
hours per airplane to accomplish the required inspection and any 
necessary adjustments, and that the average labor rate is $60 per work 
hour. Based on these figures, the cost impact of the AD on U.S. 
operators is estimated to be $21,000, or $420 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.

Adoption of the Amendment

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration amends part 39 of 
the Federal Aviation Regulations (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.


39.13  [Amended]

    2. Section 39.13 is amended by adding the following new 
airworthiness directive:

2000-24-25  Raytheon Aircraft Company:
    Amendment 39-12032. Docket 2000-NM-03-AD.

    Applicability: Model Hawker 800XP and Hawker 800A (U-125A) 
series airplanes, as specified in Raytheon Aircraft Service Bulletin 
SB 32-3274, dated August 1999; certificated in any category.

    Note 1: This AD applies to each airplane identified in the 
preceding applicability provision, regardless of whether it has been 
modified, altered, or repaired in the area subject to the 
requirements of this AD. For airplanes that have been modified, 
altered, or repaired so that the performance of the requirements of 
this AD is affected, the owner/operator must request approval for an 
alternative method of compliance in accordance with paragraph (c) of 
this AD. The request should include an assessment of the effect of 
the modification, alteration, or repair on the unsafe condition 
addressed by this AD; and, if the unsafe condition has not been 
eliminated, the request should include specific proposed actions to 
address it.

    Compliance: Required as indicated, unless accomplished 
previously.
    To prevent the inability to extend the nose landing gear due to 
excessive clearance of the roller in the drag stay rigging, which 
could result in damage to the airplane upon landing, accomplish the 
following:

Inspection and Adjustment

    (a) Within 50 hours time-in-service after the effective date of 
this AD: Remove the paint from the drag stay arm of the nose landing 
gear at its point of contact with the stop bolt, do a check of the 
roller clearances, and make any necessary adjustments, in accordance 
with the Accomplishment Instructions of Raytheon Aircraft Service 
Bulletin SB 32-3274, dated August 1999.
    (b) Airplanes which have had the 600-hour inspection specified 
in the Aircraft Maintenance Manual before the effective date of this 
AD or which will have the 600-hour inspection within 50 hours time-
in-service after the effective date of this AD are considered to be 
in compliance with paragraph (a) of this AD.

Alternative Methods of Compliance

    (c) An alternative method of compliance or adjustment of the 
compliance time that provides an acceptable level of safety may be 
used if approved by the Manager, Wichita Aircraft Certification 
Office (ACO), FAA. Operators shall submit their requests through an 
appropriate FAA Principal Maintenance Inspector, who may add 
comments and then send it to the Manager, Wichita ACO.

    Note 2: Information concerning the existence of approved 
alternative methods of

[[Page 77261]]

compliance with this AD, if any, may be obtained from the Wichita 
ACO.

Special Flight Permits

    (d) Special flight permits may be issued in accordance with 
sections 21.197 and 21.199 of the Federal Aviation Regulations (14 
CFR 21.197 and 21.199) to operate the airplane to a location where 
the requirements of this AD can be accomplished.

Incorporation by Reference

    (e) The actions shall be done in accordance with Raytheon 
Aircraft Service Bulletin SB 32-3274, dated August 1999. This 
incorporation by reference was approved by the Director of the
