Airworthiness Directives; Raytheon Model BAe 125-800A Series 
Airplanes, and Model Hawker 800 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 BAe 125-800A series airplanes, and 
Model Hawker 800 and 800XP series airplanes, that requires modification 
of the rudder. This amendment is prompted by a report indicating that, 
due to the existing design of the rudder, overbias or overbalance of 
the rudder occurs during single engine handling. The actions specified 
by this AD are intended to prevent overbias or overbalance of the 
rudder, which could result in reduced controllability of the airplane.

DATES: Effective October 3, 1997.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of October 3, 1997.

ADDRESSES: The service information referenced in this AD may be 
obtained from Raytheon Aircraft Company, Manager Service Engineering, 
Hawker Customer Support Department, 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, Wichita 
Aircraft Certification Office, Small Airplane Directorate, 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: Larry Engler, Aerospace Engineer, 
Airframe Branch, ACE-118W, FAA, Wichita Aircraft Certification Office, 
Small Airplane Directorate, 1801 Airport Road, Room 100, Mid-Continent 
Airport, Wichita, Kansas 67209; telephone (316) 946-4122; fax (316)

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 Raytheon Model BAe 125-800A series 
airplanes, and Model Hawker 800 and 800XP series airplanes was 
published in the Federal Register on April 24, 1997 (62 FR 19950). That 
action proposed to require modification of the rudder.
    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 this rule as proposed.

Cost Impact

    There are approximately 295 Beech (Raytheon) Model BAe 125-800A 
series airplanes, and Model Hawker 800 and Hawker 800XP series 
airplanes of the affected design in the worldwide fleet. The FAA 
estimates that 190 airplanes of U.S. registry will be affected by this 
AD, that it will take approximately 8 work hours per airplane to 
accomplish the required actions, and that the average labor rate is $60 
per work hour. Required parts will cost approximately $300 per 
airplane. Based on these figures, the cost impact of the AD on U.S. 
operators is estimated to be $148,200, or $780 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.

Regulatory Impact

    The regulations adopted herein will not have substantial direct 
effects 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, in 
accordance with Executive Order 12612, it is determined that this final 
rule does not have sufficient federalism implications to warrant the 
preparation of a Federalism Assessment.
    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.


Sec. 39.13  [Amended]

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

97-18-07  Raytheon Aircraft Company (Formerly Beech, Raytheon 
Corporate Jets, British Aerospace, Hawker Siddley, et al.): 
Amendment 39-10117. Docket 96-NM-228-AD.

    Applicability: Model BAe 125-800A, and Model Hawker 800 and 
Hawker 800XP series airplanes; on which Raytheon Modification

[[Page 45710]]

25F017A&B (reference Raytheon Service Bulletin SB.55-36-25F017A&B) 
has not been installed; certificated in any category.

    Note 1: This AD applies to each airplane identified in the 
preceding applicability provision, regardless of whether it has been 
otherwise 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 (b) 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.
    Note 2: Raytheon Model BAe 125-800B series airplanes are similar 
in design to the airplanes that are subject to the requirements of 
this AD and, therefore, also may be subject to the unsafe condition 
addressed by this AD. However, as of the effective date of this AD, 
those models are not type certificated for operation in the United 
States. Airworthiness authorities of countries in which the Model 
BAe 125-800B series airplanes are approved for operation should 
consider adopting corrective action, applicable to those models, 
that is similar to the corrective action required by this AD.

    Compliance: Required as indicated, unless accomplished 
previously.
    To prevent overbias or overbalance of the rudder, which could 
result in reduced controllability of the airplane, accomplish the 
following:
    (a) Within 100 hours time-in-service or within 6 months after 
the effective date of this AD, whichever occurs first, modify the 
rudder in accordance with Raytheon Service Bulletin SB.55-36-
25F017A&B, dated April 15, 1996.
    (b) 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, Small Airplane Directorate. 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 3: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Wichita ACO.

    (c) 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.
    (d) The modification shall be done in accordance with Raytheon 
Service Bulletin SB.55-36-25F017A&B, dated April 15, 1996. This 
incorporation by reference was approved by the Director of the 
Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 
51. Copies may be obtained from Raytheon Aircraft Company, Manager 
Service Engineering, Hawker Customer Support Department, P.O. Box 
85, Wichita, Kansas 67201-0085. Copies may be inspected at the FAA, 
Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, 
Washington; or at the FAA, Wichita Aircraft Certification Office, 
Small Airplane Directorate, 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.
    (e) This amendment becomes effective on October 3, 1997.

    Issued in Renton, Washington, on August 25, 1997.
