DEPARTMENT OF TRANSPORTATION
Federal Aviation Administration
14 CFR Part 39
[Docket No. 96-NM-228-AD; Amendment 39-10117; AD 97-18-07]
RIN 2120-AA64
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.

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

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.

Acting Manager, Transport Airplane Directorate, Aircraft Certification
Service.
