Airworthiness Directives; Beech (Raytheon) Model BAe 125 Series 
1000A and Model Hawker 1000 Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to certain Beech (Raytheon) Model BAe series 1000A and Model 
Hawker 1000 airplanes, that requires modifications of the thrust 
reversers. This amendment is prompted by a review of the certification 
analysis of the thrust reversers and by testing of the thrust 
reversers, which indicated that additional design features are 
necessary to prevent failure of the driver link and the inadvertent 
deployment of a thrust reverser during flight. The actions specified by 
this AD are intended to prevent inadvertent deployment of a thrust 
reverser during flight, which could result in reduced controllability 
of the airplane.

DATES: Effective December 11, 1996.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of December 11, 1996.

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 Office of the 
Federal Register, 800 North Capitol Street, NW., suite 700, Washington, 
DC.

FOR FURTHER INFORMATION CONTACT: Tim Backman, Aerospace Engineer, 
Standardization Branch, ANM-113, FAA, Transport Airplane Directorate,

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 Beech (Raytheon) Model BAe 
series 1000A and Model Hawker 1000 airplanes was published in the 
Federal Register on August 9, 1996 (61 FR 41537). That action proposed 
to require modifications of the thrust reversers.
    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

    The FAA estimates that 23 Beech (Raytheon) Model BAe series 100A 
and Model Hawker 1000 airplanes of U.S. registry will be affected by 
this AD, that it will take approximately 110 work hours per airplane 
(excluding time to gain access and functional testing) to accomplish 
the required actions, and that the average labor rate is $60 per work 
hour. Required parts will be provided by the manufacturer at no cost to 
operators. Based on these figures, the cost impact of the AD on U.S. 
operators is estimated to be $151,800, or $6,600 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:

96-22-03  Beech Aircraft Corporation (Formerly deHavilland; Hawker 
Siddeley; British Aerospace, plc; Raytheon Corporate Jets, Inc.): 
Amendment 39-9792. Docket 95-NM-167-AD.

    Applicability: Model BAe series 1000A and Model Hawker 1000 
airplanes; as identified in Hawker Service Bulletin SB.78-14-3691A, 
B&E, dated June 21, 1995; 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: Beech (Raytheon) Model BAe 125 series 1000B 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 series 1000B 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 inadvertent deployment of a thrust reverser during 
flight, and consequent reduced controllability of the airplane, 
accomplish the following:
    (a) Within 6 months after the effective date of this AD, modify 
the thrust reversers by accomplishing Modifications 253691 Part A, 
Part B, and Part E, in accordance with Hawker Service Bulletin 
SB.78-14-3691A, B&E, dated June 21, 1995.

    Note 3: The Hawker service bulletin references Rohr Service 
Bulletin PW300 78-8, dated June 21, 1995, as an additional source of 
service information for accomplishment of Modification 253691 Part 
E.

    (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, Standardization Branch, ANM-113, 
FAA, Transport 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, 
Standardization Branch, ANM-113.

    Note 4: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Standardization Branch, ANM-113.

    (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 modifications shall be done in accordance with Hawker 
Service Bulletin SB.78-14-3691 A,B&E, dated June 21, 1995. 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 Office of the Federal Register, 800 North 
Capitol Street, NW., suite 700, Washington, DC.
    (e) This amendment becomes effective on December 11, 1996.

    Issued in Renton, Washington, on October 15, 1996.
