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 125 series 1000A and 
Model Hawker 1000 airplanes, that requires a one-time inspection for 
adequate clearances between, and damage to, the flap cables and 
turnbuckles, airbrakes cables and turnbuckles, and all other flight 
control cables and turnbuckles at keel subframe 15A; and various 
follow-on actions, if necessary. This amendment is prompted by reports 
of chafing due to insufficient clearance between the flaps turnbuckle 
and the subframe, and between the airbrakes cable and the subframe. The 
actions specified by this AD are intended to prevent such chafing, 
which could result in damage to the flaps turnbuckle and the airbrakes 
cable, and subsequent fraying or seizing of the flight control cables. 
These conditions, if not corrected, could result in restriction or loss 
of the flight controls.

DATES: Effective July 9, 1996.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of July 9, 1996.

ADDRESSES: The service information referenced in this AD may be 
obtained

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

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 
125 series 1000A and Model Hawker 1000 airplanes was published in the 
Federal Register on March 12, 1996 (61 FR 9959). That action proposed 
to require a one-time visual inspection for adequate clearances 
between, and/or damage to, the flap cables and turnbuckles, airbrakes 
cables and turnbuckles, and all other flight control cables and 
turnbuckles at keel subframe 15A (left-and right-hand side); and 
various follow-on actions, if necessary.
    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.

Changes to the Final Rule

    The FAA has revised the final rule to correctly designate the 
affected airplane models as ``Beech (Raytheon) Model BAe 125 series 
1000A and Model Hawker 1000 airplanes.''
    Additionally, a new ``Note 2'' has been added to the final rule to 
clarify that airworthiness authorities of countries in which Beech 
(Raytheon) Model BAe 125 series 800B and BAe 125 series 1000B airplanes 
are approved for operation should consider adopting corrective action 
that is similar to that required by this AD, since those airplanes are 
similar in design to the affected airplanes.

Conclusion

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

Cost Impact

    The FAA estimates that 25 airplanes of U.S. registry will be 
affected by this AD, that it will take approximately 1 work hour per 
airplane to accomplish the required actions, 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 $1,500, or $60 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:

96-11-17 Beech Aircraft Corporation (Formerly DeHavilland; Hawker 
Siddeley; British Aerospace, PLC; Raytheon Corporate Jets, Inc.): 
Amendment 39-9641. Docket 95-NM-180-AD.

    Applicability: Model BAe 125 series 1000A and Model Hawker 1000 
airplanes, as listed in Hawker Service Bulletin SB.27-168, dated 
July 17, 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 
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 800B and 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 800B and 
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 restriction or loss of the flight controls due to 
insufficient clearance and resultant chafing and damage to the flaps 
cable and/or turnbuckle and the airbrakes cable, accomplish the 
following:
    (a) Within 6 months after the effective date of this AD: Perform 
a one-time detailed visual inspection for adequate working 
clearances and for damage of the flap, airbrakes, and other flight 
control cables and turnbuckles with the structure at keel subframe 
15A (left- and right-hand sides) specified in Hawker Service 
Bulletin SB.27-168, dated July 17, 1995. Perform the inspection in 
accordance with that service bulletin. The detailed visual 
inspection for working clearances shall be conducted for each 
affected flight control through its full range of travel.

[[Page 28033]]

    (1) If all clearances are within the limits specified in the 
service bulletin, and no damage is found: No further action is 
required by this AD.
    (2) If the clearance for the flaps controls is outside the 
limits specified in the service bulletin: Prior to further flight, 
accomplish Modification SB 27-168-253705B in accordance with the 
service bulletin.
    (3) If the clearance for the airbrakes controls is outside the 
limits specified in the service bulletin: Prior to further flight, 
repair in accordance with the service bulletin.
    (4) If any cable is found to be damaged, and the damage exceeds 
the limits defined in Chapter 20-10-31 of the Airplane Maintenance 
Manual: Prior to further flight, replace the damaged cable with a 
new cable in accordance with the service bulletin.
    (5) If any turnbuckle, keel subframe, or polythene strip is 
found to be damaged: Prior to further flight, repair in accordance 
with a method approved by the Manager, Standardization Branch, ANM-
113, FAA, Transport Airplane Directorate.
    (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. 
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 3: 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 actions shall be done in accordance with Hawker Service 
Bulletin SB.27-168, dated July 17, 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,
