Airworthiness Directives; Beech (Raytheon) Model BAe 125 Series
1000A and Model Hawker 1000 Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: This document proposes the adoption of a new airworthiness
directive (AD) that is applicable to certain Beech (Raytheon) Model BAe
125 series 1000A and Model Hawker 1000 airplanes. This proposal would
require a one-time inspection for correct sleeve lengths, an inspection
to detect discrepancies of the elevator pulley assembly, and correction
of any discrepancy. This proposal is prompted by reports indicating
that some aircraft have been fitted with an elevator pulley that was
assembled incorrectly during manufacture. The actions specified by the
proposed AD are intended to prevent reduced structural integrity of the
elevator control circuit due to failure of one or more outer lugs or
malfunction of the elevator pulley assembly as a result of incorrect
assembly of the pulley.
DATES: Comments must be received by July 8, 1996.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Transport Airplane Directorate, ANM-103,

Discussion
The Civil Aviation Authority (CAA), which is the airworthiness
authority for the United Kingdom, recently notified
[[Page 27029]]
the FAA that an unsafe condition may exist on certain Beech (Raytheon)
Model BAe 125 series 1000A and Model Hawker 1000 airplanes. The CAA
advises that it has received reports indicating that some aircraft have
been fitted with an elevator pulley that was assembled incorrectly
during manufacture. Failure of one or more outer lugs or malfunction of
the elevator pulley assembly, if not corrected, could result in reduced
structural integrity of the elevator control circuit.
Explanation of Relevant Service Information
The manufacturer has issued Hawker Service Bulletin SB 27-161,
Revision 1, dated July 29, 1994, which describes procedures for a one-
time inspection for correct sleeve lengths, and a one-time visual
inspection to detect discrepancies of the elevator pulley assembly. The
CAA classified this service bulletin as mandatory in order to assure
the continued airworthiness of these airplanes in the United Kingdom.
FAA's Conclusions
These airplane models are manufactured in the United Kingdom and
are type certificated for operation in the United States under the
provisions of section 21.29 of the Federal Aviation Regulations (14 CFR
21.29) and the applicable bilateral airworthiness agreement. Pursuant
to this bilateral airworthiness agreement, the CAA has kept the FAA
informed of the situation described above. The FAA has examined the
findings of the CAA, reviewed all available information, and determined
that AD action is necessary for products of this type design that are
certificated for operation in the United States.
Explanation of Requirements of Proposed Rule
Since an unsafe condition has been identified that is likely to
exist or develop on other airplanes of the same type design, the
proposed AD would require a one-time inspection for correct sleeve
lengths, a one-time visual inspection to detect discrepancies of the
elevator pulley assembly, and correction of any discrepancy. The
inspections would be required to be accomplished in accordance with the
service bulletin described previously. Correction of discrepancies
would be required to be accomplished in accordance with a method
approved by the FAA.
Cost Impact
The FAA estimates that 40 airplanes of U.S. registry would be
affected by this proposed AD, that it would take approximately 1 work
hour per airplane to accomplish the proposed actions, and that the
average labor rate is $60 per work hour. Based on these figures, the
cost impact of the proposed AD on U.S. operators is estimated to be
$2,400, or $60 per airplane.
The cost impact figure discussed above is based on assumptions
that no operator has yet accomplished any of the proposed 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 proposed herein would 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
proposal would not have sufficient federalism implications to warrant
the preparation of a Federalism Assessment.
For the reasons discussed above, I certify that this proposed
regulation (1) is not a ``significant regulatory action'' under
Executive Order 12866; (2) is not a ``significant rule'' under the DOT
Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);
and (3) if promulgated, 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 copy of the draft
regulatory evaluation prepared for this action is contained in the
Rules Docket. A copy of it may be obtained by contacting the Rules
Docket at the location provided under the caption ADDRESSES.

The Proposed Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration proposes to amend
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:
Beech Aircraft Company (Formerly DeHavilland; Hawker Siddeley;
British Aerospace, PLC; Raytheon Corporate Jets, Inc.): Docket 95-
NM-166-AD.
Applicability: Model BAe 125 series 1000A and Model Hawker 1000
airplanes; as listed in Hawker Service Bulletin SB 27-161, Revision
1, dated July 29, 1994; 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 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 Model BAe 125 series 1000B 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 reduced structural integrity of the elevator control
circuit, accomplish the following:
(a) Within 6 months after the effective date of this AD: Perform
a one-time inspection for correct sleeve lengths, and a one-time
visual inspection to detect discrepancies of the elevator pulley
assembly, in accordance with Hawker Service Bulletin SB 27-161,
Revision 1, dated July 29, 1994.
(1) If no discrepancy is found, no further action is required by
this AD.
(2) If any discrepancy is found, prior to further flight,
correct the discrepancy 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,
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.
[[Page 27030]]
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.
Issued in Renton, Washington, on May 22, 1996.
John J. Hickey,
Acting Manager, Transport Airplane Directorate, Aircraft Certification
Service.
