[Docket No. 97-NM-313-AD]
RIN 2120-AA64
Airworthiness Directives; Raytheon Model BAe 125-1000A and Hawker
1000 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Notice of proposed rulemaking (NPRM); proposed rescission.
-----------------------------------------------------------------------
SUMMARY: This document proposes to rescind an existing airworthiness
directive (AD), applicable to certain Raytheon Model BAe 125-1000A and
Hawker 1000 series airplanes, that currently requires inspections of
the thrust reverser system for integrity, and correction of any
discrepancy found. The actions specified by that AD are intended to
prevent a significant reduction in the controllability of the airplane
due to an in-flight deployment of a thrust reverser. Since the issuance
of that AD, the FAA has issued a separate AD that requires the
accomplishment of modifications that terminate the requirements of the
existing AD.
DATES: Comments must be received by October 12, 1999.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Transport Airplane Directorate, ANM-114,
Attention: Rules Docket No. 97-NM-313-AD, 1601 Lind Avenue, SW.,
Renton, Washington 98055-4056. Comments may be inspected at this
location between 9:00 a.m. and 3:00 p.m., Monday through Friday, except
Federal holidays.
Information pertaining to this proposed rule may be examined at the
FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton,
Washington.
FOR FURTHER INFORMATION CONTACT: Norman B. Martenson, Manager,
International Branch, ANM-116, FAA, Transport Airplane Directorate,
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425)

Interested persons are invited to participate in the making of the
proposed rule by submitting such written data, views, or arguments as
they may desire. Communications shall identify the Rules Docket number

communications received on or before the closing date for comments,
specified above, will be considered before taking action on the
proposed rule. The proposals contained in this notice may be changed in
light of the comments received.
Comments are specifically invited on the overall regulatory,
economic, environmental, and energy aspects of the proposed rule. All
comments submitted will be available, both before and after the closing
date for comments, in the Rules Docket for examination by interested
persons. A report summarizing each FAA-public contact concerned with
the substance of this proposal will be filed in the Rules Docket.

Discussion
On April 20, 1994, the FAA issued AD 94-09-11, amendment 39-8900
(59 FR 22125, April 29, 1994), applicable to certain Raytheon Model BAe
125-1000A and Hawker 1000 series airplanes, to require inspections of
the thrust reverser system for integrity, and correction of any
discrepancy found. That action was prompted by a report that there is a
possibility of failure of the drive links (or attachments) on the
thrust reversers of these airplanes due to the single link design
concept of the thrust reverser link and lock system. That condition, if
not corrected, could result in inadvertent deployment of a thrust
reverser during flight. The requirements of that AD are intended to
prevent a significant reduction in the controllability of the airplane
due to an in-flight deployment of a thrust reverser.
[[Page 49113]]
Actions Since Issuance of Previous Rule
Since the issuance of that AD, the FAA has issued AD 96-22-03,
amendment 39-9792 (61 FR 57295, November 6, 1996), which requires
modifications of the thrust reversers on certain Raytheon Model BAe
125-1000A and Model Hawker 1000 series airplanes. AD 96-22-03 became
effective on December 11, 1996, and the actions specified in that AD
were required to be accomplished within 6 months after that date.
FAA's Conclusions
Since the actions required by AD 96-22-03 were required to be
accomplished by June 11, 1997, and because such accomplishment
constitutes terminating action for the requirements of AD 94-09-11, the
FAA has determined that it is necessary to rescind AD 94-09-11 in order
to prevent operators from performing an unnecessary action.
This proposed action would rescind AD 94-09-11. Rescission of AD
94-09-11 would constitute only such action, and, if followed by a final
action, would not preclude the agency from issuing another notice in
the future, nor would it commit the agency to any course of action in
the future.
Cost Impact
The FAA estimates that 14 airplanes of U.S. registry are affected
by AD 94-09-11. The actions that are currently required by that AD take
approximately 3 work hours per airplane to accomplish, at an average
labor rate of $60 per work hour. Based on these figures, the cost
impact of the currently required actions on U.S. operators is estimated
to be $180 per airplane. However, the adoption of this proposed
rescission would eliminate those costs.
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
Dcket at the location provided under the caption ADDRESSES.
