DEPARTMENT OF TRANSPORTATION
14 CFR Part 39
[Docket No. 94-NM-40-AD; Amendment 39-9045; AD 94-21-03]
Airworthiness Directives; Jetstream Model 4101 Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain Jetstream Model 4101 airplanes, that requires
installation of a placard near the decouple control handle for the
elevator control system to ensure that the pilots are made aware that
maintenance action is required to reset the disconnect unit once the
decouple control handle has been pulled. This amendment is prompted by
a report that, if the decouple control handle for the elevator control
system is pulled, the lock linkage will remain unlocked until it is
reset during maintenance. The actions specified by this AD are intended
to prevent reduced controllability of the airplane due to loss of the
mechanical linkage between the pilots' elevator controls, and each
pilot having control authority over only one-half of the elevator
control system.
DATES: Effective November 25, 1994. -
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of November 25, 1994.
ADDRESSES: The service information referenced in this AD may be
obtained from Jetstream Aircraft, Inc., P.O. Box 16029, Dulles
International Airport, Washington, DC 20041-6029. 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: William Schroeder, 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 Jetstream Model 4101
airplanes was published in the Federal Register on May 18, 1994 (59 FR
25843). That action proposed to require installation of a placard on
the left forward trim panel of the center console in line with the
decouple control handle of the elevator to ensure that the pilots are
made aware that maintenance action is required to reset the disconnect
unit once the decouple control handle has been pulled.-
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the single comment received.-
The commenter supports the proposed rule.-
After careful review of the available data, including the comment
noted above, the FAA has determined that air safety and the public
interest require the adoption of the rule as proposed.-
The FAA estimates that 8 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 $55 per work hour. Based on these figures, the total cost
impact of the AD on U.S. operators is estimated to be $440, or $55 per
airplane.
-The total 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.
-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

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.
