[Docket No. 95-CE-12-AD; Amendment 39-9318; AD 95-15-12]
Airworthiness Directives; Jetstream Aircraft Limited (JAL) HP137
Mk1 and Jetstream Series 200 Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) that
applies to Jetstream Aircraft Limited (JAL) HP137 Mk1 and Jetstream
series 200 airplanes. This action requires incorporating operating
limitations that revise the maximum flap operating speed for DOWN flaps
to 120 knots indicated airspeed (KIAS), and prohibit extending the
flaps beyond the take-off position if ice is visible on the airplane.
An incident where an airplane of similar type design to the affected
airplanes experienced sudden pitch down because of the accumulation of
over one inch of ice prompted the proposed action. The actions
specified by this AD are intended to prevent sudden pitch down of the
airplane during icing conditions, which could lead to loss of control
of the airplane.
DATES: Effective September 19, 1995.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of September 19, 1995.
ADDRESSES: Service information that applies to this AD may be obtained
from Jetstream Aircraft Limited, Manager, Product Support, Prestwick
Airport, Ayrshire, KA9 2RW Scotland; telephone (44-292) 79888;

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an AD that would apply
to JAL HP137 Mk1, and Jetstream series 200 airplanes was published in
the Federal Register on March 2, 1995 (60 FR 11635). The action
proposed to incorporate operating limitations that revise the maximum
flap operating speed for DOWN flaps to 120 KIAS, and prohibit extending
flaps beyond the take-off position if ice is visible on the airplane.
Accomplishment of the proposed action would be in accordance with
Jetstream Service Bulletin (SB) 27-A-JA 911044, dated January 31, 1992.
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were received on the
proposed rule or the FAA's determination of the cost to the public.
After careful review of all available information related to the
subject presented above, the FAA has determined that air safety and the
public interest require the adoption of the rule as proposed except for
minor editorial corrections. The FAA has determined that these minor
corrections will not change the meaning of the AD and will not add any
additional burden upon the public than was already proposed.
The FAA estimates that 10 airplanes in the U.S. registry will be
affected by this AD, that it will take approximately 1 workhour per
airplane to accomplish the required action, and that the average labor
rate is approximately $60 an hour. Parts (placards fabricated from
local resources) cost approximately $30 per airplane. Based on these
figures, the total cost impact of the AD on U.S. operators is estimated
to be $900. This figure is based upon the assumption that no affected
airplane owner/operator has accomplished the proposed inspection.
All 10 of the affected airplanes are HP137 Mk1 airplanes; there are
no Jetstream series 200 airplanes registered in the United States, but
they are type certificated for operation in the United States.
According to FAA records, none of these HP137 Mk1 airplanes are in
operation. Since there are no airplanes currently in operation, the
cost impact of the proposed AD would be narrowed to only those owners/
operators returning their airplane to operation.
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
[[Page 39628]]
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 copy of the final 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.

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. App. 1354(a), 1421 and 1423; 49 U.S.C.
106(g); and 14 CFR 11.89.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding a new airworthiness directive
to read as follows:
95-15-12 Jetstream Aircraft Limited: Amendment 39-9318; Docket No.
95-CE-12-AD.
Applicability: HP137 Mk1 and Jetstream Series 200 airplanes (all
serial numbers), 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 use the authority
provided in paragraph (d) of this AD to request approval from the
FAA. This approval may address either no action, if the current
configuration eliminates the unsafe condition, or different actions
necessary to address the unsafe condition described in this AD. Such
a request should include an assessment of the effect of the changed
configuration on the unsafe condition addressed by this AD. In no
case does the presence of any modification, alteration, or repair
remove any airplane from the applicability of this AD.
Compliance: Required within the next 100 hours time-in-service
after the effective date of this AD, unless already accomplished.
To prevent sudden pitch down of the airplane during icing
conditions, which could lead to loss of control of the airplane,
accomplish the following:
(a) Modify the operating limitations placards located on the
flight deck in accordance with the ACCOMPLISHMENT INSTRUCTIONS
section of Jetstream Service Bulletin (SB) No. 27-A-JA 911044, dated
January 31, 1992. This modification limits the maximum flap
operating speed for DOWN flaps to 120 knots indicated airspeed
(KIAS). Insert a copy of this AD into the Limitations section of the
applicable airplane flight manual (AFM).
(b) Fabricate a placard with the words ``Do not extend the flaps
beyond the take-off position if ice is visible on the aircraft.
Ensure the landing gear selector is down prior to landing.'' Install
this placard on the airplane's instrument panel within the pilot's
clear view. Insert a copy of paragraph ``B.Instructions for Aircraft
Operations'' of the ACCOMPLISHMENT INSTRUCTIONS section of Jetstream
SB 27-A-JA 911044, dated January 31, 1992, into the Limitations
section of the AFM.
Note 2: Parts of the airplane where ice could specifically be
visible include the windshield wipers, center windshield, propeller
spinners, or inboard wing leading edges.
(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) An alternative method of compliance or adjustment of the
compliance time that provides an equivalent level of safety, may be
approved by the Manager, Brussels Aircraft Certification Office
(ACO), Europe, Africa, Middle East office, FAA, c/o American
Embassy, B-1000 Brussels, Belgium. The request shall be forwarded
through an appropriate FAA Maintenance Inspector, who may add
comments and then send it to the Manager, Brussels ACO.
Note 3: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Brussels Aircraft Certification Office.
(e) The inspections required by this AD shall be done in
accordance with Jetstream Service Bulletin No. 27-A-JA 911044, dated
January 31, 1992. 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 Jetstream
Aircraft Limited, Manager, Product Support, Prestwick Airport,
