14 CFR Part 39
[Docket No. 94-CE-16-AD; Amendment 39-9123; AD 95-02-05]
Airworthiness Directives; Jetstream Aircraft Limited (Formerly
British Aerospace, Regional Airlines Limited) HP137 Mk1, Jetstream
Series 200, and Jetstream Models 3101 and 3201 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, Jetstream series
200, and Jetstream Models 3101 and 3201 airplanes. This action requires
repetitively inspecting the passenger/crew cabin door handle mounting
platform structure for cracks, and, if found cracked, replacing with a
structure of improved design as terminating action for the repetitive
inspections. The actions specified by this AD are intended to prevent
the inability to open the passenger/crew door because of a cracked
internal handle mounting platform structure, which, if not detected and
corrected, could result in passenger injury if emergency evacuation was
needed.
DATES: Effective March 17, 1995.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of March 17, 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;

Service, FAA, 1201 Walnut, suite 900, Kansas City, Missouri 64106;

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 certain JAL HP137 Mk1, Jetstream series 200, and Jetstream Models
3101 and 3201 airplanes was published in the Federal Register on
October 13, 1994 (59 FR 51879). The action proposed to require
repetitively inspecting the passenger/crew cabin door handle mounting
platform structure for cracks, and, if found cracked, replacing with a
structure of improved design as terminating action for the repetitive
inspections. The proposed actions would be accomplished in accordance
with Jetstream Service Bulletin 52-A-JA 930901, Revision 1, dated
February 11, 1994.
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, 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 nor add any additional burden upon the public than was
already proposed.
The FAA estimates that 165 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 $55 an hour. Based on these figures, the total
cost impact of the AD on U.S. operators is estimated to be $9,075. This
figure does not take into account any possible passenger/crew door
internal handle mounting platform structure replacements nor repetitive
inspections. The FAA has no way of determining how many of these
structures may have cracks or the number of repetitive inspections each
owner/operator may incur.
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 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 AD to read as follows:
95-02-05 Jetstream Aircraft Limited: Amendment 39-9123; Docket No.
94-CE-16-AD.
Applicability: HP137 Mk1, Jetstream Series 200, and Jetstream
Models 3101 and 3201 airplanes (all serial numbers), certificated in
any category. Compliance: Required upon the
[[Page 8295]] accumulation of 1,800 hours time-in-service (TIS) or
within the next 100 hours TIS after the effective date of this AD,
whichever occurs later, unless already accomplished, and thereafter
as indicated.
To prevent the inability to open the passenger/crew door because
of a cracked internal handle mounting platform structure, which, if
not detected and corrrected, could result in passenger injury if
emergency evacuation was needed, accomplish the following:
(a) Inspect the passenger/crew door internal handle mounting
platform structure for cracks in accordance with Part 1 of the
ACCOMPLISHMENT INSTRUCTIONS section of Jetstream Service Bulletin
(SB) 52-A-JA 930901, Revision 1, dated February 11, 1994 .
(1) If any cracked structure is found, prior to further flight,
replace the mounting platform structure with a new structure, part
number 137450C23, in accordance with Part 2 of the ACCOMPLISHMENT
INSTRUCTIONS section of Jetstream SB 52-A-JA 930901, Revision 1,
dated February 11, 1994.
(2) If no cracks are found, reinspect the mounting platform
structure at intervals not to exceed 1,800 hours TIS until a part
number 137450C23 mounting platform structure is installed.
(b) The repetitive inspections required by this AD may be
terminated upon installing a part number 137450C23 passenger/crew
door internal handle mounting platform structure. This installation
may be accomplished regardless of whether the existing structure is
cracked.
(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 should be forwarded
through an appropriate FAA Maintenance Inspector, who may add
comments and then send it to the Manager, Brussels ACO.
Note: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Brussels ACO.
(e) The inspection and modification (if necessary) required by
this AD shall be done in accordance with Jetstream Service Bulletin
52-A-JA 930901, Revision 1, dated February 11, 1994 . 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, Ayrshire, KA9 2RW Scotland;
telephone (44-292) 79888; or Jetstream Aircraft Inc., Librarian,
P.O. Box 16029, Dulles International Airport, Washington, DC, 20041-
6029. Copies may be inspected at the FAA, Central Region, Office of
the Assistant Chief Counsel, Room 1558, 601 E. 12th Street, Kansas
City, Missouri, or at the Office of the Federal Register, 800 North
Capitol Street, NW., suite 700, Washington, DC.
(f) This amendment (39-9123) becomes effective on March 17,
1995.
Issued in Kansas City, Missouri, on January 18, 1995.
