[Docket No. 94-CE-14-AD; Amendment 39-9119; AD 95-01-08]
Airworthiness Directives; Jetstream Aircraft Limited (Formerly
British Aerospace, Regional Airlines Limited) HP137 Mk1 and Jetstream
Series 200 Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment supersedes AD 81-09-03 R1, which currently
requires repetitively inspecting the rudder pedal adjusting mounting
bracket for cracks on Jetstream Aircraft Limited (JAL) HP137 Mk1 and
Jetstream Series 200 airplanes, and replacing any cracked bracket. The
Federal Aviation Administration's policy on aging commuter-class
aircraft is to eliminate, or in certain instances, reduce the number of
repetitions of certain short-interval inspections when improved parts
or modifications are available. This action requires replacing the
mounting bracket with a new mounting bracket of improved design as
terminating action for the repetitive inspections that are currently
required by AD 81-09-03 R1. The actions specified by this AD are
intended to prevent inadvertent rudder movement caused by a cracked
rudder pedal adjusting bracket, which, if not detected and corrected,
could result in loss of rudder control.
[[Page 2494]] DATES: Effective February 20, 1995.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of February 20, 1995.

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 and Jetstream 200 series airplanes was
published in the Federal Register on October 13, 1994 (59 FR 51877).
The action proposed superseding AD 81-09-03 R1 with a new AD that would
(1) retain the inspections of the rudder pedal adjusting mounting
bracket for cracks and require replacing any cracked part as required
by the current AD; and (2) require replacing this mounting bracket with
an improved part of increased sectional dimension, P/N 1379111E 1, as
terminating action for the repetitive inspections. The proposed
inspection would be accomplished in accordance with Jetstream Service
Bulletin No. 9/10, dated April 28, 1981. The proposed replacement would
be accomplished in accordance with the Instructions to Modification No.
5162, Part 1 and Part 2, Issue 1, dated June 1981.
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.
This action is based on the FAA's aging commuter-class aircraft
policy. This policy simply states that airplane owners/operators should
incorporate a known design change when it could eliminate, or, in
certain instances, reduce the number of critical repetitive
inspections.
The FAA estimates that 11 airplanes in the U.S. registry will be
affected by this AD, that it will take approximately 160 workhours per
airplane to accomplish the required action, and that the average labor
rate is approximately $55 an hour. Parts cost approximately $1,800 per
airplane. Based on these figures, the total cost impact of the AD on
U.S. operators is estimated to be $116,600.
All 11 of the affected airplanes are HP137 Mk1's; 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 or anywhere near operating condition. For this reason, JAL no
longer stocks Modification No. 5162, but can develop modification kits
within three months after order. Since there are no airplanes currently
in operation, the cost impact of this AD is 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
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 removing AD 81-09-03 R1, Amendment
39-4150, and by adding a new AD to read as follows:
95-01-08 Jetstream Aircraft Limited: Amendment 39-9119; Docket No.
94-CE-14-AD. Supersedes AD 81-09-03 R1, Amendment 39-4150.
Applicability: HP137 Mk1 and Jetstream Series 200 airplanes (all
serial numbers), certificated in any category.
Compliance: Required as indicated in the body of this AD, unless
already accomplished.
To prevent inadvertent rudder movement caused by a cracked
rudder pedal adjusting mounting bracket, which could result in loss
of rudder control, accomplish the following:
(a) Within the next 100 hours time-in-service (TIS) after the
effective date of this AD, unless already accomplished (compliance
with AD 81-09-03 R1), inspect the rudder pedal adjusting mounting
bracket for cracks in accordance with Jetstream Service Bulletin
(SB) No. 9/10, dated April 28, 1981.
(1) If cracks are found, prior to further flight, replace the
mounting bracket with an improved part of increased sectional
dimension, part number (P/N) 1379111E 1, in accordance with the
Instructions to Modification No. 5162, Part 1 and Part 2, Issue 1,
dated June 1981. This replacement is referenced as Modification No.
5162.
(2) If no cracks are found, reinspect at intervals not to exceed
100 hours TIS until Modification No. 5162 is incorporated.
(b) Upon the accumulation of 15,000 hours TIS or within the next
200 hours TIS after the effective date of this AD, whichever occurs
later, replace the rudder pedal adjusting mounting bracket with an
improved part of [[Page 2495]] increased sectional dimension, P/N
1379111E 1 (Modification No. 5162), in accordance with the
Instructions to Modification No. 5162, Part 1 and Part 2, Issue 1,
dated June 1981.
(c) Incorporating Modification 5162 as specified in paragraphs
(a)(1) and (b) of this AD eliminates the repetitive inspection
requirement of this AD.
(d) Special flight permits may be issued in accordance with
Secs. 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.
(e) An alternative method of compliance or adjustment of the
initial and repetitive compliance times 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.
(f) The inspection required by this AD shall be done in
accordance with Jetstream Service Bulletin No. 9/10, dated April 28,
1981. The replacement required by this AD shall be done in
accordance with Instructions to Modification No. 5162, Part 1 and
Part 2, Issue 1, dated June 1981. 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
