Airworthiness Directives; BAE Systems (Operations) Limited
(Jetstream) Model 4101 Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to all BAE Systems (Operations) Limited (Jetstream) Model
4101 airplanes. This AD requires operators to determine the flight
cycles accumulated on each component of the main landing gear (MLG) and
the nose landing gear (NLG), and to replace each component that reaches
its life limit with a serviceable component. This AD also requires
operators to revise the Airworthiness Limitations section of the
Instructions for Continued Airworthiness in the aircraft maintenance
manual to reflect the new life limits. This action is necessary to
prevent failure of certain components of the MLG and the NLG, which
could result in failure of either or both landing gears, and consequent
damage to the airplane and injury to passengers or crewmembers. This
action is intended to address the identified unsafe condition.
DATES: Effective August 3, 2004.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of August 3, 2004.
ADDRESSES: The service information referenced in this AD may be
obtained from British Aerospace Regional Aircraft American Support,
13850 Mclearen Road, Herndon, Virginia 20171. 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 National Archives and Records Administration
(NARA). For information on the availability of this material at NARA,

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 all BAE Systems (Operations)
Limited (Jetstream) Model 4101 airplanes was published in the Federal
Register on March 5, 2004 (69 FR 10385). That action proposed to
require operators to determine the flight cycles accumulated on each
component of the main landing gear and the nose landing gear, and to
replace each component that reaches its life limit with a serviceable
component. That action also proposed to require operators to revise the
Airworthiness Limitations section of the Instructions for Continued
Airworthiness to reflect the new life limits.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were submitted in response
to the proposal or the FAA's determination of the cost to the public.
Conclusion
We have determined that air safety and the public interest require
the adoption of the rule as proposed.
Explanation of Change Made to the Proposed Rule
We have revised paragraph (a) the final rule to include BAE Systems
(Operations) Limited Service Bulletin J41-05-001, Revision 3, dated
January 9, 2004, as an additional appropriate source of service
information for calculating the total accumulated flight cycles. In
addition, we have revised paragraph (f) of the final rule to give
operators credit for accomplishing the same calculation per two earlier
revisions of Service Bulletin J41-05-001: Revision 1, dated April 10,
2001, Revision 2, dated March 15, 2002.
Cost Impact
We estimate that 57 airplanes of U.S. registry will be affected by
this AD. It will take approximately 1 work hour per airplane to
accomplish the required determination of the number of flight cycles,
and 1 work hour per airplane to accomplish the required revision of the
aircraft maintenance manual. The average labor rate is $65 per work
hour. Based on these figures, the cost impact of the AD on U.S.
operators is estimated to be $7,410, or $130 per airplane.
[[Page 38817]]
The 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 cost impact figures discussed
in AD rulemaking actions represent only the time necessary to perform
the specific actions actually required by the AD. These figures
typically do not include incidental costs, such as the time required to
gain access and close up, planning time, or time necessitated by other
administrative actions.
Regulatory Impact
The regulations adopted herein will not have a substantial direct
effect 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, it
is determined that this final rule does not have federalism
implications under Executive Order 13132.
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
