Amendment 39-14280; AD 2005-19-15]
RIN 2120-AA64
Airworthiness Directives; BAE Systems (Operations) Limited
(Jetstream) Model 4101 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD), which applies to all BAE Systems (Operations) Limited (Jetstream)
Model 4101 airplanes. That AD currently requires operators to determine
the number of 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. The
existing AD also requires operators to revise the Airworthiness
Limitations section (ALS) of the Instructions for Continued
Airworthiness in the aircraft maintenance manual to reflect the new
life limits. This new AD requires revising the ALS to incorporate
extended and more restrictive life limits for structurally significant
items. This AD is prompted by engineering analysis of fleet operations
which resulted in more restrictive life limits. We are issuing this AD
to prevent failure of certain structurally significant items, including
the MLG and the NLG, which could result in reduced structural integrity
of the airplane.
DATES: This AD becomes effective October 26, 2005.
[[Page 55231]]
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of October 26,
2005.
On August 3, 2004 (69 FR 38816, June 29, 2004), the Director of the
Federal Register approved the incorporation by reference of BAE Systems
(Operations) Limited Service Bulletin J41-05-001, Revision 2, dated
March 15, 2002; BAE Systems (Operations) Limited Service Bulletin J41-
05-001, Revision 3, dated January 9, 2004; and BAE Systems (Operations)
Limited Service Bulletin J41-32-078, dated April 12, 2002.

227-2125; fax (425) 227-1149.
SUPPLEMENTARY INFORMATION: The FAA proposed to amend part 39 of the
Federal Aviation Regulations (14 CFR part 39) with an AD to supersede
AD 2004-13-07, amendment 39-13689 (69 FR 38816, June 29, 2004). The
existing AD applies to all BAE Systems (Operations) Limited (Jetstream)
Model 4101 airplanes. The proposed AD was published in the Federal
Register on May 2, 2005 (70 FR 22615), to continue to require operators
to determine the number of flight cycles accumulated on each component
of the main landing gear (MLG) and nose landing gear (NLG), 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 (ALS) of the Instructions for
Continued Airworthiness in the airplane maintenance manual (AMM) to
incorporate extended and more restrictive life limits for structurally
significant items.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comment that has been
submitted on the proposed AD. The commenter supports the proposed AD.
Explanation of Change to Applicability
We have revised the applicability of the proposed AD to identify
model designations as published in the most recent type certificate
data sheet for the affected models.
Explanation of Editorial Changes
We have corrected the date of Revision 3 of BAE Systems
(Operations) Limited Service Bulletin J41-05-001 in paragraph (f) of
this AD, and the British airworthiness directive reference in paragraph
(n) of this AD.
Conclusion
We have carefully reviewed the available data, including the
comment that has been received, and determined that air safety and the
public interest require adopting the AD with the changes described
previously. We have determined that these changes will neither increase
the economic burden on any operator nor increase the scope of the AD.
Costs of Compliance
This AD will affect about 57 airplanes of U.S. registry.
For the actions that are required by AD 2004-13-07, and retained in
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
AMM. The average labor rate is $65 per work hour. Based on these
figures, the estimated cost of the currently required actions for U.S.
operators is $7,410, or $130 per airplane.
The new revision of the AMM will take about 1 work hour per
airplane, at an average labor rate of $65 per work hour. Based on these
figures, the estimated cost of the new AMM revision specified in this
AD for U.S. operators is $3,705, or $65 per airplane.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
subtitle VII, part A, subpart III, section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We have determined that this AD will not have federalism
implications under Executive Order 13132. This AD 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.
For the reasons discussed above, I certify that this AD:
(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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD. See the ADDRESSES section for a location to
examine the regulatory evaluation.

directive (AD):
[[Page 55232]]
2005-19-15 BAE Systems (Operations) Limited (Formerly British
Aerospace Regional Aircraft): Amendment 39-14280. Docket No. FAA-
2005-21087; Directorate Identifier 2005-NM-019-AD.
Effective Date
(a) This AD becomes effective October 26, 2005.
Affected ADs
(b) This AD supersedes AD 2004-13-07.
Applicability
(c) This AD applies to all BAE Systems (Operations) Limited
Model Jetstream 4101 airplanes, certificated in any category.
Note 1: This AD requires revisions to certain operator
maintenance documents to include new inspections. Compliance with
these inspections is required by 14 CFR 91.403(c). For airplanes
that have been previously modified, altered, or repaired in the
areas addressed by these inspections, the operator may not be able
to accomplish the inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must
request approval for an alternative method of compliance according
to paragraph (m) of this AD. The request should include a
description of changes to the required inspections that will ensure
the continued damage tolerance of the affected structure. The FAA
has provided guidance for this determination in Advisory Circular
(AC) 25-1529.
Unsafe Condition
(d) This AD was prompted by engineering analysis of fleet
operations which resulted in more restrictive life limits. We are
issuing this AD to prevent failure of certain structurally
significant items, including the main landing gear and the nose
landing gear, which could result in reduced structural integrity of
the airplane.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Restatement of Requirements of AD 2004-13-07
