[Docket No. FAA-2005-21137; Directorate Identifier 2002-NM-86-AD;
Amendment 39-14200; AD 2005-15-11]

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 adopting a new airworthiness directive (AD) for all
BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. This
AD requires repetitive detailed and specialized inspections to detect
fatigue damage in the fuselage, replacement of certain bolt assemblies,
and corrective actions if necessary. This AD results from a review of
primary airframe fatigue test results and a Maintenance Steering Group
3 (MSG-3) analysis. We are issuing this AD to detect and correct
fatigue damage of the fuselage, door, engine nacelle, empennage, and
wing structures, which could result in reduced structural integrity of
the airplane.
DATES: Effective August 30, 2005.
The Director of the Federal Register approved the incorporation by
reference
[[Page 43026]]
of a certain publication listed in the AD as of August 30, 2005.
ADDRESSES: You may examine the AD docket on the Internet at http://www.dms.dot.gov

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the AD docket on the Internet at http://www.dms.dot.gov
or in person at the Docket Management Facility office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the
street address stated in the ADDRESSES section.
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to all BAE Systems
(Operations) Limited (Jetstream) Model 4101 airplanes. That NPRM was
published in the Federal Register on May 9, 2005 (70 FR 24326). That
NPRM proposed to require repetitive detailed and specialized
inspections to detect fatigue damage in the fuselage, replacement of
certain bolt assemblies, and corrective actions if necessary.
Comments
We provided the public the opportunity to participate in the
development of this AD. We received no comments on the NPRM or on the
determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.
Costs of Compliance
The following table provides the estimated costs for U.S. operators
to comply with this AD.
Estimated Costs
--------------------------------------------------------------------------------------------------------------------------------------------------------
Cost per Number of
Average airplane, per U.S.-
Action Work hours labor rate Parts inspection registered Fleet cost
per hour cycle airplanes
--------------------------------------------------------------------------------------------------------------------------------------------------------
Inspections of the door structure...... 17 $65 None...................... $1,105 57 Up to $62,985, per inspection
cycle.
Inspections of the fuselage structure.. 164 65 None...................... 10,660 57 Up to $607,620, per inspection/
replacement cycle.
Inspections of the engine nacelle 4 65 None...................... 260 57 Up to $14,820, per inspection
structure. cycle.
Inspections of the empennage structure. 14 65 None...................... 910 57 Up to $51,870, per inspection
cycle.
Inspections of the wing structure...... 24 65 None...................... 1,560 57 Up to $88,920, per inspection
cycle.
--------------------------------------------------------------------------------------------------------------------------------------------------------
In summary, required actions will take about 223 work hours per
airplane, at an average labor rate of $65 per work hour. Based on these
figures, the estimated cost of the AD for U.S. operators is up to
$826,215, or $14,495 per airplane, per inspection cycle.
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 and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.

Service Bulletin Reference
(f) The term ``the service bulletin,'' as used in this AD, means
BAE Systems (Operations) Limited Service Bulletin J41-51-001,
Revision 2, dated April 30, 2003.
Inspection and Corrective Actions
(g) At the compliance times specified in the ``Initial
Compliance Time'' column of Tables 1, 2, 3, 4, and 5 of this AD: Do
the applicable detailed inspections and specialized inspections to
detect fatigue damage, and replacement of certain bolt assemblies,
and any applicable corrective actions, in accordance with the
Accomplishment Instructions of the service bulletin. Do any
corrective action before further flight. Repeat the inspections and
replacement thereafter at intervals specified in the ``Repetitive
Intervals'' column of Tables 1, 2, 3, 4, and 5 of this AD.
Note 1: For the purposes of this AD, a detailed inspection is:
``An intensive examination of a specific item, installation, or
assembly to detect damage, failure, or irregularity. Available
lighting is normally supplemented with a direct source of good
lighting at an intensity deemed appropriate. Inspection aids such as
mirrors, magnifying lenses, etc. may be necessary. Surface cleaning
and elaborate procedures may be required.''

paragraphs (g) and (h) of this AD.
No Report Required
(j) Although the service bulletin referenced in this AD
specifies to submit certain information to the manufacturer, this AD
does not include that requirement.
Alternative Methods of Compliance (AMOCs)
(k) The Manager, International Branch, ANM-116, Transport
