14 CFR Part 39
[Docket No. 2002-NM-63-AD; Amendment 39-13543; AD 2004-06-17]
RIN 2120-AA64
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, that requires repetitive inspections for damage of the
horizontal and vertical stabilizer attachment fittings, and corrective
action if necessary. This action is necessary to detect and correct
damage of the horizontal and vertical stabilizer attachment fittings,
which could result in reduced structural integrity of the horizontal
and vertical stabilizers and consequent reduced controllability of the
airplane. This action is intended to address the identified unsafe
condition.
DATES: Effective May 4, 2004.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of May 4, 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 Office of the Federal Register, 800 North Capitol
Street, NW., suite 700, Washington, DC.
FOR FURTHER INFORMATION CONTACT: Todd Thompson, Aerospace Engineer,
International Branch, ANM-116, FAA, Transport Airplane Directorate,
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425)

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 November 18, 2003 (68 FR 65006). That action proposed to
require repetitive inspections for damage of the horizontal and
vertical stabilizer attachment fittings, and corrective action if
necessary.
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
The FAA has determined that air safety and the public interest
require the adoption of the rule as proposed.
Cost Impact
The FAA estimates that 57 airplanes of U.S. registry will be
affected by this AD, that it will take approximately 120 work hours per
airplane to accomplish the required actions, and that 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 $444,600, or $7,800 per
airplane.
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

AD.
Applicability: All Model Jetstream 4101 airplanes, certificated
in any category.
Compliance: Required as indicated, unless accomplished
previously.
To detect and correct damage of the horizontal and vertical
stabilizer attachment fittings, which could result in reduced
structural integrity of the horizontal and vertical stabilizers and
consequent reduced controllability of the airplane, accomplish the
following:
Service Bulletin References
(a) The following information pertains to the service bulletin
referenced in this AD:
(1) The term ``service bulletin'' as used in this AD means the
Accomplishment Instructions of BAE Systems (Operations) Limited
Service Bulletin J41-55-012, dated October 24, 2002.
(2) Although the service bulletin referenced in this AD
specifies to report all findings to the manufacturer by completing
the Reporting Data Form on Figures 1, 2, 3, and 4 of the service
bulletin, this AD does not include such a requirement.
(3) Inspections and corrective actions accomplished before the
effective date of this AD per BAE Systems (Operations) Limited
Service Bulletin J41-55-011, dated January 25, 2002, are acceptable

intervals not to exceed 8 years.
Note 1: For the purposes of this AD, a detailed inspection is
defined as: ``An intensive visual examination of a specific
structural area, system, installation, or assembly to detect damage,
failure, or irregularity. Available lighting is normally
supplemented with a direct source of good lighting at intensity
deemed appropriate by the inspector. Inspection aids such as mirror,
magnifying lenses, etc., may be used. Surface cleaning and elaborate
access procedures may be required.''
Repair
(c) If any damage (cracks, corrosion, wear, fretting) is found
during any inspection per paragraph (b) of this AD: Do the
applicable corrective action specified in the service bulletin at
the time specified in the service bulletin per the service bulletin,
except as required by paragraph (d) of this AD.
(d) If any damage is found that is outside the limits specified
