DEPARTMENT OF TRANSPORTATION
Federal Aviation Administration
14 CFR Part 39
[Docket No. FAA-2004-19766; Directorate Identifier 2002-NM-161-AD;
Amendment 39-14057; AD 2005-08-05]
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 adopting a new airworthiness directive (AD) for all
BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. This
AD requires replacing the aileron trim chain with a new, improved
aileron trim chain, and modifying the installation of the aileron trim
chain. This AD is prompted by a report that the aileron trim cables
were connected incorrectly on a correctly installed aileron trim chain.
We are issuing this AD to prevent incorrect connection of the aileron
trim cables, which could result in failure of the aileron trim system
and consequent reduced controllability of the airplane.
DATES: This AD becomes effective May 23, 2005.
The incorporation by reference of a certain publication listed in
the AD is approved by the Director of the Federal Register as of May
23, 2005.
ADDRESSES: For service information identified in this AD, contact
British Aerospace Regional Aircraft American Support, 13850 Mclearen
Road, Herndon, Virginia 20171.
Docket: The AD docket contains the proposed AD, comments, and any
final disposition. You can examine the AD docket on the Internet at
http://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 U.S.
Department of Transportation, 400 Seventh Street SW., room PL-401,
Washington, DC. This docket number is FAA-2004-19766; the directorate
identifier for this docket is 2002-NM-161-AD.
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)
227-1175; fax (425) 227-1149.
SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with an AD for all BAE Systems (Operations) Limited (Jetstream) Model
4101 airplanes. That action, published in the Federal Register on
December 8, 2004 (69 FR 70938), proposed to require replacing the
aileron trim chain with a new, improved aileron trim chain, and
modifying the installation of the aileron trim chain.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments that have been
submitted on the proposed AD.
Support for the Proposed AD
One commenter supports the proposed AD.
Request To Revise Compliance Time
One commenter, the airplane manufacturer, requests that we revise
the proposed AD to require installing modified aileron trim chains at
the next time the aileron trim circuit is broken down, but not later
than 30 months after the effective date of the AD. The proposed AD
requires compliance within 30 months after the effective date of the
AD. The commenter states that disassembly of the aileron trim circuit
introduces the risk of incorrect installation (cross-connection) during
re-assembly. This is the reason why British airworthiness directive
006-11-2001 requires compliance ``not later than the next aileron trim
circuit break down, or by 31 March 2005, whichever is the sooner.''
We do not concur with the commenter's request. In developing a
compliance time for this AD, we considered the urgency associated with
the subject unsafe condition, the manufacturer's recommendation, and
the practical aspect of accomplishing the required modification within
a period of time that corresponds to the normal scheduled maintenance
for most affected operators. As we explained in the proposed AD, a
compliance time of 30 months after the effective date of the AD is
comparable in length to the compliance time in the British
airworthiness directive, will allow the majority of operators
sufficient time to accomplish the proposed action during a regularly
scheduled maintenance visit, and will not compromise safety. We have
not changed this AD in this regard.
Conclusion
We have carefully reviewed the available data, including the
comments that have been submitted, and determined that air safety and
the public interest require adopting the AD as proposed.
Costs of Compliance
This AD will affect about 57 airplanes of U.S. registry. The
required actions will take about 36 work hours per airplane, at an
average labor rate of $65 per work hour. Required parts will cost about
$2,500 per airplane. Based on these figures, the estimated cost of the
AD for U.S. operators is $275,880, or $4,840 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
[[Page 20046]]
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.
