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 modifying the wiring of the starter-generator terminal
block. This AD results from a report of total electrical failure just
as the airplane landed. We are issuing this AD to prevent total
electrical failure and consequent reduced controllability of the
airplane.
DATES: This AD becomes effective January 17, 2006.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of January 17,
2006.
ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov or in person at the Docket Management Facility, U.S.
Department of Transportation, 400 Seventh Street, SW., Nassif Building,
room PL-401, Washington, DC.

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 September 6, 2005 (70 FR 52947).
That NPRM proposed to require modifying the wiring of the starter-
generator terminal block.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Support for the NPRM and Request for Further Information About
Alternative Methods of Compliance (AMOCs)
One commenter concurs with our decision to act on the
manufacturer's proposed solution to the unsafe condition. The commenter
also requests information about what kinds of AMOCs we will find
acceptable for compliance with the actions required by the final rule.
It is difficult to describe the specific types of AMOCs that we
will find acceptable for compliance with this AD because AMOCs vary
according to the airplane operator, and cannot be predicted until we
receive a written request. In general, AMOCs are different approaches
or techniques that are not specified in an AD that can, after our
approval, be used to correct an unsafe condition on an aircraft or
aircraft product. The AMOC must be acceptable to accomplish the intent
of the AD, provide an acceptable level of safety, and have sufficient
technical justification so that we can evaluate the request. For
example, a compliance time that differs from the requirements of the AD
can be approved if the revised time period in combination with other
mitigating actions provides an acceptable level of safety for the
requirements of the AD. The purpose of AMOCs is to ensure the most
efficient method of compliance for individual operators and also to
eliminate the need for constant AD revisions when acceptable methods
are developed for AD compliance.
It is not necessary to change the final rule in this regard.
Clarification of AMOC Paragraph
We have revised this action to clarify the appropriate procedure
for notifying the principal inspector before using any approved AMOC on
any airplane to which the AMOC applies.
Conclusion
We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD with the change described previously.
We have determined that this change will neither increase the economic
burden on any operator nor increase the scope of the AD.
Costs of Compliance
This AD affects about 57 airplanes of U.S. registry. The actions
take about 10 work hours per airplane, at an average labor rate of $65
per work hour. Based on these figures, the estimated cost of this AD
for U.S. operators is $37,050, or $650 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 and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
