14 CFR Part 39
[Docket No. 2002-NM-172-AD; Amendment 39-14488; AD 2006-04-07]
RIN 2120-AA64
Airworthiness Directives; BAE Systems (Operations) Limited Model
BAe 146 and Avro 146-RJ Airplanes
AGENCY: Federal Aviation Administration, Department of Transportation
(DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to all BAE Systems (Operations) Limited Model BAe 146 and
Avro 146-RJ airplanes, that requires installation of a linear fluid-
filled damper between each elevator surface and the airplane structure
on both the left and right sides of the airplane, along with related
structural and system modifications. The actions specified by this AD
are intended to prevent pitch oscillation (vertical bouncing) of the
fuselage due to excessive ice buildup on the elevator servo tab, and
consequent reduced controllability of the airplane. This action is
intended to address the identified unsafe condition.
DATES: Effective March 24, 2006.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of March 24, 2006.
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 FAA, Transport Airplane Directorate, 1601 Lind Avenue,
SW., Renton, Washington.
FOR FURTHER INFORMATION CONTACT: Todd Thompson, Aerospace Engineer;
International Branch, ANM-116, Transport Airplane Directorate, FAA,
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425)
227-1175; fax (425) 227-1149.
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 Model BAe 146 and Avro 146-RJ airplanes was published as a
supplemental notice of proposed rulemaking (NPRM) in the Federal
Register on December 8, 2005 (70 FR 72942). That action proposed to
require installation of a linear fluid-filled damper between each
elevator surface and the airplane structure on both the left and right
sides of the airplane, along with related structural and system
modifications. That action also revised and updated applicable service
information and revised the compliance time to accurately reflect the
compliance time specified by the service information.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. We received no comments on the
supplemental 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,
except for certain minor editorial changes that have no effect on any
legal or technical aspect of the AD.
Cost Impact
The FAA estimates that 55 airplanes of U.S. registry will be
affected by this AD. Accomplishment of the required actions specified
in the referenced BAE Systems (Operations) Limited modification service
bulletins will require an approximate number of work hours as shown in
the following table, at an average labor rate of $65 per work hour.

\1\ (For Model BAE 146 airplanes only).
\2\ (For Model Avro 146-RJ airplanes only).
Based on these figures, the total cost impact of this AD on U.S.
operators is estimated to be between $1,079,980 and $1,108,580, or
between $19,636 and $20,156 per airplane.
The cost impact figures discussed above are 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.
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 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
