14 CFR Part 39
[Docket No. 2002-NM-90-AD; Amendment 39-13785; AD 2004-18-07]
RIN 2120-AA64
Airworthiness Directives; BAE Systems (Operations) Limited Model
BAe 146 and Avro 146-RJ Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment supersedes an existing airworthiness directive
(AD), applicable to certain BAE Systems (Operations) Limited Model BAe
146 and Avro 146-RJ series airplanes, that currently requires
identifying the part numbers of discharge valves and cabin pressure
controllers, and related investigative and corrective actions if
necessary. This amendment requires identifying the part number of an
additional cabin pressure controller, and related investigative and
corrective actions if necessary. The actions specified by this AD are
intended to prevent the installation of incorrect pressurization
discharge valves and cabin pressure controllers, which could subject
the airframe to excess stress and adversely affect the airframe fatigue
life. This action is intended to address the identified unsafe
condition.
DATES: Effective October 13, 2004.
The incorporation by reference of a certain publication listed in
the regulations is approved by the Director of the Federal Register as
of October 13, 2004.
The incorporation by reference of a certain other publication
listed in the regulations was approved previously by the Director of
the Federal Register as of September 10, 2001 (66 FR 40864, August 6,
2001).
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 National Archives and Records Administration
(NARA). For information on the availability of this material at NARA,

International Branch, ANM-116, FAA, Transport Airplane Directorate,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) by superseding AD 2001-15-23,
amendment 39-12358 (66 FR 40864, August 6, 2001), which is applicable
to certain BAE Systems (Operations) Limited Model BAe 146 and Avro 146-
RJ series airplanes, was published in the Federal Register on June 21,
2004 (69 FR 34312). The action proposed to continue to require
identifying the part numbers of discharge valves and cabin pressure
controllers, and related investigative and corrective actions if
necessary. The action also proposed to require identifying the part
number of an additional cabin pressure controller, and related
investigative and corrective actions 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.
Explanation of Change Made to Final Rule
We inadvertently omitted a paragraph identifier in the proposed AD.
We have revised this final rule to identify that paragraph as paragraph
(d) of this AD, and have reidentified subsequent paragraphs
accordingly.
Cost Impact
There are approximately 20 airplanes of U.S. registry that will be
affected by this AD.
The actions that are currently required by AD 2001-15-23 and
continued in this AD take approximately 3 work hours per airplane to
accomplish, at an average labor rate of $65 per work hour. Based on
these figures, the cost impact of the currently required actions on
U.S. operators is estimated to be $3,900, or $195 per airplane.
The new actions that are required in this AD will take
approximately 3 work hours to accomplish, at an average labor rate of
$65 per work hour. Based on these figures, the cost impact of the new
requirements on U.S. operators is estimated to be $3,900, or $195 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.
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
