DEPARTMENT OF TRANSPORTATION
Federal Aviation Administration
14 CFR Part 39
[Docket No. 2003-NM-94-AD; Amendment 39-13664; AD 2004-12-05]
RIN 2120-AA64
Airworthiness Directives; BAE Systems (Operations) Limited Model
BAe 146 Series 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 Model BAe 146 series
airplanes, that requires repetitive detailed inspections of the inside
of each air conditioning sound-attenuating duct, and corrective actions
as necessary. This action is necessary to prevent impairment of the
operational skills and abilities of the flightcrew caused by the
inhalation of agents released from oil or oil breakdown products, which
could result in reduced controllability of the airplane. This action is
intended to address the identified unsafe condition.
DATES: Effective July 14, 2004.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of July 14, 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 National Archives and Records Administration
(NARA). For information on the availability of this material at NARA,

FOR FURTHER INFORMATION CONTACT: Todd Thompson, Aerospace Engineer,
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) to include an airworthiness
directive (AD) that is applicable to all BAE Systems (Operations)
Limited Model BAe 146 series airplanes published in the Federal
Register on April 15, 2004 (69 FR 19954). That action proposed to
require repetitive detailed inspections of the inside of each air
conditioning sound-attenuating duct, and corrective actions as
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
We have determined that air safety and the public interest require
the adoption of the rule as proposed.
Interim Action
This is considered to be interim action until final action is
identified, at which time the FAA may consider further rulemaking.
[[Page 32252]]
Cost Impact
We estimate that 20 airplanes of U.S. registry will be affected by
this AD, that it will take approximately 5 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 $6,500, or $325 per airplane, per
inspection cycle.
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

Adoption of the Amendment
0
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends part 39 of
the Federal Aviation Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. Section 39.13 is amended by adding the following new airworthiness
directive:
2004-12-05 BAE Systems (Operations) Limited (Formerly British
Aerospace Regional Aircraft): Amendment 39-13664. Docket 2003-NM-94-
AD.
Applicability: All Model BAe 146 series airplanes, certificated
in any category.
Compliance: Required as indicated, unless accomplished
previously.
To prevent impairment of the operational skills and abilities of
the flightcrew caused by the inhalation of agents released from oil
or oil breakdown products, which could result in reduced
controllability of the airplane, accomplish the following:
Repetitive Inspections and Corrective Action
(a) Within 120 days or 500 flight cycles after the effective
date of this AD, whichever is first: Do a detailed inspection of the
inside of each of the four air conditioning sound-attenuating ducts
for the presence of oil contamination, and corrective actions as
applicable. Do all of the applicable actions per BAE Systems
(Operations) Limited Inspection Service Bulletin ISB.21-156, dated
October 31, 2002. Any corrective action must be done before further
flight. Repeat the inspection thereafter at intervals not to exceed
4,000 flight cycles.
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.''
Submission of Information Not Required
(b) Although the service bulletin specifies to report inspection
results to the manufacturer, this AD does not include such a
requirement.
