ACTION: Final rule.
AGENCY:
The FAA is superseding an
existing airworthiness directive (AD),
which applies to certain BAE Systems
(Operations) Limited Model BAe 146
and Avro 146–RJ airplanes. That AD
currently requires one-time inspections
of the inner webs and flanges at frames
15, 18, 41, and 43 for evidence of
corrosion or cracking; and corrective
actions if necessary. This new AD
instead requires new repetitive
inspections and expands the area to be
inspected. This new AD also expands
the applicability and provides an

optional action that would extend the
repetitive inspection interval. This AD
results from a report indicating that in
some cases the inspections required by
the existing AD revealed no damage, yet
frame corrosion and cracking were later
found during scheduled maintenance in
the two forward fuselage frames 15 and
18. We are issuing this AD to prevent
reduced structural integrity of the
airplane.
DATES: This AD becomes effective July
17, 2006.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD
as of July 17, 2006.

Examining the Docket
You may examine the airworthiness
directive (AD) docket on the Internet at
https://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 street address stated in the
ADDRESSES section.
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that
supersedes AD 2004–01–07, amendment
39–13421 (69 FR 869, January 7, 2004).
The existing AD applies to certain BAE
Systems (Operations) Limited Model
BAe 146 and Avro 146-RJ airplanes.
That NPRM was published in the
Federal Register on December 13, 2005
(70 FR 73665). That NPRM proposed to
continue to require inspections of
certain inner webs and flanges for signs
of corrosion (including cracks,
PO 00000
Frm 00008
Fmt 4700
Sfmt 4700
blistering, or flaking paint), and
corrective action if necessary. That
NPRM also proposed to add repetitive
inspections, expand the area to be
inspected, expand the applicability, and
provide an optional action that would
extend the proposed repetitive
inspection interval.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comment that has been
received on the NPRM.
Request To Require Revised Service
Information
Air Wisconsin requests that we delay
issuing the final rule until the
manufacturer revises Inspection Service
Bulletin (ISB) ISB.53–182, dated March
16, 2005 (cited in the NPRM). The
commenter reports that BAE plans to
revise the ISB to extend the inspection
area after recent inspection data
revealed evidence of corrosion cracking
on some frame outer flanges. The
commenter states that delaying issuance
of the final rule would allow time to
determine whether the revised ISB
better addresses the identified unsafe
condition. The commenter adds that it
just makes more sense in regards to cost
effectiveness and airworthiness safety
for operators to perform the most
thorough and up-to-date inspection on
their airplanes.
We acknowledge the commenter’s
concern, but we do not agree to delay
the issuance of the final rule. Release of
a revised service bulletin is not
imminent. To delay this action would
be inappropriate because we have
determined that an unsafe condition
exists. However, we may consider
further rulemaking in the future to
expand the inspection area if warranted.
In light of the identified unsafe
condition, however, we consider it
appropriate to proceed with this final
rule as proposed.
Conclusion
We have carefully reviewed the
available data, including the comment
that has been submitted, and
determined that air safety and the
public interest require adopting the AD
as proposed.

Adoption of the Amendment
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.

Parts cost
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.

a report indicating that certain oxygen
cylinder supports may not have been
properly heat-treated. We are issuing
this AD to prevent failure of the oxygen
cylinder support under the most critical
flight load conditions, which could
cause the oxygen cylinder to come loose
and leak oxygen. Leakage of oxygen
could result in oxygen being unavailable
for the flightcrew or could result in a
fire hazard in the vicinity of the leakage.

Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments received.
Request To Revise Estimated Costs of
Compliance
Boeing requests that we revise the
estimated Costs of Compliance stated in
the NPRM to include the work hours
needed for replacing any support
bracket of the crew oxygen cylinder
having a manufacturing date that is
within a certain range, and for testing
following such replacement. Boeing
notes that the NPRM included the
estimated cost of the inspection only.
We do not agree. The economic
analysis of an AD is limited to the cost
of actions that are actually required. The
economic analysis does not consider the
costs of conditional actions, such as
corrective actions (e.g., replacing a
support having an affected
manufacturing date with a new
support). Such conditional action would
be required—regardless of AD
direction—to correct an unsafe
condition identified in an airplane and
to ensure that the airplane is operated
in an airworthy condition, as required
by the Federal Aviation Regulations. We
have not changed the AD in this regard.
Request To Refer to Replacement
Boeing also requests that we revise
the ‘‘title section’’ or ‘‘header section’’ to
refer to ‘‘Inspection/Replacement’’ in
lieu of ‘‘Inspection.’’ The commenter
states that the required action is not
only to inspect to determine the
manufacturing date marked on the
support bracket of the crew oxygen
cylinder, but also to replace certain
support assemblies.
We do not agree that any change to
the AD is needed with regard to this
request. We are unable to determine
what section of the AD that the
commenter is requesting be changed.
We note that the Summary section of
the NPRM states that the proposed AD
would require ‘‘inspecting the support
bracket of the crew oxygen cylinder
installation to determine the
manufacturing date marked on the
support, and performing corrective
action if necessary.’’ We also note that
the Relevant Service Information section
of the NPRM refers to the same actions
and further explains that ‘‘The
corrective action is replacing, with a
new support, any support with a
manufacturing date that is within a
certain range.’’ The heading of
paragraph (f) of the NPRM (and this AD)
describe the actions in paragraph (f) as

Request To Require Revised Service Information
Air Wisconsin requests that we delay issuing the final rule until
the manufacturer revises Inspection Service Bulletin (ISB) ISB.53-182,
dated March 16, 2005 (cited in the NPRM). The commenter reports that
BAE plans to revise the ISB to extend the inspection area after recent

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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
removing amendment 39-13421 (69 FR 869, January 7, 2004) and by adding
the following new airworthiness directive (AD):
2006-12-09 BAE Systems (Operations) Limited (Formerly British
Aerospace Regional Aircraft): Amendment 39-14634. Docket No. FAA-
2005-23284; Directorate Identifier 2005-NM-163-AD.
Effective Date
(a) This AD becomes effective July 17, 2006.
Affected ADs
(b) This AD supersedes AD 2004-01-07.
Applicability
(c) This AD applies to all BAE Systems (Operations) Limited
Model BAe 146-100A, -200A, and -300A series airplanes; and Model
Avro 146-RJ70A, 146-RJ85A, and 146-RJ100A airplanes; certificated in
any category.
Unsafe Condition
(d) This AD results from a report indicating that in some cases
the inspections required by AD 2004-01-07 revealed no damage, yet
frame corrosion and cracking were later found during scheduled
maintenance in the two forward fuselage frames 15 and 18. We are
issuing this AD to prevent reduced structural integrity of the
airplane.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Inspections
(f) Use high-frequency eddy current and detailed methods to
inspect for signs of corrosion (including cracks, blistering, or
flaking paint) of frames 15, 18, 41, and 43, in accordance with the
Accomplishment Instructions of BAE Systems (Operations) Limited
Inspection Service Bulletin ISB.53-182, dated March 16, 2005.
Inspect at the applicable time specified in 1.D. ``Compliance'' of
the service bulletin. Application of corrosion-preventive treatment,
in accordance with the service bulletin, extends the repetitive
inspection interval, as specified in Table 2 in 1.D. ``Compliance''
of the service bulletin.
Note 1: For the purposes of this AD, a detailed inspection is:
``An intensive examination of a specific item, installation, or
assembly to detect damage, failure, or irregularity. Available
lighting is normally supplemented with a direct source of good
lighting at an intensity deemed appropriate. Inspection aids such as
mirror, magnifying lenses, etc., may be necessary. Surface cleaning
and elaborate procedures may be required.''
Corrective Action
(g) If any discrepancy is found during any inspection required
by paragraph (f) of this AD: Before further flight, perform
applicable related investigative/corrective actions in accordance
with the Accomplishment Instructions of BAE Systems (Operations)
Limited Inspection Service Bulletin ISB.53-182, dated March 16,
2005, except as required by paragraph (h) of this AD.
Exceptions to Service Bulletin Specifications
(h) If the service bulletin referenced in this AD specifies to
contact the manufacturer for appropriate action, before further
flight, repair per a method approved by the Manager, International
Branch, ANM-116, Transport Airplane Directorate, FAA; or the Civil
Aviation Authority (or its delegated agent).
(i) Although the service bulletin referenced in this AD
specifies to submit information to the manufacturer, this AD does
not include such a requirement.
(j) Where the service bulletin specifies a compliance time after
the issuance of the service bulletin, this AD requires compliance
within the specified compliance time after the effective date of
this AD. And where the service bulletin specifies a compliance time
``since date of construction'' of the airplane, this AD requires
compliance since the date of issuance of the original standard
airworthiness certificate or the date of issuance of the original
export certificate of airworthiness.
Alternative Methods of Compliance (AMOCs)
(k)(1) The Manager, International Branch, ANM-116, has the
authority to approve AMOCs for this AD, if requested in
[[Page 33604]]
accordance with the procedures found in 14 CFR 39.19.
(2) Before using any AMOC approved in accordance with Sec.
39.19 on any airplane to which the AMOC applies, notify the
appropriate principal inspector in the FAA Flight Standards
Certificate Holding District Office.
