Discussion
On February 5, 2002, we issued AD
2002–03–07, amendment 39–12648 (67
FR 6852, February 14, 2002), for certain
VerDate Aug<31>2005
18:28 Mar 24, 2006
Jkt 208001
BAE Systems (Operations) Limited
Model BAe 146 and Avro 146–RJ series
airplanes. That AD requires a one-time
inspection to detect corrosion of the flap
structure and machined ribs, corrective
actions if necessary, and reprotection of
the rib boss bores. That AD resulted
from corrosion at various locations
within the flap structure and machined
ribs. We issued that AD to detect and
correct corrosion in the flap structure
and machined ribs, which could result
in reduced structural integrity of the
airplane.
Relevant Service Information
AD 2002–03–07 cited BAE Systems
(Operations) Limited Inspection Service
Bulletin ISB.57–066, dated May 15,
2001. Revision 2, dated March 18, 2004,
of this service bulletin provides
procedures for additional inspection for
corrosion and reprotection of the rib
boss bores and faces. If the corrosion
extended into the boss bores, the service
bulletin specifies a ‘‘flaps-off’’
inspection; otherwise the service
bulletin specifies a ‘‘flaps-on’’
inspection. Corrective actions for
corrosion include repairing (blending),
replacing corroded components with
new components, and contacting the
manufacturer for repair instructions,
depending on the extent and location of
the corrosion. For airplanes with no
corrosion found during the initial
inspection, no further work is necessary.
Accomplishing the actions specified in
the service information is intended to
adequately address the unsafe
condition. The Civil Aviation Authority
(CAA), which is the airworthiness
authority of the United Kingdom,
mandated the service information and
issued British airworthiness directive
G–2005–0018, dated July 20, 2005, to
ensure the continued airworthiness of
these airplanes in the United Kingdom.
FAA’s Determination and Requirements
of the Proposed AD
These airplane models are
manufactured in the United Kingdom
and are type certificated for operation in
the United States under the provisions
of section 21.29 of the Federal Aviation
Regulations (14 CFR 21.29) and the
applicable bilateral airworthiness
agreement. Pursuant to this bilateral
airworthiness agreement, the CAA has
kept the FAA informed of the situation
described above. We have examined the
CAA’s findings, evaluated all pertinent
information, and determined that AD
action is necessary for airplanes of this
type design that are certificated for
operation in the United States.
PO 00000
Frm 00031
Fmt 4702
Sfmt 4702

This proposed AD would supersede
AD 2002–03–07. This proposed AD
would require a review of the airplane
records for the results, if any, of the
inspection required by AD 2002–03–07.
For airplanes not already inspected in
accordance with AD 2002–03–07, this
proposed AD would require an initial
inspection. If the results of the initial
inspection required by this proposed
AD or AD 2002–03–07 reveal corrosion,
this proposed AD would require the
related investigative/corrective actions
specified in Revision 2 of the service
bulletin, described previously, except as
discussed below.
Differences Between the Proposed Rule
and the British Airworthiness Directive/
Service Bulletin
The service bulletin specifies to
contact the manufacturer for
instructions on how to repair certain
conditions, but this proposed AD would
require repairing those conditions using
a method that we or the CAA (or its
delegated agent) approve. In light of the
type of repair that would be required to
address the unsafe condition, and
consistent with existing bilateral
airworthiness agreements, we have
determined that, for this proposed AD,
a repair we or the CAA approve would
be acceptable for compliance with this
proposed AD.
The British airworthiness directive
specifies that all Model BAe 146 and
Avro RJ series airplanes are affected. But
this proposed AD, as well as Inspection
Service Bulletin ISB.57–066, Revision 2,
would exclude those airplanes modified
by BAE Systems Modification
HCM01694F. The CAA is aware of this
discrepancy and agreed with the intent
to so limit the applicability.
Clarification of Inspection Terminology
The inspection specified in the
service bulletin is referred to as a
‘‘general visual inspection’’ in this
proposed AD. Note 1 of this proposed
AD defines this type of inspection.
Explanation of Change to Applicability
We have revised the applicability of
the existing AD to identify model
designations as published in the most
recent type certificate data sheet for the
affected models.
Costs of Compliance
The following table provides the
estimated costs for U.S. operators to
comply with this proposed AD. This
proposed AD would affect about 35
airplanes of U.S. registry.

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
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would 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 the proposed regulation:
1. Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
2. Is not a ‘‘significant rule’’ under the
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 proposed AD and placed it in the
AD docket. See the ADDRESSES section
for a location to examine the regulatory
evaluation.

ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
SUMMARY: The FAA proposes to
supersede an existing airworthiness
directive (AD) that applies to certain
Airbus Model A300 B4–600 and A300
C4–600 series airplanes. The existing
AD currently requires a one-time
inspection to detect damage of the
pump diffuser guide slots (bayonet) of
the center tank fuel pumps, the pump
diffuser housings, and the pump
canisters; repetitive inspections to
detect damage of the fuel pumps and the
fuel pump canisters; and corrective
action, if necessary. This proposed AD
would add, for new airplanes, repetitive
inspections of the pump bodies for
cracking, damage, and missing and
broken fasteners; repetitive inspections
of the fuel pump canisters for a cracked
flange web; and corrective actions if
necessary. For all airplanes, this
proposed AD would also add
replacement of the fuel pump canisters
with new reinforced fuel pump
canisters, which ends the repetitive
inspections. This proposed AD results
from fuel system reviews conducted by
the manufacturer. We are proposing this
AD to detect and correct damage of the
center tank fuel pumps and fuel pump
canisters, which could result in
separation of a pump from its electrical
motor housing, loss of flame trap
capability, and a possible fuel ignition
source in the center fuel tank.
DATES: We must receive comments on
this proposed AD by April 26, 2006.

BAe 146 and Avro 146-RJ Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede an existing airworthiness
directive (AD) that applies to certain BAE Systems (Operations) Limited
Model BAe 146 and Avro 146-RJ airplanes. The existing AD currently
requires a one-time inspection to detect corrosion of the flap
structure and machined ribs, corrective actions if necessary, and
reprotection of the rib boss bores. This proposed AD would require a
records review of the results of that inspection, and an additional
inspection and related investigative/corrective action if necessary.
This proposed AD results from the development of an improved inspection
for corrosion in the subject area. We are proposing this AD to detect
and correct corrosion in the flap structure and machined ribs, which
could result in reduced structural integrity of the airplane.
DATES: We must receive comments on this proposed AD by April 26, 2006.
ADDRESSES: Use one of the following addresses to submit comments on
this proposed AD.

Discussion
On February 5, 2002, we issued AD 2002-03-07, amendment 39-12648
(67 FR 6852, February 14, 2002), for certain BAE Systems (Operations)
Limited Model BAe 146 and Avro 146-RJ series airplanes. That AD
requires a one-time inspection to detect corrosion of the flap
structure and machined ribs, corrective actions if necessary, and
reprotection of the rib boss bores. That AD resulted from corrosion at
various locations within the flap structure and machined ribs. We
issued that AD to detect and correct corrosion in the flap structure
and machined ribs, which could result in reduced structural integrity
of the airplane.
Relevant Service Information
AD 2002-03-07 cited BAE Systems (Operations) Limited Inspection
Service Bulletin ISB.57-066, dated May 15, 2001. Revision 2, dated
March 18, 2004, of this service bulletin provides procedures for
additional inspection for corrosion and reprotection of the rib boss
bores and faces. If the corrosion extended into the boss bores, the
service bulletin specifies a ``flaps-off'' inspection; otherwise the
service bulletin specifies a ``flaps-on'' inspection. Corrective
actions for corrosion include repairing (blending), replacing corroded
components with new components, and contacting the manufacturer for
repair instructions, depending on the extent and location of the
corrosion. For airplanes with no corrosion found during the initial
inspection, no further work is necessary. Accomplishing the actions
specified in the service information is intended to adequately address
the unsafe condition. The Civil Aviation Authority (CAA), which is the
airworthiness authority of the United Kingdom, mandated the service
information and issued British airworthiness directive G-2005-0018,
dated July 20, 2005, to ensure the continued airworthiness of these
airplanes in the United Kingdom.
FAA's Determination and Requirements of the Proposed AD
These airplane models are manufactured in the United Kingdom and
are type certificated for operation in the United States under the
provisions of section 21.29 of the Federal Aviation Regulations (14 CFR
21.29) and the applicable bilateral airworthiness agreement. Pursuant
to this bilateral airworthiness agreement, the CAA has kept the FAA
informed of the situation described above. We have examined the CAA's
findings, evaluated all pertinent information, and determined that AD
action is necessary for airplanes of this type design that are
certificated for operation in the United States.
This proposed AD would supersede AD 2002-03-07. This proposed AD
would require a review of the airplane records for the results, if any,
of the inspection required by AD 2002-03-07. For airplanes not already
inspected in accordance with AD 2002-03-07, this proposed AD would
require an initial inspection. If the results of the initial inspection
required by this proposed AD or AD 2002-03-07 reveal corrosion, this
proposed AD would require the related investigative/corrective actions
specified in Revision 2 of the service bulletin, described previously,
except as discussed below.
Differences Between the Proposed Rule and the British Airworthiness
Directive/Service Bulletin
The service bulletin specifies to contact the manufacturer for
instructions on how to repair certain conditions, but this proposed AD
would require repairing those conditions using a method that we or the
CAA (or its delegated agent) approve. In light of the type of repair
that would be required to address the unsafe condition, and consistent
with existing bilateral airworthiness agreements, we have determined
that, for this proposed AD, a repair we or the CAA approve would be
acceptable for compliance with this proposed AD.
The British airworthiness directive specifies that all Model BAe
146 and Avro RJ series airplanes are affected. But this proposed AD, as
well as Inspection Service Bulletin ISB.57-066, Revision 2, would
exclude those airplanes modified by BAE Systems Modification HCM01694F.
The CAA is aware of this discrepancy and agreed with the intent to so
limit the applicability.
Clarification of Inspection Terminology
The inspection specified in the service bulletin is referred to as
a ``general visual inspection'' in this proposed AD. Note 1 of this
proposed AD defines this type of inspection.
Explanation of Change to Applicability
We have revised the applicability of the existing AD to identify
model designations as published in the most recent type certificate
data sheet for the affected models.
Costs of Compliance
The following table provides the estimated costs for U.S. operators
to comply with this proposed AD. This proposed AD would affect about 35
airplanes of U.S. registry.

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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 the proposed
regulation:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the 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 proposed 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
