ACTION: Final rule.
AGENCY:
The FAA is adopting a new
airworthiness directive (AD) for certain
Boeing Model 757–200 and -300 series
airplanes. This AD requires replacing
certain electrical panels with certain
new panels. This AD results from a
report of some loose wire terminations
in the P50 panel that caused
intermittent indications in the flight
deck. We are issuing this AD to prevent
intermittent indications in the flight
deck, incorrect circuitry operation in the
panels, and airplane system
malfunctions that may adversely affect
the alternate flaps, alternate gear
extension, and fire extinguishing.
DATES: This AD becomes effective May
16, 2006.

Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to certain Boeing Model 757–200
and -300 series airplanes. That NPRM
was published in the Federal Register
on March 23, 2005 (70 FR 14592). That
NPRM proposed to require replacing
certain electrical panels with certain
new panels.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments received.
Support for the NPRM
The Boeing Company and American
Airlines support the NPRM.
Request to Address Defective Parts
Manufacturer Approval (PMA) Parts
The Modification and Replacement
Parts Association (MARPA) requests
that the NPRM be revised to cover
possible defective PMA alternative parts
and to identify the manufacturer of the
defective electrical panels, so that those
defective PMA parts also are subject to
the NPRM. MARPA states that the
electrical panels are identified in the
E:\FR\FM\11APR1.SGM
11APR1
wwhite on PROD1PC61 with NOTICES
18198
Federal Register / Vol. 71, No. 69 / Tuesday, April 11, 2006 / Rules and Regulations
NPRM by certain cryptic numbers such
as P1–1, P54, etc. MARPA is not clear
whether these are vendor part numbers
or some other designation such as
location or function.
MARPA also states that there are a
number of electrical panels known to
have been approved via the PMA route.
However, MARPA adds that it is not
possible to determine if such
alternatives exist in this case without
knowing the name of the actual
manufacturer and its part number and/
or the corresponding type certificate
holder part number. In addition,
MARPA states that, in general, service
bulletins almost exclusively refer to the
original equipment manufacturer’s
components and exclude possible PMA
alternatives. MARPA further states that
suppliers or repair facilities usually do
not have access to the proprietary
service bulletins and may not be able to
identify defective components. In such
cases, defective units could be returned
to service or supplied to operators.
We partially agree. We agree with
MARPA’s general request that, if we
know that an unsafe condition also
exists in PMA parts, an AD should
address those parts, as well as the
original parts. However, in the case of
this AD, the unsafe condition is the
result of a manufacturing error at The
Boeing Company, not a design
deficiency and thus, this AD does not
affect PMA parts.
MARPA’s remarks are timely in that
the Transport Airplane Directorate
currently is in the process of reviewing
this issue as it applies to transport
category airplanes. We acknowledge
that there may be other ways of
addressing this issue to ensure that
unsafe PMA parts are identified and
addressed. Once we have thoroughly
examined all aspects of this issue,
including input from industry, and have
made a final determination, we will
consider whether our policy regarding
addressing PMA parts in ADs needs to
be revised.
We do not agree with MARPA’s
request to identify the manufacturer and
part numbers of the subject electric
panels. As explained previously, we
have determined that the identified
unsafe condition is the result of a
manufacturing error, not a design
deficiency. Since the AD does not affect
PMA parts, and The Boeing Company’s
part numbers of the affected P1–1, P1–
3, P3–1, P3–3, P50, and P54 panels are
identified in paragraph 2., ‘‘MATERIAL
INFORMATION,’’ of the applicable
Boeing special attention service bulletin
listed in table 1 of the AD, it is
unnecessary to specify PMA part
numbers in the AD. Therefore, we have

made no change to the AD in this
regard.
economic burden on any operator nor
increase the scope of the AD.
Request To Revise Work Hour Estimate
The Air Transport Association (ATA)
of America, on behalf of one of its
members (Northwest Airlines, Inc.,),
states that the work hours necessary to
do the proposed replacement are
substantially more than the 12 work
hours specified in the NPRM. The ATA
indicates that this disparity may cause
some affected operators to accomplish
the proposed replacement during
unplanned, dedicated maintenance
visits. Northwest Airlines, Inc., notes
that the service bulletins in table 1 of
the NPRM specify 84 total hours to do
the proposed replacement. They also
notes that it took 162 hours to modify
one of their airplanes. They also state
that the main driver for the long hours
was the enormous functional check for
all of the disturbed systems and signals
when replacing certain panels.
We infer that the ATA and Northwest
Airlines, Inc., are requesting that we
revise the work hour estimate under
‘‘Costs of Compliance’’ in the NPRM.
We do not agree. The work hour
estimate describes only the direct costs
of the replacement required by this AD.
Based on the best data available, the
manufacturer provided the number of
work hours (12) necessary to do the
required replacement. This number
represents the time necessary to perform
only the replacement actually required
by this AD. We recognize that, in doing
the actions required by an AD, operators
may incur other costs in addition to the
direct costs. The cost analysis in AD
rulemaking actions, however, typically
does not include those costs (such as the
time required to gain access and close
up, time necessary for planning and
scheduling, tests, and time necessitated
by other administrative actions). Those
costs, which may vary significantly
among operators, are almost impossible
to calculate. Therefore, we have not
changed this AD regarding this issue.
Costs of Compliance
There are about 19 airplanes of the
affected design in the worldwide fleet.
This AD will affect about 13 airplanes
of U.S. registry. The required actions
will take about 12 work hours per
airplane, at an average labor rate of $65
per work hour. Required parts will cost
about $252,834 per airplane. Based on
these figures, the estimated cost of this
AD for U.S. operators is $3,296,982, or
$253,614 per airplane. However, we
have confirmed with the airplane
manufacturer that warranty remedies
may be available for all affected
airplanes. The manufacturer may cover
the cost of replacement parts and labor
costs associated with this AD, subject to
warranty conditions. As a result, the
costs attributable to this AD may be less
than stated above.
Clarification of Alternative Method of
Compliance (AMOC) Paragraph
We have revised this action to clarify
the appropriate procedure for notifying
the principal inspector before using any
approved AMOC on any airplane to
which the AMOC applies.
Conclusion
We have carefully reviewed the
available data, including the comments
received, and determined that air safety
and the public interest require adopting
the AD with the change described
previously. We have determined that
this change will neither increase the

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,

SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
BAE Systems (Operations) Limited
Model BAe 146 and Model Avro 146–
RJ airplanes. This AD requires
modifying the control cable duct on the
left bulkhead structure at frame 12, and,
for certain airplanes, the forward toilet
bulkhead structure. This AD results
from a structural analysis by the
manufacturer that revealed that rapid
decompression of the flight
compartment with the door closed
could cause structural deformation of
the left bulkhead structure at frame 12,
and of the attached cable duct structure.
The duct structure protects the cables
for the primary flight controls. We are
issuing this AD to prevent deformation
of the cable duct structure in the event
of a rapid decompression, which could
result in restriction of the primary flight
controls and consequent reduced
controllability of the airplane.
DATES: This AD becomes effective May
16, 2006.

Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to certain Boeing Model
757-200 and -300 series airplanes. That NPRM was published in the
Federal Register on March 23, 2005 (70 FR 14592). That NPRM proposed to
require replacing certain electrical panels with certain new panels.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Support for the NPRM
The Boeing Company and American Airlines support the NPRM.
Request to Address Defective Parts Manufacturer Approval (PMA) Parts
The Modification and Replacement Parts Association (MARPA) requests
that the NPRM be revised to cover possible defective PMA alternative
parts and to identify the manufacturer of the defective electrical
panels, so that those defective PMA parts also are subject to the NPRM.
MARPA states that the electrical panels are identified in the
[[Page 18198]]
NPRM by certain cryptic numbers such as P1-1, P54, etc. MARPA is not
clear whether these are vendor part numbers or some other designation
such as location or function.
MARPA also states that there are a number of electrical panels
known to have been approved via the PMA route. However, MARPA adds that
it is not possible to determine if such alternatives exist in this case
without knowing the name of the actual manufacturer and its part number
and/or the corresponding type certificate holder part number. In
addition, MARPA states that, in general, service bulletins almost
exclusively refer to the original equipment manufacturer's components
and exclude possible PMA alternatives. MARPA further states that
suppliers or repair facilities usually do not have access to the
proprietary service bulletins and may not be able to identify defective
components. In such cases, defective units could be returned to service
or supplied to operators.
We partially agree. We agree with MARPA's general request that, if
we know that an unsafe condition also exists in PMA parts, an AD should
address those parts, as well as the original parts. However, in the
case of this AD, the unsafe condition is the result of a manufacturing
error at The Boeing Company, not a design deficiency and thus, this AD
does not affect PMA parts.
MARPA's remarks are timely in that the Transport Airplane
Directorate currently is in the process of reviewing this issue as it
applies to transport category airplanes. We acknowledge that there may
be other ways of addressing this issue to ensure that unsafe PMA parts
are identified and addressed. Once we have thoroughly examined all
aspects of this issue, including input from industry, and have made a
final determination, we will consider whether our policy regarding
addressing PMA parts in ADs needs to be revised.
We do not agree with MARPA's request to identify the manufacturer
and part numbers of the subject electric panels. As explained
previously, we have determined that the identified unsafe condition is
the result of a manufacturing error, not a design deficiency. Since the
AD does not affect PMA parts, and The Boeing Company's part numbers of
the affected P1-1, P1-3, P3-1, P3-3, P50, and P54 panels are identified
in paragraph 2., ``MATERIAL INFORMATION,'' of the applicable Boeing
special attention service bulletin listed in table 1 of the AD, it is
unnecessary to specify PMA part numbers in the AD. Therefore, we have
made no change to the AD in this regard.
Request To Revise Work Hour Estimate
The Air Transport Association (ATA) of America, on behalf of one of
its members (Northwest Airlines, Inc.,), states that the work hours
necessary to do the proposed replacement are substantially more than
the 12 work hours specified in the NPRM. The ATA indicates that this
disparity may cause some affected operators to accomplish the proposed
replacement during unplanned, dedicated maintenance visits. Northwest
Airlines, Inc., notes that the service bulletins in table 1 of the NPRM
specify 84 total hours to do the proposed replacement. They also notes
that it took 162 hours to modify one of their airplanes. They also
state that the main driver for the long hours was the enormous
functional check for all of the disturbed systems and signals when
replacing certain panels.
We infer that the ATA and Northwest Airlines, Inc., are requesting
that we revise the work hour estimate under ``Costs of Compliance'' in
the NPRM. We do not agree. The work hour estimate describes only the
direct costs of the replacement required by this AD. Based on the best
data available, the manufacturer provided the number of work hours (12)
necessary to do the required replacement. This number represents the
time necessary to perform only the replacement actually required by
this AD. We recognize that, in doing the actions required by an AD,
operators may incur other costs in addition to the direct costs. The
cost analysis in AD rulemaking actions, however, typically does not
include those costs (such as the time required to gain access and close
up, time necessary for planning and scheduling, tests, and time
necessitated by other administrative actions). Those costs, which may
vary significantly among operators, are almost impossible to calculate.
Therefore, we have not changed this AD regarding this issue.
Clarification of Alternative Method of Compliance (AMOC) Paragraph
We have revised this action to clarify the appropriate procedure
for notifying the principal inspector before using any approved AMOC on
any airplane to which the AMOC applies.
Conclusion
We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD with the change described previously.
We have determined that this change will neither increase the economic
burden on any operator nor increase the scope of the AD.
Costs of Compliance
There are about 19 airplanes of the affected design in the
worldwide fleet. This AD will affect about 13 airplanes of U.S.
registry. The required actions will take about 12 work hours per
airplane, at an average labor rate of $65 per work hour. Required parts
will cost about $252,834 per airplane. Based on these figures, the
estimated cost of this AD for U.S. operators is $3,296,982, or $253,614
per airplane. However, we have confirmed with the airplane manufacturer
that warranty remedies may be available for all affected airplanes. The
manufacturer may cover the cost of replacement parts and labor costs
associated with this AD, subject to warranty conditions. As a result,
the costs attributable to this AD may be less than stated above.
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,
[[Page 18199]]
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.
