VerDate jul<14>2003
16:54 Jun 14, 2005
Jkt 205001
Boeing Model 757–200 series airplanes.
This AD requires modifying the
frequency converters located in the
closet assembly in the passenger
compartment, and making various
wiring changes in and between the
closet assembly and forward purser
work station. This AD also requires
modifying the in-flight entertainment
system prior to or concurrently with the
modification of the frequency
converters. This AD is prompted by a
certification review that revealed a
frequency converter failure mode not
identified in the original system design.
We are issuing this AD to prevent a
short circuit between the frequency
converter output and the distribution
circuit breakers, which could result in
overheating and failure of adjacent
wiring and consequent adverse effects
on other systems sharing the affected
wire bundle.
DATES: This AD becomes effective July
20, 2005.
The incorporation by reference of
certain publications listed in the AD is
approved by the Director of the Federal
Register as of July 20, 2005.

an AD for certain Boeing Model 757–
200 series airplanes. That action,
published in the Federal Register on
September 29, 2004 (69 FR 58109),
proposed to require modifying the
frequency converters located in the
closet assembly in the passenger
compartment, and making various
wiring changes in and between the
closet assembly and forward purser
work station. That action also proposed
to require modifying the in-flight
entertainment system prior to or
concurrently with the modification of
the frequency converters.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments that have
been submitted on the proposed AD
from a single commenter.
Request To Clarify Discussion Section
The commenter states that the last
sentence in the second paragraph of the
Discussion section of the proposed AD
is unclear as written, and asks that it be
clarified. The commenter notes that the
sentence specifies ‘‘Therefore, all of
these models may be subject to the same
unsafe condition.’’ The commenter
states that the sentence should be
changed to read ‘‘Therefore, 757–200
series airplanes with frequency
converters may have an unsafe
condition.’’
We acknowledge the commenter’s
request for clarification of the
Discussion section of the proposed AD;
however, that section is not restated in
this final rule. In addition, the
certification review specified in the
Discussion section of the proposed AD
is of a Model 737–700C series airplane,
and the second paragraph merely
clarifies that the frequency converters
on certain Model 757–200 series
airplanes are identical to those on the
affected Model 737–700C series
airplanes.
Request To Clarify Number of
Airplanes in Costs of Compliance
Section
The commenter states that the
description for the number of airplanes
specified in the first paragraph of the
Costs of Compliance section of the
proposed AD is unclear as written, and
asks for clarification. The commenter
notes that the first paragraph specifies
‘‘This proposed AD would affect about
4 airplanes of U.S. registry and 4
airplanes worldwide.’’ The commenter
states that the paragraph should be
changed to read ‘‘This proposed AD
E:\FR\FM\15JNR1.SGM
15JNR1
Federal Register / Vol. 70, No. 114 / Wednesday, June 15, 2005 / Rules and Regulations
would affect 4 airplanes worldwide. All
four are of U.S. registry.’’
We agree with the commenter and
have changed the subject paragraph for
clarification.
Conclusion
We have carefully reviewed the
available data, including the comments
that have been submitted, and
determined that air safety and the
public interest require adopting the AD
as proposed.
Costs of Compliance
This AD affects 4 airplanes
worldwide; all of the airplanes are of
U.S. registry.
For airplanes listed in Group 1 of
Service Bulletin 757–25–0255: The
modification takes about 97 work hours
(including access, close-up, and test), at
an average labor rate of $65 per work
hour. Required parts will cost about
$10,710 per airplane. Based on these
figures, the estimated cost of the
modification for U.S. operators is
$17,015 per airplane.
For airplanes listed in Group 2 of
Service Bulletin 757–25–0255: The
modification takes about 105 work
hours (including access, close-up, and
test), at an average labor rate of $65 per
work hour. Required parts will cost
about $10,956 per airplane. Based on
these figures, the estimated cost of the
modification for U.S. operators is
$17,781 per airplane.
For airplanes listed in Group 1 of
Service Bulletin 757–24–0093: The
concurrent modification, if not
previously done, takes about 49 work
hours, at an average labor rate of $65 per
work hour. Required parts will cost
about $5,315 per airplane. Based on
these figures, the estimated cost of the
modification for U.S. operators is $8,500
per airplane.
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
VerDate jul<14>2003
16:54 Jun 14, 2005
Jkt 205001
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. See the ADDRESSES section for
a location to examine the regulatory
evaluation.

ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Boeing Model 747–200F and –400 series
airplanes; Model 767–400ER series
airplanes; and Model 777 series
airplanes. This AD requires replacing
the frequency converter(s) used to
supply electrical power for utility
outlets (for the galley, medical
equipment, or personal computers) with
modified frequency converter(s). This
AD also requires any specified action
and related concurrent actions, as
necessary. This AD is prompted by a
report that a hard short condition
between the frequency converter’s
output and its downstream circuit
breakers will produce a continuous
current that could cause the undersized
output wiring to overheat. We are
issuing this AD to prevent the
overheating of the frequency converter’s
undersized output wiring, which could
lead to the failure of a wire bundle, and
consequent adverse effects on other
systems sharing the affected wire
bundle.
This AD becomes effective July
20, 2005.
The incorporation by reference of
certain publications listed in the AD is
approved by the Director of the Federal
Register as of July 20, 2005.

SUPPLEMENTARY INFORMATION: The FAA
proposed to amend 14 CFR part 39 with
an AD for certain Boeing Model 747–
200F and –400 series airplanes; Model
767–400ER series airplanes; and Model
777 series airplanes. That action,
published in the Federal Register on
September 13, 2004 (69 FR 55120),
proposed to require replacing the
frequency converter(s) used to supply
power for utility outlets (for the galley,
medical equipment, or personal
computers) with modified frequency
converter(s); and any other specified
action and related concurrent actions, as
necessary.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments that have
been submitted on the proposed AD.
Request To Revise Applicability To List
Frequency Converters
One commenter asks ‘‘* * * why not
write the AD against the part instead of
the aircraft?’’ and suggests that listing
the frequency converter by
manufacturer and part number may
allow detection of similar problems on
other aircraft and possible parts
manufacturer approved (PMA)
alternative units.
We disagree with revising the
applicability. PMA parts frequently
have a part numbering scheme different
from that of the original manufacturer.
For this reason, writing the AD against
the part number may not accurately
identify the PMA parts. Should we
PO 00000
Frm 00020
Fmt 4700
Sfmt 4700
become aware of PMA parts that have
similar characteristics as those
addressed in this AD, we would
consider further rulemaking.
The FAA’s practice regarding unsafe
conditions that result from the
installation of a particular part in
specific makes and models of airplanes
is to issue an AD that applies to the
affected airplane models. In doing so,
U.S. operators of those airplanes will be
notified directly of the unsafe condition
and the action required to correct it.
While we assume that operators can
identify the airplane models they
operate, they may not be aware of
specific items installed on those
airplanes. Therefore, specifying the
airplane models in the applicability as
the subject of the AD prevents an
operator’s ‘‘unknowing failure to
comply’’ with the AD. We have not
changed the final rule regarding this
issue.
Request To Add Airplane Models to the
Applicability of the AD
One commenter requests that certain
Boeing Model 767–300 series airplanes
be added to the applicability of this AD.
Boeing has published Boeing Service
Bulletin 767–25–0334, Revision 1, dated
June 19, 2003, which addresses the
same unsafe condition on some Model
767–300 series airplanes that were also
delivered with affected frequency
converters.
We agree that the Model 767–300
series airplanes are affected by the
unsafe condition. We inadvertently
omitted the service bulletin in the
proposed AD. However, we disagree
with revising the applicability of this
AD, because we are considering a
separate rulemaking action for the
Model 767–300 series airplanes. A
notice of proposed rulemaking for the
Model 767–300 series airplanes was
published in the Federal Register on
March 17, 2005 (70 FR 12986). If we
revise the applicability of this AD to add
Model 767–300 series airplanes, we
would need to reissue this AD as a
revised notice. In light of the time that
would be needed to reissue the
proposed AD, and in consideration of
the amount of time that has already
elapsed since we issued the original
notice, we have determined that further
delay of this AD is not appropriate.
Request for Change of Terminology
One commenter requests that the
phrase ‘‘continuous circuit’’ in the
Summary section of the proposed AD be
changed to ‘‘continuous current.’’ The
commenter provides no reason/
justification.

Comments
We provided the public the opportunity to participate in the

Request To Clarify Discussion Section
The commenter states that the last sentence in the second paragraph
of the Discussion section of the proposed AD is unclear as written, and
asks that it be clarified. The commenter notes that the sentence
specifies ``Therefore, all of these models may be subject to the same
unsafe condition.'' The commenter states that the sentence should be
changed to read ``Therefore, 757-200 series airplanes with frequency
converters may have an unsafe condition.''
We acknowledge the commenter's request for clarification of the
Discussion section of the proposed AD; however, that section is not
restated in this final rule. In addition, the certification review
specified in the Discussion section of the proposed AD is of a Model
737-700C series airplane, and the second paragraph merely clarifies
that the frequency converters on certain Model 757-200 series airplanes
are identical to those on the affected Model 737-700C series airplanes.
Request To Clarify Number of Airplanes in Costs of Compliance Section
The commenter states that the description for the number of
airplanes specified in the first paragraph of the Costs of Compliance
section of the proposed AD is unclear as written, and asks for
clarification. The commenter notes that the first paragraph specifies
``This proposed AD would affect about 4 airplanes of U.S. registry and
4 airplanes worldwide.'' The commenter states that the paragraph should
be changed to read ``This proposed AD
[[Page 34645]]
would affect 4 airplanes worldwide. All four are of U.S. registry.''
We agree with the commenter and have changed the subject paragraph
for clarification.
Conclusion
We have carefully reviewed the available data, including the
comments that have been submitted, and determined that air safety and
the public interest require adopting the AD as proposed.
Costs of Compliance
This AD affects 4 airplanes worldwide; all of the airplanes are of
U.S. registry.
For airplanes listed in Group 1 of Service Bulletin 757-25-0255:
The modification takes about 97 work hours (including access, close-up,
and test), at an average labor rate of $65 per work hour. Required
parts will cost about $10,710 per airplane. Based on these figures, the
estimated cost of the modification for U.S. operators is $17,015 per
airplane.
For airplanes listed in Group 2 of Service Bulletin 757-25-0255:
The modification takes about 105 work hours (including access, close-
up, and test), at an average labor rate of $65 per work hour. Required
parts will cost about $10,956 per airplane. Based on these figures, the
estimated cost of the modification for U.S. operators is $17,781 per
airplane.
For airplanes listed in Group 1 of Service Bulletin 757-24-0093:
The concurrent modification, if not previously done, takes about 49
work hours, at an average labor rate of $65 per work hour. Required
parts will cost about $5,315 per airplane. Based on these figures, the
estimated cost of the modification for U.S. operators is $8,500 per
airplane.
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. See the ADDRESSES section for a location to
examine the regulatory evaluation.

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 FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2005-12-11 Boeing: Amendment 39-14127. Docket No. FAA-2004-19203;
Directorate Identifier 2004-NM-109-AD.
Effective Date
(a) This AD becomes effective July 20, 2005.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Model 757-200 series airplanes,
certificated in any category, as listed in Boeing Service Bulletin
757-25-0255, dated December 11, 2003.
Unsafe Condition
(d) This AD was prompted by a certification review that revealed
a frequency converter failure mode not identified in the original
system design. We are issuing this AD to prevent a short circuit
between the frequency converter output and the distribution circuit
breakers, which could result in overheating and failure of adjacent
wiring and consequent degraded operation of airplane systems.
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.
Modification
(f) For all airplanes: Within 18 months after the effective date
of this AD modify the frequency converters located in the closet
assembly in the passenger compartment by doing all the applicable
actions in accordance with the Accomplishment Instructions of Boeing
Service Bulletin 757-25-0255, dated December 11, 2003.
Prior or Concurrent Modification
(g) For Group 1 airplanes identified in Boeing Service Bulletin
757-24-0093, dated August 14, 2003: Before or concurrent with
accomplishment of paragraph (f) of this AD, modify the in-flight
entertainment system by doing all the applicable actions in
accordance with Boeing Service Bulletin 757-24-0093, dated August
14, 2003.
Part Installation
(h) As of the effective date of this AD, no person may install a
frequency converter having part number 1-002-0102-0730 on any
airplane unless that frequency converter has been modified as
required by paragraph (f) of this AD.
Alternative Methods of Compliance (AMOCs)
(i) The Manager, Seattle Aircraft Certification Office, FAA, has
the authority to approve AMOCs for this AD, if requested in
accordance with the procedures found in 14 CFR 39.19.
Material Incorporated by Reference
(j) You must use Boeing Service Bulletin 757-25-0255, dated
December 11, 2003; and Boeing Service Bulletin 757-24-0093, dated
