ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Boeing transport category
airplanes. This proposed AD would
require inspecting to determine if
certain galleys and closets are installed,
and replacing the spiral wire wrapping
of the electrical cables of the galleys and
closets with new spiral wire wrapping
if necessary. This proposed AD results
from testing and reports from the
manufacturer indicating unacceptable
flammability properties of wire
wrapping installed in certain galleys
and closets. We are proposing this AD
to prevent fire propagation or smoke in
the cabin area due to electrical arcing or
sparking and ignition of the spiral wire
wrapping.

Discussion
We received reports of testing by the
manufacturer indicating unacceptable
flammability properties of the spiral
wire wrapping of the electrical cables in
certain galleys and closets on various
Boeing transport category airplanes. The
existing spiral wire wrapping of certain
galleys and closets was not tested for
flammability standards and may not
self-extinguish in the event of a fire.
Electrical arcing or sparking and
ignition of the spiral wire wrapping
could result in fire propagation or
smoke in the cabin area.
Relevant Service Information
We have reviewed the service
information identified in the following
table.

Special Attention Service Bulletin 767–25–0297 ........................................................................................
Special Attention Service Bulletin 777–25–0180 ........................................................................................
The service bulletins and special
attention service bulletins describe
procedures for replacing existing spiral
wire wrapping of the electrical cables of
the galleys and closets with new spiral
protective wrapping that has been
shown to meet certain flammability
testing requirements. The procedures
also describe installing a modification
placard to indicate that new spiral
protective wrapping has been installed.
Each of the service bulletins reference
Dreissen Aircraft Interior Systems
Service Bulletin SB 25–442, Revision E,
dated April 29, 2004, and Showa
Aircraft Industry Co., Ltd., Service
Bulletin SB 25–30–111, dated December
11, 2000, as applicable, as additional
sources of service information.
Accomplishing the actions specified in
the service information is intended to
adequately address the unsafe
condition.
FAA’s Determination and Requirements
of the Proposed AD
We have evaluated all pertinent
information and identified an unsafe
condition that is likely to exist or
develop on other airplanes of this same
type design. Therefore, we are
proposing this AD, which would require
accomplishing the actions specified in
the service information described
previously, except as discussed under
‘‘Differences Between the Proposed AD
and the Service Information.’’
Differences Between the Proposed AD
and the Service Information
Each of the Boeing service bulletins
referenced in this proposed AD specify
certain Boeing series airplanes.
VerDate Aug<31>2005
15:27 Oct 06, 2005
Jkt 208001
However, this proposed AD is
applicable to all the airplane models
specified. Since galleys and closets may
be removed from one airplane and
installed in another airplane, this
proposed AD would also require an
inspection to determine if certain
galleys or closets are installed, or a
maintenance record check of the
airplane to determine if certain galleys
or closets are installed.
Although the Boeing service bulletins
refer to accomplishment of certain
Driessen Aircraft Interior Systems and
Showa service bulletins, or ‘‘the latest
FAA-approved revision,’’ this proposed
AD would require accomplishment of
the Driessen Aircraft Interior Systems
and Showa service bulletins specified in
this proposed AD. Using the phrase, ‘‘or
later FAA-approved revision,’’ violates
Office of the Federal Register
regulations for approving materials that
are incorporated by reference. However,
affected operators may request approval
to use a later revision of the referenced
service bulletin as an alternative method
of compliance, under the provisions of
paragraph (j) of the proposed AD.
The Boeing service bulletins also
specify an imprecise compliance time
for replacing the spiral protective
wrapping of the electrical cables of the
galley, i.e., ‘‘at the next heavy
maintenance check.’’ This proposed AD
would require replacement within 72
months after the effective date of the
AD, and we have coordinated this
compliance time with the manufacturer.
Additionally, for clarification and for
the purposes of this proposed AD, the
use of the term ‘‘galley’’ includes the
terms ‘‘buffet’’ and ‘‘closets’’ referenced

in certain service information specified
in this proposed AD.
Costs of Compliance
There are about 5,177 airplanes of the
affected design in the worldwide fleet.
This proposed AD would affect about
2,621 airplanes of U.S. registry. The
proposed inspection to determine part
numbers of the galleys would take about
1 work hour per galley, at an average
labor rate of $65 per work hour. Some
airplanes have only one galley and some
have up to 11 galleys. With the
exception of Boeing Model 777–300
airplanes, we estimate the cost of the
inspection proposed in this AD for U.S.
operators to be between $65 and $715
per airplane.
If an operator is required to replace
the spiral protective wrapping of the
electrical cables of the galley, we
estimate that cost to be as follows:
1. For Dreissen galleys: About two
work hours per galley, at an average
labor rate of $65 per work hour, and the
estimated cost for the new spiral
protective wrapping to be about $1,450,
per galley. The estimated total cost
would be about $1,580, per galley.
2. For Showa galleys: About 20 work
hours per galley, at an average labor rate
of $65 per work hour, and the estimated
cost of the new spiral protective
wrapping to be about $1,550, per galley.
The estimated total cost would be about
$2,850, per galley.
Currently, there are no Boeing Model
777–300 airplanes with the subject
galleys on the U.S. Register. However, if
a Model 777–300 is imported and
placed on the U.S. Register in the future,
the required actions would take about 1

work hour per galley, at an average labor
rate of $65 per work hour.
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. See the ADDRESSES
section for a location to examine the
regulatory evaluation.
Applicability
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation
safety, Safety.
Unsafe Condition
The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
(d) This proposed AD results from testing
and reports from the manufacturer indicating
unacceptable flammability properties of wire
wrapping installed in certain galleys and
closets. We are proposing this AD to prevent
fire propagation or smoke in the cabin area
due to electrical arcing or sparking and
ignition of the spiral wire wrapping.

SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Bombardier Model CL–600–
2C10 (Regional Jet Series 700, 701, &
702), CL–600–2D15 (Regional Jet Series
705), and CL–600–2D24 (Regional Jet
Series 900) airplanes. This proposed AD
would require repetitive inspections for
cracking or fracturing of the output links
of the power control unit (PCU) for the
ailerons, and related investigative and
corrective actions if necessary. This
proposed AD results from reports of
fractured output links of the aileron
PCU. We are proposing this AD to
prevent failure of an output link of the
aileron PCU, which, if both links on one
aileron fail, could result in reduced
lateral control of the airplane.

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Boeing transport category airplanes. This proposed AD would
require inspecting to determine if certain galleys and closets are
installed, and replacing the spiral wire wrapping of the electrical
cables of the galleys and closets with new spiral wire wrapping if
necessary. This proposed AD results from testing and reports from the
manufacturer indicating unacceptable flammability properties of wire
wrapping installed in certain galleys and closets. We are proposing
this AD to prevent fire propagation or smoke in the cabin area due to
electrical arcing or sparking and ignition of the spiral wire wrapping.
DATES: We must receive comments on this proposed AD by November 21,
2005.

Discussion
We received reports of testing by the manufacturer indicating
unacceptable flammability properties of the spiral wire wrapping of the
electrical cables in certain galleys and closets on various Boeing
transport category airplanes. The existing spiral wire wrapping of
certain galleys and closets was not tested for flammability standards
and may not self-extinguish in the event of a fire. Electrical arcing
or sparking and ignition of the spiral wire wrapping could result in
fire propagation or smoke in the cabin area.
Relevant Service Information
We have reviewed the service information identified in the
following table.

------------------------------------------------------------------------
The service bulletins and special attention service bulletins
describe procedures for replacing existing spiral wire wrapping of the
electrical cables of the galleys and closets with new spiral protective
wrapping that has been shown to meet certain flammability testing
requirements. The procedures also describe installing a modification
placard to indicate that new spiral protective wrapping has been
installed. Each of the service bulletins reference Dreissen Aircraft
Interior Systems Service Bulletin SB 25-442, Revision E, dated April
29, 2004, and Showa Aircraft Industry Co., Ltd., Service Bulletin SB
25-30-111, dated December 11, 2000, as applicable, as additional
sources of service information. Accomplishing the actions specified in
the service information is intended to adequately address the unsafe
condition.
FAA's Determination and Requirements of the Proposed AD
We have evaluated all pertinent information and identified an
unsafe condition that is likely to exist or develop on other airplanes
of this same type design. Therefore, we are proposing this AD, which
would require accomplishing the actions specified in the service
information described previously, except as discussed under
``Differences Between the Proposed AD and the Service Information.''
Differences Between the Proposed AD and the Service Information
Each of the Boeing service bulletins referenced in this proposed AD
specify certain Boeing series airplanes. However, this proposed AD is
applicable to all the airplane models specified. Since galleys and
closets may be removed from one airplane and installed in another
airplane, this proposed AD would also require an inspection to
determine if certain galleys or closets are installed, or a maintenance
record check of the airplane to determine if certain galleys or closets
are installed.
Although the Boeing service bulletins refer to accomplishment of
certain Driessen Aircraft Interior Systems and Showa service bulletins,
or ``the latest FAA-approved revision,'' this proposed AD would require
accomplishment of the Driessen Aircraft Interior Systems and Showa
service bulletins specified in this proposed AD. Using the phrase, ``or
later FAA-approved revision,'' violates Office of the Federal Register
regulations for approving materials that are incorporated by reference.
However, affected operators may request approval to use a later
revision of the referenced service bulletin as an alternative method of
compliance, under the provisions of paragraph (j) of the proposed AD.
The Boeing service bulletins also specify an imprecise compliance
time for replacing the spiral protective wrapping of the electrical
cables of the galley, i.e., ``at the next heavy maintenance check.''
This proposed AD would require replacement within 72 months after the
effective date of the AD, and we have coordinated this compliance time
with the manufacturer.
Additionally, for clarification and for the purposes of this
proposed AD, the use of the term ``galley'' includes the terms
``buffet'' and ``closets'' referenced in certain service information
specified in this proposed AD.
Costs of Compliance
There are about 5,177 airplanes of the affected design in the
worldwide fleet. This proposed AD would affect about 2,621 airplanes of
U.S. registry. The proposed inspection to determine part numbers of the
galleys would take about 1 work hour per galley, at an average labor
rate of $65 per work hour. Some airplanes have only one galley and some
have up to 11 galleys. With the exception of Boeing Model 777-300
airplanes, we estimate the cost of the inspection proposed in this AD
for U.S. operators to be between $65 and $715 per airplane.
If an operator is required to replace the spiral protective
wrapping of the electrical cables of the galley, we estimate that cost
to be as follows:
1. For Dreissen galleys: About two work hours per galley, at an
average labor rate of $65 per work hour, and the estimated cost for the
new spiral protective wrapping to be about $1,450, per galley. The
estimated total cost would be about $1,580, per galley.
2. For Showa galleys: About 20 work hours per galley, at an average
labor rate of $65 per work hour, and the estimated cost of the new
spiral protective wrapping to be about $1,550, per galley. The
estimated total cost would be about $2,850, per galley.
Currently, there are no Boeing Model 777-300 airplanes with the
subject galleys on the U.S. Register. However, if a Model 777-300 is
imported and placed on the U.S. Register in the future, the required
actions would take about 1
[[Page 58630]]
work hour per galley, at an average labor rate of $65 per work hour.
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. 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, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 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]
2. The FAA amends Sec. 39.13 by adding the following new
airworthiness directive (AD):
Boeing: Docket No. FAA-2005-22628; Directorate Identifier 2005-NM-
056-AD.
Comments Due Date
(a) The Federal Aviation Administration (FAA) must receive
comments on this AD action by November 21, 2005.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Boeing transport category airplanes
equipped with certain Driessen Aircraft Interior Systems or Showa
galleys, certificated in any category; as identified in paragraphs
(c)(1) through (c)(5) inclusive of this AD.
(1) Model 737-300, -400, -500, -700, and -800 series airplanes;
(2) Model 747-400 and 747-400F series airplanes;
(3) Model 757-200 series airplanes;
(4) Model 767-300 series airplanes;
(5) Model 777-300 series airplanes.
Unsafe Condition
(d) This proposed AD results from testing and reports from the
manufacturer indicating unacceptable flammability properties of wire
wrapping installed in certain galleys and closets. We are proposing
this AD to prevent fire propagation or smoke in the cabin area due
to electrical arcing or sparking and ignition of the spiral wire
wrapping.
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.
Note 1: For clarification and for the purposes of this AD, the
use of the term ``galley'' also includes the terms ``buffet'' and
``closets'' that are referenced in certain service information
specified in this AD.
Determination of Part Installation
(f) Within 72 months after the effective date of this AD,
inspect the galleys to determine if any of the part numbers (P/Ns)
installed are identified in the applicable service information
specified in Table 1 of this AD. Instead of inspecting the galleys
to determine if the P/Ns are installed, a review of airplane
maintenance records is acceptable if the P/Ns can be positively
determined from that review.
