Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Boeing Model 767–300 and
–400ER series airplanes. This proposed
AD would require replacing the in-flight
entertainment cooling card, located in
the P50 card file in the main equipment
center, with a new, improved cooling
card. This proposed AD is prompted by
a report of an improperly designed
component on the in-flight
entertainment (IFE) cooling card, which
may cause the IFE cooling system to
incorrectly interpret signals from
airplane system interfaces. We are
proposing this AD to prevent failure of
the IFE cooling card to configure itself
correctly in response to input signals
from airplane system interfaces during a
forward cargo fire, which could result in
the IFE cooling fan causing smoke to
penetrate occupied areas of the airplane.
DATES: We must receive comments on
this proposed AD by February 22, 2005.

Discussion
We have received a report that on a
Boeing Model 767–400ER series
airplane, the field programmable gate
array component on the in-flight
entertainment (IFE) cooling card was
improperly designed. During flight, this
improperly designed component may
cause failure of the cooling card to
correctly configure itself in response to
input signals from airplane system
E:\FR\FM\05JAP1.SGM
05JAP1
726
Federal Register / Vol. 70, No. 3 / Wednesday, January 5, 2005 / Proposed Rules
interfaces. The report also indicates
that, during functional testing or other
ground operations, the improperly
designed component may cause
nuisance failure indications for
components in the IFE cooling system
that are monitored by the IFE cooling
card. If the IFE cooling card is
configured correctly, the IFE cooling fan
will shut down during an in-flight event
such as a cargo fire, smoke in the flight
deck, electronic equipment override
selection, or IFE equipment smoke.
Failure of the IFE cooling card to
configure itself correctly in response to
input signals from airplane system
interfaces during a forward cargo fire, if
not corrected, could result in the IFE
cooling fan causing smoke to penetrate
occupied areas of the airplane.
Boeing Model 767–300 series
airplanes use the same IFE cooling card
as that on the Boeing Model 767–400ER
series airplanes. Therefore, the Boeing
Model 767–300 series airplanes are
subject to the same unsafe condition.
Relevant Service Information
We have reviewed Boeing Special
Attention Service Bulletins 767–21–
0188 (for Model 767–300 series
airplanes) and 767–21–0189 (for Model
767–400ER series airplanes), both dated
May 27, 2004. The service bulletins
describe procedures for replacing the
IFE cooling card with a new, improved
cooling card. The service bulletins state
that the replacement and associated
functional test may be accomplished by
following the procedures in the
applicable Boeing 767 Airplane
Maintenance Manual, or an ‘‘operator’s
equivalent procedure.’’ Accomplishing
the actions specified in the service
information is intended to adequately
address the unsafe condition.
Difference Between the Proposed AD
and Service Information
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
‘‘Difference Between the Proposed AD
and Service Information.’’
Boeing Special Attention Service
Bulletins 767–21–0188 and 767–21–
0189 both specify that an operator’s
equivalent procedure may be used for
replacing the IFE cooling card, and for
accomplishing the associated functional
test. However, this proposed AD
specifies that replacement of the IFE
cooling card must be done according to
the procedures in the chapter/subject of
the applicable Boeing 767 Airplane
Maintenance Manual specified in the
service bulletins. This proposed AD
would allow operator’s equivalent
procedures to be used for the functional
test.
Costs of Compliance
There are about 32 airplanes of the
affected design in the worldwide fleet.
The following table provides the
estimated costs for U.S. operators to
comply with this proposed AD.
ESTIMATED COSTS
Replacement ....................................................................................
Authority for This Rulemaking
The FAA’s authority to issue rules
regarding aviation safety is found in
Title 49 of the United States Code.
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.
This rulemaking is promulgated
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
AD.
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.

AGENCY:
SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Boeing Model 767–200, –300,
and –300F series airplanes. This
proposed AD would require installing a
new, improved foam seal around certain
ducts in the forward cargo
compartment. This proposed AD is
prompted by the detection of incorrectly
installed smoke barrier seals around the
electrical/electronic equipment air
supply and exhaust ducts. We are
proposing this AD to prevent fire
extinguishing agent from leaking out of
the seals around the ducts in the
forward cargo compartment in the event
of an in-flight fire, which could result in
failure to extinguish the fire and
consequent smoke or fire extinguishing
agent entering a compartment occupied
by passengers or crew.

Discussion
We have received a report that on a Boeing Model 767-400ER series
airplane, the field programmable gate array component on the in-flight
entertainment (IFE) cooling card was improperly designed. During
flight, this improperly designed component may cause failure of the
cooling card to correctly configure itself in response to input signals
from airplane system
[[Page 726]]
interfaces. The report also indicates that, during functional testing
or other ground operations, the improperly designed component may cause
nuisance failure indications for components in the IFE cooling system
that are monitored by the IFE cooling card. If the IFE cooling card is
configured correctly, the IFE cooling fan will shut down during an in-
flight event such as a cargo fire, smoke in the flight deck, electronic
equipment override selection, or IFE equipment smoke. Failure of the
IFE cooling card to configure itself correctly in response to input
signals from airplane system interfaces during a forward cargo fire, if
not corrected, could result in the IFE cooling fan causing smoke to
penetrate occupied areas of the airplane.
Boeing Model 767-300 series airplanes use the same IFE cooling card
as that on the Boeing Model 767-400ER series airplanes. Therefore, the
Boeing Model 767-300 series airplanes are subject to the same unsafe
condition.
Relevant Service Information
We have reviewed Boeing Special Attention Service Bulletins 767-21-
0188 (for Model 767-300 series airplanes) and 767-21-0189 (for Model
767-400ER series airplanes), both dated May 27, 2004. The service
bulletins describe procedures for replacing the IFE cooling card with a
new, improved cooling card. The service bulletins state that the
replacement and associated functional test may be accomplished by
following the procedures in the applicable Boeing 767 Airplane
Maintenance Manual, or an ``operator's equivalent procedure.''
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
``Difference Between the Proposed AD and Service Information.''
Difference Between the Proposed AD and Service Information
Boeing Special Attention Service Bulletins 767-21-0188 and 767-21-
0189 both specify that an operator's equivalent procedure may be used
for replacing the IFE cooling card, and for accomplishing the
associated functional test. However, this proposed AD specifies that
replacement of the IFE cooling card must be done according to the
procedures in the chapter/subject of the applicable Boeing 767 Airplane
Maintenance Manual specified in the service bulletins. This proposed AD
would allow operator's equivalent procedures to be used for the
functional test.
Costs of Compliance
There are about 32 airplanes of the affected design in the
worldwide fleet. The following table provides the estimated costs for
U.S. operators to comply with this proposed AD.

Authority for This Rulemaking
The FAA's authority to issue rules regarding aviation safety is
found in Title 49 of the United States Code. 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.
This rulemaking is promulgated 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 AD.
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-2004-19989; Directorate Identifier 2004-NM-
151-AD.
Comments Due Date
(a) The Federal Aviation Administration (FAA) must receive
comments on this AD action by February 22, 2005.
Affected ADs
(b) None.
[[Page 727]]
Applicability
(c) This AD applies to Boeing Model 767-300 series airplanes as
listed in Boeing Special Attention Service Bulletin 767-21-0188,
dated May 27, 2004; and Boeing Model 767-400ER series airplanes, as
listed in Boeing Special Attention Service Bulletin 767-21-0189,
dated May 27, 2004; certificated in any category.
Unsafe Condition
(d) This AD was prompted by a report of an improperly designed
component on the in-flight entertainment (IFE) cooling card, which
may cause the IFE cooling system to incorrectly interpret signals
from airplane system interfaces. We are issuing this AD to prevent
failure of the IFE cooling card to configure correctly in response
to input signals from airplane system interfaces during a forward
cargo fire, which could result in the IFE cooling fan causing smoke
to penetrate occupied areas 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.
Replacement of IFE Cooling Card
(f) Within 18 months after the effective date of this AD:
Replace the IFE cooling card, part number (P/N) 285T1198-101,
located in the P50 card file in the main equipment center, with a
new, improved cooling card, P/N 285T1198-102. Do the replacement by
accomplishing all of the actions specified in the Accomplishment
Instructions of Boeing Special Attention Service Bulletin 767-21-
0188 (for Boeing Model 767-300 series airplanes); or 767-21-0189
(for Boeing Model 767-400ER series airplanes); both dated May 27,
2004; as applicable. Where the service bulletins state that the
replacement may be done using an ``operator's equivalent
procedure,'' the replacement must be done according to the
procedures in the chapter/subject of the applicable Boeing 767
Airplane Maintenance Manual specified in the service bulletins.
Parts Installation
(g) As of the effective date of this AD, no person may install
an IFE cooling card, P/N 285T1198-101, on any airplane.
Alternative Methods of Compliance (AMOCs)
(h) 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.
Issued in Renton, Washington, on December 27, 2004.
