Modified by Supplemental Type Certificate ST01869AT-D
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) that
is applicable to all Boeing Model 767-300 series airplanes modified by
supplemental type certificate ST01869AT-D. This action requires
modifying the passenger entertainment system (PES) and revising the
airplane flight manual. This action is necessary to ensure that the
airplane crew is able to remove electrical power from the PES when
necessary and is advised of appropriate procedures for such action.
Inability to remove power from the PES during a non-normal or emergency
situation could result in inability to control smoke or fumes in the
airplane flight deck or cabin. This action is intended to address the
identified unsafe condition.

SUPPLEMENTARY INFORMATION:
Discussion
The Federal Aviation Administration (FAA) recently completed a
review of in-flight entertainment (IFE) systems certified by
supplemental type certificate (STC) and installed on transport category
airplanes. The review focused on the interface between the IFE system
and airplane electrical system, with the objective of determining if
any unsafe conditions exist with regard to the interface. STCs issued
between 1992 and 2000 were considered for the review.
The type of IFE systems considered for review were those that
contain video monitors (cathode ray tubes or liquid crystal displays;
either hanging above the aisle or mounted on individual seat backs or
seat trays), or complex circuitry (i.e., power supplies, electronic
distribution boxes, extensive wire routing, relatively high power
consumption, multiple layers of circuit protection, etc.). In addition,
in-seat power supply systems that provide power to more than 20 percent
of the total passenger seats were also considered for the review. The
types of IFE systems not considered for review include systems that
provide only audio signals to each passenger seat, ordinary in-flight
telephone systems (e.g., one telephone handset per group of seats or
bulkhead-mounted telephones), systems that only have a video monitor on
the forward bulkhead(s) (or a projection system) to provide passengers
with basic airplane and flight information, and in-seat power supply
systems that provide power to less than 20 percent of the total
passenger seats.
Items considered during the review include the following:
[sbull] Can the electrical bus(es) supplying power to the IFE
system be deenergized when necessary without removing power from
systems that may be required for continued safe flight and landing?
[sbull] Can IFE system power be removed when required without
pulling IFE system circuit breakers (i.e., is there a switch (dedicated
to the IFE system or a combination of loads) located in the flight deck
or cabin that can be used to remove IFE power?)?
[sbull] If the IFE system requires changes to flight crew
procedures, has the airplane flight manual (AFM) been properly amended?
[sbull] If the IFE system requires changes to cabin crew
procedures, have they been properly amended?
[sbull] Does the IFE system require periodic or special
maintenance?
In all, approximately 180 IFE systems approved by STC were reviewed
by the
[[Page 1526]]
FAA. The review results indicate that potential unsafe conditions exist
on some IFE systems installed on various transport category airplanes.
These conditions can be summarized as:
[sbull] Electrical bus(es) supplying power to the IFE system cannot
be deenergized when necessary without removing power from systems that
may be required for continued safe flight and landing.
[sbull] Power cannot be removed from the IFE system when required
without pulling IFE system circuit breakers (i.e., there is no switch
dedicated to the IFE system or combination of systems for the purpose
of removing power).
[sbull] Installation of the IFE system has affected crew (flight
crew and/or cabin crew) procedures, but the procedures have not been
properly revised.
FAA's Determination
As part of its review of IFE systems, the FAA has determined that
an unsafe condition exists on Boeing Model 767-300 series airplanes
modified by STC ST01869AT-D. The passenger entertainment system (PES)
on these airplanes is connected to an electrical bus that cannot be
deactivated without also removing power from airplane systems necessary
for safe flight and landing. There is no other means to remove power
from the PES. Additionally, the airplane manufacturer's published
flight crew and cabin crew emergency procedures do not advise the
flight crew and cabin crew that power cannot be removed from the PES.
This condition, if not corrected, could result in inability to remove
power from the PES during a non-normal or emergency situation, and
consequent inability to control smoke or fumes in the airplane flight
deck or cabin.
Explanation of Relevant Service Information
The FAA has reviewed and approved TIMCO Service Bulletin TSB-767-
23-005, Revision J, dated August 29, 2001; as revised by TIMCO
Engineering Change Orders TSB-767-23-005, Revision J, K1, dated
September 10, 2001; K2, dated September 18, 2001; and K3, dated
September 28, 2001. That service bulletin describes procedures for
modifying the PES by installing two new relays and additional wiring so
that the power switch located in the flight compartment can be used to
remove power completely from the PES. The service documents also
describe procedures for installing a switch guard on the power switch
for the PES. Accomplishment of the actions specified in the service
bulletin is intended to adequately address the identified unsafe
condition.
The FAA also has reviewed and approved TIMCO Airplane Flight Manual
Supplement for Boeing B767-300, TIM-AFM-01034, Revision A, dated
October 12, 2001, which revises the procedures under the heading
``Electrical Smoke or Fire'' in the ``Emergency Procedures'' section of
the AFM to provide instructions for the cabin crew to remove power from
the PES in an emergency.
Explanation of Requirements of the Rule
Since an unsafe condition has been identified that is likely to
exist or develop on other airplanes of the same type design that may be
registered in the United States at some time in the future, this AD is
being issued to ensure that the airplane crew is able to remove
electrical power from the PES when necessary and is advised of
appropriate procedures for such action. Inability to remove power from
the PES during a non-normal or emergency situation could result in
inability to control smoke or fumes in the airplane flight deck or
cabin. This AD requires accomplishment of the actions specified in the
service bulletin described previously. This AD also would require
revising procedures to be followed in the event of smoke or fire in the
airplane, as contained under the heading ``Electrical Smoke or Fire''
in the ``Emergency Procedures'' section of the AFM. Accomplishment of
these actions is intended to adequately address the identified unsafe
condition.
In developing an appropriate compliance time for this action, the
FAA considered not only the degree of urgency associated with
addressing the subject unsafe condition, but the amount of time
necessary to accomplish the proposed actions, and the practical aspect
of accomplishing the proposed actions within an interval of time that
parallels normal scheduled maintenance for the affected operators. In
consideration of these factors, the FAA has determined that 18 months
after the effective date of this AD represents an appropriate interval
of time allowable wherein an acceptable level of safety can be
maintained.
Other Relevant Rulemaking
The FAA has previously issued several ADs that address unsafe
conditions and require corrective actions similar to those that will be
required by this AD. These other ADs, and the airplane models and STCs
to which they apply, are as follows:

Cost Impact
None of the airplanes affected by this action are on the U.S.
Register. All airplanes included in the applicability of this rule
currently are operated by non-U.S. operators under foreign registry;
therefore, they are not directly affected by this AD action. However,
the FAA considers that this rule is necessary to ensure that the unsafe
condition is addressed in the event that any of these subject airplanes
are imported and placed on the U.S. Register in the future.
Should an affected airplane be imported and placed on the U.S.
Register in the future, it would require approximately 17 work hours to
accomplish the required actions, at an average labor rate of $60 per
work hour. Based on these figures, the cost impact of this AD would be
$1,020 per airplane.
Determination of Rule's Effective Date
Since this AD action does not affect any airplane that is currently
on the U.S. register, it has no adverse economic impact and imposes no
additional burden on any person. Therefore, prior notice and public
procedures hereon are unnecessary and the amendment may be made
effective in less than 30 days after publication in the Federal
Register.
Comments Invited
Although this action is in the form of a final rule and was not
preceded by notice and opportunity for public comment, comments are
invited on this rule. Interested persons are invited to comment on this
rule by submitting such written data, views, or arguments as they may
desire. Communications shall identify the Rules Docket number and be
submitted in triplicate to the address specified under the caption
ADDRESSES. All communications received on or before the closing date
for comments will be considered, and this rule may be amended in light
of the comments received. Factual information that supports the
commenter's ideas and suggestions is extremely helpful in evaluating
the effectiveness of the AD action and determining whether additional
rulemaking action would be needed.
Submit comments using the following format:
[sbull] Organize comments issue-by-issue. For example, discuss a
request to change the compliance time and a request to change the
service bulletin reference as two separate issues.
[sbull] For each issue, state what specific change to the AD is
being requested.
[sbull] Include justification (e.g., reasons or data) for each
request.
Comments are specifically invited on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify the rule. All comments submitted will be
available, both before and after the closing date for comments, in the
Rules Docket for examination by interested persons. A report that
summarizes each FAA-public contact concerned with the substance of this
AD will be filed in the Rules Docket.
Commenters wishing the FAA to acknowledge receipt of their comments
submitted in response to this rule must submit a self-addressed,
stamped postcard on which the following statement is made: ``Comments
to Docket Number 2002-NM-56-AD.'' The postcard will be date stamped and
returned to the commenter.
Regulatory Impact
The regulations adopted herein 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. Therefore, it
is determined that this final rule does not have federalism
implications under Executive Order 13132.
For the reasons discussed above, I certify that this action (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. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption
ADDRESSES.
