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. STC’s 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:

• 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?

• 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?]

• If the IFE system requires changes

to flight crew procedures, has the

airplane flight manual (AFM) been

properly amended?

• If the IFE system requires changes

to cabin crew procedures, have they

been properly amended?

• Does the IFE system require

periodic or special maintenance?

In all, approximately 180 IFE systems

approved by STC were reviewed by the

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:

• 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.

• 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).

• 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 737–

700IGW series airplanes modified by

STC’s ST09100AC–D, ST09104AC–D,

ST09105AC–D, or ST09106AC–D.

Currently, multiple circuit breakers in

the flight and avionics compartments

control power to various components of

the passenger entertainment system

(PES) installed by those STC’s. To

remove power from the PES in the event

of an emergency, the flight crew must

locate and open each of the subject

circuit breakers. This condition, if not

corrected, could result in failure to

remove power from the entire PES

system 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

Raytheon Service Bulletin 737IGW–24–

1, dated August 11, 2000. The service

bulletin describes procedures for

modifying the PES by installing a power

switch and a load-shed circuit breaker

as well as associated relays and wiring.

The FAA has also reviewed and

approved Raytheon Flight Manual

Supplement B737–700 IGW, dated

October 16, 2000, which is supplied

with the service bulletin. The Flight

Manual Supplement contains a revision

of the Non-Normal Procedures section

of the FAA-approved AFM to advise the

flight crew on using the power switch

to remove power from the PES in the

event of an emergency related to smoke

or fire. Accomplishment of the actions

specified in the service bulletin,

including the Flight Manual

Supplement, is intended to adequately

address the identified unsafe condition.

Explanation of Requirements of

Proposed Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other products of this same

type design, the proposed AD would

require accomplishment of the actions

specified in the service bulletin

described previously, except as

discussed below.

Differences Between Proposed Rule and

Service Bulletin

Operators should note that the service

bulletin specifies that a Flight Manual

Supplement for the Boeing 737–700IGW

is included with the service bulletin.

However, the service bulletin does not

specify what action operators must take

with regard to this Flight Manual

Supplement. The FAA has determined

that revision of the AFM is necessary to

ensure that the flight crew is aware of

the installation of a power switch for the

PES and that they are advised of

appropriate use of the switch. Therefore,

paragraph (a)(2) of this proposed AD

would require operators to revise the

AFM by inserting the Flight Manual

Supplement supplied with the service

bulletin.

Operators also should note that the

service bulletin specifies that the

actions therein should be accomplished

at the next maintenance opportunity,

but not later than 12 months after

receipt of the service bulletin. 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, the availability of

necessary parts, 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

all 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 Proposed Rulemaking

This proposed action is one of a

number of proposed AD’s on airplanes

modified by STC’s that have been

13212 Federal Register / Vol. 66, No. 42 / Friday, March 2, 2001 / Proposed Rules

determined to be subject to similar

unsafe conditions. Other currently

proposed AD’s include the following

Cost Impact

There are approximately 4 airplanes

of the affected design in the worldwide

fleet. The FAA estimates that 2

airplanes of U.S. registry would be

affected by this proposed AD.

It would take approximately 141 work

hours per airplane to accomplish the

proposed modification, at an average

labor rate of $60 per work hour.

Required parts would cost

approximately $95,968 per airplane.

Based on these figures, the cost impact

of the modification in this proposed AD

on U.S. operators is estimated to be

$208,856, or $104,428 per airplane.

It would take approximately 1 work

hour per airplane to accomplish the

proposed AFM revision, at an average

labor rate of $60 per work hour. Based

on these figures, the cost impact of the

AFM revision in this proposed AD on

U.S. operators is estimated to be $120,

or $60 per airplane.

The cost impact figures discussed

above are based on assumptions that no

operator has yet accomplished any of

the proposed requirements of this AD

action, and that no operator would

accomplish those actions in the future if

this proposed AD were not adopted. The

cost impact figures discussed in AD

rulemaking actions represent only the

time necessary to perform the specific

actions actually required by the AD.

These figures typically do not include

incidental costs, such as the time

required to gain access and close up,

planning time, or time necessitated by

other administrative actions.

Regulatory Impact

The regulations proposed herein

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. Therefore,

it is determined that this proposal

would not have federalism implications

under Executive Order 13132.

For the reasons discussed above, I

certify that this 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) if

promulgated, 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 copy of the draft

regulatory evaluation prepared for this

action is contained in the Rules Docket.

A copy of it may be obtained by
