would accomplish those actions in the

future if the 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.

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 767–

300 series airplanes modified by STC

SA5765NM or SA5978NM. The IFE

system on these airplanes is connected

to an electrical bus that cannot be

deenergized without also removing

power from airplane systems necessary

for safe flight and landing. Additionally,

the airplane manufacturer’s published

flight crew and cabin crew procedures

do not advise the crewmembers on

removing power from the IFE system.

This condition, if not corrected, could

result in inability to remove power from

the IFE 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 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 removal of the IFE system

installed by STC SA5765NM or

SA5978NM. The action would be

required to be accomplished by a

method approved by the FAA.

Subsequent to the FAA’s review of these

STC’s, the STC holder informed the

FAA that the IFE systems installed by

these STC’s have been removed from all

affected airplanes. However, the FAA

finds it necessary to propose this AD to

ensure that all operators have indeed

removed the IFE systems and to prohibit

future installation of the systems in

other eligible airplanes.

Calculation of Compliance Time

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

13194 Federal Register / Vol. 66, No. 42 / Friday, March 2, 2001 / Proposed Rules

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 Proposed Rulemaking

This proposed action is one of a

number of proposed AD’s on airplanes

modified by STC’s that have been

determined to be subject to similar

unsafe conditions. Other currently

proposed AD’s include the following

airplanes and STC’s:

Cost Impact

As stated previously, the holder of the

STC’s has informed the FAA that the

subject IFE systems have been removed

from all affected airplanes. Therefore,

the FAA expects that there will be no

future cost impact on U.S. operators as

a result of the proposed rule.

However, if an airplane subject to this

AD is identified, the FAA estimates that

removal of the IFE system would take

approximately 12 work hours per

airplane, at an average labor rate of $60

per work hour. Based on these figures,

the cost impact of the proposed AD on

an affected airplane is estimated to be

$720 per airplane.

The cost impact figure discussed

above is based on information that the

subject IFE systems have been removed

from all affected airplanes. The cost

impact figures discussed in most

proposed AD actions are based on

assumptions that no operator has yet

accomplished any of the proposed

requirements, and that no operator

would accomplish those actions in the

future if the 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.
