AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule; request for

comments.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that is

applicable to certain Bombardier Model

CL–600–2B16 series airplanes. This

action requires disabling the remote

fuel/defuel panel in the cockpit. This

action also provides for an optional

modification of the remote fuel/defuel

panel, which would terminate the

requirement to disable the panel. This

amendment is prompted by reports of

in-flight failure of the panel that

resulted when a circuit breaker on a

battery bus opened due to insufficient

current flow capacity. The actions

specified in this AD are intended to

prevent the circuit breakers from

opening during flight, which could

result in irreversible loss of engine

indicating and fuel quantity systems in

the cockpit.

DATES: Effective December 23, 1997.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of December

23, 1997.

Comments for inclusion in the Rules

Docket must be received on or before

January 7, 1998.

SUPPLEMENTARY INFORMATION: The FAA

has received reports of three in-flight

occurrences of loss of all engine

indicating and fuel quantity systems in

the cockpit on certain Bombardier

Model CL–600–2B16 series airplanes. In

each case, the internal fuel/defuel panel

had been left in the ‘‘ON’’ position for

an extended period of time. When the

panel was switched off, all engine and

fuel quantity indications were lost;

subsequent attempts to cycle the panel

power back on were unsuccessful.

Investigation revealed an opened circuit

breaker. It was determined that, if power

to the remote fuel/defuel panel is left on

for up to approximately one hour, the

controlling circuit breaker on the battery

bus will have insufficient capacity to

hold the current flow and, as a result,

may open during flight. This condition,

if not corrected, could result in

irreversible loss of engine indicating

and fuel quantity systems in the cockpit.

Explanation of Relevant Service

Information

Bombardier has issued Service

Bulletin SB TUS–28–20–02–1, dated

November 13, 1997, which describes

procedures for disabling the remote

fuel/defuel panel in the cockpit.

Bombardier also has issued Service

Bulletin SB TUS–28–20–02, dated

November 13, 1997, which describes

procedures for modifying the remote

fuel/defuel panel; accomplishment of

this modification eliminates the need to

disable the panel. The modification

involves replacing certain circuit

breakers for the fuel/defuel power and

fuel quantity displays with new circuit

breakers, and adding three 4-pole relays

to allow switching of fuel quantity when

the internal fuel panel is selected.

U.S. Type Certification of the Airplane

This airplane model is manufactured

in Canada and is type certificated for

operation in the United States under the

provisions of section 21.29 of the

Federal Aviation Regulations (14 CFR

21.29) and the applicable bilateral

airworthiness agreement.
64520 Federal Register / Vol. 62, No. 235 / Monday, December 8, 1997 / Rules and Regulations

Explanation of Requirements of Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other airplanes of the same

type design registered in the United

States, this AD is being issued to

prevent loss of engine indicating and

fuel quantity systems in the cockpit in

the event a circuit breaker opens during

flight. This AD requires disabling the

remote fuel/defuel panel in the cockpit.

This AD also provides for an optional

modification of this panel, which would

terminate the requirement to disable the

panel. The actions are required to be

accomplished in accordance with the

service bulletins described previously.

Determination of Rule’s Effective Date

Since a situation exists that requires

the immediate adoption of this

regulation, it is found that notice and

opportunity for prior public comment

hereon are impracticable, and that good

cause exists for making this amendment

effective in less than 30 days.

Comments Invited

Although this action is in the form of

a final rule that involves requirements

affecting flight safety and, thus, was not

preceded by notice and an 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.

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 97–NM–286–AD.’’ The

postcard will be date stamped and

returned to the commenter.

Regulatory Impact

The regulations adopted herein will

not have substantial direct effects 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, in

accordance with Executive Order 12612,

it is determined that this final rule does

not have sufficient federalism

implications to warrant the preparation

of a Federalism Assessment.

The FAA has determined that this

regulation is an emergency regulation

that must be issued immediately to

correct an unsafe condition in aircraft,

and that it is not a ‘‘significant

regulatory action’’ under Executive

Order 12866. It has been determined

further that this action involves an

emergency regulation under DOT

Regulatory Policies and Procedures (44

FR 11034, February 26, 1979). If it is

determined that this emergency

regulation otherwise would be

significant under DOT Regulatory

Policies and Procedures, a final

regulatory evaluation will be prepared

and placed in the Rules Docket. A copy

of it, if filed, may be obtained from the

Rules Docket at the location provided

under the caption ADDRESSES.

ACTION: Final rule; delay of effective

date.

SUMMARY: This action delays the

effective date for the establishment of

Federal Airway 607 (V–607) between

Mendocino, CA, and Arcata, CA, until

further notice. The FAA is taking this

action due to a procedural change

requiring the addition of an intersection

on V–607. The addition of the

intersection necessitates additional

flight inspection.

DATES: The effective date of 0901 UTC,

January 1, 1998, is delayed until further

notice.

SUPPLEMENTARY INFORMATION:

Airspace Docket No. 97–AWP–17,

published in the Federal Register on

October 27, 1997, (62 FR 55502),

established V–607 between Mendocino,

CA, and Arcata, CA. A need to establish

an intersection at the dogleg of the

Arcata 153° radial and the Mendocino

346° radial requires additional flight

inspection and delays the effective date

of V–607 until further notice.

The FAA has determined that this

regulation only involves an established

body of technical regulations for which

frequent and routine amendments are

necessary to keep them operationally

current. Therefore, this regulation (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)

does not warrant preparation of a

Regulatory Evaluation as the anticipated

impact is so minimal. Since this is a

routine matter that will only affect air

traffic procedures and air navigation, it

is certified that this rule will not have

a significant economic impact on a

substantial number of small entities

under the criteria of the Regulatory

Flexibility Act.
