SUMMARY: This document proposes the

supersedure of an existing airworthiness

directive (AD), applicable to Model CL–

604 variant of Bombardier Model

Canadair CL–600–2B16 series airplanes

modified in accordance with certain

Supplemental Type Certificates that

currently requires that the fuel service

panel maintenance light on the fuel

service panel be disconnected. This

action would require modification of the

wiring of the fuel port flood light (which

is the name given to the fuel service

59384 Federal Register / Vol. 65, No. 194 / Thursday, October 5, 2000 / Proposed Rules

panel maintenance light in the service

bulletin that describes the wiring

modification). This proposal is

prompted by a report indicating that an

electrical spark was noted when the fuel

cap chain contacted the fuel port flood

light housing of the fuel service panel.

The actions specified by the proposed

AD are intended to prevent electrical

sparks from a grounded object from

coming into contact with the fuel port

flood light housing of the fuel service

panel, which could result in a fuel fire

due to the proximity of the fuel service

panel to the fuel port.

Discussion

On January 13, 2000, the FAA issued

AD 2000–01–51, amendment 39–11519,

(65 FR 3379, January 21, 2000)

applicable to CL–604 variant of

Bombardier Model Canadair CL–600–

2B16 series airplanes modified in

accordance with Supplemental Type

Certificate SA8060NM–D, SA8072NM–

D, or SA8086NM–D. That AD required

that the fuel service panel maintenance

light on the fuel service panel be

disconnected. That action was

prompted by a report indicating that an

electrical spark was noted when the fuel

cap chain contacted the maintenance

light housing of the fuel service panel.

The requirements of that AD were

intended to prevent electrical sparks

from a grounded object from coming

into contact with the maintenance light

housing of the fuel service panel, which

could result in a fuel fire due to the

close proximity of the fuel service panel

to the fuel port.

Actions Since Issuance of Previous Rule

In the preamble of AD 2000–01–51,

the FAA indicated that the action

required by that AD was considered

‘‘interim action’’ and that further

rulemaking was being considered. Since

the issuance of that AD, the

manufacturer has advised that it has

developed a modification that will

positively address the unsafe condition.

The FAA has determined that further

rulemaking is indeed necessary; this

proposed AD follows from that

determination.

Explanation of Relevant Service

Information

Bombardier has issued Service

Bulletins TUC–33–30–01–1, dated

February 1, 2000, and TUC–33–30–01–

1, Revision A, dated March 10, 2000,

which describe procedures for

modification of the wiring of the fuel

port flood lights. The modification

involves re-routing the wires in the

flood light assembly, verifying the

proper termination, adding an

additional ground wire to the flood light

assembly, and verifying the bonding of

the fuel port flood light to the airplane

structure. Accomplishment of the

actions specified in the service bulletins

is intended to adequately address the

identified unsafe condition.

FAA’s Conclusions

This airplane model is manufactured

in Canada and is type certificated for

operation in the United States under the

provisions of § 21.29 of the Federal

Aviation Regulations (14 CFR 21.29)

and the applicable bilateral

airworthiness agreement. The FAA has

reviewed all available information and

determined that AD action is necessary

for products of this type design that are

certificated for operation in the United

States.

Explanation of Requirements of

Proposed 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, the proposed AD would

supersede AD 2000–01–51 to require

modification of the wiring of the fuel

port flood lights. The actions would be

required to be accomplished in

accordance with the service bulletins

described previously. The FAA has

determined that long term operational

safety will be better assured by this

modification than by leaving the fuel

port flood lights disconnected. This

Federal Register / Vol. 65, No. 194 / Thursday, October 5, 2000 / Proposed Rules 59385

determination was based in part on the

possibility of human error associated

with possible future reconnection of the

lights.

Cost Impact

There are approximately 22 airplanes

of U.S. registry that would be affected

by this proposed AD.

The modification that is proposed in

this AD action would take

approximately 2 work hours per

airplane to accomplish, at an average

labor rate of $60 per work hour. The

cost of the parts required for each

airplane are minimal. Based on these

figures, the cost impact of the proposed

requirements of this AD on U.S.

operators is estimated to be $2,640, or

$120 per airplane.

The cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of

the current or proposed requirements of

this AD action, and that no operator

would accomplish those actions in the

future if this AD were not adopted.

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

contacting the Rules Docket at the

location provided under the caption
