ACTION: Final rule; request for

comments.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that is

applicable to certain Israel Aircraft

Industries, Ltd., Model 1124 and 1124A

Westwind airplanes. This action

requires a one-time X-ray inspection to

detect missing rivets at the rib-to-spar

connection of the aileron ribs, and

corrective actions, if necessary. This

action is necessary to prevent cracking

of the aileron skin due to missing rivets,

which could result in reduced structural

integrity of the aileron and consequent

reduced controllability of the airplane.

This action is intended to address the

identified unsafe condition.

SUPPLEMENTARY INFORMATION: The Civil

Aviation Administration of Israel

(CAAI), notified the FAA that an unsafe

condition may exist on certain Israel

Aircraft Industries, Ltd., Model 1124

and 1124A Westwind airplanes. The

CAAI advises that rivets in the aileron

structure have been reported missing.

On one airplane, 5 of the 13 aileron ribs

were missing rivets. Investigation

revealed certain rivets may not have

been installed during production. This

condition, if not corrected, could result

in reduced structural integrity of the

aileron and consequent reduced

controllability of the airplane.

Explanation of Relevant Service

Information

The manufacturer has issued Israel

Aircraft Industries 1124 Westwind Alert

Service Bulletin No. 1124–27A–145,

dated March 24, 2000, which describes

procedures for a one-time X-ray

inspection to detect missing rivets at the

rib to spar connection of the aileron

ribs, left and right sides, at work stations

(WS) 158.00 through WS 246.00. The

CAAI classified this alert service

bulletin as mandatory and previously

issued Israeli airworthiness directive

57–00–02–06, dated February 24, 2000,

in order to assure the continued

airworthiness of these airplanes in

Israel.

FAA’s Conclusions

These airplane models are

manufactured in Israel and are 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. Pursuant to this bilateral

airworthiness agreement, the CAAI has

kept the FAA informed of the situation

described above. The FAA has

examined the findings of the CAAI,

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 Rule

Since an unsafe condition has been

identified that is likely to exist or

32014 Federal Register / Vol. 65, No. 99 / Monday, May 22, 2000 / Rules and Regulations

develop on other airplanes of the same

type design registered in the United

States, this AD is being issued to

prevent cracking of the aileron skin due

to missing rivets, which could result in

reduced structural integrity of the

aileron and consequent reduced

controllability of the airplane. This AD

requires a one-time X-ray inspection to

detect missing rivets at the rib to spar

connection of the aileron ribs, and

corrective actions, if necessary. The

actions are required to be accomplished

in accordance with the alert service

bulletin described previously, except as

discussed below.

Differences Between AD and Alert

Service Bulletin

Operators should note that, although

the alert service bulletin specifies that

the Customer Support Group at Galaxy

Aerospace Company may be contacted

for disposition of certain conditions,

this amendment would require the

repair of those conditions to be

accomplished in accordance with a

method approved by either the FAA or

the CAAI (or its delegated agent). In

light of the type of repair that would be

required to address the identified unsafe

condition, and in consonance with

existing bilateral airworthiness

agreements, the FAA has determined

that, for this AD, a repair approved by

either the FAA or the CAAI would be

acceptable for compliance with this AD.

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.

Submit comments using the following

format:

• 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.

• For each issue, state what specific

change to the AD is being requested.

• 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 2000–NM–42–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.

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.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) for

Eurocopter France Model AS350B, BA,

B1, B2, B3, D, and AS355E, F, F1, F2,

and N helicopters that requires

replacing certain circuit breakers. This

amendment is prompted by the

discovery of the loss of electrical

continuity between the terminals of an

installed circuit breaker. The actions

specified by this AD are intended to

prevent loss of electrical power to the

emergency flotation gear or other

optional installations and subsequent

loss of the helicopter emergency

flotation capability.

DATES: Effective June 26, 2000.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of June 26,

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to

include an AD for Eurocopter France

Model AS350B, BA, B1, B2, B3, D, and

AS355E, F, F1, F2, and N helicopters

was published in the Federal Register

on February 23, 2000 (65 FR 8894). That

action proposed to require inspecting

Crouzet single-pole circuit breakers for

proper operation; replacing any Crouzet

single-pole circuit breaker that is not

operating properly with an airworthy

circuit breaker; and replacing all

Crouzet single-pole circuit breakers with

airworthy circuit breakers on or before

July 1, 2000.

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. No

comments were received on the

proposal or the FAA’s determination of

the cost to the public. The FAA has

determined that air safety and the

public interest require the adoption of

the rule as proposed.

The FAA estimates that 150

helicopters of U.S. registry will be

affected by this AD, that it will take

approximately 0.25 work hour per

helicopter to replace the circuit

breakers, and that the average labor rate

is $60 per work hour. Required parts

will cost approximately $23 per

helicopter. Based on these figures, the

total cost impact of the AD on U.S.

operators is estimated to be $5,700,

assuming the replacement of 150 circuit

breakers.

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.
