37796 Federal Register / Vol. 63, No. 134 /Tuesday, July 14, 1998 / Proposed Rules

the situation described above. The FAA

has examined the findings of the LFV,

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 require

accomplishment of actions specified in

the service bulletin described

previously.

Cost Impact

The FAA estimates that 3 airplanes of

U.S. registry would be affected by this

proposed AD, and that it would take

approximately 2 work hours per

airplane to accomplish the proposed

replacement, at an average labor rate of

$60 per work hour. Required parts

would be provided by the manufacturer

of the RTU at no cost to operators. Based

on these figures, the cost impact of the

replacement proposed by this AD on

U.S. operators is estimated to be $360,

or $120 per airplane.

The cost impact figure discussed

above is 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 AD were not adopted.

Regulatory Impact

The regulations proposed herein

would 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

proposal would not have sufficient

federalism implications to warrant the

preparation of a Federalism Assessment.

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

The Proposed Amendment

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

Administration proposes to amend part

39 of the Federal Aviation Regulations

(14 CFR part 39) as follows:

PART 39—AIRWORTHINESS

DIRECTIVES

1. The authority citation for part 39

continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding the following new airworthiness

directive:

Saab Aircraft AB: Docket 97–NM–144–AD.

Applicability: Model SAAB 2000 series

airplanes, as listed in Saab Service Bulletin

2000–23–017, dated March 10, 1997;

certificated in any category.

Note 1: This AD applies to each airplane

identified in the preceding applicability

provision, regardless of whether it has been

modified, altered, or repaired in the area

subject to the requirements of this AD. For

airplanes that have been modified, altered, or

repaired so that the performance of the

requirements of this AD is affected, the

owner/operator must request approval for an

alternative method of compliance in

accordance with paragraph (b) of this AD.

The request should include an assessment of

the effect of the modification, alteration, or

repair on the unsafe condition addressed by

this AD; and, if the unsafe condition has not

been eliminated, the request should include

specific proposed actions to address it.

Compliance: Required as indicated, unless

accomplished previously.

To prevent NAV/COM radios from

simultaneously changing tuned frequencies

and transponder codes due to a black screen

failure or ‘‘blanking’’ of a radio tuning unit

(RTU), which could result in loss of

communications capability and air traffic

control data, accomplish the following:

(a) Within 1 year after the effective date of

this AD, replace the existing RTU’s and

associated components with new, improved

parts, in accordance with Saab Service

Bulletin 2000–23–017, dated March 10, 1997.

(b) An alternative method of compliance or

adjustment of the compliance time that

provides an acceptable level of safety may be

used if approved by the Manager,

International Branch, ANM–116, FAA,

Transport Airplane Directorate. Operators

shall submit their request through an

appropriate FAA Principal Maintenance

Inspector, who may add comments and then

send it to the Manager, International Branch,

ANM–116.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the International Branch,

ANM–116.

(c) Special flight permits may be issued in

accordance with sections 21.197 and 21.199

of the Federal Aviation Regulations (14 CFR

21.197 and 21.199) to operate the airplane to

a location where the requirements of this AD

can be accomplished.

Note 3: The subject of this AD is addressed

in Swedish airworthiness directive SAD 1–

109, dated March 12, 1997.

Issued in Renton, Washington, on July 7,

1998.

FOR FURTHER INFORMATION CONTACT:

Patricia W. Silvey, Director, Office of

Standards, Regulations and Variances,

703–235–1910.

SUPPLEMENTARY INFORMATION: On April

9, 1998, MSHA published a proposed

rule in the Federal Register (63 FR

17492) establishing health standards for

underground coal mines that use

equipment powered by diesel engines.

The proposal is designed to reduce

serious health hazards that are

associated with exposure to high

concentrations of diesel particulate

matter (dpm). Dpm is a very small

particle in diesel exhaust. Underground

miners are exposed to far higher

concentrations of this fine particulate

than any other group of workers. The

best available evidence indicates that

exposure to diesel particulate matter

puts miners at excess risk of a variety of

adverse health effects, including lung

cancer.

The National Environmental Policy

Act (NEPA) of 1969 (42 U.S.C. 4321 et.

seq.), requires each Federal agency to

consider the environmental effects of

proposed actions and to prepare an

Environmental Impact Statement on

major actions significantly affecting the

quality of the human environment.

MSHA has reviewed the proposed

standard in accordance with the

requirements of the NEPA, the

regulation of the Council on

Environmental Quality (40 CFR Part

1500), and the Department of Labor’s

NEPA procedures (29 CFR Part 11). As

a result of this review, MSHA has

preliminarily determined that this

proposed standard will have no

significant environmental impact.

Commenters are encouraged to submit

their comments on this determination

on or before August 10, 1998.

Dated: July 8, 1998.

J. Davitt McAteer,

Assistant Secretary for Mine Safety and

Health.
