within 12 months after the effective date of

this AD, whichever occurs first.

(b) If no crack is detected during any

inspection required by paragraph (a) of this

AD, repeat the inspection thereafter at

intervals not to exceed 4,000 flight cycles.

(c) If any crack is detected during any

inspection required by this AD, prior to

further flight, accomplish either paragraph

Airworthiness Directives; Saab Model

SAAB 2000 Series Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to certain Saab Model SAAB

2000 series airplanes, that requires a

visual inspection to determine if rudder

disconnection has occurred, and

replacement of the disconnect unit with

a new disconnect unit, if necessary.

This amendment is prompted by reports

that, due to the existing design, the

disconnect unit of the rudder

disconnect system inadvertently opened

on some airplanes. The actions specified

by this AD are intended to prevent the

disconnect unit from opening

inadvertently, which could lead to

inadequate rudder control, if the engine

fails during take-off or go-around and if

the airplane is at low speed.

DATES: Effective March 31, 1997.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of March 31,

1997.

ADDRESSES: The service information

referenced in this AD may be obtained

from SAAB Aircraft AB, SAAB Aircraft

Product Support, S–581.88, Linko ̈ping,

Sweden. This information may be

examined at the Federal Aviation

Administration (FAA), Transport

Airplane Directorate, Rules Docket,

Washington; or at the Office of the

Federal Register, 800 North Capitol

Street, NW., suite 700, Washington, DC.

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to

include an airworthiness directive (AD)

that is applicable to certain Saab Model

SAAB 2000 series airplanes was

published in the Federal Register on

December 12, 1996 (61 FR 65369). That

action proposed to require a visual

inspection to determine if rudder

disconnection has occurred, and, if so,

the immediate replacement of the

disconnect unit with a new unit.

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. No

comments were submitted in response

to the proposal or the FAA’s

determination of the cost to the public.

Conclusion

The FAA has determined that air

safety and the public interest require the

adoption of the rule as proposed.

Cost Impact

The FAA estimates that 3 Saab Model

SAAB 2000 series airplanes of U.S.

registry will be affected by this AD, that

it will take approximately 7 work hours

per airplane to accomplish the required

actions, and that the average labor rate

is $60 per work hour. Required parts

will be provided by the manufacturer at

no cost to operators. Based on these

figures, the cost impact of the AD on

U.S. operators is estimated to be $1,260,

or $420 per airplane.

The cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of

the requirements of this AD action, and

that no operator would accomplish
8162 Federal Register / Vol. 62, No. 36 / Monday, February 24, 1997 / Rules and Regulations

those actions in the future if this AD

were not adopted.

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.

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.

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

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 the disconnect unit from

opening inadvertently, which could lead to

further flight, replace the disconnect unit

with a new disconnect unit, in accordance

with Saab Service Bulletin 2000–27–021,

Revision 1, dated June 19, 1996. After

replacement, no further action is required by

this AD.

(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,

Standardization Branch, ANM–113, FAA,

Transport Airplane Directorate. Operators

shall submit their requests through an

appropriate FAA Principal Maintenance

Inspector, who may add comments and then

send it to the Manager, Standardization

Branch, ANM–113.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the Standardization Branch,

(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.

(d) The inspection shall be done in

accordance with Saab Alert Service Bulletin

2000–A27–020, dated March 25, 1996. The

replacement shall be done in accordance

with Saab Service Bulletin 2000–27–021,

Airport Name Change; Johnson

County Industrial Airport, Olathe, KS

AGENCY: Federal Aviation

Administration [FAA], DOT.

ACTION: Final rule; amendment.

SUMMARY: This amendment changes the

name of the Johnson County Industrial

Airport, Olathe, KS to New Century

Aircenter, Olathe, KS for the class D and

E5 airspace.

EFFECTIVE DATE: February 24, 1997.

SUPPLEMENTARY INFORMATION:

History

In February 1995, the name of the

Johnson County Industrial Airport,

Olathe, KS was changes to New Century

Aircenter. FAA Order 7400.9D was not

amended to reflect this change. This

docket amends that Order.

The Rule

This amendment to part 71 of the

Federal Aviation Regulations (14 CFR

part 71) amends the name of Johnson

County Industrial Airport to New

Century Aircenter. The FAA has

determined that this regulation only

involves a technical regulations for

which frequent and routine

amendments are necessary to keep them

operationally current. Therefore, it (1) is

not a ‘‘significant regulatory action’’

under Executive Order 12886; (2) is not

a ‘‘significant rule’’ under DOT

Regulatory Policies and Procedures (44

CFR 11034: February 26, 1979); and (3)

does not warrant preparation of a

Regulatory Evaluation as the anticipate

impact is so minimal. Since this is a

routine matter that will only affect an

airport name, it is certified that this

rule, when promulgated, will not have

a significant economic impact on a
