Applicability: Model F28 Mark 0100 series

airplanes; equipped with Menasco Aerospace

Elevator Booster Control Unit (BCU) having

part number (P/N) 23400–3 or P/N 23400–5

with serial numbers MC–001 through MC–

288 inclusive; 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 (e) 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 backlash in the elevator

controls and reduced elevator control

authority in the manual mode, accomplish

the following:

(a) Within 500 flight cycles or 60 days after

the effective date of this AD, whichever

occurs first, perform an operational check to

detect backlash in the elevator mechanical

control system, in accordance with Part 1 of

the Accomplishment Instructions of Fokker

Service Bulletin SBF100–27–052, Revision 1,

dated March 29, 1994. If no backlash is

detected, repeat the check thereafter at

intervals not to exceed 500 flight cycles or 60

days, whichever occurs first.

(b) If any backlash of the elevator

mechanical control system is detected during

any operational check required by paragraph

(a) of this AD, prior to further flight, perform

an inspection to determine whether the

backlash remover lever and pistons are in the

proper position, in accordance with Part 2

(paragraph I.) of Fokker Service Bulletin

SBF100–27–052, Revision 1, dated March 29,

1994.

(2) If the backlash remover lever and

pistons are not in the proper position: Prior

to further flight, perform an inspection to

determine whether the elevator booster

control unit (BCU) bolts, having part

numbers (P/N) NAS6204C22D and P/N

NAS6204C13D, rotate and slide freely; and to

detect corrosion on the bolts of the backlash

remover lever mechanism; in accordance

with Part 2 (paragraph J.) of the

Accomplishment Instructions of Fokker

Service Bulletin SBF100–27–052, Revision 1,

dated March 29, 1994.

(i) If no anomaly is detected, prior to

further flight, perform appropriate troubleshooting procedures in accordance with the

Airplane Maintenance Manual.

(ii) Except as provided by paragraph

(b)(2)(iii) of this AD, if any anomaly is

detected, prior to further flight, replace the

elevator BCU or bolts, as applicable, with

serviceable parts, in accordance with the

service bulletin.

(iii) If any anomaly is detected,

replacement of the elevator BCU or the bolt

having P/N NAS6204C22D, as applicable,

may be deferred for a period of 10 days,

provided that the three conditions specified

below are met:

(A) The bolt having P/N NAS6204C22D

can be freed so that it rotates and slides

freely; and

(B) That bolt is lubricated subsequent to

the inspection; and

(C) An operational check, as specified in

paragraph (a) of this AD, is accomplished

subsequent to lubrication and is successful.

Note 2: The deferral provision of paragraph

(b)(2)(iii) of this AD does not apply to the

bolt having P/N NAS6204C13D. Replacement

of that part-numbered bolt, when necessary,

cannot be deferred.

(c) Terminating action for the repetitive

check and inspection requirements of this

AD consists of the accomplishment of the

actions specified in either paragraph (c)(1) or

(c)(2) of this AD:

SUPPLEMENTARY INFORMATION:

Request for Comments on the Rule

Although this action is in the form of

a final rule, and was not preceded by

notice and public procedure, comments

are invited on the rule. When the

comment period ends, the FAA will use

the comments submitted, together with

other available information, to review

the regulation. If the FAA receives no

adverse comments in response to this

action, this rule will become effective

on the date specified in the DATES

section. After the review, if the FAA

finds that further changes are

appropriate, it will initiate rulemaking

proceedings to amend the regulation.

Comments that provide the factual

basis supporting the views and

suggestions presented are particularly

helpful in evaluating the effects of the

rule, and in determining whether

additional rulemaking is required.

Comments are specifically invited on

the overall regulatory, aeronautical,

economic, environmental, and energyrelated aspects of the rule which might

suggest the need to modify the rule.

The Rule

This amendment to part 71 of the

Federal Aviation Regulations (14 CFR

part 71) modifies the Class D airspace

areas at Minot AFB and Minot

International Airport, Minot, ND, by

amending the areas’ effective hours to

coincide with the associated control

tower’s hours of operation. Prior to

Airspace Reclassification, an airport

traffic area (ATA) and a control zone

(CZ) existed at these airports. However,

Airspace Reclassification, effective

September 16, 1993, discontinued the

use of the term ‘‘airport traffic area’’ and

‘‘control zone,’’ replacing them with the

designation ‘‘Class D airspace.’’ The

former CZ was continuous, while the

former ATA was contingent upon the

operation of the air traffic control tower.

The consolidation of the ATA and CZ

into a single Class D Airspace

designation makes it necessary to

modify the effective hours of the Class

D airspace to coincide with the control

tower’s hours of operation. The

intended effect of this action is to clarify

when two-way radio communication

with these air traffic control towers is

required.

The coordinates for this airspace

docket are based on North American

Datum 83. Class D airspace designations

are published in Paragraph 5000 of FAA

Order 7400.9D dated September 4, 1996,

and effective September 16, 1996, which

is incorporated by reference in 14 CFR

71.1. The Class D airspace designations

listed in this document will be

published subsequently in the Order.

Under the circumstances presented, the

FAA concludes that there is an

immediate need to modify these Class D

airspace areas in order to promote the

safe and efficient handling of air traffic

in these areas.

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. It, therefore—(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.
