eddy current inspection, and that the

average labor rate is $60 per work hour.

Based on these figures, the cost impact

of the proposed AD on U.S. operators is

estimated to be $2,760, 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 proposed AD were not adopted. The

cost impact figures discussed in AD

rulemaking actions represent only the

time necessary to perform the specific

actions actually required by the AD.

These figures typically do not include

incidental costs, such as the time

required to gain access and close up,

planning time, or time necessitated by

other administrative actions.

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.

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes the

adoption of a new airworthiness

directive (AD) that is applicable to all

Fokker Model F27 Mark 100, 200, 300,

400, 500, 600, and 700 series airplanes.

This proposal would require a one-time

Federal Register / Vol. 66, No. 124 / Wednesday, June 27, 2001 / Proposed Rules 34135

inspection for correct installation of the

left- and right-hand fuel differential

pressure (FDP) switches and for correct

connection of the pressure sensing lines

to the switches. It would also require

corrective action, if necessary. This

action is prompted by reports of

incorrect installation of the FDP

switches and the resulting crossconnection of the pressure sensing lines

to those switches. This action is

necessary to ensure that a warning light

goes on when the fuel filter is partially

blocked by ice, so that the blockage of

the fuel filter does not increase, leading

to reduced fuel flow to the engine and

possibly to an engine flame-out. This

action is intended to address the

identified unsafe condition.

DATES: Comments must be received by

July 27, 2001.

ADDRESSES: Submit comments in

triplicate to the Federal Aviation

Administration (FAA), Transport

Airplane Directorate, ANM–114,

Discussion

Fokker has issued an information

sheet indicating that on several

occasions fuel differential pressure

(FDP) switches have been installed

upside down in their mountings and, as

a result, the pressure sensing lines to

those switches have been crossconnected. With this incorrect

installation, the light which warns the

flight crew that the fuel filter is partially

blocked by ice would not light up.

Without this warning, blockage of the

fuel filter could continue, leading to

reduced fuel flow to the engine and

possibly to an engine flame-out. Fokker

has also introduced changes to the F27

Maintenance Manual to emphasize the

correct position of the fuel differential

pressure switch and identification of the

fuel lines to the switch.

Explanation of Relevant Service

Information

Fokker has issued Service Bulletin

F27/28–63, dated November 21, 1999,

which describes procedures for a onetime inspection for correct installation

of the left- and right-hand FDP switches,

correct connection of the pressure

sensing lines to the FDP switches, and

corrective action, if necessary.

U.S. Type Certification of the Airplane

These airplane models are

manufactured in the Netherlands and

are 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.

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 the actions specified

in the service bulletin described

previously.

Cost Impact

The FAA estimates that 44 airplanes

of U.S. registry would be affected by this

proposed AD, that it would take

approximately 1 work hour per airplane

to accomplish the proposed one-time

inspection, and that the average labor

rate is $60 per work hour. Based on

these figures, the cost impact of the

proposed AD on U.S. operators is

estimated to be $2,640, or $60 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 proposed AD were not adopted. The

cost impact figures discussed in AD

rulemaking actions represent only the

time necessary to perform the specific

actions actually required by the AD.

These figures typically do not include

incidental costs, such as the time

required to gain access and close up,

planning time, or time necessitated by

other administrative actions.

Regulatory Impact

The regulations proposed herein

would not have a substantial direct

effect on the States, on the relationship

between the national Government and

34136 Federal Register / Vol. 66, No. 124 / Wednesday, June 27, 2001 / Proposed Rules

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

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:

Fokker Services B.V.: Docket 2001-NM–24-

AD.

Applicability: All Model F27 Mark 100,

200, 300, 400, 500, 600, and 700 series

airplanes, 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 ensure that a warning light goes on

when the fuel filter is partially blocked by

ice, so that the blockage of the fuel filter does

not continue, leading to reduced fuel flow to

the engine and possibly to an engine flameout, accomplish the following:

Inspection

(a) Within 60 days from the effective date

of this AD: Perform a one-time general visual

inspection for correct installation of the leftand right-hand fuel differential pressure

(FDP) switches and for correct connection of

the pressure sensing lines to the FDP

switches, in accordance with the

Accomplishment Instructions of Fokker

Service Bulletin F27/28–63, dated November

21, 1999. If the switches are found to be

installed incorrectly, as specified in the

service bulletin, prior to further flight, reinstall the switches and re-connect the

pressure sensing lines to the switches, in

accordance with the service bulletin.

Note 2: For the purposes of this AD, a

general visual inspection is defined as: ‘‘A

visual examination of an interior or exterior

area, installation, or assembly to detect

obvious damage, failure, or irregularity. This

level of inspection is made under normally

available lighting conditions such as

daylight, hangar lighting, flashlight, or droplight, and may require removal or opening of

access panels or doors. Stands, ladders, or

platforms may be required to gain proximity

to the area being checked.’’

Alternative Methods of Compliance

(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, Transport

Airplane Directorate, FAA. Operators shall

submit their requests through an appropriate

FAA Principal Maintenance Inspector, who

may add comments and then send it to the

Manager, International Branch, ANM–116.

Note 3: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the International Branch,

ANM–116.

Special Flight Permits

(c) Special flight permits may be issued in

accordance with §§ 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.

ACTION: Withdrawal of notices of

proposed rulemaking.

SUMMARY: This document withdraws

two notices of proposed rulemaking,

one relating to corporations filing

consolidated income tax returns and the

other relating to collapsible

corporations. The proposed regulations

were published before the enactment of

the Internal Revenue Code of 1986, do

not reflect changes to the tax law made

after their publication, and will not be

finalized unless reproposed.

DATES: These proposed regulations are

withdrawn June 27, 2001.

FOR FURTHER INFORMATION CONTACT:

Charles M. Whedbee (202) 622–7550

SUPPLEMENTARY INFORMATION:

Background

On July 31, 1984, the IRS issued

proposed regulations (LR–97–79)

relating to corporations filing

consolidated returns (49 FR 30528).

Portions of these proposed consolidated

return regulations were withdrawn by

subsequent notices of proposed

rulemaking (CO–78–90 and REG–

103805–99) published in the Federal

Register on February 4, 1991 (56 FR

4228) and September 26, 2000 (65 FR

57755).

On August 31, 1984, the IRS issued

proposed regulations (LR–107–84)

relating to collapsible corporations (49

FR 34523).

The IRS is withdrawing these

proposed regulations because of

intervening amendments to the Internal

Revenue Code and because these

regulations projects will not be

undertaken in the foreseeable future (or

if undertaken, the regulations will be

reproposed).

Drafting Information

The principal author of this

withdrawal notice is Charles M.

Whedbee of the Office of the Associate

Chief Counsel (Corporate). However,
