44598 Federal Register / Vol. 62, No. 163 / Friday, August 22, 1997 / Proposed Rules

Accomplishment of the replacement

would be in accordance with the service

information referenced in the ‘‘Relevant

Service Information’’ section of this

document.

Cost Impact

The FAA estimates that 1,700

airplanes in the U.S. registry would be

affected by the proposed AD, that it

would take approximately 8 workhours

per airplane to accomplish the proposed

replacement, and that the average labor

rate is approximately $60 an hour. Parts

cost approximately $210 per airplane.

Based on these figures, the total cost

impact of the proposed AD on U.S.

operators is estimated to be $1,173,000,

or $690 per airplane.

Piper has informed the FAA that parts

have been distributed to equip 1

affected airplane. Presuming that this

set of parts is installed on an affected

airplane, the cost impact of the

proposed AD would be reduced by

$690, from $1,173,000 to $1,172,310.

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 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) 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 has been placed in the Rules

Docket. A copy of it may be obtained by

contacting the Rules Docket at the

[Airspace Docket No. 94–AWA–1]

Proposed Modification of the Phoenix

Class B Airspace Area; Arizona

AGENCY: Federal Aviation

Administration (FAA), DOT.

ACTION: Supplemental notice of

proposed rulemaking (SNPRM).

SUMMARY: On February 4, 1997, the FAA

published a Notice of Proposed

Rulemaking (NPRM) which proposed to

modify the Phoenix (PHX), AZ, Class B

airspace area. Specifically, that action

proposed to: Reconfigure several area

boundaries; create new areas; and raise

and/or lower the floors of several of the

existing areas. In the NPRM, several

subareas of the PHX Class B airspace

area were inadvertently plotted and

described using incorrect bearings from

the Phoenix Very High Frequency

Omnidirectional Range/Tactical Air

Navigation (VORTAC). This document

corrects that error and amends the

proposed legal description of the PHX

Class B airspace area by changing the

incorrect bearings to reflect the actual

intentions of the FAA.

DATES: Comments must be received on

or before September 22, 1997.

ADDRESSES: Send comments on the

proposal in triplicate to the Federal

of Advisory Circular No. 11–2A, Notice

of Proposed Rulemaking Distribution

System, which describes the application

procedure.

Background

On February 4, 1997, the FAA

proposed to modify the PHX Class B

airspace area (62 FR 5188). The NPRM

proposed to reconfigure several area

boundaries; create new areas; and raise

and/or lower the floors of several of the

existing areas. On April 2, 1997, the

FAA reopened the comment period (62

FR 15635) at the request of several user

organizations as additional time was

necessary to fully analyze the proposal

and make comments. The comment

period closed on May 2, 1997.

The FAA has subsequently discovered

that several subareas of the PHX Class

B airspace area were inadvertently

plotted and described using incorrect

bearings from the Phoenix VORTAC.

On aeronautical charts, bearings to or

from a point are labeled relative to

magnetic north. In airspace legal

descriptions, however, the true north

equivalent of each bearing is published.

In the Phoenix, AZ, area, the variance

between magnetic north and true north

is approximately 12°; therefore, to

convert a bearing from magnetic to true,

one must add 12°.

With regard to subareas D, H, I, J, and

K of the proposed modified PHX Class

B airspace area, bearings intended as

magnetic were erroneously plotted and

published as true; no conversions were

made. This error resulted in bearings,

and geographical coordinates derived

therefrom, being plotted 12°

counterclockwise, relative to the

Phoenix VORTAC, from their intended

positions.

The purpose of this document is to

correct the proposed legal description of

the PHX Class B airspace area to reflect

the actual intentions of the FAA. Only

those subareas of the PHX Class B

airspace area affected by the error are

addressed in this document.

The coordinates for this airspace

docket are based on North American

Datum 83. Class B airspace areas are

published in paragraph 3000 of FAA

Order 7400.9D dated September 4, 1996,

and effective September 16, 1996, which

is incorporated by reference in 14 CFR

part 71.1. The Class B airspace area

listed in this document would be

published subsequently in the Order.

The Proposal

On February 4, 1997, the FAA

proposed to modify the PHX Class B

airspace area. This document proposes

to alter the February 4, 1997, proposal

by amending the legal description of

certain subareas of the PHX Class B

airspace area to reflect the actual

intentions of the FAA. Specifically, this

action proposes to alter the February 4,

1997, proposal by changing the bearings

from the Phoenix VORTAC which are

used to describe subareas D, H, I, J, and

K.

This proposal would change each

affected bearing by adding 12° to the

previously published bearing; this

reflects the conversion factor from

magnetic to true which was previously

omitted. The result of adding 12° to

each affected bearing would be to shift

subareas I, J, K, and the eastern portion

of H, 12° clockwise relative to the PHX

VORTAC.

The practical effects of this change

would be to (1) eliminate approximately

23 square miles of airspace north of

PHX, in the vicinity of Sky Ranch

Carefree Airport, from the previous

proposal to modify the PHX Class B

airspace area; and (2) to add to the

previous proposal approximately 23

square miles of airspace south of PHX

in the area southwest of Bapchule, AZ.

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 proposed rule,

when promulgated, will not have a

significant economic impact on a

substantial number of small entities

under the criteria of the Regulatory

Flexibility Act.
