1. In this document, the Wireless Telecommunications Bureau of the
Federal Communications Commission we address pending issues regarding
certain Aviation Service ground station equipment. Primarily, we
consider a petition for rulemaking filed by the National
Telecommunications and Information Administration (NTIA), and supported
by the Federal Aviation Administration (FAA), requesting that the
Commission amend part 87 of the Commission's Rules to allow use of the
frequency 1090 MHz by aeronautical mobility mobile stations for airport
surface detection equipment (ASDE-X), commonly referred to as vehicle
``squitters.'' It also seeks comment on a proposal by Potomac Aviation
Technology Corporation (PATC) to permit remote monitoring of certain
automated ground stations during installation and maintenance, without
a licensed technician present. It also proposes to codify the terms of
a waiver granted to Aviation Data Systems (Aust) Pty Ltd. (ADS) to
permit licensing and equipment certification of devices to test
aircraft data link systems.

C. Paperwork Reduction Act
8. This NPRM does not contain any proposed information
collection(s) subject to the Paperwork Reduction Act of 1995, Public
Law 104-13. In addition, it does not contain any new or modified
``information collection burden for small business concerns with fewer
than 25 employees,'' pursuant to the Small Business Paperwork Relief
Act of 2002, Public Law 107-198, see 44 U.S.C. 3506(c)(4).
II. Initial Regulatory Flexibility Analysis
9. As required by the Regulatory Flexibility Act (RFA), the
Commission has prepared this Initial Regulatory Flexibility Analysis
(IRFA) of the possible significant economic impact on small entities of
the policies and rules proposed in the NPRM. Written public comments
are requested on this IRFA. Comments must be identified as responses to
the IRFA and must be filed by the deadlines for comments on the NPRM as
provided in paragraph 24 of the item, supra. The Commission will send a
copy of the NPRM, including this IRFA, to the Chief Counsel for
Advocacy of the Small Business Administration. In addition, the NPRM
and IRFA (or summaries thereof) will be published in the Federal
Register.
A. Need for, and Objectives of, the Proposed Rules
10. The proposed rules in the NPRM are intended to address new
requirements for aviation radio equipment in a manner that will further
aviation safety; and to amend the aviation rules related to the
installation and maintenance of aviation equipment and the testing of
aviation data link systems. In the NPRM, we request comment
specifically on whether we should: (a) Permit the operation and
licensing of vehicle squitters on frequency 1090 MHz to promote
aviation safety, and (b) remove the requirement that a holder of a
General Radiotelephone Operator Licensees (GROL) be physically present
during installation and maintenance of certain land-based Aviation
Radio Service stations, and (c) permit a new emission type for
radionavigation land test equipment (RLT).
B. Legal Basis
11. Authority for issuance of this item is contained in Sec. Sec.
4(i), 303(r), and 403 of the Communications Act of 1934, as amended, 47
U.S.C. 154(i), 303(r) and 403.
C. Description and Estimate of the Number of Small Entities to Which
the Proposed Rules Will Apply
12. The RFA directs agencies to provide a description of and, where
feasible, an estimate of the number of small entities that may be
affected by the proposed rules, if adopted. The RFA generally defines
the term ``small entity'' as having the same meaning as the terms
``small business,'' ``small organization,'' and ``small governmental
jurisdiction.'' In addition, the term ``small business'' has the same
meaning as the term ``small business concern'' under the Small Business
Act. A small business concern is one that: (1) Is independently owned
and operated; (2) is not dominant in its field of operation; and (3)
satisfies any additional criteria established by the SBA. Pursuant to 5
U.S.C. 601(3), the statutory definition of a small business applies
``unless an agency after consultation with the Office of Advocacy of
the SBA, and after opportunity for public comment, establishes one or
more definitions of such term which are appropriate to the activities
of the agency and publishes such definition(s) in the Federal
Register.''
13. Small businesses in the aviation radio services use very high
frequency (VHF), medium frequency (MF), or high frequency (HF) radio,
radar, aircraft radio, and/or any type of emergency locator transmitter
(ELT). The Commission has not developed a definition of small entities
specifically applicable to these small businesses. For purposes of this
IRFA, therefore, the applicable definition of small entity is the
definition under the SBA rules applicable to wireless service
providers. The SBA has developed a small business size standard for
wireless firms within the two broad economic census categories of
``Paging'' and ``Cellular and Other Wireless Telecommunications.''
Under both categories, the SBA deems a wireless business to be small if
it has 1,500 or fewer employees. For the census category of Paging,
Census Bureau data for 2002 show that there were 807 firms in this
category that operated for the entire year. Of this total, 804 firms
had employment of 999 or fewer employees, and three firms had
employment of 1,000 employees or more. Thus, under this category and
associated small business size standard, the majority of firms can be
considered small. For the census category of Cellular and Other
Wireless Telecommunications, Census Bureau data for 2002 show that
there were 1,397 firms in this category that operated for the entire
year. Of this total, 1,378 firms had employment of 999 or fewer
employees, and 19 firms had employment of 1,000 employees or more.
Thus, under this second category and size standard, the majority of
firms can, again, be considered small.
14. Some of the rules proposed herein may also affect small
businesses that manufacture aviation radio equipment. The Commission
has not developed a definition of small entities applicable to aviation
radio equipment manufacturers. Therefore, the applicable definition is
that for Radio and Television Broadcasting and Wireless Communications
Equipment Manufacturers. The Census Bureau defines this category as
follows: ``This industry comprises establishments primarily engaged in
manufacturing radio and television broadcast and wireless
communications equipment. Examples of products made by these
establishments are: Transmitting and receiving antennas, cable
television equipment, GPS equipment, pagers, cellular phones, mobile
communications equipment, and radio and television studio and
broadcasting equipment.'' The SBA has developed a small business size
standard for Radio
[[Page 22354]]
and Television Broadcasting and Wireless Communications Equipment
Manufacturing, which is: All such firms having 750 or fewer employees.
According to Census Bureau data for 2002, there were a total of 1,041
establishments in this category that operated for the entire year. Of
this total, 1,010 had employment of under 500, and an additional 13 had
employment of 500 to 999. Thus, under this size standard, the majority
of firms can be considered small.
D. Description of Projected Reporting, Recordkeeping, and Other
Compliance Requirements for Small Entities
15. The rule changes under consideration in the NPRM would require
manufacturers to meet certain criteria and potential licensees would be
required to operate the equipment as prescribed in the Rules, including
prior coordination with the FAA. We believe the other proposed rules
would have no significant effect on the compliance burdens of
regulatees. We invite comment on our tentative conclusion that the
possible rule changes will not have a negative impact on small
entities, or for that matter any entities, and do not impose new
compliance costs on any entity. To the extent that commenters believe
that any of the above possible rule changes would impose a new
reporting, recordkeeping, or compliance burden on small entities, we
ask that they describe the nature of that burden in some detail and, if
possible, quantify the costs to small entities.
E. Steps Taken To Minimize Significant Economic Impact on Small
Entities and Significant Alternatives Considered
16. The RFA requires an agency to describe any significant
alternatives that it has considered in reaching its proposed approach,
which may include the following four alternatives: (1) The
establishment of differing compliance or reporting requirements or
timetables that take into account the resources available to small
entities; (2) the clarification, consolidation, or simplification of
compliance or reporting requirements under the rule for small entities;
(3) the use of performance, rather than design, standards; and (4) an
exemption from coverage of the rule, or any part thereof, for small
entities.
17. This NPRM proposes to permit new equipment to be utilized by
ground vehicles at airports; to remove the requirement that the holder
of a General Radiotelephone Operator Licensees (GROL) be physically
present during an installation or maintenance of certain land-based
Aviation Radio Service station; and to permit a new emission type for
radionavigation land test equipment (RLT). To the extent commenters
believe that other of the discussed rule changes would impose a
compliance burden on small entities, we ask that they address whether
any of the above approaches to reduce that burden is appropriate.
18. We hereby invite interested parties to address any or all of
these regulatory alternatives and to suggest additional alternatives to
minimize any significant economic impact on small entities. Any
significant alternative presented in the comments will be considered.
F. Federal Rules That May Duplicate, Overlap, or Conflict With the
Proposed Rules
19. None.
III. Ordering Clauses
20. Pursuant to sections 4(i), 4(j), and 303(r) of the
Communications Act of 1934, as amended, 47 U.S.C. 154(i), 154(j),
303(r), notice is hereby given of the proposed regulatory changes
described in the NPRM, and comment is sought on the proposed regulatory
changes as set forth below.
21. The Commission's Consumer & Governmental Affairs Bureau,
Reference Information Center, SHALL SEND a copy of this NPRM, including
the Initial Regulatory Flexibility Analysis, to the Chief Counsel for
Advocacy of the Small Business Administration.
