1. The WT Docket No. 01-289 rulemaking proceeding was established
to ensure that part 87 of the Commission's rules remains up-to-date and
continues to further the Commission's goals of accommodating new
technologies, facilitating the efficient and effective use of the
aeronautical spectrum, avoiding unnecessary regulation, and, above all,
enhancing the safety of flight. The Commission takes the following
significant actions in the Second FNPRM in WT Docket No. 01-289: (i)
Invites further comment on technical standards and regulatory
provisions for Aeronautical Mobile Satellite (Route) Service (AMS(R)S)
in the 1.6 GHz, 2 GHz, and 5 GHz frequency bands, including whether to
revise the AMS(R)S technical standards to accommodate additional
satellite systems and whether to accord priority and preemptive access
to AMS(R)S communications in these bands; (ii) proposes to delete a
regulatory provision which permits limited use of the VHF band for
AMS(R)S communications; (iii) invites comment on whether the Commission
should consider proposing rules that would require a transition to 8.33
kHz channelization in the aeronautical enroute service; (iv) invites
comment on whether the Commission should reduce the number of
frequencies designated for Flight Information Services--Broadcast (FIS-
B); (v) proposes to codify the terms of special temporary
authorizations (STAs) permitting the use of specified frequencies for
air-to-air communications in Hawaii and in the Los Angeles area; (vi)
proposes to clarify the circumstances under which an airport is limited
to a single aeronautical advisory station (unicom); (vii) invites
comment on whether the Commission should permit the assignment and
transfer of control of aircraft radio licenses; and (viii) invites
comment on whether the Commission should phase out its authorization of
emergency locator transmitters (ELTs) designed to operate on 121.5 MHz.

C. Paperwork Reduction Act
14. This document does not contain proposed information
collection(s) subject to the Paperwork Reduction Act of 1995 (PRA),
Public Law 104-13. In addition, therefore, 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
15. As required by the Regulatory Flexibility Act (RFA), the
Commission has prepared this present Initial Regulatory Flexibility
Analysis (IRFA) of the possible significant economic impact on small
entities by the policies and rules proposed in the Second FNPRM.
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 Second FNPRM as provided in paragraph 49 of the
item. The Commission will send a copy of the Second FNPRM, including
this IRFA, to the Chief Counsel for Advocacy of the U.S. Small Business
Administration. In addition, a copy of the Second FNPRM and IRFA (or
summaries thereof) will also be published in the Federal Register.
Need for, and Objectives of, the Proposed Rules:
16. The proposed rules in the Second FNPRM are intended to further
streamline, consolidate and clarify the Commission's part 87 rules;
remove unnecessary or duplicative requirements; address new
international requirements; and promote flexibility and efficiency in
the use of aviation radio equipment in a manner that will further
aviation safety. In the Second FNPRM, the Commission requests comment
specifically on whether the Commission should: (a) Broaden the AMS(R)S
rules to accommodate the provision of AMS(R)S by additional satellite
systems; (b) mandate that AMS(R)S communications in the 1.6 GHz, 2 GHz,
and 5 GHz frequency bands be given priority and preemptive access; (c)
delete a regulatory provision which permits limited use of the VHF band
for AMS(R)S communications; (d) consider proposing rules that would
require a transition to 8.33 kHz channelization in the aeronautical
enroute service; (e) reduce the number of frequencies designated for
FIS-B; (f) codify the terms of an STA permitting the use of specified
frequencies for air-to-air communications in Hawaii; (g) codify the
terms of an STA permitting the use of specified frequencies for air-to-
air communications in the Los Angeles area; (h) clarify the
circumstances under which an airport is limited to a single
aeronautical advisory station (unicom); (i) permit the assignment and
transfer of control of aircraft radio licenses; and (j) phase out the
authorization of ELTs designed to operate on 121.5 MHz.
Legal Basis for Proposed Rules:
17. Authority for issuance of this item is contained in sections
4(i), 303(r), and 403 of the Communications Act of 1934, as amended, 47
U.S.C. 154(i), 303(r) and 403.
Description and Estimate of the Number of Small Entities to Which
the Proposed Rules Will Apply:
18. 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.''
19. Small businesses in the aviation and marine radio services use
a marine very high frequency (VHF), medium frequency (MF), or high
frequency (HF) radio, any type of emergency position indicating radio
beacon (EPIRB) and/or radar, an 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
[[Page 70712]]
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.
20. 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 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.
21. Some of the rules proposed herein may also affect providers of
satellite telecommunications services. There is no small business size
standard developed specifically for providers of international service.
The appropriate size standards under SBA rules are for the two broad
census categories of ``Satellite Telecommunications'' and ``Other
Telecommunications.'' Under both categories, such a business is small
if it has $13.5 million or less in average annual receipts.
22. The first category of Satellite Telecommunications ``comprises
establishments primarily engaged in providing point-to-point
telecommunications services to other establishments in the
telecommunications and broadcasting industries by forwarding and
receiving communications signals via a system of satellites or
reselling satellite telecommunications.'' For this category, Census
Bureau data for 2002 show that there were a total of 371 firms that
operated for the entire year. Of this total, 307 firms had annual
receipts of under $10 million, and 26 firms had receipts of $10 million
to $24,999,999. Consequently, we estimate that the majority of
Satellite Telecommunications firms are small entities that might be
affected by our action.
23. The second category of Other Telecommunications ``comprises
establishments primarily engaged in (1) providing specialized
telecommunications applications, such as satellite tracking,
communications telemetry, and radar station operations; or (2)
providing satellite terminal stations and associated facilities
operationally connected with one or more terrestrial communications
systems and capable of transmitting telecommunications to or receiving
telecommunications from satellite systems.'' For this category, Census
Bureau data for 2002 show that there were a total of 332 firms that
operated for the entire year. Of this total, 259 firms had annual
receipts of under $10 million and 15 firms had annual receipts of $10
million to $24,999,999. Consequently, we estimate that the majority of
Other Telecommunications firms are small entities that might be
affected by our action.
Description of Projected Reporting, Recordkeeping, and Other
Compliance Requirements:
24. Most of the possible rule changes under consideration in the
Second FNPRM generally would not impose any new compliance requirements
on any entity. The proposals to codify existing STAs would, if adopted,
relieve aircraft operators in Hawaii and the Los Angeles area of the
regulatory restrictions that impelled them to seek those STAs. With two
exceptions, the Commission believes the other proposed rules would have
no significant effect on the compliance burdens of regulatees. The
Commission invites comment on its tentative conclusion that the
following 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: (1) Reducing the number of frequencies
designated for FIS-B; (2) codifying the terms of the STA permitting the
use of specified frequencies for air-to-air communications in Hawaii;
(3) codifying the terms of the STA permitting the use of specified
frequencies for air-to-air communications in the Los Angeles area; (4)
clarifying the circumstances under which an airport is limited to a
single unicom; (5) permitting the assignment and transfer of control of
aircraft radio licenses; (6) phasing out the authorization of ELTs
designed to operate on 121.5 MHz; and (7) deleting a regulatory
provision which permits limited use of the VHF band for AMS(R)S
communications. 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, the Commission
asks that they describe the nature of that burden in some detail and,
if possible, quantify the costs to small entities.
25. The Commission is considering in the Second FNPRM whether to
mandate that mobile satellite systems providing AMS(R)S accord priority
and preemptive access to AMS(R)S communications vis-a-vis public
correspondence and other non-safety-related communications in the 1.6
MHz, 2 MHz, and 5 MHz bands, as they already are required to do in the
1545-1559 MHz and 1646.5-1660.5 MHz bands. To the extent that such a
requirement would impose a new compliance burden, however, the burden
would fall only on mobile satellite service (MSS) licensees. MSS
licensees are not small entities. Accordingly, we do not believe this
requirement will have a direct and significant economic impact on any
small entities.
26. In addition, the Commission believes that mandating a
transition to 8.33 kHz channel spacing in the aeronautical enroute
service might impose a new compliance burden on
[[Page 70713]]
aircraft station licensees because of the need to replace existing
avionics equipment designed to operate with 25 kHz channel spacing.
This burden might be incurred not only by the major air carriers, but
also by smaller carriers and others that may qualify as small entities.
In the Second FNPRM, the Commission seeks comment on whether the public
interest benefits of a mandatory narrowbanding of the aeronautical
enroute spectrum would outweigh the costs and difficulties that such an
effort would engender. The Commission seeks estimates of projected
compliance costs, with an explanation of all assumptions on which the
estimates are based. The Commission here reiterates that request, and
specifically asks interested parties to address potential compliance
costs for small entities.
Steps Taken to Minimize Significant Economic Impact on Small
Entities, and Significant Alternatives Considered:
27. 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.
28. In the Second FNPRM, the Commission requests further comment
on, among other things, the nature of any burden that might be incurred
by MSS licensees if required to provide priority and preemptive access
to AMS(R)S communications in the 1.6 GHz, 2 GHz, and 5 GHz frequency
bands. For reasons stated above, the Commission believes MSS licensees
are not small entities. Commenters who believe otherwise are invited to
explain why MSS licensees should be deemed small entities, and to
propose steps, such as those described in the immediately preceding
paragraph, that might eliminate or minimize the burden of a priority
and preemptive access requirement on MSS licensees.
29. In the Second FNPRM, the Commission also seeks comment on
various means of limiting the impact of a transition to 8.33 kHz
channel spacing in the aeronautical enroute service in the event such a
transition is mandated. It asks commenters to suggest the appropriate
duration of any period(s) of transition and to consider whether
grandfathering provisions of some sort should be adopted to mitigate
the costs of retrofitting aircraft. It also asks whether transition
schedules should be staggered based on criteria relating to the size of
the carrier or the class of aircraft. The Commission reiterates those
requests here, and ask interested parties to consider any other means
to lessen potential compliance burdens on small entities if the
Commission ultimately mandates a transition to 8.33 kHz channel spacing
in the aeronautical enroute service. In addition, to the extent
commenters believe any of the other possible rule changes discussed in
the Second FNPRM might impose any significant economic impact on small
entities, the Commission invites them to address any or all of the
aforementioned regulatory alternatives and to suggest additional
alternatives to minimize that impact. Any significant alternative
presented in the comments will be considered.

* * * * *
(b) Only one unicom will be authorized to operate at an airport
which does not have a control tower, RCO or FAA flight service station
that effectively controls traffic at the airport (i.e., where the
unicom frequency is not the published common traffic advisory
frequency). At an airport which has a part-time or full-time control
tower, RCO or FAA flight service station that effectively controls
traffic at the airport, the one unicom limitation does not apply and
the airport operator and all aviation services organizations may be
licensed to operate a unicom on the assigned frequency.
