FEDERAL COMMUNICATIONS COMMISSION

47 CFR Parts 2 and 87

[WT Docket No. 01-289; FCC 06-148]


Aviation Communications

AGENCY: Federal Communications Commission.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: In this document, the Federal Communications Commission 
(Commission or FCC) addresses a number of important issues pertaining 
to the Aviation Radio Services, amending its frequency allocation and 
radio treaty matters and aviation services rules to ensure that they 
remain up-to-date and continue 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. In many 
cases these rule amendments also promote public safety generally and 
improve our homeland security.

DATES: Effective February 5, 2007.

    1. The Second Report and Order addresses issues raised in the 
Further Notice of Proposed Rule Making (FNPRM) in this WT Docket No. 
01-289 proceeding. The Commission takes the following significant 
actions in the Second Report and Order: (i) Authorizes the use of 
Universal Access Transceiver (UAT) technology on the frequency 978 MHz; 
(ii) declines to adopt any immediate changes to the part 87 rules 
governing the Aeronautical Mobile Satellite (Route) Service (AMS(R)S) 
with respect to technical flexibility, the licensing of AMS(R)S in 
additional frequency bands under part 87, or priority and preemptive 
access for AMS(R)S communications vis-vis public correspondence 
communications and other non-safety-related Mobile Satellite Service 
(MSS) communications; (iii) removes all of the former Civil Air Patrol 
(CAP) channels from the table of frequencies available for assignment 
under part 87; (iv) removes allocations for radionavigation in the 
14000-14400 MHz band; (v) streamlines the listing of high frequency 
(HF) channels in the table of frequencies available for assignment 
under part 87; (vi) provides the Federal Aviation Administration (FAA) 
with greater flexibility in the use of air traffic control (ATC) 
frequencies; (vii) declines to adopt rules that would authorize a new 
type of emergency locator transmitter (ELT) designed to operate on the 
frequency 121.5 MHz; (viii) adopts rules permitting use of an 
alternative station identification format by aircraft that are being 
moved by maintenance personnel from one airport location to another; 
(ix) eliminates the rule authorizing the assignment of FCC control 
numbers to ultralight aircraft for station identification; and (x) 
declines at present to make any rule changes pertaining to the Plan for 
the Security Control of Air Traffic and Air Navigation Aids (SCATANA).

I. Procedural Matters

A. Paperwork Reduction Act Analysis

    2. The Second Report and Order does not contain any new or modified 
information collection requirements 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).

B. Report to Congress

    3. The Commission will send a copy of this Second Report and Order 
in a report to Congress and the Government Accountability Office 
pursuant to the Congressional Review Act, see 5 U.S.C. 801(a)(1)(A).

C. Final Regulatory Flexibility Analysis

    4. As required by the Regulatory Flexibility Act of 1980, as 
amended (RFA), an Initial Regulatory Flexibility Analysis (IRFA) was 
incorporated in the FNPRM in this proceeding. The Commission sought 
written public comment on the proposals in the FNPRM, including comment 
on the IRFA. This present Final Regulatory Flexibility Analysis (FRFA) 
conforms to the RFA.

Need for, and Objectives of, the Report and Order

    5. The rules adopted in the Second Report and Order are intended to 
ensure that the Commission's part 87 rules governing the Aviation Radio 
Service remain up-to-date and continue 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. 
Specifically, in the Second Report and Order the Commission (a) 
authorizes the use of UAT technology on the frequency 978 MHz; (b) 
removes all of the former CAP channels from the table of frequencies 
available for assignment under part 87; (c) removes allocations for 
radionavigation in the 14000-14400 MHz band; (d) streamlines the 
listing of HF channels in the table of frequencies available for 
assignment under part 87; (e) provides the FAA with greater flexibility 
in the use of ATC frequencies; (f) declines to adopt rules that would 
authorize a new type of ELT designed to operate on the frequency 121.5 
MHz; (g) codifies the terms of a waiver permitting use of an 
alternative station identification format by aircraft that are being 
moved by maintenance personnel from one airport location to another; 
(h) eliminates the rule authorizing the assignment of FCC control 
numbers to ultralight aircraft for station identification; and (i) 
declines at present to make any rule changes pertaining to the Plan for 
the Security Control of Air Traffic and Air Navigation Aids (SCATANA).

Summary of Significant Issues Raised by Public Comments in Response to 
the IRFA

    6. No comments were submitted specifically in response to the IRFA. 
Nonetheless, we have considered the potential economic impact on small 
entities of the rules discussed in the IRFA, and we have considered 
alternatives that would reduce the potential economic impact on small 
entities of the rules enacted herein.

Description and Estimate of the Number of Small Entities to Which Rules 
Will Apply

    7. 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 rules adopted herein. The RFA 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 which: (1) Is independently owned and operated; 
(2) is not dominant in its field of operation; and (3) satisfies any 
additional criteria established by the Small Business Administration 
(SBA).
    8. 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 FRFA, 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

[[Page 70673]]

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.
    9. Some of the rules adopted 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.

Description of Projected Reporting, Recordkeeping, and Other Compliance 
Requirements for Small Entities

    10. The Second Report and Order does not impose any additional 
reporting, recordkeeping, or other compliance requirements on small 
entities. The rule amendments adopted in the Second Report and Order 
generally either relieve licensees of pre-existing technical 
constraints or simply streamline and update the Commission's rules in a 
manner that will have no impact at all on regulatory compliance costs.

Steps Taken To Minimize the Significant Economic Impact on Small 
Entities, and Significant Alternatives Considered

    11. The RFA requires an agency to describe any significant 
alternatives that it has considered in developing its approach, which 
may include the following four alternatives (among others): ``(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 and reporting requirements under the rule for such 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 
such small entities.''
    12. As explained in section C of this FRFA, above, the Second 
Report and Order does not impose any additional reporting, 
recordkeeping, or other compliance requirements on small entities. In 
the Second Report and Order, the Commission discusses the possibility 
of further relaxing AMS(R)S technical requirements to accommodate non-
Inmarsat satellite systems, and the Commission did consider, as one 
alternative, immediately amending the part 87 rules for that purpose. 
The Commission ultimately decided, however, that it would be prudent to 
seek further comment on this question, especially in light of the fact 
that the International Civil Aviation Organization (ICAO) has not yet 
adopted Standards and Recommended Practices for such AMS(R)S 
operations. Similarly, the Commission could have adopted part 87 
licensing rules for AMS(R)S in the 1.6 GHz, 2 GHz, and 5 GHz frequency 
bands, subject to a requirement that satellite system operators accord 
priority and preemptive access to AMS(R)S communications over other 
types of communications. The Commission deferred a final decision on 
this matter, primarily to acquire additional information regarding 
whether such a priority and preemptive access requirement is truly 
necessary, and regarding the burden such a requirement may impose on 
MSS/AMS(R)S licensees.

F. Report to Congress

    13. The Commission will send a copy of this Second Report and Order 
in WT Docket No. 01-289, including the Final Regulatory Flexibility 
Analysis, in a report to be sent to Congress pursuant to the 
Congressional Review Act. In addition, the Commission will send a copy 
of the Second Report and Order, including the Final Regulatory 
Flexibility Analysis, to the Chief Counsel for Advocacy of the SBA. A 
copy of the Second Report and Order and the Final Regulatory 
Flexibility Analysis (or summaries thereof) will also be published in 
the Federal Register.

11. Amend Sec.  87.187 by revising paragraphs (p), (q), and (x) and 
adding paragraph (ff) to read as follows:


Sec.  87.187  Frequencies.

* * * * *
    (p) The frequency band 1435-1525 MHz is available on a primary 
basis and the frequency band 1525-1535 MHz is available on a secondary 
basis for telemetry and telecommand associated with the flight testing 
of aircraft, missiles, or related major components. This includes 
launching into space, reentry into the earth's atmosphere and 
incidental orbiting prior to reentry. The following frequencies are 
shared with flight telemetry mobile stations: 1444.5, 1453.5, 1501.5, 
1515.5, and 1524.5 MHz. See Sec.  87.303(d).

    Note to paragraph (p): Aeronautical telemetry operations must 
protect mobile-satellite operations in the 1525-2535 MHz band and 
maritime mobile-satellite operations in the 1530-1535 MHz band.

    (q) The frequencies in the band 1545.000-1559.000 MHz and 1646.500-
1660.500 MHz are authorized for use by the Aeronautical Mobile-
Satellite (R) Service. The use of the bands 1544.000-1545.000 MHz 
(space-to-Earth) and 1645.500-1646.500 MHz (Earth-to-space) by the 
Mobile-Satellite Service is limited to distress and safety operations. 
In the frequency bands 1549.500-1558.500 MHz and 1651.000-1660.000 MHz,
