AGENCY: Federal Communications Commission.

ACTION: Proposed rule.

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

SUMMARY: In this Notice of Proposed Rule Making (NPRM), the FCC 
proposes to consolidate, revise, and streamline the Commission rules 
governing the Aviation Radio Service. The proposed rule changes are 
designed to ensure that these rules reflect recent technological 
advances, as well as ensuring that these rules are consistent with 
other Commission rules. The FCC is initiating this proceeding to 
eliminate regulations that are duplicative, outmoded, or otherwise 
unnecessary in the Aviation Radio Service.

(202) 418-0260 or TTY (202) 418-2555.
    OMB Approval Number: 3060-xxxx.
    Title: Section 87.109 Station logs.
    Form No.: Not applicable.
    Type of Review: New collection.
    Respondents: 3.
    Number of Responses: 3.
    Estimated Time Per Response: 100 hours.
    Total Annual Burden: 300 hours.
    Estimated costs per respondent: none.
    Needs and Uses: The rule is needed to require fixed station in the 
international aeronautical mobile service to maintain a written or 
automatic log in accordance with the provisions of the International 
Civil Aviation Organization (ICAO) Convention. The log is necessary to 
document the service fixed stations, including the harmful 
interference, equipment failure and logging of distress and safety 
calls where applicable.
    OMB Approval Number: 3060-xxxx.
    Title: Section 87.147 Authorization of equipment.
    Form No.: Not applicable.
    Type of Review: New collection.
    Respondents: 25.
    Number of Responses: 25.
    Estimated Time Per Response: 1 hours.
    Total Annual Burden: 25 hours.
    Estimated costs per respondent: none.
    Needs and Uses: The rule is needed to require applicants for 
aviation equipment certification to submit an FAA determination of the 
equipment's compatibility with the National Airspace System (NSA). This 
will ensure that radio equipment operating in certain frequencies is 
compatible with the NAS, which shares system components with the 
military.
    1. The Aviation Radio Service is an internationally-allocated 
family of radio services designed to enhance and protect the safety of 
life and property in air navigation. In this NPRM we propose to 
consolidate, revise, and streamline our Part 87 rules governing the 
Aviation Radio Service. These proposed rule changes are designed to 
ensure that these rules reflect recent technological advances, as well 
as ensuring that these rules are consistent with other Commission 
rules. We are also initiating this proceeding to eliminate regulations 
that are duplicative, outmoded, or otherwise unnecessary in the 
Aviation Radio Service.
    2. In the NPRM, we propose to update the technical specifications 
for Aeronautical Mobile Satellite (Route) Service (AMS(R)S) equipment; 
amend our equipment certification procedures to permit the 
certification of dual spacing transceivers for aircraft also operating 
in countries which employ 8.33 kHz channel spacing; allow the 
certification of radios that operate outside the civil aviation band 
for aircraft in the Civil Reserve Airfleet, and streamline the 
certification process for equipment needing a Federal Aviation 
Administration (FAA) showing of compatibility with the National 
Airspace System.
    3. The NPRM also prepares to authorize the use of the Differential 
Global Positioning System (DGPS) in the 108-118 and 1559-1610 MHz bands 
and license DGPS licensees on a non-developmental basis, and allow the 
use of temporary call signs for aircraft operation under the provisions 
of wet lease agreements.
    4. The NPRM also seeks comment on major issues such as:
    (1) Whether to authorize AMS(R)S under the 47 CFR part 87 rules in 
the 1610-1626.5 and 5000-5150 MHz bands;
    (2) Whether to amend Sec. 87.261(c) of our rules to allow more than 
one aeronautical enroute station to be authorized at any one location;
    (3) Whether to amend our 47 CFR part 87 rules to accommodate Time 
Division Multiple Access emissions in the very high frequency 
Aeronautical Mobile (Route) Service (AMRS) band, as an alternative to 
8.33 kHz channel spacing to allow greater use of spectrum for domestic 
air travel;
    (4) Whether to eliminate all specific references to the Civil Air 
Patrol in Part 87; and
    (5) Whether to revise our licensing rules and procedures for 
aeronautical advisory (unicom) stations.

Procedural Matters

    5. Ex Parte Rules. This is a permit-but-disclose notice and comment 
rule making proceeding. Ex parte presentations are permitted, except 
during the Sunshine Agenda period, provided they are disclosed as 
provided in our Rules.
    6. Comment Dates. Pursuant to Secs. 1.415 and 1.419 of our Rules, 
interested parties may file comments on or before March 14, 2002, and 
reply comments on or before April 15, 2002. Comments may be filed using 
the Commission's Electronic Filing System (ECFS) or by filing paper 
copies.
    7. Comments filed through the ECFS can be sent as an electronic 
file via the Internet to http://www.fcc.gov/e-file/ecfs.html. 
Generally, only one copy of an electronic submission must be filed. If 
multiple docket or rulemaking numbers appear in the caption of this 
proceeding, however, then commenters must transmit one electronic copy 
of the comments to each docket or rulemaking number referenced in the 
caption. In completing the transmittal screen, commenters should 
include their full name, Postal Service mailing address, and the 
applicable docket or rulemaking number. Parties may also submit an 
electronic comment by Internet e-mail. To obtain filing instructions 
for e-mail comments, commenters should send an e-mail to [email protected], 
and should include the following words in the body of the message, 
``get form your e-mail address>.'' A sample form and directions will be 
sent in reply.
    8. Parties who choose to file by paper must file an original and 
four copies of each filing. If more than one docket or rulemaking 
number appears in the caption of this proceeding, commenters must 
submit two additional copies for each additional docket or rulemaking 
number. All filings must be sent to the Commission's Secretary, Magalie 
Roman Salas, Office of the Secretary, Federal Communications 
Commission, 445 12th St., SW., Room TW-A325, Washington, DC 20554.
    9. Parties who choose to file by paper should also submit their 
comments on diskette. These diskettes should be submitted to Jeffrey 
Tobias, Public Safety and Private Wireless Division, Wireless 
Telecommunications Bureau, 445 12th St., SW., Washington, DC 20554. 
Such a submission should be on a 3.5-inch diskette formatted in an IBM 
compatible format using Microsoft Word 97 or compatible software. The 
diskette should be accompanied by a cover letter and should be 
submitted in ``read only'' mode. The diskette should be clearly labeled 
with the commenter's name, proceeding (including the docket number in 
this case, WT Docket No. 01-289, type of pleading (comment or reply 
comment), date of submission, and the name of the electronic file on 
the diskette. The label should also include the following phrase ``Disk 
Copy--Not an Original.'' Each diskette should contain only one party's 
pleadings, preferably in a single electronic file. In addition, 
commenters should send diskette copies to the Commission's copy 
contractor, Qualex International, Portals II, 445 Twelfth St., SW., 
Room CY-B402, Washington, DC 20554.

Initial Regulatory Flexibility Certification

    10. The Regulatory Flexibility Act (RFA) requires that an agency 
prepare a regulatory flexibility analysis for notice-and-comment 
rulemaking proceedings, unless the agency certifies that ``the rule 
will not, if promulgated, have a

[[Page 64787]]

significant economic impact on a substantial number of small 
entities.'' The RFA generally defines ``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).
    11. The proposals in the NPRM are intended to reduce the 
administrative burden on applicants and entities seeking certification 
of equipment, ensure that the Commission's rules reflect the latest 
technical and industry standards, and correct typographical or 
ministerial errors in the Commission's Rules. The changes we propose 
are of an administrative nature, and will not have a substantial 
economic impact on small entities. If there is an economic impact on 
small entities as a result of these proposals, however, we expect the 
impact to be a positive one.
    12. The Commission therefore certifies, pursuant to the RFA, that 
the proposals in this NPRM, if adopted, will not have a significant 
economic impact on a substantial number of small entities. If 
commenters believe that the proposals discussed in the NPRM require 
additional RFA analysis, they should include a discussion of these 
issues in their comments and additionally label them as RFA comments. 
The Commission will send a copy of the NPRM, including a copy of this 
initial certification, to the Chief Counsel for Advocacy of the SBA. In 
addition, a copy of the NPRM and this initial certification will be 
published in the Federal Register.

redesignating paragraphs (i)(3) and paragraph (i)(4) as paragraphs 
(i)(2) and (i)(3) and revising paragraphs (i)(1) and newly redesignated 
paragraph (i)(3) to read as follows:


Sec. 87.139  Emission limitations.

* * * * * * *
    (i)* * *
    (1) At rated output power, while transmitting a modulated single 
carrier, the composite spurious and noise output shall be attenuated 
below the mean power of the transmitter, pY, by at least:

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

paragraphs (d) and (d) (2) to read as follows:


Sec. 87.147  Authorization of equipment.

* * * * *
    (d) An applicant for certification of equipment intended for 
transmission in any of the frequency bands listed in paragraph (d)(3) 
of this section must notify the FAA of the filing of a certification 
application. The letter of notification must be mailed to: FAA, Office 
of Spectrum Policy and Management, 800 Independence Ave., SW., 
Washington, DC 20591 prior to the filing of the application with the 
Commission.
* * * * *
    (2) The certification application must include a copy of the 
notification letter to the FAA as well as a copy of the FAA's 
subsequent determination of the equipment's compatibility with the 
National Airspace System.
