I. Procedural Matters

A. Ex Parte Rules—Permit-But-Disclose Proceeding

2. This is a permit-but-disclose notice and comment rulemaking proceeding. Ex parte presentations are permitted, except during the Sunshine Agenda period, provided they are disclosed as provided in the Commission's rules.

B. Comment Dates

3. Pursuant to §§ 1.415 and 1.419 of the Commission's rules, 47 CFR 1.415, 1.419, interested parties may file comments on or before July 12, 2004 and reply comments on or before August 10, 2004. Comments may be filed using the Commission's Electronic Comment Filing System (ECFS) or by filing paper copies.

4. 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, 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 get filing instructions for e-mail comments, commenters should send an e-mail to [e-mail], 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. 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 addressed to the Commission's Secretary, Marlene H. Dortch, Office of the Secretary, Federal Communications Commission, 445 12th St., SW., Washington, DC 20554. Filings can be sent first class by the U.S. Postal Service, by an overnight courier or hand and message-delivered. Hand and message-delivered paper filings must be delivered to 236 Massachusetts Avenue, NE., Suite 110, Washington, DC 20002. Overnight courier (other than U.S. Postal Service Express Mail and Priority Mail) must be sent to 9300 East Hampton Drive, Capitol Heights, MD 20743.

5. Parties who choose to file by paper should also submit their comments on diskette. These diskettes should be submitted to: Jeffrey Tobias, Wireless Telecommunications Bureau, 445 12th St., SW., Room 4-A366, Washington, DC 20554. Such a submission should be on a 3.5 inch diskette formatted in an IBM compatible format using Microsoft Word 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 lead 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, Inc., 445 12th St., SW., Room CY-B402, Washington, DC 20054.

C. Paperwork Reduction Act

6. This FNPRM does not contain any new or modified information collection.

II. Initial Regulatory Flexibility Analysis

7. As required by the RFA, the Commission has prepared an Initial Regulatory Flexibility Analysis (IRFA) of the rules proposed or discussed in the FNPRM. Written public comments are requested on the IRFA. These comments must be filed in accordance with the same filing deadlines for comments on the FNPRM in WT Docket No. 01-289, and they should have a separate and distinct heading designating them as responses to the IRFA. The Commission's Consumer and Governmental Affairs Bureau, Reference Information Center, will send a copy of the FNPRM, including the IRFA, to the Chief Counsel for Advocacy of the Small Business Administration, in accordance with the Regulatory Flexibility Act.

A. Need for, and Objectives of, the Proposed Rules

The proposed rules in the 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 FNPRM, we request comment specifically on whether we should: (i) Accommodate use of Universal Access Transceiver technology on the frequency 978 MHz; (ii) eliminate all requirements specific to data rates and modulation types to accommodate new technologies, such as Inmarsat's new 64 kbps service; (iii) enable the use of non-geostationary satellite networks for AMS(R)S; (iv) broaden the AMS(R)S regulations to take account of satellite systems other than Inmarsat's; (v) adopt additional technical requirements for AMS(R)S; (vi) identify new uses for the frequencies formerly reserved for the Civil Air Patrol; (vii) remove the radionavigation allocation at 14000-14400 MHz; (viii) streamline the listing of HF band frequencies in part 87 frequency tables; (ix) expand the availability of air traffic control spectrum for ground control communications; (x) codify the terms of a waiver that has permitted the certification of a back-up safety device designed to supplement conventional 121.5 MHz Emergency Locator Transmitters (ELTs); and (xi) codify the terms of a waiver that authorizes a special station identification format to be used only by aircraft being operated by maintenance personnel from one location in an airport to another location in an airport.

B. Legal Basis for Proposed Rules

8. The proposed action is authorized under 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.

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

9. Under the RFA, small entities may include small organizations, small businesses, and small governmental jurisdictions, or entities. 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: (i) Is independently owned and operated; (ii) is not dominant in its field of operation; and (iii) 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.”

10. Small businesses in the aviation and marine radio services use a marine very high frequency (VHF) radio, any type of emergency position indicating radio beacon (EPIRB) and/or radar, a VHF 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 a small entity is that under SBA rules applicable to “Cellular and Other Wireless Telecommunications.” This definition provides that a “small entity” for purposes of public coast station licensees, a subgroup of marine radio users, consists of all such firms having 1,500 or fewer employees. According to Census bureau data for 1997, there were 977 firms, total, in the category of “Cellular and other Wireless Telecommunications,” that operated for the entire year. Of this total, 965 firms had employment of 999 or fewer employees, and an additional 12 firms had employment of 1,000 employees or more. Thus under this size standard, the majority of firms can be considered small.

11. The proposed amendments may also affect small businesses that manufacture aviation radio equipment. The Commission has not developed a definition of small entities applicable specifically to Radio Frequency Equipment Manufacturers (RF Manufacturers). Therefore, the applicable definition of a small entity is the definition under SBA rules for manufacturers of “Radio and Television Broadcasting and Wireless Communications Equipment.” This NAICS category, however, is broad, and specific figures are not available as to how many of these establishments manufacture RF equipment for aviation use. Under the SBA's regulations, a radio and television broadcasting and wireless communications equipment manufacturer must have 750 or fewer employees in order to qualify as a small business concern. Census Bureau data indicates that there are 1,215 U.S. establishments that manufacture radio and television broadcasting and wireless communications equipment, and that 1,150 of these establishments have fewer than 500 employees and would be classified as small entities. The remaining 65 establishments have 500 or more employees; however, we are unable to determine how many of those have fewer than 750 employees and therefore, also qualify as small entities under the SBA definition. We therefore conclude that there are no more than 1,150 small manufacturers of radio and television broadcasting and wireless communications equipment.

D. Description of Projected Reporting, Recordkeeping, and Other Compliance Requirements

12. The FNPRM seeks comment on a number of possible rule changes that may affect reporting, recordkeeping and other compliance requirements. However, we believe that, with the exception of possible rule changes imposing additional technical requirements for certain aircraft earth stations, all of the possible rule changes discussed in the FNPRM are deregulatory in the sense that they do not impose new requirements on licensees or equipment manufacturers, but instead enhance the ability of licensees and manufacturers to provide and use new services and equipment on a permissive basis, and therefore will benefit small entities as well as the aviation community as a whole.

13. We invite comment on our tentative conclusion that the following possible rule changes will not have a negative impact on small entities, or for that matter any entities, because they would facilitate flexible use of the spectrum by licensees and/or design flexibility for manufacturers of avionics equipment, and do not impose new compliance costs on any entity: (i) Accommodating use of Universal Access Transceiver technology on the frequency 978 MHz; (ii) eliminating all requirements specific to data rates and modulation types; (iii) enabling the use of non-geostationary satellite networks for AMS(R)S; (iv) broadening the AMS(R)S regulations to take account of satellite systems other than Inmarsat's; (v) authorizing use of the 1990-2025 MHz band for AMS(R)S; (vi) reallocating the frequencies formerly reserved for the Civil Air Patrol; (vii) removing the radionavigation allocation at 14000-14400 MHz; (viii) streamlining the listing of HF band frequencies in part 87 frequency tables; (ix) expanding the number of air traffic control frequencies available for ground control communications; (x) permitting certification of back-up safety devices designed to supplement conventional 121.5 MHz Emergency Locator Transmitters (ELTs); and (xi) authorizing a special station identification format to be used by aircraft that are being operated by maintenance personnel from one location in an airport to another location in an airport. 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.

14. We tentatively conclude that any compliance burden stemming from new technical requirements for aircraft earth stations used in the provision of AMS(R)S will fall not on small entities but on large entities, such as mobile satellite system operators, airlines, and large manufacturers. We invite comment on this tentative conclusion. Commenters should identify with particularity those small entities that may be affected by these requirements, and, if possible, quantify the costs of any such requirements.

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

15. 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: (i) The establishment of differing compliance or reporting requirements or timetables that take into account the resources available to small entities; (ii) the clarification, consolidation, or simplification of compliance or reporting requirements under the rule for small entities; (iii) the use of performance, rather than design, standards; and (iv) an exemption from coverage of the rule, or any part thereof, for small entities.

16. We hereby request comment on whether we can employ any of the above approaches to lessen compliance burdens on small entities if we adopt new technical requirements for aircraft earth stations. To the extent commenters believe that other of the discussed rule changes would also impose a compliance burden on small entities, we ask that they address whether any of the above approaches to reduce that burden is appropriate.

17. 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

None.

4. Section 87.139 is amended by adding paragraph (l) to read as follows:

§ 87.139

Emission limitations.

* * * * *

(l)(1) For Universal Access Transceiver transmitters, the average emissions measured in a 100 kHz bandwidth must be attenuated below the maximum emission level by at least:

Frequency (MHz)	Attenuation (dB)
+/−0.5	0

+/−2.25	50
+/−3.25	60

The mask shall be defined by drawing straight lines through the above points on log semi-paper.

(2) Universal Access Transceiver transmitters with an output power of 5 Watts or more must limit their emissions by at least 43 + 1-log (P) dB on any frequency removed from the assigned frequency by more than 250% of the occupied bandwidth. Occupied bandwidth is defined as 99% of the signal power measured with a bandwidth of 100 kHz. P in the above equation is the average transmitter power measured in Watts.

(3) Universal Access Transceiver transmitters with less than 5 Watts of output power must limit their emissions by at least 40 dB relative to the carrier peak on any frequency removed from the assigned frequency by more than 250% of the occupied bandwidth. Occupied bandwidth is defined as 99% of the signal power measured with a bandwidth of 100 kHz.

5. Section 87.141 is amended by adding paragraph (k) to read as follows:

§ 87.141

Modulation requirements.

* * * * *

(k) Universal Access Transceiver transmitters must use F1D modulation without phase discontinuities.

6. Section 87.173 is amended by revising the table in paragraph (b) to read as follows:
