                       TITLE 47--TELECOMMUNICATION
 
                         COMMISSION (CONTINUED)
 
PART 87--AVIATION SERVICES--Table of Contents
 
                    Subpart D--Technical Requirements
 
Sec. 87.147  Authorization of equipment.

    (a) Certification may be requested by following the procedures in 
part 2 of this chapter. Aircraft transmitters must meet the requirements 
over an ambient temperature range of -20 degrees to +50 degrees Celsius.
    (b) ELTs manufactured after October 1, 1988, must meet the output 
power characteristics contained in Sec. 87.141(i) when tested in 
accordance with the Signal Enhancement Test contained in subpart N, part 
2 of this chapter. A report of the measurements must be submitted with 
each application for certification. ELTs that meet the output power 
characteristics of the section must have a permanent label prominently 
displayed on the outer casing state, ``Meets FCC Rule for improved 
satellite detection.'' This label, however, must not be placed on the 
equipment without authorization to do so by the Commission. Application 
for such authorization may be made either by submission of a new 
application for certification accompanied by the required fee and all 
information and test data required by parts 2 and 87 of this chapter or, 
for ELTs approved prior to October 1, 1988, a letter requesting such 
authorization, including appropriate test data and a showing that all 
units produced under the original equipment authorization comply with 
the requirements of this paragraph without change to the original 
circuitry.
    (c) An applicant for a station license may request certification for 
an individual transmitter by following the procedure in part 2 of this 
chapter. Such a transmitter will be individually certified and so noted 
on the station license.
    (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, Spectrum 
Engineering Division, 800 Independence Ave. SW., Washington, DC 20591 no 
later than the date of filing of the application with the Commission.
    (1) The notification must describe the equipment, give the 
manufacturer's identification, antenna characteristics, rated output 
power, emission type and characteristics, the frequency or frequencies 
of operation, and essential receiver characteristics if protection is 
required.
    (2) The certification application must include a copy of the 
notification letter to the FAA. The Commission will not act for 21 days 
after receipt of the application to afford the FAA an opportunity to 
comment. If the FAA objects to the application for equipment 
authorization, it should mail its objection with a showing that the 
equipment is incompatible with the National Airspace System to: Office 
of Engineering and Technology Laboratory, Authorization and Evaluation 
Division, 7435 Oakland Mills Rd., Columbia, MD

21046. If the Commission receives such an objection, the Commission will 
consider the FAA showing before taking final action on the application.
    (3) The frequency bands are as follows:

74.800 MHz to 75.200 MHz
108.000 MHz to 137.000 MHz
328.600 MHz to 335.400 MHz
960.000 MHz to 1215.000 MHz
1559.000 to 1626.500 MHz
1646.500 MHz to 1660.500 MHz
5000.000 MHz to 5250.000 MHz
14.000 GHz to 14.400 GHz
15.400 GHz to 15.700 GHz
24.250 GHz to 25.250 GHz
31.800 GHz to 33.400 GHz

    (e) Verification reports for ELTs capable of operating on the 
frequency 406.025 MHz must include sufficient documentation to show that 
the ELT meets the requirements of Sec. 87.199(a). A letter notifying the 
FAA of the ELT verification must be mailed to: FAA, Spectrum Engineering 
Division, 800 Independence Avenue SW., Washington, DC 20591.
