  §  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

   (b) ELTs manufactured after October 1, 1988, must meet the output power
   characteristics contained in § 87.141(i). 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, Office
   of Spectrum Policy and Management, ASR-1, 800 Independence Ave., SW.,
   Washington, DC 20591 prior to the filing of the application with the

   (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

   (2) The certification application must include a copy of the
   notification letter to the FAA. The Commission will not act until it
   receives the FAA's determination regarding whether it objects to the
   application for equipment authorization. The FAA should mail its
   determination to: Office of Engineering and Technology Laboratory,
   Authorization and Evaluation Division, 7435 Oakland Mills Rd.,
   Columbia, MD 21046. The Commission will consider the FAA determination
   before taking final action on the application.

   (3) The frequency bands are as follows:

   90-110 kHz

   190-285 kHz

   325-435 kHz

   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

   1545.000 MHz 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) Supplier's Declaration of Conformity for ELTs capable of operating
   on the frequency 406.0-406.1 MHz must include sufficient documentation
   to show that the ELT meets the requirements of § 87.199(a). A letter
   notifying the FAA of the ELT Supplier's Declaration of Conformity must
   be mailed to: FAA, Office of Spectrum Policy and Management, ASR-1, 800
   Independence Avenue SW., Washington, DC 20591.

   Note 1 to paragraph (e): The verification procedure has been replaced
   by Supplier's Declaration of Conformity. Equipment previously
   authorized under subpart J of part 2 of this chapter may remain in use.
   See § 2.950 of this chapter.

   (f) Certification may be requested for equipment that has the
   capability to transmit in the 138-144 MHz, 148-149.9 MHz, or
   150.5-150.8 MHz bands as well as frequency bands set forth in § 87.173.
   The Commission will only certify this equipment for use in the bands
   regulated by this part.
