47 C.F.R. Subpart C—Specifications for Obstruction Marking and Lighting of Antenna Structures
Title 47 - Telecommunication
Antenna structures shall be painted and lighted when: (a) They exceed 60.96 meters (200 feet) in height above the ground or they require special aeronautical study. (b) The Commission may modify the above requirement for painting and/or lighting of antenna structures, when it is shown by the applicant that the absence of such marking would not impair the safety of air navigation, or that a lesser marking requirement would insure the safety thereof. [32 FR 11269, Aug. 3, 1967, as amended at 42 FR 54824, Oct. 11, 1977] Whenever painting or lighting is required, the Commission will generally assign specifications in accordance with the FAA Advisory Circulars referenced in §17.23. If an antenna installation is of such a nature that its painting and lighting in accordance with these specifications are confusing, or endanger rather than assist airmen, or are otherwise inadequate, the Commission will specify the type of painting and lighting or other marking to be used in the individual situation. [32 FR 11269, Aug. 3, 1967, as amended at 61 FR 4363, Feb. 6, 1996] Unless otherwise specified by the Commission, each new or altered antenna structure to be registered on or after January 1, 1996, must conform to the FAA's painting and lighting recommendations set forth on the structure's FAA determination of “no hazard,” as referenced in the following FAA Advisory Circulars: AC 70/7460–1J, “Obstruction Marking and Lighting,” effective January 1, 1996, and AC 150/5345–43E, “Specification for Obstruction Lighting Equipment,” dated October 19, 1995. These documents are incorporated by reference in accordance with 5 U.S.C. 552(a). The documents contain FAA recommendations for painting and lighting structures which pose a potential hazard to air navigation. For purposes of this part, the specifications, standards, and general requirements stated in these documents are mandatory. The Advisory Circulars listed are available for inspection at the Commission Headquarters in Washington, DC, or may be obtained from Department of Transportation, Property Use and Storage Section, Subsequent Distribution Office, M483.6, Ardmore East Business Center, 3341 Q 75th Avenue, Landover, MD 20785, telephone (301) 322–4961, facsimile (301) 386–5394. Copies are also available for public inspection at the National Archives and Records Administration (NARA).

Title 47: Telecommunication
PART 17—CONSTRUCTION, MARKING, AND LIGHTING OF ANTENNA STRUCTURES
Subpart C—Specifications for Obstruction Marking and Lighting of Antenna Structures
§ 17.21 Painting and lighting, when required.
§ 17.22 Particular specifications to be used.
§ 17.23 Specifications for painting and lighting antenna structures.
Aviation Red Obstruction Lighting [Reserved]
§§ 17.24-17.43 [Reserved]
§ 17.45 Temporary warning lights.
During construction of an antenna structure, for which red obstruction lighting is required, at least two 116- or 125-watt lamps (A21/TS) enclosed in aviation red obstruction light globes, shall be installed at the uppermost point of the structure. The intensity of each lamp shall not be less than 32.5 candelas. In addition, as the height of the structure exceeds each level at which permanent obstruction lights will be required, two similar lights shall be installed at each such level. These temporary warning lights shall be displayed nightly from sunset to sunrise until the permanent obstruction lights have been installed and placed in operation, and shall be positioned so as to insure unobstructed visibility of at least one of the lights at any normal angle of approach. If practical, the permanent obstruction lights may be installed and operated at each required level as construction progresses.

§ 17.47 Inspection of antenna structure lights and associated control equipment.
The owner of any antenna structure which is registered with the Commission and has been assigned lighting specifications referenced in this part:
(a)(1) Shall make an observation of the antenna structure's lights at least once each 24 hours either visually or by observing an automatic properly maintained indicator designed to register any failure of such lights, to insure that all such lights are functioning properly as required; or alternatively,
(2) Shall provide and properly maintain an automatic alarm system designed to detect any failure of such lights and to provide indication of such failure to the owner.
(b) Shall inspect at intervals not to exceed 3 months all automatic or mechanical control devices, indicators, and alarm systems associated with the antenna structure lighting to insure that such apparatus is functioning properly.
[61 FR 4363, Feb. 6, 1996]
§ 17.48 Notification of extinguishment or improper functioning of lights.
The owner of any antenna structure which is registered with the Commission and has been assigned lighting specifications referenced in this part:
(a) Shall report immediately by telephone or telegraph to the nearest Flight Service Station or office of the Federal Aviation Administration any observed or otherwise known extinguishment or improper functioning of any top steady burning light or any flashing obstruction light, regardless of its position on the antenna structure, not corrected within 30 minutes. Such reports shall set forth the condition of the light or lights, the circumstances which caused the failure, the probable date for restoration of service, the FCC Antenna Structure Registration Number, the height of the structure (AGL and AMSL if known) and the name, title, address, and telephone number of the person making the report. Further notification by telephone or telegraph shall be given immediately upon resumption of normal operation of the light or lights.
(b) An extinguishment or improper functioning of a steady burning side intermediate light or lights, shall be corrected as soon as possible, but notification to the FAA of such extinguishment or improper functioning is not required.
[32 FR 11273, Aug. 3, 1967, as amended at 39 FR 26157, July 17, 1974; 40 FR 30267, July 18, 1975; 61 FR 4364, Feb. 6, 1996]
