§  2.406   National defense; free service.

   Any common carrier subject to the Communications Act may render to any
   agency of the United States Government free service in connection with
   the preparation for the national defense. Every such carrier rendering
   any such free service shall make and file, in duplicate, with the
   Commission, on or before the 31st day of July and on or before the 31st
   day of January in each year, reports covering the periods of 6 months
   ending on the 30th day of June and the 31st day of December,
   respectively, next prior to said dates. These reports shall show the
   names of the agencies to which free service was rendered pursuant to
   this rule, the general character of the communications handled for each
   agency, and the charges in dollars which would have accrued to the
   carrier for such service rendered to each agency if charges for all
   such communications had been collected at the published tariff rates.
