§  2.403   Retransmission of distress message.

   Any station which becomes aware that a mobile station is in distress
   may transmit the distress message in the following cases:

   (a) When the station in distress is not itself in a position to
   transmit the message.

   (b) In the case of mobile stations, when the master or the person in
   charge of the ship, aircraft, or other vehicles carrying the station
   which intervenes believes that further help is necessary.

   (c) In the case of other stations, when directed to do so by the
   station in control of distress traffic or when it has reason to believe
   that a distress call which it has intercepted has not been received by
   any station in a position to render aid.
