In order to take advantage of this extension, the administration shall have, within one month of the launch failure or one month after 5 July 2003, whichever comes later, notified the Bureau in writing of such failure, and shall also provide the following information to the Bureau before the end of the regulatory time-limit of § 4.2.6: – date of launch failure; – due diligence information as required in Resolution 49 (Rev.WRC-15) for the assignment with respect to the satellite that suffered the launch failure, if that information has not already been provided. If, 11 months after the request for extension, the administration has not provided to the Bureau updated Resolution 49 (Rev.WRC-15) information, the Bureau shall promptly send a reminder to the notifying administration. If, within one year of the request for extension, the administration has not provided to the Bureau updated Resolution 49 (Rev.WRC-15) information for the new satellite under procurement, the related frequency assignments shall lapse.

If the notifying administration informs the Bureau of the suspension more than 21 months after the date on which the use of the frequency assignment was suspended, the frequency assignment shall be cancelled.
