Can the FAA cancel an airspace authorization after it has been approved?

Yes. The FAA may contact a UAS or drone operator if operational conditions have changed and the sUAS operation must be canceled or temporarily suspended. Potential events that might result in canceling or suspending sUAS operations include unexpected incidents involving national security, protection of loss of property or life, or air safety. The FAA will contact the operator using the telephone number provided in the airspace authorization request.
