Sec. 87.51  Aircraft earth station commissioning.

    (a) Aircraft earth stations which require commissioning to use a 
privately owned satellite system must submit FCC Form 404 to the 
Commission before transmitting on any satellite frequency bands 
allocated for aeronautical mobile-satellite communications.
    (b) Aircraft earth stations authorized to operate in the Inmarsat 
space segment must display the Commission license together with the 
commissioning certificate issued by Inmarsat. Notwithstanding the 
requirements of this paragraph, aircraft earth stations may operate in 
the Inmarsat space segment without an Inmarsat-issued commissioning 
certificate if written approval is obtained from Inmarsat in addition to 
the license from the Commission.
