The Experimental Certificate shall be issued subject to such further conditions relating to safety as the CAA thinks fit.

The CAA may, if satisfied by such investigations relating to the safe use of the hovercraft as it may require, vary an Experimental Certificate at the request of an applicant. Such variation may be subject to such further conditions relating to safety as the CAA thinks fit.

An Experimental Certificate shall, unless cancelled or suspended, remain in force for such period not exceeding one year as may be specified therein, and may be renewed from time to time by the CAA for such further period not exceeding one year as it thinks fit.
