49. Where the owner, the operator or a flight crew member of, or an
authorised person engaged (whether as an employee or on his or her own behalf)
in the maintenance of, an aircraft in respect of which a maintenance release
is in force considers:

   (a)  that the aircraft has developed a defect, or has suffered damage, that
        is a permissible unserviceability; and

   (b)  that there is a likelihood that the aircraft will be flown before the
        permissible unserviceability is rectified; he or she shall enter on
        the maintenance release, or other document approved for use as an
        alternative to the maintenance release for the purposes of this
        regulation, an endorsement signed by him or her:

   (c)  setting out each permissible unserviceability that exists with respect
        to the aircraft;

   (d)  setting out such of the conditions (if any) with respect to the use of
        an aircraft with those permissible unserviceabilities set out in any
        direction given under regulation 37 in relation to those permissible
        unserviceabilities as are not set out in any operations manual issued
        with respect to the aircraft or in Part 20 of the
        Civil Aviation Orders; and

   (e)  stating that the maintenance release has effect subject to those
        conditions, whether set out in the maintenance release or the other
        document or otherwise.
