New permission required after unacceptable modification

In plain language

If you make major modifications to your foreign-registered drone after getting permission, you cannot fly it until you apply for and receive a new permission from CASA.

Requirement as structured

If a foreign-registered RPA undergoes an unacceptable modification after permission is granted, it must not be operated until a new permission is obtained for the modified aircraft.

Original regulatory text

If, after permission has been granted, an unmanned aircraft to which this section applies is the subject of an unacceptable modification, the aircraft, as modified, must not be operated unless a new permission under this section is granted for the aircraft in its modified form.
