(1) This regulation applies if CASA or the authorised person or approved design organisation is not satisfied that the proposed airworthiness standards for the design provide an adequate safety standard for the design in a particular respect.
Example: The modification or repair has a novel or unusual design feature.
(2) CASA or the authorised person or approved design organisation may determine additional airworthiness standards for the design.
Note: An additional airworthiness standard imposed in respect of a design is often called a 'special condition'.
(3) The additional airworthiness standards must be appropriate to provide a level of safety for the aircraft, aircraft engine, propeller or appliance equivalent to the level of safety required by these Regulations for a comparable aircraft, aircraft engine, propeller or appliance.
(4) CASA or the authorised person or approved design organisation must notify the applicant, in writing, of the determination.
