CIVIL AVIATION SAFETY REGULATIONS 1998 - REG 21.101

Designation of applicable regulations

  (1)   An applicant for approval of a change in the type design described or identified in a type certificate must comply with either:

  (a)   the airworthiness standards mentioned in the type certificate; or

  (b)   the applicable airworthiness standards in effect on the date of the application, plus any other amendments that CASA is satisfied are directly related.

  (2)   If CASA is satisfied that a proposed change consists of a new design or a substantially complete redesign of a component, equipment installation, or system installation, and that the airworthiness standards mentioned in the type certificate for the aircraft, aircraft engine or propeller do not provide adequate standards with respect to the proposed change, the applicant must comply with:

  (a)   the applicable provisions of these Regulations, in effect on the date of the application for the change, that CASA is satisfied are necessary to provide a level of safety equivalent to that established by the airworthiness standards mentioned in the type certificate; and

  (b)   any special conditions, and amendments to those special conditions, prescribed by CASA to provide a level of safety equal to that established by the airworthiness standards mentioned in the type certificate.

  (3)   Unless otherwise required by subregulation   21.019(1), an applicant for a change to a type certificate for a transport category aeroplane involving the replacement of reciprocating engines with the same number of turbopropeller powerplants must comply with the provisions of Part   25 of the FARs for the aeroplane as type certificated with reciprocating engines, and with the following:

  (a)   the certification performance requirements prescribed in sections   25.101 to 25.125 (inclusive) and 25.149, 25.1533, 25.1583, and 25.1587 of Part   25 of the FARs;

  (b)   the powerplant requirements of Part   25 of the FARs that apply to turbopropeller engine - powered aeroplanes;

  (c)   the requirements of Part   25 of the FARs for the standardisation of cockpit controls and instruments, unless CASA is satisfied that compliance with a particular detailed requirement would be impractical and would not contribute materially to standardisation;

  (d)   any other requirement of Part   25 of the FARs that applies to turbopropeller engine - powered aeroplanes that CASA is satisfied relates to the changes in engines and that is necessary to ensure a level of safety equal to that of the aeroplane certificated with reciprocating engines.

  (4)   For subregulation   (3), for each new limitation established with respect to weight, speed, or altitude that is significantly altered from those approved for the aeroplane with reciprocating engines, the applicant must show compliance with the requirements of Part   25 of the FARs applicable to the limitations being changed.

Source   FARs section   21.101 modified.

Subpart   21.E -- Supplemental type certificates

Note:   A supplemental type certificate issued under this Part for an aircraft, aircraft engine or propeller does not certify that it complies with the Air Navigation (Aircraft Noise) Regulations   2018 , the Air Navigation (Aircraft Engine Emissions) Regulations or any other applicable Commonwealth legislation. Compliance with those Regulations or other applicable Commonwealth legislation may be required before the aircraft, aircraft engine or propeller may be legally operated.
