Subpart 21.D—Changes to type certificates

21.091  Applicability
  This Subpart deals with the approval of changes to type certificates.
Source FARs section 21.91 modified.

21.093  Classification of changes in type design
  Changes in type design are classified as minor or major. A minor change is one that has no appreciable effect on the weight, balance, structural strength, reliability, operational characteristics, or other characteristics affecting the airworthiness of an aircraft, aircraft engine or propeller. All other changes are major changes.
Source FARs section 21.93 modified.

21.095  Approval of minor changes in type design
 (1) The holder of a type certificate for an aircraft, aircraft engine or propeller may apply to CASA, an authorised person or a relevant approved design organisation, in writing, for approval of a minor change in the type design of the aircraft, aircraft engine or propeller.
 (2) Subregulation (3) applies if the application is made to CASA or an authorised person.
 (3) Subject to regulation 11.055, CASA or the authorised person must grant the approval if the type design, as modified by the minor change, would meet the requirements of this Part for the type design.
 (4) Subregulation (5) applies if, under regulation 21.251, CASA authorises a relevant approved design organisation to determine whether the design would meet a requirement.
 (5) If the approved design organisation is satisfied that the design would meet the requirement, the organisation may give CASA a certificate to that effect.
 (6) For subregulation (3), if an approved design organisation gives CASA a certificate under subregulation (5), CASA need consider only that certificate in deciding whether the design would meet the requirement.
 (7) Subregulation (8) applies if the application is made to an approved design organisation.
 (8) Subject to regulation 11.055, the approved design organisation must grant the approval if the type design, as modified by the minor change, would meet:
 (a) the requirements of this Part for the type design; and
 (b) any requirements mentioned in the organisation's exposition.

21.097  Eligibility for approval of major changes in type design
 (1) The holder of a type certificate for an aircraft, aircraft engine or propeller is eligible to apply to CASA, an authorised person or a relevant approved design organisation, in writing, for approval of a major change in the type design of the aircraft, aircraft engine or propeller.
 (2) An applicant is entitled to the approval if the applicant:
