Design changes

Minor changes by the manufacturer holding an ATSO authorisation

  (1)   An article manufacturer manufacturing an article under an ATSO authorisation may make minor design changes (any change other than a major change) without further approval by CASA. In this case, the changed article keeps the original model number (part numbers may be used to identify minor changes).

  (2)   The manufacturer must forward to CASA any revised data that are necessary for compliance with subregulation   21.605(3).

Penalty:   25 penalty units.

  (2A)   An offence against subregulation   (2) is an offence of strict liability.

Note:   For strict liability , see section   6.1 of the Criminal Code .

Major changes by manufacturer holding an ATSO authorisation

  (3)   Any design change by the manufacturer that is extensive enough to require a substantially complete investigation to determine compliance with an ATSO, ETSO or TSO is a major change . Before making such a change, the manufacturer must assign a new type or model designation to the article and apply for an ATSO authorisation under regulation   21.605.

Who may apply for approval of change

  (4)   A person may apply for approval for a change to the design of an article under this Subpart only if the person:

  (a)   is the manufacturer that submitted the statement of conformance for the article; or

  (b)   has applied for an ATSO authorisation for the article.

Note:   A person may apply to CASA, an authorised person or an approved design organisation, in writing, for a modification/repair design approval for the design of a modification of, or a repair to, an appliance: see Subpart   21.M.
