A petition for exemption is a request to the Director of Civil Aviation to provide relief from any specified requirement in a Civil Aviation Rule approved by the Minister. Before granting an Exemption, the Director will consider whether an applicant’s proposal provides a level of safety, or risk control, equivalent to that required by the existing rule.

Applicant Responsibility

Petitions should be accompanied by safety and risk assessments. To be able to successfully assess an application, the CAA requires the documentation and supporting evidence to clearly support the reasons for the Exemption request, including any proposed actions or conditions to maintain an appropriate level of safety.

Legal Criteria

In order to grant an Exemption the Director will need to be satisfied in all cases that the risk to safety will not be significantly increased by the granting of the exemption. It is essential that appropriate evidence is provided to demonstrate that these grounds are met.

The grounds are:

  1. the requirement has been substantially complied with and that further compliance is unnecessary; or
  2. the action taken or provision made in respect of the matter to which the requirement relates is as effective or more effective than actual compliance with the requirement; or
  3. the prescribed requirements are clearly unreasonable or inappropriate in the particular case; or
  4. events have occurred that make the prescribed requirements unnecessary or inappropriate in the particular case –

Exemption Specialist

The role of the CAA Exemptions Specialist is to assess the documentation and supporting evidence supplied, with input from subject matter experts, and provide an evidence based recommendation for the Director’s consideration. The Exemption process requires a CAA technical, policy and legal review before it is presented to the Director.

Processing Time

Applicant should submit an Exemption petition at least 90 days in advance. The CAA will consider an application inside this 90 day window, but there should be no expectation that a short-notice request will receive urgent or priority attention, particularly if the applicant has known about the situation for some time.
