Certificates of airworthiness (COA.01) - protocol suite

The certificates of airworthiness protocol suite provides a structure for how CASA makes decisions in relation to certificates of airworthiness. It consists of the following documents:

  • Certificates of Airworthiness (COA.01) - Protocol
  • Certificates of Airworthiness (COA.01) - Principle
  • Certificates of Airworthiness (COA.01) - Workbook.

The protocol document provides a summary of the policies, concept and philosophy that sits behind the document suite. It identifies approved supplementary documents that are applicable.

The principle document provides technical guidance guidance to a CASA inspector. This helps them make an informed decision on the suitability of an application. It also ensures we are being consistent and using a standard approach. The question in the principle document relates to a question in the worksheet.

We use the worksheet as a record of the assessment and the decision we make. Each worksheet question relates to a regulatory requirement.

Depending on the nature of the application, you need one or more of the following forms:
