Defence Aviation Safety Authority

Aircraft Structural Integrity (ASI)

What We Do

The ASI Section within DAVENG fulfils two main (yet entirely separate) roles:

  • Conduct Authority functions, related to aircraft structures and aero-mechanical systems for ADF fixed-wing aircraft, to support DASA independently assure Initial and Continuing Airworthiness:
    • prescribe and interpret relevant elements of policy, regulation, design standards and requirements (and promotion thereof)
    • provide technology specialist safety assurance services internal to DASA (for products and processes, and intelligence and enforcement)
      • undertake inspection of compliance demonstration evidence
      • conduct Authority approvals, and where appropriate, issue airworthiness instruments
    • conduct Unsafe Condition Assessments (UCAs) in response to mandatory occurrence reporting
  • Assist regulated entities (CAMOs, SPOs/MTCHOs and contracted TLS providers), in the capacity as a Defence CoE, to support Commanders ensure structurally-airworthy platforms:
    • provide Aircraft Structural Integrity (ASI) services
      • SME assessments, specialist advice and/or DASR 21J design products (under the DAVENG MDOA AUS.DASA.21J.0010)
      • where appropriate and when agreed, undertake resource planning, task coordination and management of ASI Programs (ASIPs) and/or major ASI projects on behalf of CASG
    • execute strategy and govern the Structural Integrity (SI) sovereign capability sponsored by DASA-DAVENG (between DASA-DAVENG, QinetiQ and DSTG)

ADF ASI Symposium

As circumstances permit, ASI Section will coordinate the ADF ASI Symposium.

The ADF Aircraft Structural Integrity Symposium (AASIS) is the only dedicated forum for military Aircraft Structural Integrity in Australasia. The theme varies from year-to-year with past ones being:

  • 2019 AASIS - Innovative Sustainment (Presentations)
  • 2016 AASIS - Capability Through Integrated Aircraft Structural Integrity Programs

The Symposium is targeted at all personnel involved in the acquisition and in-service management of ADF aircraft systems, as well as interested representatives from foreign military forces, science and technology organisations, research and development centres, commercial aerospace organisations, airworthiness regulators and academia.

Registration for the ADF ASI Symposium is free. The cost of travel, accommodation, and incidentals are the responsibility of the delegate's organisation.
Details of future ADF ASI Symposiums will be published on this website under the ‘Education and Training’ section.

ASI Familiarisation Course

ASI Section is currently developing an introductory course for the ADF ASI community, with a specific focus on tailoring the material to benefit Through-Life Support (TLS) contracted ASIP managers. It’s envisaged this ASI Familiarisation Course will cover off on:

  • understanding the different airworthiness requirements, design standards and design philosophies employed for aircraft structure
  • understanding the purpose and principles of in-service ASI management
  • identification of the key Defence policies and regulations that govern structural certification and ASI management
  • identification of the broad roles and responsibilities of stakeholders involved in structural certification and ASI management
  • understanding how to manage structural type design changes, repairs and airworthiness limitation changes
  • understanding of the history and strategic responsibility of the ASI Manager role, and delineation from routine platform sustainment

The course will be available to TLS contracted ASIP Managers and ADF/APS employees responsible for in-service platform support, with ASI implications.
Further information on the course will be available on this website under the ‘Education and Training’ section once finalised.
