Defence Aviation Safety Authority

Propulsion Systems Integrity (PSI)

What We Do

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

  • Conduct Authority functions, related to propulsion systems for ADF fixed and rotary-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 independent safety assurance of reportable occurrences in response to occurrence reporting, including the issue of Airworthiness Directives if required
  • Assist the regulated community (CAMOs, SPOs/MTCHOs and contracted TLS providers), in the capacity as a Defence Centre of Expertise (CoE), to support Commanders ensure the airworthiness of propulsion systems
    • provide PSI services
      • specialist advice and assessments (incl. propulsion systems risk assessments) 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 PSI Program (PSIP) tasks and/or major PSI projects on behalf of CASG
    • execute strategy and govern the Structural Integrity (SI) sovereign capability sponsored by DASA-DAVENG (between DASA-DAVENG, QinetiQ and Defence Science and Technology Group (DSTG))

ADF Wear Debris Analysis

The PSI Section also coordinates WDA activities for ADF platforms in collaboration with DSTG’s WDA laboratory. More information can be found here.

ADF PSI Symposium

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

The ADF PSI Symposium is the only dedicated forum for military propulsion systems in Australasia. It provides an excellent opportunity for organisations and personnel in the ADF propulsion systems community to network and share their knowledge and experience.

The ADF PSI Symposium is open to all personnel involved in the acquisition and in-service management of ADF fixed and rotary-wing propulsion systems. Representatives from the following organisations may also find the ADF PSI Symposium beneficial: foreign militaries, science and technology organisations, universities, industry, and airworthiness authorities.

Registration for the ADF Propulsion Systems Symposium is free. The cost of travel, accommodation, and incidentals are the responsibility of the delegate's organisation. Details of future ADF PSI Symposiums will be published on this website under “Education and Training”.

Propulsion System Engineering Course (PROPSYSENG)

The course is aimed at engineers involved in ADF and civil processes for certifying new propulsion systems, or for those personnel who are managing in-service propulsion systems.

The course runs for 3 days, typically at RAAF Base Amberley. However, in order to mitigate the ongoing disruptions caused by COVID-19, PROPSYSENG is currently being delivered virtually through the Australian Defence Education Learning Environment (ADELE). With the intent to return to face-to-face learning when possible.

Attendance at the course is free for ADF personnel and Australian Public Service (APS) employees and at a cost for industry participants. However, while the course is being delivered online, there will be a reduced cost for industry members.

Further information on the course is available here

Propulsion System Integrity Management Plan (PSIMP)

Due to the Commercial-In-Confidence nature of the PSIMPs, they are unable to be hosted on the DASA Internet website. Please contact the relevant PSI Manager or DASA PSI Desk officer if you require a copy of any of these PSIMPs.
