Implementation procedures for airworthiness - FAQ for design organisations
Implementation Procedures for Airworthiness under the Agreement on the Promotion of Aviation Safety between The Government of the United States of America and The Government of Australia - also known as the 'Bilateral Aviation Safety Agreement' (BASA)
- What is the BASA?
Implementation Procedures for Airworthiness under the BASA allow for the import to the US of certain aeronautical products designed and manufactured in Australia, and Australian acceptance of certain Federal Aviation Administration (FAA) approvals, without the need for a full repeated approval process.
- What changed with the recent Amendment (Amendment 1 to Revision 1)?
The amendment allows for more streamlined US Acceptance of CASA Supplemental Type Certificate (STC) modifications to United States State of Design (SoD) 14 CFR Part 25, 27 and 29 aircraft, and for CASA STC modifications to third country SoD 14 CFR Part 23, 25, 27 and 29 aircraft which have been type certificated by both the FAA and CASA.
- Is there a consolidated document that shows the amended Implementation Procedures for Airworthiness?
No, you need to read three documents:
- Implementation Procedures for Airworthiness Revision 1 dated 7 May 2010,
- Implementation Procedures for Airworthiness, Amendment 1 to Revision 1 dated 22 March 2017, and
- Addendum to the Implementation Procedures for Airworthiness dated 22 March 2017
- Are all Part 25, 27 and 29 STCs eligible?
No, please read Addendum Section 3 for specific details.
CASA recommends industry participants interested in utilising provisions of the BASA ensure they have a thorough understanding of what is and what is not within scope of the BASA prior to making business decisions.
- Are the STC within the scope described in the Addendum Section 3 accepted automatically?
No not necessarily. The STCs are validated by the FAA. The degree of validation varies.
- How do I apply for the FAA to validate a CASA STC?
An application should be made to CASA (email email@example.com) listing the information required by Section 3.0.3 of the IPA Revision 1.
- Can a new manufactured part be released to the USA under a one-off Production Certificate provisions via a CASA form 1 release certificate?
Refer to IPA Revision 1 Section 188.8.131.52 for the detailed requirements. In summary, the design data used in this scenario has to be FAA approved design data. The FAA approved design data could be a CASA approved STC which has been validated by the FAA, via the provision of this BASA. The manufactured part needs to conform to the FAA approved design data. In addition, requirements of CASR 21.133 (2B) needs to met.
