The Civil Aviation Safety Authority has postponed planned changes to CASR Part 66.
The small aircraft maintenance licensing arrangements were to have come in last Monday 4 July, but maintenance training organisations and associations flagged ongoing issues with the suite of regulations.
"Key stakeholders and CASA recognised there were still outstanding issues to be resolved and some unintended consequences as a result of the proposed new small aircraft maintenance personnel structure," a CASA statement released today said.
"Issues relate to maintenance workforce flexibility, career progression and the workload for maintenance training and registered training organisations.
"In addition, more work needs to be done to ensure the regulatory requirements and the vocational training system can work effectively together."
CASA will now conduct a comprehensive review of Part 66, including working with the national education body to produce a more streamlined training package.
