Qantas could cut more jobs as 30 engineers are expected to be shown the door after recent disputes with recent changes in maintenance procedures.

Even though the airline announced last week that it no longer required safety checks on all aircraft before every domestic flight, the Australian Licensed Aircraft Engineers Association (ALAEA) told members to carry on checking under the old system.

Qantas and the ALAEA again found themselves in front of the industrial umpire, with a Qantas spokesperson confirming the changes would lead to 30 voluntary redundancies, AAP reported.

This comes after the flag carrier’s recent announcement to shed 500 jobs from the Victorian and Queensland heavy maintenance facility,

Despite the Civil Aviation Safety Authority (CASA) giving approval for the changes to maintenance procedure, ALAEA federal secretary Steve Purvinas said they would battle these concerns with CASA.

"If CASA doesn't listen, we will go to the Transport Minister (Anthony Albanese)," Mr Purvinas said.

Mr Purvinas expressed concern that Qantas' new procedures of pilot-only checks would lead to errors being missed, accusing the airline of turning a blind eye to safety concerns while trying to turn it into a low-cost carrier.

Qantas responded to what they call scaremongering by the union by confirming there was "absolutely no safety risk".
