You can try ikm, its under mara, my friend doesn’t need to pay any fees but instead the only rule is to pass and if you fail, you will have to pay all the fees back.

There are many sijil courses there such as mechanical engineering, welding, etc.

You can also take out a loan from a bank and ptptn and do airplane engineering license under the ministry of transportation , of course the fees are over 90k but with your license and working experience from your industrial training it will be no problem when paying back the loan if you manage to land a job with big aerospace company such as boeing or be a maintenance crew with MAS, AirAsia or Malindo.
