Advice after flight training to engineering !

[Big Duke 6]

I have a degree in mechanical engineering, 6 months experience in tech services Ryanair & 100total time flying helicopters.

I'm looking at options to get into maintenance and seeking advice.

Tech services - stuck in an office I didn't like, I much prefer hands on maintenance.
Current job is engineer surveyor lift & crane.

I'm looking at serving a 4 year Ac apprenticeship but at 35 yrs old ill be back day one on 200euros a week..
Not ideal but ill do if no other options..

Any ideas for career ?

Want to end up working in air accident In years to come..
Was going to do Heli piloting but costs are massive..

Any advice really appreciated.
