Hello,
It would be pretty interesting to be able to make a complete maintenance hub where you’re able to accept contracts to maintain, upgrade, store and repair aircraft.
It’d be similar to EASA’s Part-145 - Maintenance organisation approvals.
EASA’s website
I’m aware that this is quite a big thing so maybe a simplified version where you’d have a hangar and some contracts and would have to hire people with Part-66 aircraft maintenance licence certifactions.
Maybe add in a depot where you could store parts and have the parts be delivered by manufacturer which you’d have to sign a contracts with and have it be delivered like how building equipment is delivered.
Another thing you could do is sign a contract with a part-145 certified company and let them rent your hangars.
You could use Fokker Aircraft Services as an example.
