Red tape !
I am still trying to find out if owners intend stay inside the "controled enviroment by taking a contract with a subpart G company to supervise the mantenance of the aircraft and then "shop around" for the maintenance to be done by any company that might be avalable at the time.
OR
Contract both the supervision and the maintenance to one company and do this for three years to stay inside the "controled enviroment".
So far I see a lot of misunderstanding of the system as the CAA intend to apply it in the UK and not a lot of companys yet approved to do any work.
The last time I checked only nine supervision/maintenance approvals under part M had been issued and this with the implimentation date five months away.
