The original exemption for use of permit aircraft was ORS4 1143 which allowed owners, part owners and their families to learn to fly in permit aircraft they did NOT have to already hold a licence. This ORS was withdrawn in Aug 2016 when the scope for permit aircraft was widened to allow all almost all but ab initio training to take place on permit aircraft. The intent though is STILL that owners, part owners and their families can learn to fly on permit aircraft.
This is what the CAA site says:
This permission does not apply to flight instruction and examination where the recipient does not hold a licence, except when the recipient is:
- The registered owner or joint-owner, or
- A registered shareholder of the company of which owns the aircraft, or
- Is the spouse or child of a registered sole or joint owner.
