You can drop down to the Private Cat maintenance, unless there is
a) renting, or
b) training for the initial award of any license or a rating (except for a 100% owner which is permitted, or the training is done by an instructor who is doing it for free which is also OK), or
c) an owner owning less than 5%, or
d) any use that requires Transport CofA maintenance.
Hope I got that right
