GM1 ML.A.201(e) Responsibilities
CAA ORS9 Decision No. 1
COMMERCIAL ATO/DTO
According to industry practice, the following are examples of aircraft not considered to be operated by a commercial ATO or a commercial DTO:
(a) Aircraft operated by an organisation holding an ATO certificate or a DTO declaration, created with the aim of promoting aerial sport or leisure aviation, on the conditions that:
(1) the aircraft is operated by the organisation on the basis of ownership or dry lease;
(2) the ATO/DTO is a non-profit organisation; and
(3) whenever non-members of the organisation are involved, such flights represent only a marginal activity of the organisation.
(b) Aircraft operated under Part-NCO by its owner together with an ATO or a DTO flight instructor for the purpose of training, when the contract between the owner and the training organisation and the procedures of the training organisation allow it. The continuing airworthiness of such aircraft remains under the responsibility of the owner, or of the CAMO or CAO contracted by the owner, if the owner has elected to contract a CAMO or CAO in accordance with ML.A.201(f).
(c) Aircraft used for very limited training flights due to the specific configuration of the aircraft and limited need for such flights.
