You are taking the **** but I will reply, this time.
From Article 129 of the ANO (Definitions):
‘Annual costs’ in relation to the operation of an aircraft means the best estimate reasonably practicable at the time of a particular flight in respect of the year commencing on the first day of January preceding the date of the flight, of the costs of keeping and maintaining and the indirect costs of operating the aircraft, such costs in either case excluding direct costs and being those actually and necessarily incurred without a view to profit;
‘Direct costs’ means, in respect of a flight, the costs actually and necessarily incurred in connection with that flight without a view to profit but excluding any remuneration payable to the pilot for his services as such;
I can't see that the above separates maintenance costs based on airborne time from maintenance costs based on the calendar. Have you actually ever owned and maintained a plane yourself? If so, you must know about this.
And exactly which part of Article 130 do you think is relevant, and exactly to what?
