Part M is total bureaucratic nonsense.
For a simple SEP aeroplane there is no need for a CAMO to manage the paperwork, or for LAEs & mechanics to service it.
For the last ten years I have done all of that, including annuals & maintenance up to 1000 hrs and 6 year checks. I use a personalised & approved type-specific manufacturers maintenance program which tells me what to do, how to do it, and when to do it. I have subscriptions with the airframe manufacturer, the engine manufacturer, and the propeller manufacturer. They send me the latest SBs and ADs, as do EASA via their AD subscription service. The reason that I as an owner/pilot have been able to do this up til now is that my Robin ATL is French registered. Also no one at my home airfield objects to my working in the hangar. And the local engineering facility are happy to allow me to use calibrated tools and test equipment.
I also service my own car.
