Master and/or MELS are an approved document under commercial AOC ops only. Under PVT ops there is no such thing. Fuel gauge U/S or even nav light blown, aircraft is U/S.
The aircraft shall comply with Type Cert and/or NAA requirements.
As previously posted nobody can find the answer because there isn't one.
You take the option of PVT you are in an unregulated environment over which there is very little control. Hence no MMEL.
If you are of the opinion that you should have or be allowed to have an MEL who would make the decision and control it?
No one is required to have an MEL Operating under part 121, 125, 127, 129, 135, Large (12,500 lbs.), or turbine powered aircraft You may not operate with inoperative equipment without an MEL This means these operations for the most part have to have an MEL
No mention of Part 91!
Read carefully
