So it appears it is still a proposal BUT where does the LAME maintenance proposal come from? If you can’t work that out then I can’t help you, it is as plain as the nose on your face.
Commensence tells you 100 or 150 kg changes nothing in the maintenance procedure BUT this restriction is being put forward by what was once called to be “our” organisation - no longer the case.
i.e. A L1 can maintain the same aircraft but a L2 is now deemed incompetent - I wonder who would make such a ridiculous proposal - I’ll leave it there.
