To quote what you said in the recent "Urgent -Woodvale" thread on the private forum, when you were replying to a question by someone asking what types you fly:
Professionally I have a history of making flying machines of any size up to 4 engine jet "do stuff".
Perhaps thats the clue - the LAA Coach scheme looks for people with experience on relevant types of aircraft, LAA Aircraft, SEP rather than 4 engined jets or microlights.
I would think that you would be able to offer something once you have ticked the 1000 hours SEP box.
