work out Strut and Door open/close geometry
Hello there.
I have a FB339 and have swaped out the original FB retracts for some Trim retracts.
I have now found out that the geometry for the door that's attached to the strut has changed.
The door and strut now bind when open(hang out).
I think this is because the Trim unit is different in pivot point in height (elevation in relation to where it screws into the bearers)and is offset where the strut fits into the trunion.
How do I work out the geometry so the door closes flush with the wing skin but when opens (hangs out), there is about 5mm gap as original FB setup?
I have atached some pictures for you all to look at.
Thanks for your help, Mario.

Have a look at the gear retraction on this SM MB339. You can get a general idea of the attach points on the door & strut.
