It does, to a degree, but once the OR is latched OR5 shouldn't move
. It would appear the slot was designed for a 30deg max flap
setting which is too much as you run out of aileron authority, it
was reduced to 26 / 27 but new OR5's weren't sent out as it seems
to work OK. (A stiffer spring was sent out though to everyone
below about kit 50, we're 47 and I think it was the first mod we
ever got) it was standard after that.
I am making new OR5's to get an idiotproof latching at 26.5deg.

The slot needs, in fact must, be only slightly shorter, about 2 - 3
mm. otherwise the flaps will lock at OR latching position (c. 20
deg) and not where they are supposed to be.
