Newsletter - Lift Strut Detach
Posted: Sat Apr 17, 2021 7:54 pm
I'm curious about the article in the recent newsletter in which a lift strut detached from the fuselage. Does anyone know if this was a one piece or 3 piece wing?
Obviously the one piece wing would be at an advantage in this situation. In the case of a 3 piece wing apparently the force that the strut should have been carrying was instead carried by the cross wire between the lift struts that runs from the forward spar down and aft to the rear strut to fuse attach point.
I'm also surprised that in final assembly the plane "rigged out" nicely unless the lift strut was originally built 1/2" short. Otherwise it seems the 1/2" "too long" lift strut would have made it hard to avoid the plane having "wash in" on that wing.
In any case, a very happy landing for sure!
