I am not sure if this question has been answered before on this forum; if so, I apologize for repeating it.

I was wondering, in a strut based airplane like a Fisher 202 or 303, what kinds of loads are exerted / borne at :


  • the main spar to fuselage metal attachment (wing root attachment),
  • and the strut to spar attachment (where front strut meets the main spar.)

I was specifically interested in knowing how the fuselages's weight is carried / lifted in flight (?)
Some part of the weight, I guess is lifted by the struts (although the strut's primary job is to reduce / eliminate bending loads at wing root and have a lighter structure / spar), and some part of the weight is borne / lifted by the wing root metal attachment.

Also does the wing root attachment/ bracket carry any shear loads at all ?

Thanks for any insight on this.
