About a year ago a factory sheet was posted with numerous torque values, including for the strut/wing attach, stating for 7-series 25 ft-lbs for front strut wing and fuselage attach; and, 25 ft-lbs for the rear strut upper (wing) attach. I wanted to verify if this applied to wood spar 7ECAs of if there was a different spec or it was per AC43.13. For the front strut upper that figure exceeds the AC43.13 max torque for an AN5, so verifying that as well.

Wally the sheet is for metal spar wings not wood spar wings.
Wally use standard torque per AC43.13 for bolt size for the wood spar wings
