Started out by installing the jury struts, drilling to 3/16 and de-burring all sharp edges, then drilled out the main strut attach points to 5/16 and de-burred. Also drilled the the struts where the attach blocks join to the strut and installed 1/4 " bolts and torqued to 70 inch lbs. Flipped the left wing over on the bench and removed the bottom skin, installed the flap mixer and cut out the bottom skin to except the insp'n cover.
