Inserted sheet metal screws where cabin top overhangs wing. Where holes did not match perfectly with tinnermans in wing root rib I rounded out holes with drill.
While doing above noted rivet and screw hole changes that will be needed when wing root fairings go on.
Installed nuts and tightened down aileron hinge bolts.
Secured yokes in center position and adjusted aileron cross-over cable and left and right aft cables to center bell-cranks. Installed aileron control arms to approximate in-trail positions of ailerons.
Did above while supervising Jane Robens in doing an oil change and spark plug replacement (3) on RV-7.
