Remove fuselage side panels for inspection and wiring. Several screws were inaccessible and others were VERY tight. One screw, in the left side forward corner, broke and required drilling. I decided to drill the rivets holding the plate nut as they were aluminum and more accessible. I need to replace that plate nut. A couple of other screws needed to be slotted in order to get sufficient torque to loosen them..
After removing all screws, panels were slid upward, then downward to remove.
