The wing leading edge upper removable panels on Falcon 50, 900 and 2000s are installed with differing length screws depending on location (see IPC 57-30-30 on the F50 for example). When the lower leading edge panels are off during your next 4A+ inspection, check with a mirror and a flashlight that the screws on the upper panels are not running through the nut-plates and chaffing into the hydraulic pipes which run down the length of the wing. This can happen at a couple of locations where the nut-plate and hydraulic pipes intersect. If chaffing into the pipe has been noted, see DFJ SRM 51-10-10 for permissible damage and the IPC for correct screw length.
