Match drilled and riveted F-804’s for map light nutplates. I decided to use #6 screws instead of 4-40. I could not source 4-40 nutplates. A little extra work to drill and countersink light housings but works just fine.
Traced lines for forward baggage floor access panel.
Added 3 extra layers of fiberglass to back side of filet where nutplates will be installed.
