Removed the false wooden spars that have been bolted to the fuselage for three years.
Marked the outline of the aft stick-well cover plate onto the floorboards, then removed the cover and all floorboards. Re-assembled the plate and floorboards on the workbench, then trimmed about an inch off the aft edge of the cover plate to allow future access to the floor screws. Back-drilled two holes from floorboards into the cover plate, then drilled them out to #8 and dimpled them. (The two screws that go here will be the only two that go though both the floor and the new cover plate.) The cover plate will also be attached with the screws that attach the vent. I marked the possible future location of the holes that will attach the stick boot to the ring, although I won't drill these until I receive the stick boots.
Finally, I cut notches in the aft baggage wall that will allow the wire plug and harness of the Digital Video Recorder to pass through. This large notch will be covered with a 2"x3" cover plate with a smaller notch and anti-chafe protection. I'll fabricate this plate later. [Superseded.]
