All of the seats come out, then the back bulkhead covers. You have to drill out a bunch of nutplates along the tunnel and aft end of the floor. Even the side covers have to come out. I managed to leave the flaps attached, but the plastic blocks that hold the weldment for the flap arms had to come out. I bought a nifty pop rivet removal drill accessory. Once I got it all dialed in for the correct depth, it was pretty easy to drill out all of the pop rivets on the baggage floor. I have a similar attachment for drilling out the regular rivets on the outside flange of the steps. I had put some proseal under the step flange and that was a real bear to free up once I got the rivets all removed. I was able to slowly wedge up the flange and then I used my thin metal ruler to separate the rest of the proseal. I had bought some "poly-gone" goo which removes proseal, and it worked very well. Today, I got out to the hangar and cleaned up the rest of the primer off of the steps. My old hangar across the field has a sand blasting cabinet that I used to fully blast off all of the old paint and proseal on the step weldments. I can't wait to get these fixed, and back on the airplane. I guess I'll start my "annual" this week, since the plane is already mostly torn apart.

Passenger side done.

Rivets on the step flange all drilled out.

Proseal under here. What was I thinking?

Pilot side done.
