The four F-1251 nutplate brackets receive one 1/4” nutplate each and will eventually be match drilled and riveted onto the F-1236 step angles. Decided there was no reason the nutplates couldn’t be attached at this time, so they were riveted onto the F-1251 brackets.

Looking for more to do, the F-1213-L&R step floors required having 4 nutplates riveted onto each floor panel. All the nutplates required dimpling and once that was accomplished, the nutplates were riveted in place onto the F-1213 step floors.

The last two components worked on during today’s shop session was the F-1207B baggage bulkhead and the autopilot servo brackets. The F-1207B bulkhead receives four nutplates which must also be dimpled prior to instillation onto it.

Before riveting the F-1207B baggage bulkhead in place, the plans have the builder take a diversion to section 39 if the auto pilot option is being installed, as it is in my case. In section 39, the F-1286A-L&R servo brackets and F-1286B-L&R servo angles which make up the autopilot servo mounting and are riveted onto the F-1207B baggage bulkhead and F-1206 baggage ribs.
Access was good for using the pneumatic squeezer through the lightening holes, so all the rivets used to install the servo brackets onto the F-1207B bulkhead were AN470AD4-4.5 solid rivets in place of LP4-3 pop rivets. An AN470AD4-4 rivet was used on the one remaining bottom F-1207B bulkhead rivet.
The access was also good for riveting the F-1286B servo angles onto the F-1286A brackets using AN470AD4-4 rivets.
