Clecoed on F976 skin. Riveted skin to F-916 ribs. Clecoed in seat and baggage skins after clecoing in the baggage ribs. Drilled all holes. Fluted left F-915 outer seat ribs as directed. Drilled holes to bulkhead and to bottom skin and seat skins. Spent a lot of time looking at the drawings and was confused a lot with this part so made very slow progress today.
