Riveted the bell crank rib assembly together then installed into the bottom skin. Completed steps 1-2 on page 10-21 and started step 3, riveting to the bottom skin. Owen came out and helped me finish this run of rivets. Also installed 4 of the six AD470 4-4 rivets into the bulkhead. Will need to crawl back into the tail cone to get the last (bottom) two.
