Drilled the F-714 aft deck to the longerons. Deburred and primed the F-714 aft deck along with the F-710C and F-711E spacers. Riveted the F-709 bulkhead to the aft deck. While this step is called out later on, I saw no reason to wait as this part has no choice in location fore or aft. While fitting the aft deck, I had the F-709 cleco-ed in place so that I could use this part as a reference as well. Minor adjustments in the flanges were done so that it matched up properly on both sides once I had the aft deck positioned.
