This log entry is actually a few hours of work over 3 days. Basically, I've now finished all steps on the left flap that I had previously done to the right flap. This means that I've finished flush riveting the row shared by the nose skin and the top skin, and all of the top skin ribs except for the trailing two rows. The next step would be on page 21-09 to finish the trailing two rows and then rivet on the bottom skin, but I don't want to do any of that until I receive the backordered VA-140 trailing edge extrusion. What's next? I will set both of these partially completed flaps aside and start on another section. I've not heard any word back from Van's Aircraft yet about when to expect the remaining parts, but my order status page still shows that they know I have backordered parts. However, I won't have any time over the next week for plane building since I'll be attending a work event.
