Another one of those simple tasks that I had been putting off. The cowl access hatch provides a means of successfully getting the top cowl piano hinge wire in and out of position (although I have yet to actually succeed at doing it) and provides access to the dip stick and oil filler spout. I have seen a number of variations of completing this task, some folks using hidden hinges and cool remote control latches, others by the book. I figured that anything but by the book is going to take three times as long as necessary and I am working to meet a first flight time of fall 2013, so from here on no trick stuff unless it really pays off in operation or maintenance. Anyways, this little door took about 6 hours from start to finish. The cam lock fasteners are about 1/8″ too long, so new ones will be stuck on the next aircraft spruce order.
