Filled header tank with approx. 5 gal of 100LL today in prep for my FAA Airworthiness Inspection. Finished verifying what cowling fasteners go in each hole of the engine cowling. Next, I'll install the fasteners with the split rings. A Chapter member stopped by and inspected all the airframe and engine hardware for security. You can never have enough eyes look at the plane! I appreciate it very much.
