|Annual inspection in progress.
This week, I brought my plane in for it's annual inspection. During an annual inspection the aircraft seats and carpeting are removed and the engine, along with all of the access points, are opened up. The entire inspection process can take five to ten days.
Today, I dropped by the shop to check on the progress and the mechanics showed me what was causing the burning smell. It turns out, even though my plane was only outside overnight, that birds had started to make a nest inside my engine --- way in the back of the engine near the firewall.

The bird's nest in my engine could, in theory, present a fire hazard. So, it looks like it's time to buy some cowl plugs to cover the front of the engine. The mechanics gave me a good tip when parking outside: turn my prop straight up and down, instead of horizontal, so birds can't perch on it.
I can only hope to keep learning things the forgivable way.
