Invoice came in today......
Still waiting for mine, but I know that this will be the most expensive annual for me so far. My shop has just got a very knowledgeable Bonanza mechanic who found some stuff others didn't. All legit.
The biggest expense was exhaust repairs and replacing a cracked rib in the right flap (just under the step). It was likely there for many years as a few previous owners were quite big guys... I've also got new tires, new flap motor (I still had an original one from 1967!!), new shimmy damper, new ELT (I had ameriking one affected by AD). The rest was just small things here and there like rigging the gear doors, replacing various gaskets and o-rings, new fuel drains, window seals, etc.
Some of that stuff could wait, but I decided to postpone some upgrades and make it perfect.
So or if all planned upgrades I only put G5 AI and installed Aera 660 in the panel dock replacing my old 396. Hardwired to power, audio, GDL39 3D and my 430W. I did Aera install myself under A&P supervision.
I still plan to install a second G5 later this year and do most of the wiring myself. Decided not to do it now as the plane was sitting in the shop for too long already and they are swamped.
Glad I replaced the flap motor. The old one was noisy and very slow. The new one is a bit quieter and much faster. I was complaining about my flap extension speed for many years now, but I was told that replacing the motor likely won't make it faster. It was taking 20-22 seconds to full extension. Now it takes 12. What a difference.
The bottom line is that it's pretty normal for those of us flying 40-50 year old airplanes. There is always something. You can defer some stuff for later but at some point you'll have to address it.
