Door frame corrosion

New Bonanza owner, here. Looking for guidance on repairing corrosion around the door. Two places in particular, photos attached. Advice for repairing and sourcing parts would be greatly appreciated. Many thanks!

Robert, the better salvage yards should have these parts. Use the source list here on the web-site. May I ask if you have found evidence of corrosion elsewhere on the aircraft?

Thanks, Steve. The annual was done in May of '23, the pre-buy was done in October. Neither mentioned the corrosion around the door frame. I have the aircraft in a shop now for instrument work. The attitude indicator and altimeter are getting replaced. The mechanics noticed the door frame corrosion. I am embarrassed to admit I never saw it. I guess I was blinded by the excitement of owning this beautiful Beech.
This shop does not do much Bonanza work. They are aware of corrosion issues with the V-tail. That being said I don't have a lot of confidence they know what to look for regarding corrosion. My plan was to take it to Poplar Grove for the annual.
I assume the source list you are referring to is in the classifieds? If not, could you kindly point me to the correct area?
Many thanks for your reply.
Bob

Steve, I realized I didn't clearly answer your questions about other areas of corrosion. The door frame corrosion is obvious. I have not asked them to assess the rest of the aircraft. I would rather have a shop that knows these V-tails look it over at the May 2023 annual. There are no other obvious corrosion issues. I will let you know what comes up at the annual.

Robert, on the drop down menu at the top of this page, select the maintenance tab. Scroll down and you will see a link for “aircraft technical information”. Click on that and there will be a great list of parts and service providers. That corrosion on your door frame has advanced to the stage we call “exfoliation corrosion”. That means it has been there for quite some time. I recommend you and your current maintenance provider start digging around prior to a May annual. The sooner you catch this stuff, the safer and easier it is to correct.

Robert,
I had a bit of corrosion on my ruddervators that I didn't know about. I had taken my V35A to one of the ABS Service Clinics to get an evaluation a few months before my annual was due. It was there that the legend, Bob Ripley, took the time to carefully inspect my plane. He pointed out the ruddervator corrosion to me (among other things), and I must admit that I REALLY had to look hard to see it. I had to get the light on it at a certain angle or it was practically invisible. Be sure to get a shop that knows what to look for. I also had a cracked nose rib in my right flap, which Bob found. At the time, I didn't even know what a nose rib was. The Service Clinic was well worth the money. And for now, all is well.
