Good day all. I am looking for information regarding which specific io550 is needed in order to convert a 200d. Ive found little bits of information here and there such as the conversion does not require an stc but is approved under a 337 but nothing definitive. If it is an stc, who holds it? I find the 337 idea hard to believe, but I’ve certainly been wrong before.
Thanks for any help.Hi Bailey,
Yes, it’s true, for many years the IO-550-F upgrade was indeed done with a 337 field approval. The -F model is actually very similar to the IO-520-A so there’s no changes to the airframe. Just new baffling needed.Today, Lone Mountain Aviation as an STC for this upgrade: https://lonemountainaviation.com/ . Because of this, 337 field approvals are no longer granted. Fortunately, the STC itself isn’t very costly.
The biggest cost in the upgrade is mainly the core up-charge.
Hi Dean,
Thank you for clearing that up for me. We’ve got a mid-time 520 with a long calender time since overhaul and are looking at our options.
Thanks again.How old is the engine and has it been flying much recently? Oil analysis? I recommend Blackstone.
Which Meyers 200 is this?
Hi Dean.
Apologies as I just saw your last reply. The airplane is n5507m, Walt Bowe’s old plane. The logs are away from me right now but I believe the last (only) overhaul was 1978. Weve sent one oil sample off to Blackstone and they gave us some things to watch and get back to them. After I got signed off in it, I flew it about 40 hours in 5 months or so. Prior to that it had been sitting for some time. It is a certainty that we will be changing the engine out in the next year or two, hence my curiosity in the 550.
ThanksThat’s a good plane you got from Walt and I’m sure you’ll enjoy flying it.
Do you have any plans for the spare airframe that came with the sale? I have a friend looking for a project.
