Bc12d-4-85??

[DannyDot]

I think the model number is BC12D-4-85 that is a T-craft that is sport aviation legal but has a starter motor and an 85 HP motor. Is this correct?

If it is, how often does one come up for sale? I gather they are rare and I should not hold my breath to wait for one.

Been lurking for a while. I recently acquired a project BC12-D. Tim, which O-200 STC are you referring to?

I wouldn't hold my breath waiting to find one. They were only proced in 47 or 48 and very few were made.

The FAA registration list shows only 7 of the over 2000 BC-12D's registered are the -4-85 model. There may have been conversions that didn't get a new type certificate (for example, mine is still registered as a BF model altho the FAA has documents showing a 337 to convert to a BC=65). However, like Tim, many conversions went to a model with a higher gross weight -- especially before the LSA regs.

Dan, your registration should show a BF model, even if someone has installed a 65 Continental. The 65 Continentals is not approved under the BF type certificate, that is why it needed a 337 for approval. If the engine was approved under the type certificate it would have been just a logbook entry. The factory is the only one that can re-certify an airplane under a different type certificate. I went through this in reverse with an airplane that had been incorrectly changed. Tom

Re: Bc12d-4-85??

My airplane was built as a BL, and when they changed it to a Continental they issued a new data plate as a BC. The registration still shows up as a BL, and half of my paperwork sys BL and half says BC. So at one time at least, when you did an engine change they issued a new data plate.

That STC is for installing an O-200 crank, rods, and pistons in a C-85, not installing a O-200 on a Taylorcraft so you are not confused. there is no STC currently available to install a O-200 on a Taylorcraft. I was able to install on with modification of the Harer STC on the DeLuxe we did. Mike Swick has an STC but he will no longer sell it.

Re: Bc12d-4-85??

I got a C90 approved with the Harer STC with a note on the 337. You are allowed up to 10% HP increase at the Field approval level...so 85 HP + 10 % gives a maximum of 93.5 HP. That's why they won't approve an O-200 via 337. Crispy did it though..... Bottom line is....with the Harer STC an upgrade to a C90 is a simple note added to the 337......OR don's dream machine STC upgrades a C85 without legally changing it from a C85 by installing an O200 crank etc and boosting the HP....it's all about paper.

I got it done with the STC and 337 because of converting to model 19 and the F-19 is the same with the exception of the motor per TC data sheet

Thanks for the information. I will not wait for one to come up on the market.

Re: Bc12d-4-85??

Dan, I have a BC12D with full electric and transponder. It was converted to a C-65 many years ago and they called it a C-65-12 in the paperwork. If you need to see the paperwork to help in a conversion I'd make copies and send. This one had minor repairs and is almost ready to fly again. The only thing keeping us out of the air is a rusted strut tube on the right landing gear. Converting to a full electric apparently didn't change this one out of the Light Sport category.
