Rolls Royce TSIO-360

[Dr.Dan]

Hi guys, I have a major paperwork problem with my newly acquired T337G. The front engine is a Rolls Royce TSIO-360-D. I was told that this was licensed by Continental and made by RR.
Now, according to Continental, they do not hold the type certificate for the Rolls Royce TSIO-360 and thus cannot determine equivalency.
So even though this engine has been installed and working for decades, Transport Canada says it needs to be replaced.

Do you guys have any information about the certification of these engines when they were installed? Based on a search of this forum it seems there are at least a few other P337's out there with the RR engines.

Thanks,
DD
