Looking through the paperwork that I have from 78C, it appears that there is a way to actually certify the RR TSIO 360's for use on US registered aircraft.

On 9-18-1989, Continental issued a Service Bulletin (M89-20) titled Conversion of Rolls Royce Engines. The SB describes how the RR nameplates can be replaced by Continental nameplates.

While the Bulletin was rescinded on 12-15-1989 due to FAA objections outlined in a letter signed by the Manager of the Engine Directorate New England Region, the issue was brought to the attention of FAA national shortly thereafter. On July 6 1990, the FAA (AIR-1 Director of Aircraft Certification) issued an Action Notice (A8110.21) titled Acceptance Procedures for Rolls Royce/Continental Model TSIO 360 Series Engines.

The AN explains how the engines can be approved on an engine by engine basis: provide the initial UK CAA Approved Certification/Dispatch Instruction" which was issued with each new engine and then have the engine inspected by an IA or a Repair Station which can then sign the installation off.

Overall, there were 40 RR engines imported into the US.

So the AN provides a path of a RR engine to be approved in the US. That still leaves Canada.

The US and Transport Canada have reciprocal certification agreements in place and a particular engine approved by the US FAA should be allowed by Transport Canada on the basis of reciprocity.

Hopefully this is helpful. I am happy to provide copies of that documentation if interested.

The Type Certificates for most of the Reims-produced Cessna aircraft were transferred to Cessna in 2006. This allowed owners of Reims Cessnas to register their aircraft on the U.S. N-number registry with minimal difficulty. In the eyes of the FAA, Reims Cessnas are “considered domestic products for the purpose of design certification and continued airworthiness” per Type Certificate A23EU.

Thanks for the post. It is my understanding that if approved by FAA, then yes Transport Canada would also approve. It seems getting official FAA approval has been part of the challenge. Perhaps these documents would help. If you could please forward them to me that would be great. If you send me a private message I'd be happy to supply my email.
However, this avenue may have already been tried by people working on my behalf. There have been nuances in the logistics/paperwork that have killed every possible lead so far.

Thanks,
DD

Guys,

Be sure not to show them a copy of Type Certificate Data Sheet A23EU that I posted links to a couple of messages ago, or they might go, "Oh No problem here. Have a nice day." Then you would have to find another dead horse to beat.

I guess I don’t understand exactly what that a23eu means. Trust me, I’m open to any solution. So far I’ve found that just because it’s logical, doesn’t mean it’s acceptable. I will happily research this avenue more.

The TCDS lists the parameters and equipment for a type certification. I have attached the top part of the TCDS for the French built 337's.

This does not help. The TCDS for the FT337GP lists the Continental TSIO 360C. See the second attachment.

In fact, no French built 337 was equipped with the RR engines when they came out. They were equipped with Continental engines. All Reims did was assemble kits supplied by Cessna under the Cessna TCDS which has always listed the Continental engines.
