Rolls Royce TSIO-360

[california Sky]

I have the RR engines in my P model 1973...

I’ll look through my logs to see how they did it and report back.

It’s been awhile since I looked at how they did it for 58C.

Hopefully I have something that will help you.

That would be greatly appreciated!

Thanks

Dan - FWIW, I think you need to have it in writing from them why they will not accept the engine. Check what your IPC says for P/N, then compare with the P/N on the engine. I know with my 337A it calls for an IO-360C, and that is the P/N on the motor. I would also call Cessna next - they may have a Service Letter or SB that allows for this engine (RR) on the aircraft. Don't remove based on some Transport Canada Weeny (I can call them that cause both my brothers are Transport Canada Weenies and they call themselves that!).

Don't worry about Continental - the TC holder of the airframe (Textron/Cessna) is the one you need to coordinate with.

Frank:

The certification authority for the RR engines was the CAA (Civil Aviation Authority) from the UK.

Register it in Canada - Problem solved.

Actually that’s the problem. It has been fine for the decades it has been in the states. Importing it to Canada last year started this fiasco. We are still working with Transport Canada and the FAA. No solution yet.

can you just leave it registered in the US? Plenty of aircraft are registered owned by "holding companies" not necessarily geographically located where you, the individual, is at.

I'm truly sorry for your situation, and I hope you're able to get it worked out.

The FAA CLEARLY stated in the VAR crank AD comment response section that US-certified AC were currently flying with the UK-certified RR engine, AND THEREFORE the AD must apply to them as well.

So if I understand this, the FAA will allow RR engines (at least theoretically based on their own commentary), but CAA will not???

So maybe maintain the N# registration? There are literally thousands of aircraft around the world that will never see US airspace yet proudly sport N# registration.

Seems crazy that the CAA won't accept RR certification from the UK, which is their controlling country. What they are are saying is because your plane was not built in France, it may not have a RR engine, even though both the airframe and engines were certified as identical. An interesting thing to research: Do they allow Continental engines on Reims aircraft??? My guess is they might.

This whole sorry saga is the definition of bureaucratic madness and ineffiency. The RR engines should be looked at as equivalent to the Continentals, and that should be that.

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.
