I have built a turbine powered CH701 and am having trouble getting the inspection requirements required by the FAA to be approved. I am looking for someone with recent experience.

Thanks

Scott

Scott,

There is no set formula for success on this, but what I've found is that usually if you have inspection criteria for the engine from the engine manufacturer you should be good to go.  If you present a plan to the FAA wherein the engine is inspected in accordance with manufacturer's instructions and the rest of the airframe is inspected in accordance with the scope and detail of appendix D to part 43 you should be OK.

Cheers!

Joe

I did exactly as you suggested but he wants  things like a list of effective pages and written check lists for all inspections. Every time he adds a new requirement it takes a week for him to respond to the change. This has gone on for a month. When I finely get it approved if anyone wants a copy for a starting point for their paperwork just drop me a line

I know virtually nothing about this sort of inspection, but my curiosity is killing me.  What sort of turbine engine have you installed in a CH701?  I can only imagine what it will climb like.

Best of luck.

The turbine is a heavily modified JFS100-13. It puts out 120 hp and 325 FPT. Clime is what it will do best. When i get the inspection i will let you know the rate. If you want a look go to you-tube and type  ehpro in the search block. it will bring up the dino testing and static tests as well as the taxi tests and soon the first flight i  hope.

Scott, Are you having the problem with an FAA Inspector or a DAR?  Just wondering, as this sounds like something the Dallas FSDO would be doing.

Faa/Houston fisdo. I suppose the man is just overloaded but I do not think this should take over 30 days to complete.I have been waiting for 4 days since I sent him my last updated document and no reply yet.

Richard,

The turbine inspection program is required to be approved by a FSDO.  No DAR would have the authority to do this, which is a shame because there are many who would be more than capable.

The problem is, many if not most FSDOs have never had to deal with this and there is NO clear guidance on what they're supposed to be looking for.  What's acceptable for one FSDO is not for another.

Another case of the FAA helping us!!

Cheers!

Joe

Today is a good day. I finely got the FAA approved inspection document from the FAA. It took longer than I expected but it did get dun.The DAR is coming out to look at the plane on Monday 11-20-2010 and then we fly! I would like to thank all those that responded and would add,Don't Waite until your plane is finished to start the turbine paperwork.Start it at least a few months before you finish your project.If you can find a copy of something that has been approved you can base your document on that for a start. I now have one if any of you are going through the same thing.

Thanks

Scott
