Default Test Flight Time 25 vs 40 Hour

How do I provide documentation to have my test flight time reduced? How do I find the type certificate for engine and prop? I assume there is a document that makes this easy. I am preparing for my DAR inspection. I have an RV-14A with the O-390 and hartzel prop, standard stuff.

I believe if you have an engine/prop combination that is on a certified aircraft then you are eligible for 25 hours. Its going to come down to whatever your DAR is comfortable with and what documents he wants to see.

What engine and prop do you have? The TC's should be documented in the respective logbooks. The TC is also listed on the data plate.

You’ll need to search for the FAA TCDS for the EXACT engine and prop model numbers (with all the prefixes and suffixes) and then determine if they have been certified as a combination or not. My guess is that if they are just the “normal” configuration that Van’s sells, then it is experimental and you’ll have no way to justify 25 hours. The rules are very specific, and DAR’s don't have discretion to break or bend them.

The engine on our little jet is actually certified in Europe, and my FAA Inspector really wanted to get me a 25 hour Phase 1 - but alas, the paperwork was never done to copy the certification to the U.S., so we coulnd’t do it.

The truth is, a thorough flight test program will take more than 25 hours - closer to 40 - anyway.

Like Paul said, not a heck of a difference between the 25 vs. 40 hour Phase I. More importantly is getting the DAR to allow a liberal flight test area that will allow you to fly the machine in real world conditions, not boring holes in a 25nm radius.

This is interesting. The FAA TCDS P-920 covers the Hartzell HC-C2YR-1BFP/F7497(-2), but the (I)O-390 is not one of the engines listed in the document at all. See Note 9, Special Limits, for approved combinations of hub/blade/engine.

In any event, since Van's only sells "Experimental" Lycoming engines (i.e., X or Y(I)O-XXX), would they be eligible for the 25 hour Phase 1 test period at all? I think not.

I have the "stock" Van's engine and prop, Lycoming YIO-360-M1B and Hartzell HC-C2YR-1BFP/7497, and got 25 hours, no problemo.

Your Operating Limitations were issued improperly. The YIO-360-M1B is an "Experimental" engine.
