Say one installs a used certified engine and prop out of say.....a Mooney or similar with the original engine data tag, will you be granted a 20 Hr test period?
Any chapter, verse, or precise answers to get this (25hrs) ? I have the same engine, Bill, and a Hartzell, approved, prop.
At the present time, FAA Order 8130.2H has what you are looking for.
Go to 461. Flight Test Areas.
c. Assigned Flight Test Area.
(1)
Page 4-70 says:
"(1) Amateur-built aircraft issued original airworthiness certificates should be limited to operation within an assigned flight test area for a minimum of 25 hours when a type-certificated engine/propeller combination is installed. A minimum of 40 hours is required when a non-type-certificated engine, propeller, or engine/propeller combination is installed. Furthermore, if the type-certificated engine, propeller, or engine/propeller combination installed have been altered in a way that differs from an approved type design in a TCDS, a minimum of 40 hours will be required. "
I can't be the only one with Vans YIO-360-M1B and Hartzell to get a 25 hr phase 1 from the FSDO.
You may well be the only one. The 'Y' is not certified. The FAA or DAR made a mistake.
The FAA is really good at this right?
It appears to be up to the discretion of the inspector what "type certificated" means. I know of a few engines with the 25 hour restriction that were TC'd at the core, but were running aftermarket accessories like ignition, alternators, starters, etc.
Fair enough, but it's a mistake in the users favor (for once), so good for us.

Well Yes & No!
Neither the FAA inspector nor the DAR has the authority to deviate from the rules. Even if a FSDO Inspector makes a mistake, it still doesn't make it OK.
Kind of a moot point anyway, because I've done a flight test series and I don't see how anyone can accomplish a proper and complete data set in 25 hours. I think even 40 hours is a stretch.
I suspect that a lot of E-AB "flight test" is just hour after hour of flying in circles.
Does anyone know how the definition applies to combinations that are certificated under LSA rules (i.e. non-ICAO CofA)?
For instance the Carbon Cub has an approved O-340 and Catto prop with dual electronic ignition. I presume they have a TCDS or equivalent for the factory built LSA versions. Similar considerations could apply to an RV-12 that was built as E-AB.
There is no such thing as a TCDS for Special Light Sport.
Each item (engine, prop., etc.) is approved under under individual ASTM requirements.
Not sure whether the FAA considers that meeting the requirement. Mel might be able to comment whether any guidance has been given to DAR's regarding that.

This. I don't see how it is possible to do a full flight test program in 25 hours. I'm nearly done with my plane and wrote up a full flight test protocol with test cards, etc. That protocol itself is over 100 pages long, and consists of no less than 33 test flights. I don't see how it is even possible to finish that in less than 25 hours. I will be hard pressed to finish it in less than 40.
I'm with Kevin, I just finished my flight testing this summer and 25 hrs isn't even close to enough time! I thought I could have it done in a couple of weeks but it took and about two months and 44hrs.
Most of the problems I have had with EAB aircraft over 50 plus years occurred well after the initial test period.
One of the most important tests is to test to Vne or even slightly above. I suspect this is done well under half the time.
