The flight test period is also the same weather you are testing a new
radical design or your 3rd RV with a lycosaurus.

Not so. If you are using an engine and propeller combination that was
certified in any certified aircraft the flight test may be, and probably
will be, reduced to 25 hours.


I don't know how the DARs do it, but in the old days when the FAA did
inspections they could set any restrictions they wanted.

Including things like time of flight - 6:00AM to 6:01AM.
It all depended on how they felt about the design, workmanship, and
pilot capabilities.

One story goes that it was the FAA reps that vetoed John Dyke's intent
to use foam cored fiberglass for primary structure in the Dyke Delta.
To radical for the times.

Remember, any particular DAR is NOT obliged to approve your project.

For what it's worth...
