Landings in phase 1 of flight test

While I agree 100% what the purpose of this 40 hrs. I don't see in the
regs where is requires the DAR to impose a a limitation to a single
airport.
I see my friend's point that it would be nice to be able to land at an
additional airport within his flight test area.
The flight test period is also the same weather you are testing a new
radical design or your 3rd RV with a lycosaurus.
Considered the difference in time required between the same airplane
with a certified engine or with a certified engine that the DAR will
not consider a certified engine? What additional flight testing are
you planning for those 15 hrs?
Just saying, if the FARs don't prohibit it, it might be nice to be
able to land at an airport in your practice area and get a burger
between flight tests.

How about adopting the attitude that something may drop off, come loose
or go into vibration - and you don't want to be thinking of $100 bergers
at that point? :-)

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...

Right. I think if you were to take one right from the overhaul shop or
new from the box, that is easily the case.
When it comes off an existing experimental, it is not so easy.
Besides, I think the dataplate was removed from the pan to comply with
the letter of the law, so there is no chance of it being considered a
certified engine (even though it has 100% certified parts, and has 300
hrs of proven operation)
