Plans for Five Hour Phase 1 with new prop?

[rv7charlie]

I hope this isn't construed as splitting hairs, but I question Mel's blanket statement that simply changing a prop requires a return to phase 1. Unless the regs have changed, my understanding is that only a change of *type* (ex: fixed>c/s) triggers the requirement for phase 1.

Please correct me if I'm wrong.

Any prop change requires a new phase I flight test program, unless it is the same diameter and pitch from the same manufacturer.
A major change is pretty much anything that will change the flight characteristics of the aircraft.

The difference of changing F/P to or from C/S requires that you submit a new 8130-6. This is to change the records in Oklahoma City.

The LAA in the UK specify this test schedule for newly installed CS props.

You may want to use it as a basis for your testing.
