Prop/my phase 1
I had same issue, and used the local GSO FSDO for my inspection. I also have a Sterba, and used a certified engine I built up (Im an AP/IA). The inspector tried every angle, and by the regulations it must be a certified engine AND propellor to get in the 25hr. phase 1. I have heard others were waived, but I am just going by what regs and FAA follows. Im not sure about VANS props, but it really wasnt a big deal to do the 40 hrs. I am now looking at changing my prop again, as I am under-proped for top end. This will require going back to phase 1 and a call to my local FSDO(no reinspection),in which they will require a period (maybe 5 hrs) before going back to phase 2.
