Be interested to find out how much your numbers improve. Keep us posted eh...

Be sure and have either a DAR or the FAA FSDO do an approval of the prop change. It is my understanding that the airplane has to go back to Phase I flight testing after either a prop or engine change.

Both Russ and James could be correct...but that depends on what your operating limitations say. I switched from FP to C/S prop in 2005. My operating limitations (dated June 2000) did not allow me to do what James described as the verbage allowing this was not included.The plane has to be put back into "Phase 1" for at least 5 hours of testing in the new configuration after a "major modification" (Prop change is considered major). After discovery of no adverse operating conditions, it is then put back into "Phase II".

I contacted the local FSDO and their response was to issue me new operating limitations. The new limitations had the verbage to allow me to remove my fixed pitch prop, install the constant speed prop then put the plane back into Phase I for at least 5 hours flight testing (all done with complete annotations in the log books).
All FSDO contact was done via phone and snail-mail as I had to send in a copy of the limitations issued to me Rosie
BTW..Born and raised in Centreville Va. Understand it's a little bigger now!!

Mel, my (new) limitations dated February 2005 do not have any of the above wording in them.Even with the latest operating limitations, you must "notify the geographically responsible FSDO of the location of the proposed test area. The aircrat owner must obtain concurrence from the FSDO as to the suitability of the proposed test area. If the major change includes installing a different type of engine (reciprocating to turbine) or a change of a fixed pitch from or to a controllable propeller, the aircraft owner must fill out a revised form 8130-6 to update the aircraft's file in the FAA registry."
For a short time (around 2002), operating imitations were issued without this requirement.
