Pitts S1S Prop change STC or Mod approval 337

[morristull]

I have a certified Pitts S1S in New Zealand and Ineed a new propellor.
Ideally I would like to fit a wood composite MT186 R 160 4G but I require mod approval, 337, STC or I can apply based on the info that it has been done alreadyon a certified S1S.
Has anyone out there fitted this prop to a factory built S1S and can help me by piggy backing on your approval anddata?


Alternatively, I am in the market for a servicable Sensenich 76EM8-0-60 propellor if anyone has one for sale.
