Hi guys, I'd appreciate any advice relative to the following:
I have a '46 J3 with an STC'd 0-200 that was installed 15 years ago and I recently damaged the Seninich wood prop that had been installed at the time under a 337. So I'm now trying select a replacement prop.
The issue is that the Univair STC for the 0-200 on the J3 only has one prop called out as approved -- that is the McCauley 1A101/DCM 6944 and Univair says that prop may not even be available anymore. And as I think about it, that may why the former owner put the Seninich W72GK-46 prop on it 15 years ago. That prop has worked fine up until now, even though it was never listed as an approved prop on the airplane to my knowledge.
So my question is:
1. Can I simply buy a replacement Seninich W72GK-46 and legally have my mechanic install it since that is what was previously installed under a 337? Keep in mind that almost assuredly the only prop that IS listed, the McCauley 1A101 DCM 6944 is not available.
2. Any other suggestions would appreciated.
