Need some help. I recently installed the O-200A engine in my coupe and didn't like the performance of the McCauley 1A101 propeller I had. I tried a 1B90 prop I had and like the performance. I thought I would try and do the right thing and submitted a 337 to the FAA in Salt Lake City FSDO for a field approval. I sent copies of the TSDS for both propellers showing the approval for the props on the O-200A engine and this prop is approved for installation on the C-85 engine in the Ercoupe however I have nothing showing approval for the prop on the O-200A engine in the Ercoupe if I had that I wouldn't need the field approval. They are telling me I will need engneering data to get this approved. A fellow a&p told me today the only difference on these props are the 101 is square tipped and the 90 has the rounded tips, and that I should have just made a log book entry. Does anyone out there with the O-200 installation have the B90 prop on theirs and have any approval for this. This is on a 415D.
