I remember when Sensenich first brought out the C152 propeller it was only STC'd for Cessna 152s not Reims-Cessna F152s and, IIRC not Aerobats. The Reims problem took sometime for them to get sussed.
I know of one operator who operated a mixed fleets of C152, A152, F152 and FA152. If a Reims machine needed a new prop they had to take a McCauley off an American built machine, put that on the Reims and then fit the Sensenich to the American aircraft!
Even stranger was that when McCauley broke the 152 prop blank for making new ones and gave up making 152 props, if you ordered a new McCauley prop (by McCauley part number) through Cessna, a Sensenich turned up on your doorstep!
PS After seeing the Cirrus Twin on the EAE approval when I was getting aggro from my surveyor about what types (models etc) could go on our approval, I requested he allow us to put on Captain Scarlets' Angel Interceptors as I reckon there was better chance of finding maintenance data for those than a Cirrus Twin......
