Can anyone give me a simple description of what I call the prop-slack gearbox check for 912 without the slipper clutch?
I have the impression (not sure where I got it) that it involves locking rotation of the engine, put a known torque on the prop and see if there's any prop movement outside of some specified small(?) amount.
Or am a confusing that with the checkup for the 912 with the slipper clutch.... or are they the same, but just with different torques and different allowed slack or slippage?
