Crankcase pressure

Hi folks,

I have come across a report on a Rotax equipped Katana which concluded that a vital engine failure was caused by too high pressure in the crankcase. Allegedly this was caused by metal springs in the oil tubes which was meant to hinder oil tubes to collapse in bends. The report says that crankcase pressure must not exceed 0,3 bar above ambient pressure.

Has anyone ever considered to monitor crankcase pressure during flight or on the ground? I have never heard or read about such a function in EMS.

I am far from thinking that one needs to measure this just because it‘s possible to measure it. However, is there any experience with this matter? I am being curious.

Regards

Peter
