westcoastoz Posted May 19, 2011 Report Posted May 19, 2011 I am just in the process of getting all the required parts together for the 912ULS 5 year Rotax rubber replacement and am wondering if anyone knows what FD have used for the induction manifold ducting? It sure looks like 3" CEET duct (#05-30512) however my A&P has questioned it's suitability for negative pressure situations such as induction to a carby. I have attached the duct manufacturers information sheet:-
westcoastoz Posted May 19, 2011 Author Report Posted May 19, 2011 OK thanks Roger. Does the CEET duct have a lining inside or is it rippled? I think there may have been problems in the past with the SCEET (red duct) as the lining has separated under negative pressure and caused obstruction to the airflow. Hopefully I can source some CEET locally as I am running out of time fast. Regards, Dave
207WF Posted June 27, 2011 Report Posted June 27, 2011 We had to replace the factory original (black) ducting on mine with a better (orange) version. The black was flaking off into the carb. and I made one "interesting" landing with fuel smells in the cockpit and a rough running engine that seems to have been caused by this. WF
