RV 10-27

4 March 2020 - Unfortunately, this report is as much about the Cub’s misfortunes as about good progress on the RV-10. First the bad news. After trying to trouble shoot our loss of oil pressure on the Cub, it was finally decided that there was no alternative but to remove and tear down the engine to diagnose the problem. What we found was not good. Somehow a fine grit of unknown origin got into the oil and scoured major internal parts, damaging them beyond repair. The casualties include the crankshaft, camshaft, main bearings, and oil pump. Tom Crone did a great job of measuring everything with precise micrometers to confirm that tolerances had been worn beyond serviceable limits. We are now in the process of negotiating with a shop that specializes in small Continental engines to see what can be done. Meanwhile, the RV-10 project is moving right along. The main focus has been on routing conduits for plumbing and electrical systems and on the air-conditioning system. One major part of the optional air-conditioning system is a large air scoop added to the belly of the plane. The plane was put on its side to work on the scoop which at first glance looks like something from a P-51. The control system is also getting some attention. Links for the rudder cables were fabricated and Richard began work on the control sticks. The next work session will be Saturday, March 7th at 9:00.
