My A&P and I are in the process of doing the annual inspection on my pretty stock RV-8 (not built by me). So far we have found very few issues:
1) one exhaust bracket needed to be replaced
2) the manifold pressure sensor line was loose
3) one cylinder intake manifold was slightly loose
4) the throttle cable was out of adjustment (couldn't open the throttle to WOT)
5) the EGT probe on cylinder #4 was intermittently not giving a reading
6) the oil cooler cover was too big giving too high oil temps in the summer
The two more difficult problems we found (that I would like suggestions and comments on):
The Van's stock carbuerator heat box was fatigue broken when it mounts to the top of the air inlet scoop. The small manufactured fitting where the SCAT hose connects at the bottom was completely broken. Carb heat has never worked at all (no RPM drop on test) so I am ready to consider another type of carb heat set up (after market or someone's home design). Any suggestions? This is for a Lyc O-360A1A with the precision airmotive carb.
My prop leaks grease. It is a Hartzell C/S with 350 hours on it. It has been this way for about a year. I have asked several people about it and got the common "oh, they all leak like that". My A&P who is very, very experienced says the size of this leak is not normal and I need to get it looked at by a prop shop. The leak in on one blade only and it can put a nice slimey coat on the back of the blade after only a couple of hours. Thoughts, comments?
All thoughts and guidance appreciated.
