This past weekend I pulled my RV out of the hangar to do a series of test runs in preparation for the first flight.
The first run-up went well with all indications reading normally.
While waiting for the engine to cool back down for the next run I left the plane out in the sun with the tip-up canopy closed and no canopy cover in place.
After the engine cooled I jumped in and proceeded with my pre-engine check list only to find out the 5A breaker-switch for the fuel pump would not turn on. I suspected it might have overheated in the closed cabin because everything in the cabin was HOT to the touch. (Note: all the remaining breaker-switches functioned normally.)
The engine started without the electric fuel pump and I was able to do my second test run of the day. After completing the test run, I pushed the plane back into the hangar and after cooling off the breaker-switch functioned normally.
I have ordered a replacement breaker-switch and will change this one out.
Here is the question, is this a common mode of failure for these breaker-switches?
[Please do not turn this into another breaker vs. fuse debate, there are enough threads dedicated to this top already and I have made my choice and will stick with it.]
