By now I've learned that when I find a problem on one airplane there's a pretty good chance that it exists on other airplanes. This one is very serious, and could potentially cause a catastrophic failure.
I was asked by a friend today to help him find the source of an oil leak on his recently completed RV-10. It looked to me like the gaskets on the magneto covers were leaking (he had dual Lightspeed electronic ignitions with the crank triggers). So I recommended he replace the gaskets, as they were overtightened.
When he removed the covers, both mag drive gears were lying in the holes, and luckily the rubber bumpers were still in them.
It turns out the engine was shipped with mags and they were removed. The aircraft was built at one of the known builder-assist centers.
Please, please, take the time to check yours if you don't know for sure that the drive gears were removed with the mags. This could easily cause a catastrophic failure within the engine.
