I have an older E-mag (but not p mag). It specifies inspections at 100 hrs. That means removing the unit from the accessory case, inspecting its gear and shaft, re-installing and timing. On my plane, an RV-9A, this is very difficult due to the very confined space. At this moment, I’m not even sure it’s possible, get back on if I managed to get it off. Probably a gasket is involved too. This is at annual condition inspection and at about 125 hrs TTSN on engine (an O-360). It’s working fine now. My question is whether this is really necessary. Slick mags don’t have to be inspected until 500 hrs. Why does this E-mag have such a short inspection period? I don’t think any other major accessory has that short a period.
