Looking for a DER (Designated Engineering Representative) for Ercoupe

you don't need a DER to figure electrical loads, you need a mechanic that knows how to read 43.13, and CAM 18

Kerry;
Suggestion, ask what your A&P has a problem with that will require a DER ($$$$). As simple as most electrical systems in Ercoupes, see if you can post the problem here - loads of tech help here at no cost. Possibly a phone discussion with one of the experienced mechanics can solve the issue. FWIW 2c

My A&P is asking if I know of a DER who is familiar with Ercoupes.  He is working on my plane and says we need one to calculate electrical loads.

Does anyone have experience with a DER who understands Ercoupes?
