Is a Forney 415-C LSA compliant?

There is no LSA compliant Forney aircraft !

The FAA is so messed up they list mine as Engineering & Research 415G, and doing a state search, sometime it shows up, other times it does not. So take the FAA database for what it is, something riddled with errors

Be assured that Forney did not build ANY 415 series Ercoupes. The two tail numbers listed were produced before mine (N99825) and mine was built in 1946- long before Forney existed.

I am using the FAA search engine by make. Searching under make=Mooney, no model 415 shows up in the current registration, under make=Univair only 1 415d appears, but searching under make=ERCO, 7 show up as 415c/cd, and 4 as 415d. I was relying on the articles on EOC, which advise that some models may have been converted from C to CD, D, or even E, which might explain how the make got changed when the aircraft was re-registered. All of these aircraft show an airworthiness date in the 50s, instead of the 40s. I really appreciate all the help you have given. Its quite a complex maze to navigate.

Its beginning to look like 1946 models that bear the name Univair or Forney could have been converted from earlier 415 models, while Univair or Forney held the type certificate. It does look like the only way to go is to trace the actual history via the CD for that aircraft from the FAA.
