The Ercoupe was and is certified under CAR 4a. Can you find similar words in the CAR? I argue that the FAA specifies (today) that the Ercoupe is regulated by the CAR 3 and 4a. There must be a reason that they (FAA) continue to site CAR for most old aircraft like the Ercoupe, Luscombe, Taylorcraft, and the early Cessna's.

Title 14 CFR ยง 21.303(a) requires any person producing replacement or modification parts for sale for installation on a type-certificated product to PMA. Also PMA may approve the production of parts from a supplemental type certificate (STC). PMA applies to most replacement and modification parts. Only use an STC for the approval of parts that constitute a major change to the product. See FAA Order 8110.4, Type Certification, for STC procedures. > > > b. Getting a PMA for Technical Standard Order (TSO) Articles. We at the FAA may issue a PMA for replacement parts for articles produced under a TSO authorization when these articles are in the product's type design. Then the replacement part is for the eligible product not the article. The installation of a PMA part may result in a minor design change TSO article yet meet the product's airworthiness requirements. We may require the installer this part to place a modifier's nameplate on the article. See FAA Order 8150.1, Technical Standard Order Program, for more details. Replacement parts approved under the basis of identicality do not change the article's design and do not require a modifier's nameplate. > > Full text: > > > > http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgOrders.nsf/0/d134 929f93b3334e8625708100582c1b/$FILE/Order%208110-42B.pdf > > Even if the ADI is STCd, They must have a PMA to manufacture it for certified aircraft. > > > We are stumbling over words.
