Here goes another can of worms but.. the fact is that the spinner is not listed in the TCDS for any prop/engine combination so it is not required. The spinner is not a fairing that is part of the airframe. It is part of the cooling system and on some aircraft with some combinations of props and engines it is required but none of those combinations apply to the Ercoupe. The spinner came with most Ercoupes from the factory because it was standard equipment with most props. It was standard equipment because Fred liked the looks of the Ercoupe better with the spinner so Erco made it standard. Standard equipment is different than required equipment.
This is my opinion as an A&P, this is also the opinion of every other A&P/IA I know except John Cooper. It is also the opinion of the FSDO here in Cincinnati so I feel OK expressing it. It is not Williams opinion who is not an A&P and I will not participate in a long rat hole again over it so I this is all I will say.
