If it were easy it would have been done long ago. Truth is not something established democratically. It is what it is. The spinner may be considered part of the engine, as opposed to the airframe (and respective Logs); but, either way it was part of each Ercoupe as it was officially signed off as airworthy before ERCO could sell it. I don't want a mechanic that believes the four or eight pages of text (the TCDS) lists all specific requirements of a safe and airworthy Ercoupe. This is the comfort of ostriches with heads in sand (if they really do that). Similarly, it is aircraft owners and operators who "pay the price" when their certified mechanics take such "shortcuts" and they a ramp check grounds them on a trip or metal is bent and records reviewed with a 20-20 hindsight microscope. As an example, appropriate torques that are Ercoupe-specific are scattered throughout the Service Manuals for the whole series. These manuals are not part of or referenced by the TCDS. They are not CAA-FAA approved. Torques and other specific information in them as well as the Bulletins and Memoranda are ignored by mechanics at the owner's peril. The FARs are clear that the operator of an aircraft bears primary responsibility that it be airworthy before operation whether he/she understands that or not. This issue is, therefore, independent of being or not being a mechanic. Sensenich props, original on the Ercoupe did not come with a spinner. McCauley props, original on Forneys, Alons and M10s did not come with a spinner. Ercoupe spinners were manufactured by ERCO. Their part number is ERCO's. Whenever cooling tests were performed by ERCO for the CAA/FAA, a spinner was fitted. Accordingly, associated approvals remain contingent on the presence of the same type of spinner. There is no record whatsoever that appearance was ever a factor in Fred Weick's incorporation of a spinner into the Ercoupe design. Once he did, and an Ercoupe was certificated with that spinner it ceases to be in compliance with it's type certificate when the spinner is removed (presuming removal to be a "major modification"). While I agree that "standard equipment" and "optional equipment" are different, the obvious implication is that "standard equipment" is synonymous with "required equipment". Even "optional equipment" placed on the aircraft Equipment List requires appropriate notations in pertinent Logs and Weight and Balance records when removed, relocated or replaced. To the best of my knowledge I have never stated or implied to anyone on these lists at any time that I am an A&P or certificated mechanic of any kind. I'm not. That said, if I see a certificated mechanic attempting to taxi an aircraft that is still tied down, I will warn him. I will also steadfastly defend until hell freezes over a mechanic's right to ignore my warning ;<) Regards, William R. Bayne .____|-(o)-|____.
