Hi Bart,

Many Ercoupes are now in the hands of people who appreciate them for their inspired design and honest capability. More and more are being brought up to high cosmetic quality. Most would replace old, corroded or faded placards with new ones where possible.

Unless stamped data is inappropriately changed, why should engine or airframe data plates be presumed "suspect". Just as firearms can be misused, that is no reason to unreasonably restrict their sale to the general public on the basis of their misuse by those who would ignore the law. As to what is "appropriate", since a CD airframe is now apparently deemed Light Sport eligible purely on the basis of whether or not it was ever "properly" converted to a D Model in FAA records, why is a C with a new data plate any harder to verify as to Light Sport eligibility?

While a new dataplate can be installed to mislead, an original dataplate (and paperwork) from another airframe can (and has been) be used to the same effect. It is clearly inappropriate in each and every individual instance in a society where the presumption of innocence is the "norm" to infer or suggest questionable intent either to those who sell replacement nameplates on eBay or elsewhere or those who buy them unless or until there is some evidence to support such suggestion or presumption.

Those who would speak as an Ercoupe "expert" had best put in the time and effort to so qualify. The distinction between personal experience or opinion and fact is one of the very greatest importance when these differ. The "goal", in every case, should be "the truth, the whole truth, and nothing but the truth".

Complicated? Well, in the "real world" where decisions are made, few things are simple. LIFE isn't simple. College (or tech school) teaches students the "rules", but experience teaches the exceptions. The value of the services rendered by a professional is almost always dependent upon their awareness or lack of awareness of the exceptions! In this context, most things that appear simple have been oversimplified to such extent that the "whole truth" is no longer included. The "informed decision" that should in EVERY case be made, insofar as is feasible, is not possible when too much of the puzzle is thus missing.

You mention "a quirk about the ID plate on a true CD". This infers that there is only one type of "factory" CD data plate.

There are those airframes between Serial Numbers 4501 and 4868 (one of which appears not to have been actually produced, licensed or exported) that were originally produced (or modified on the production line before being flown for acceptance as conforming to their Type Certificate) as 415-CDs. My recollection is that the wording on these data plates essentially substitutes "CD" where "C" appears on the 415-C airframe plates.

There are a hundred plus 415-C airframes with serials as low as 3498 that were unsold in dealer hands when the CD model was announced. At the request of those dealers, these were converted by ERCO in the field into the 415-CD model. The etched lettering of name plates of the latter contain the word "modified", and research to date would suggest that the "new" plate was installed as a replacement for (and not a supplement to) the original.

Regards,

William R. Bayne

Exellent Donald,
My case is there is a lot of misinformation, either intentional or intentional, being advertised about Ercoupes.  You are right about getting the CD (compact disk) from the Feds with a given N number's records, or paying I think it is AOPA, about $50 to get a quick reading on the records for a given aircraft usually in a day. Also, recently there have been advertisements for Ercoupe ID plates being sold for a pretty penny and it doesn't pass the smell test either.  I wish we had a clearing house to identify bona fide light sport Ercoupes for everyone to view.  But then there are people who---------- One little correction. About your statement "Red flags should come up if you see an enlarged trim tab" can throw you off because the factory CD's qualirfy as light sports but have the enlarged trim tab.  The CD's were made after the D's were manufactured so they had most of the features of  a D, except for the elevator restriction, and their gross weight limitation is the same as a C.
Jeez this gets complicated.
Maybe I'll mention a quirk about the ID plate on a true CD at a later time.  TMI for now.
Bart
