Glenn.
I have added the cn as you requested but have not yet linked the two.
Linkage results in the make, model and cn being identical.
In this case, there is a difference in model description and also the engine specs are at variance. Were I to link them, I would have to retain the FAA description.
The other choice would be to add cross reference notes to both without linkage.
This could be preferable where the FAA listing may not be in compliance with hisorical data, i.e. wrong!
Comments?
