I linked OH-43D 139990 to the old registry N5190Q that was showing, but instead it created a new entry so now there are two for an OH-43D under N5190Q listing. I'm thinking it's because there is a dicrepancy in the number of seats so it show as a different machine. I entered "4" on 139990 because that's what a book I have said, but the original N5190Q entry has "2" Anyway, one of these N5190Q OH-43D entries need to be deleted and the other one linked to 139990.

Hi Glenn,

You didn't do anything wrong.

To explain the reason, I need to make it clear how do we (or the system) distinguish different airframes. Manufacturer, model and construction number are counted in, nothing else. So seats, engine number, etc doesn't matter.

The reason is, before Glenn's linking action, aircraft N5190Q was linked to airframe ID 380303, while aircraft 139990 was linked to airframe ID 621656. Why? Because the c/n are different, one is "139990" (please note this is c/n, not same as aircraft 139990, which is tail number), and the other is "unknown". Glenn's linking action will insert another aircraft record, whose tail number is N5190Q and link to airframe ID 621656 (the one aircraft 139990 use). So now we have two N5190Q, pointing to two different airframes.

I will manually fix it, by removing airframe ID 380303 and coresponding aircraft record. In the future some functions may be created and open to selected members to provide an interface so they can fix the problem.

I hope I explained it clear enough. It IS a bit complicated.

A little to add:

The N5190Q linking to airframe ID 380303 was imported from FAA deregestered records (it has c/n 139990), and aircraft 139990 with link to airframe ID 621656 was entered by our member.

When you enter a new airframe (aka Add new aircraft data - step 1), after typing and choosing manufacturer and model, you should see a list of existing airframes of same model on the right side of screen. If you see the c/n already exists in the list, click on it and choose "Use this airframe".

The new system with more capabilities is hard to learn.
