Removing and surrendering the dataplate is a relatively recent development. In the past, nobody cared. Years ago I was in a guys workshop where he had dozens of removed dataplates hanging on the wall. Pretty sure he didn't bother getting permission.Would you contact first for permission to remove the data tag? Has anyone done this?
But what if the aircraft you own wasn't destroyed or scrapped, can you start to do the modifications and turn in the data plate with the exhibition application when it is finished? Might take 10 years to modify.Nonetheless, if an aircraft registered in my name was destroyed or scrapped, I would notify the FSDO that I am removing and surrendering the dataplate along with the other paperwork.
