102-33.415—When may we declassify an aircraft and remove it from our Federal aircraft inventory?
When an aircraft is lost or destroyed, or is otherwise non-operational and you want to retain it, you may declassify it and remove it from your Federal aircraft inventory. When you declassify an aircraft, you remove the data plate permanently, and the resulting “aircraft parts or other property” are no longer considered an aircraft. See §§ 102-33.415 through 102-33.420 for rules on declassifying aircraft, and see part 102-36 or 102-37 of this subchapter B on reporting declassified aircraft as excess.
