Yes, you may declassify aircraft (See §§ 102-33.415 and 102-33.420).
(a) A declassified aircraft is no longer considered an aircraft, but may be considered as a group of aircraft parts or other property for ground use only.

You must carry such “aircraft parts or other property” on your property records under the appropriate Federal Supply Classification group(s) (e.g., miscellaneous property).
