Stats about fine retired plane (6)
I believe the answer is:
dakota
'plane' is the definition.
(I've seen this before)
'stats about fine retired' is the wordplay.
'stats' becomes 'data' (I've seen this before).
'about' means one lot of letters goes inside another.
'fine' becomes 'ok' (synonyms).
'retired' says the letters should be written backwards.
'ok' in reverse letter order is 'ko'.
'data' placed around 'ko' is 'DAKOTA'.
(Other definitions for dakota that I've seen before include "Stereophonics single / John Wayne film" , "US territory split North and South" , "North American Indian; Douglas DC-3" , "Douglas DC 3 name; N. American native" , "North American native; Douglas DC 3" .)
