Aircraft is not condemned as scrap (8)
I believe the answer is:
jettison
'scrap' is the definition.
(I've seen this before)
'aircraft is not condemned' is the wordplay.
'aircraft' becomes 'jet' (jet is a kind of aircraft).
'condemned' indicates an anagram.
'is'+'not'='isnot'
'isnot' is an anagram of 'tison'.
'jet'+'tison'='JETTISON'
'as' is the link.
(Other definitions for jettison that I've seen before include "Deliberately dump overboard" , "21 [OFFLOAD]" , "Ditch (cargo)" , "Throw away (from ship or aeroplane?)" , "Abandon, discard" .)
