Flier eating chop and banger (6)
I believe the answer is:
jalopy
'banger' is the definition.
(jalopy is a kind of automobile)
'flier eating chop' is the wordplay.
'flier' becomes 'jay' (jay is a kind of birdanimal**).
'eating' is an insertion indicator.
'chop' becomes 'lop' (I've seen this in other clues).
'jay' placed around 'lop' is 'JALOPY'.
'and' acts as a link.
(Other definitions for jalopy that I've seen before include "Rundown old car" , "Old vehicle" , "Ramshackle old car" , "A battered old car" , "heap" .)
