A part once it's recast (7)

I believe the answer is:

section

'a part' is the definition.
(section is a kind of part)

'once it's recast' is the wordplay.
'recast' indicates anagramming the letters.
'once'+'its'='onceits'
'onceits' is an anagram of 'SECTION'.

(Other definitions for section that I've seen before include "Segment" , "Notices (anag)" , "Divide; part" , "Element" , "branch" .)

I've seen this clue in The Globe and Mail.
