Notices faulty part (7)

I believe the answer is:

section

'part' is the definition.
(sectioning is a kind of parting)

'notices faulty' is the wordplay.
'faulty' indicates anagramming the letters.
'notices' with letters rearranged gives 'SECTION'.

(Other definitions for section that I've seen before include "unit" , "branch" , "Distinct part" , "Divide; part" , "Department, division" .)

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