Check pins, notice problem (10)
I believe the answer is:
inspection
'check' is the definition.
(to inspect is to check)
'pins notice problem' is the wordplay.
'problem' indicates an anagram.
'pins'+'notice'='pinsnotice'
'pinsnotice' anagrammed gives 'INSPECTION'.
(Other definitions for inspection that I've seen before include "perusal" , "Official examination" , "Check" , "Close examination" .)
