Americans enquire into managed school by northeast pass (10)

'americans' is the definition.
(Nebraskan is an example)

'enquire into managed school by northeast pass' is the wordplay.
I cannot really see how this works, but
'enquire' could be 'ask' (synonyms) and 'ask' is found in the answer.
'managed' could be 'ran' (I've seen this in another clue) and 'ran' is present in the remaining letters.
'school' could be 's' and 's' is found within the answer.
'northeast' could be 'ne' (abbreviation) and 'ne' is found in the answer.
A single letter 'b' remains which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?
