Essex town providing staff for plane, maybe (11)

I believe the answer is:

manningtree

'essex town' is the definition.
(town in Essex)

'providing staff for plane maybe' is the wordplay.
'providing staff' becomes 'manning' (man can mean to staff or operate).
'for' is a charade indicator (letters next to each other).
'plane maybe' becomes 'tree' (plane is a type of tree).
'manning'+'tree'='MANNINGTREE'

I've seen this clue in The Guardian.
