The FAA TCDS for the ERJ 170 includes the -100SE; -100SUand -200SU, but the only differences are restrictions in the maximum number of passengers. This is because of the scope clauses that many airlines in the US have in the contracts with the unions, which restricts the size (based on max pax)of the aircraft that the regional airlines may operate on their behalf
