Narrative:

Wind was calm. Student and myself were doing touch and goes on runway 27 flying right traffic pattern. Commuter airline trainer was doing practice NDB approachs to runway 9. Controller told commuter to 'break off your approach on the approach end of runway 9, turn left to 030 degrees and climb to 3000 ft.' on climb out approximately 200-300 AGL our aircraft encountered the wake turbulence from the commuter. Our plane went into an approximately 45 degree bank and the nose pitched up. Flight instructor took controls, leveling wings and pitching nose down to prevent takeoff and departure stall. There was no warning about wake turbulence from the controller. I feel this was a dangerous situation and could have been avoided by telling the other aircraft to break off the approach sooner and also by issuing a wake turbulence advisory.
