Narrative:

Departed the airport on a private pilot instruction flight; returning to our flight school. We had started a left turnout and established a course to the west. At 1;500 ft after takeoff; I heard a loud bang from the engine; smoke and the smell of burnt oil in the cockpit. At full forward throttle we had 1;900-2;000 RPM. Then shortly after it dropped to just above idle at full forward throttle. As the instructor; I took the controls; turned the aircraft back to the field; performed the emergency landing checklist and landed safely on the runway. In coordination with maintenance; the problem was established as a cracked cylinder.
