Narrative:

My 50 hour student and I were practicing night takeoff and lndgs. We had a flap failure. I thought I would let the student practice a slip to land. On final, the student let the airspeed climb and I fixated on airspeed not noticing that we were also low. The main right touched the top of a tree near the end of the runway. I took control of the airplane and landed uneventfully. As soon as we experienced the flap failure, I should have taken over control of the airplane per the regulations. I also should not have been distraction by the student's control of the airspeed and kept situational awareness, especially at night.
