Human Factors
My student was doing a touch and go and practice in the pattern. Upon landing they added full throttle and then the plane started veering to the left due to left turning tendencies. They didn't add enough right rudder and I let it go too far without me adding the correction necessary. When I did add right rudder the student did as well and we started heading off the runway to the right. I took over controls and proceeded to rotate before we went off the runway. While rotating the wingtip scraped the runway. The plane continued to fly and we didn't notice the damage until the next student preflighted the aircraft. I let the students mistake go too far without correcting it myself. The plane got signed off by the A&P to keep flying untill the 100 hr inspection which the aircraft had less than 5 hours until. Then the airplane would be repaired by the Mechanic.
