Human Factors
Upon receiving taxi instructions to return to the ramp for parking; Student Pilot under my supervision did the taxi. At taxiway Charlie; by the wash racks we turned to left. Student got off the center line and I advise him to keep centerline and prepare to turn left again by reducing airspeed. At same time I finished giving student pilot those instructions; he added full power instead of reducing it. That action was faster than my reaction time to counteract. Immediately and simultaneously; I hit the brakes steering away from the hangar on the right that we were pointed at and pulled the throttle out. The right wingtip light hit the corner of hangar door. Wingtip lights were completely broken and there was a hole the size of a lime in the wingtip. The hangar door had a scratch on the corner where the wingtip hit. No other damages were found. Airplane was placed into maintenance. Student Pilot was instructed during the post flight on actions to avoid this situation of ever happening again. Chief pilot instructed CFI to enhance attention at all times; even when student is doing well.
C172 flight instructor reported taxiing problems by the student which resulted in striking a hanger with a wingtip.
