Narrative:

Taxiing from the runup area to runway 17L we pulled up behind another aircraft. The other aircraft was delayed by approach control for departure. Our aircraft was advised to taxi into position and hold. While trying to make a hard right turn, my student did not stop when I advised him. Our left wingtip hit the tail of the other aircraft. It scraped the paint on our wingtip. No damage visible to the other aircraft. A contributing factor was that the co-pilot side did not have brakes. Supplemental information from acn 229179: I started to taxi south (left) of small aircraft 2 but, due to ice and snowpack, my instructor said to go between small aircraft 2 and the other waiting small aircraft 3 to the north. Both planes departed to the hold line and both departed. To prevent recurrence, the next time I will refuse to taxi when in congested traffic.
