What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The student was on his last flight to receive his tail wheel endorsement and was reported as being proficient and prepared to land on a remote backcountry dirt airstrip located at lat/long 41.1757, -112.3808. The strip is 10 feet wide and 1828 feet long, with about 200 feet of grass to either side. Upon landing, the aircraft was centered on the runway and the tail wheel planted. When the student applied the brakes, he locked the left brake, and froze. The instructor could not get the student to release the brake in time to avoid the ground loop. At approximately 20 knots, the aircraft ground looped causing substantial damaging the right wing tip and right elevator. No injuries were sustained.
