Summary
On May 28, 2017, a Dehavilland DHC 2 (N561TA) was involved in an incident near Petersville, AK. All 7 people aboard were uninjured. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this incident to be: The pilot’s selection of unsuitable terrain for taxiing, which resulted in a nose-over.
The pilot of the ski-equipped airplane reported that, as the tailwheel touched down on the glacier, the snow was deeper and softer than he had expected. He added, that during the uphill landing, he elected not to stop the airplane and risk getting stuck. Instead, he completed a turn at the top of the landing area, but was unable to straighten the direction of travel enough for a takeoff. Subsequently, to straighten the airplane before the takeoff, he completed a left 360° turn.
During the downhill takeoff, the airplane had poor acceleration and insufficient airspeed to fly, so he aborted the takeoff. As he reduced the engine power, the airplane slowed to what he felt to be a reasonable speed and he initiated a left turn.
This incident is documented in NTSB report GAA17CA294. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N561TA.

Aircraft Information
Analysis
The pilot of the ski-equipped airplane reported that, as the tailwheel touched down on the glacier, the snow was deeper and softer than he had expected. He added, that during the uphill landing, he elected not to stop the airplane and risk getting stuck. Instead, he completed a turn at the top of the landing area, but was unable to straighten the direction of travel enough for a takeoff. Subsequently, to straighten the airplane before the takeoff, he completed a left 360° turn.
During the downhill takeoff, the airplane had poor acceleration and insufficient airspeed to fly, so he aborted the takeoff. As he reduced the engine power, the airplane slowed to what he felt to be a reasonable speed and he initiated a left turn. Subsequently, the right ski dug into the snow, and the airplane came to rest inverted.
The airplane sustained substantial damage to the empennage.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
