Nonscheduled 14 CFR Part 135: Air Taxi & Commuter
Accident occurred Sunday, May 28, 2017 in Petersville, AK
Probable Cause Approval Date: 08/03/2017
Aircraft: DEHAVILLAND DHC 2, registration: N561TA
Injuries: 7 Uninjured.
NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
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 chose 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 to taxi back to the top. 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.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot’s selection of unsuitable terrain for taxiing, which resulted in a nose-over.
Additional Participating Entity:
Federal Aviation Administration / Flight Standards District Office; Anchorage, Alaska
