Event Sequence
While en route to his destination, the certificated commercial pilot noticed a man standing beside a snow machine, waving his arms. The pilot descended to about 100 feet above ground level (AGL) and flew over the individual. The man continued to wave, leading the pilot to believe he needed assistance. The pilot then climbed to 1,500 feet, contacted the Flight Service Station (FSS), and advised them to send help. After confirmation from the FSS specialist that help was on the way, the pilot descended again, deciding to drop a note to the man informing him that help was en route.
Stall and Landing
The pilot reported that with the landing gear down and full flaps extended, he began approaching the man. At about 75 to 100 feet AGL, the aircraft began to stall. Recognizing the stall, he added full power, but the stall progressed too quickly, causing the aircraft to touch down on a tributary of the Yukon River. Upon touchdown, the main wheels and right wing contacted deep snow, and the nose landing gear collapsed.
Damage
The accident resulted in damage to the aircraft, specifically the collapse of the nose landing gear after contacting deep snow.
