NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

The private certificated pilot departed with a passenger in a float-equipped airplane for the purpose of dropping food packages to a group of hikers at a remote cabin. After arrival in the area, the pilot performed two low-level passes. On the third pass, the passenger, in the rear seat of the airplane, began dropping packages. The airplane then made a turn, and flew between the cabin and the side of a mountain slope, located north of the cabin, on what appeared to the be the fourth pass. As the airplane came by the cabin, witnesses saw the left wing and nose come up. The airplane then turned 180 degrees to the right, and descended to the ground in a nose-down attitude. The airplane collided with the ground in a near-vertical attitude. Members of the group cared for the pilot and passenger, and one member departed the cabin on-foot to notify law enforcement personnel. Rescue personnel responded and transported the passenger to a hospital. Examination of the airplane did not disclose any preimpact mechanical malfunction.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to maintain adequate airspeed while performing a low level pass, which resulted in an uncontrolled descent and collision with terrain. A factor contributing to the accident was an inadvertent stall.
