NTSB Identification: ANC13FA093
14 CFR Part 91: General Aviation
Accident occurred Thursday, September 05, 2013 in Glennallen, AK
Probable Cause Approval Date: 04/23/2014
Aircraft: CESSNA 170B, registration: N170BN
Injuries: 1 Fatal.

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 pilot departed a remote, off-airport site to search for a moose he had shot earlier in the day. A witness observed the airplane perform a series of low-altitude maneuvers before flying by his location about 80 to 100 feet above the ground. The airplane then began a left turn, and the nose of the airplane pitched down abruptly and began to spin. The airplane subsequently descended vertically, nose first, and it collided with the tundra and brush-covered terrain.
A postaccident examination of the airframe and engine revealed no mechanical malfunctions or anomalies that would have precluded normal operation.
Given the lack of mechanical deficiencies with the airplane and engine, the witness statements, and the nature of the damage to the airplane, it is likely that the pilot inadvertently stalled and spun the airplane at a low altitude and was unable to recover.

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

The pilot’s failure to maintain adequate airspeed while maneuvering at a low altitude, which resulted in an aerodynamic stall/spin and impact with the ground.
