The NTSB reported Afghanistan's Civil Aviation Authority delegated the investigation of the accident to the NTSB.
On Jan 24th 2017 the NTSB released their final report concluding the probable cause of the accident was:
the early reduction of engine thrust that resulted in an excessive sink rate and nose high pitch attitude during the landing flare.
Contributing to the accident was a significant change in the vertical and horizontal wind components just prior to touchdown.
The NTSB described the damage: "The airplane was substantially damaged by deformation and wear due to runway contact resulting in structural damage to the fuselage skin, stringers, and frames. The skin on the lower fuselage was worn through to structure exhibiting signs of loss of material and multiple see-through holes and cracks over a 25 foot length from station 1395 rearward to station 1417. Internal damage to the frame included multiple damaged stiffeners and cracked web from frame station 1395 rearward to station 1562. Five bays were damaged at the lower end of the aft pressure bulkhead at station 1582, the web was deformed and the lower frame was bent."
The NTSB reported the wind conditions changed just prior to touchdown: "Wind components calculated from FDR data indicated that in the 4 seconds prior to touchdown, vertical wind transformed from a 6 feet per second (fps) updraft to a 19 fps downdraft and a 17 knot headwind just prior to touchdown changed to a 1 knot tailwind."
The NTSB reported: "The flight crew briefed a planned reference speed of 145 knots. FDR data indicated that during the last 1000 feet of the approach descent, the autothrottle was engaged and the airspeed varied between about 162 knots and 150 knots and engine N1 varied between about 81% and 62%. The autothrottle was disconnected at about 210 feet above the ground when the N1 was about 50%. Subsequently, the N1 was gradually reduced to about 40% N1 by about 110 feet above the ground and remained there until touchdown. Data from the FDR indicated the airplane touched down at approximately 140 knots. The pitch increased from approximately 1° just prior to the flare to the maximum pitch reached during landing of 9.5° and the maximum vertical acceleration recorded was approximately +2.5 G's."
