Narrative:
A Planemaster Ltd Cessna 208B Super Cargomaster, performing cargo flight PMS1670, from Wichita Dwight D. Eisenhower National Airport (ICT/KICT) to Hays Municipal Airport (HYS/KHYS) crashed in wheat field terrain northwest of La Crosse, Rush County, Kansas.
The aircraft took off from ICT at 07:52 local time (12:52 UTC). At 08:25, the HYS automated weather observation service was reporting, in part, winds from 080° at 11 knots, visibility 1 statute mile, and overcast clouds at 200 ft above ground level.
The pilot made an ILS approach to runway 34 but was forced to execute a missed approach. The pilot stated to ATC his intention to attempt the ILS approach to runway 34 a second time.
At 08:41, the HYS weather indicated that visibility had dropped to 0,25 statute mile in fog. Again, the pilot performed a missed approach.
About 08:59 the pilot stated his intention to divert to Great Bend Airport (GBD), Kansas. The airplane began a turn to the south toward GBD while climbing to about 7,000 ft.
Around 09:06, the pilot began making unintelligible radio communications that air traffic controllers stated were unreadable. About 09:15, the controller asked the accident pilot if he was turning directly to GBD. After an unintelligible response from the pilot, the controller stated alright plane master sixteen seventy it's very difficult to understand there might be something wrong with uh your cockpit or your pressurization plane master sixteen seventy oxygen oxygen. About a minute later, the pilot was more easily understood.
However, about 09:18, ATC made a transmission with no response from the pilot. At the same time the airplane began a descent and left turn.
About 09:20, an unintelligible response was received from the accident airplane. ATC then made numerous transmissions to the accident pilot urging him to utilize oxygen and open a window. No further communications were received from the accident airplane.
The aircraft was found to have crashed in a field. The airplane's tail and wings were visible above ground, with the forward fuselage and engine section buried several feet under the terrain, consistent with a near-vertical, high-speed impact. The main landing gear was bent aft towards the tail with the left and right main wheel protruding from the ground.
Probable Cause: "An infight loss of control as a result of pilot impairment, the cause of which could not be determined."
