Circumstances:
The Sherpa departed Hurlburt Field AFB, Florida, on flight PAT528 to Oceana NAS, Virginia, carrying 18 passengers and a crew of three. While in cruising altitude over Georgia, the crew encountered poor weather conditions with thunderstorm activity, heavy rain falls, severe turbulences, windshear conditions and wind gusting up to 72 knots. The aircraft became unstable, lost 100 feet in three seconds then adopted a nose up attitude. Within the next 12 seconds, the aircraft suffered a positive aerodynamic acceleration then entered an uncontrolled descent, partially disintegrated in the air and eventually crashed in an open field. All 21 occupants were killed.

Probable cause:
The Collateral Investigation Board found the preponderance of the evidence concluded that the aircraft accident was due to crew error. The board found other factors present but not contributing directly to this aircraft accident. These factors may have influenced the crew's decision making process and aircraft performance. This is normally the case in most aircraft human factor accidents. The board did find the preponderance of the evidence directed the board toward the crew's failure to properly load the aircraft. In particular, the crew's failure to properly manage the weight and balance of the aircraft resulted in an 'out-of-CG' condition that exceeded the aircraft design limits, rendering the aircraft unstable and leading to a violent departure from controlled flight. Once the aircraft departed controlled flight, the rapid onset of significant G-force shifts rendered the crew and passengers incapacitated and unconscious and led to a structural break-up of the aircraft in flight. This ultimately resulted in the aircraft impacting the ground, killing all on board.

Circumstances:
The C-141B departed Norton AFB for a flight to Hurlburt Field with an intermediate stop at Peterson Field near Colorado Springs. The crew had to return back to Norton due to a leaking comfort pallet. At the end of the second leg, the crew were confronted with thunderstorms covering the approach path for the ILS approach to runway 36 at Hurlburt Field, the primary instrument runway. The crew requested the TACAN approach to runway 18, which was an approach over swampy terrain. The aircraft entered a high rate of descent, causing the GPWS to sound. The copilot reset two GPWS warnings and the descent was continued below the Minimum Descent Altitude (MDA) of 345 feet agl. The airplane finally impacted terrain in a wings level, nose low attitude. All eight occupants were killed.
Probable cause:
Controlled flight into terrain.

Circumstances:
The airplane departed Hultburt Field AFB at 0800LT on a training mission under call sign Moose 09. The assigned mission was a routine SEA serial spray training flight. The formation proceeded to a point 25 nm northwest of Panama City, Florida (the designated spray training area), arriving there at 08:35 CST. At this time a series of simulated defoliation runs were conducted over an open field. At approximately 08:50 CST Aircraft 54-0602 assumed the number three position in a right echelon formation for practice defoliation runs along a series of roads. At the completion of the first run the lead aircraft gave a command to place the aircraft in a "piggy back" formation, then climbed from 150 feet AGL to approximately 300 feet AGL and executed a 270 degree turn to the right. While in this turn the Number Three aircraft contacted the ground in a left wing low position, cartwheeled, immediately caught fire and was destroyed. The instructor pilot, two student pilots, and the flight engineer sustained fatal injuries.
