Circumstances:
While on a crop-spraying flight for the sovkhoz (state farm) 'Rossiya' located in the Altai district of Khakassia, the crew got distracted from piloting for unknown reason. While flying a turn at a height of some 15-20 metres, the aircraft dove into the ground and crashed in a field located about 45 km south of Abakan. A pilot and the passenger, a local guide, were killed, while the second pilot was seriously injured.
Probable cause:
Crew distraction.

Circumstances:
The aircraft was engaged in a local spraying mission, carrying a crew of three and a load of 3,666 gallons of insecticides. After takeoff from runway 23, while in initial climb, the airplane entered a flat attitude then descended until it struck trees and crashed in flames about 3 km southwest of the airport. The aircraft was totally destroyed by a post crash fire and all three crew members were killed.
Probable cause:
Investigations determined that the flaps were retracted at the time of the accident while the aircraft was flying at a relative low speed during initial climb. It is believed that this was likely a result of a premature retraction of the flaps on part of the flying crew below the minimum altitude of 500 feet, resulting in a loss of altitude.

Circumstances:
The crew was engaged in a crop spraying flight (herbicides on corn field) for the sovkhoz (state farm) 'Gornyak' located in the Starobeshevo district of the Donetsk region.

The aircraft was destroyed by a post crash fire, a pilot was killed as the second occupant was seriously injured.
Probable cause:
Error of judgment on part of the pilot-in-command who completed a sharp turn to the right while the aircraft's speed was too low, causing the airplane to stall and to crash.

Circumstances:
The crew was engaged in a crop spraying mission in the region of Union Springs and departed Montgomery-Franklin Airport in the early morning. While flying at low height above a wooded area, the airplane struck tree tops and crashed in flames. The aircraft was destroyed and both crew members were killed.
Probable cause:
Collision with trees after the pilot-in-command misjudged speed and altitude. The following factors were reported:
- Diverted attention from operation of aircraft,
- Jettisoned load,
- Aircraft descended and hit ground in near level flight attitude.

Circumstances:
Following a power loss the pilot attempted a forced landing on a relatively level hilltop, but during the roll the nosewheel entered a deep depression and was forced rearward and upward into the cockpit floor. Fire broke out in the engine bay immediately thereafter and flashed back into the cockpit as the pilot opened the canopy to escape. The pilot evacuated safely while the aircraft was written off.
Probable cause:
Engine failure and fire for undetermined reason.

Circumstances:
While completing a crop spraying flight, the pilot lost control of the airplane after the right wing detached in flight. The aircraft crashed in an open field and was destroyed. The pilot, sole on board, was killed.
Probable cause:
The accident was caused by in-flight separation of the starboard wing due to a loss of structural strength brought about by extensive fatigue cracks in the lower centre wing wraparound and internal doublers inboard of Sta. 142, initiation and propagation to failure of the RH wing cracks being due to consistent overstress.

Circumstances:
The pilot was engaged in a superphosphate spreading operation over hilly farmland. Just before noon he took off on his 72nd sortie of the day with the usual load of 14 hundredweight in the hopper. On the completion of the first sowing run the aircraft was turned to position it for the next run. As usual this put the plane out of sight to those on the airstrip as it passed behind an intervening spur. At about the time the plane was expected to reappear a loud bang was heard by the crew on the strip, and moments later a column of smoke was seen rising from behind the spur. The aircraft was found wrecked and burning. This was not a survivable crash. Physical evidence at the site showed that the Fletcher had struck the ground with its right wingtip first while banked past the vertical with the fuselage then impacting in a perpendicular attitude. Propeller score marks on the pasture indicated that the engine was developing power at the moment of the crash. The weather was fine and clear with a southwesterly breeze of about 5 knots. Not a cause factor in the accident. The pilot had recently completed an agricultural pilot course and had almost accumulated the fifty hours of supervised productive flying required before being cleared for unsupervised operations.
Probable cause:
No evidence of mechanical or structural failure was found. Weather conditions were considered as good. The crash investigation found that the most probable cause of the tragedy was a catastrophic physical incapacity of the pilot causing him to lose control of the aircraft.

Circumstances:
Late in the afternoon of 30/8/72 two aircraft were conducting an aerial topdressing operation at Clayton Station. One of the pilots observed the other aircraft operating normally. When he looked again moments later he saw smoke and flames on the side of a ridge in the working area. Realizing that there had been an accident he immediately flew back to the airstrip and raised the alarm. ZK-CFQ had struck the ground with its port wingtip while making a 180 degree RH turn within the confines of a valley. Physical evidence showed that the plane was banked at an angle of 68 degrees when the wingtip touched the slope. The aircraft was destroyed by impact forces and fuel from a ruptured tank ignited completing the destruction. Evidence also showed that the engine was producing high power at the moment of impact. The all-up weight and C of G were found to be well within the permitted limits. The other pilot reported seeing an interruption in the flow of fertilizer in the final sowing run, but there was no sign of a blockage in the hopper outlet. The hopper was empty. The weather was perfect for aerial topdressing, CAVU and still air. An autopsy revealed that the 34-year-old pilot had received no fatal injuries in the impact, but there was evidence of coronary occlusion due to arteriosclerosis heart disease. It was concluded that the pilot had died from a heart attack and traumatic hypoxia. It was not clear if the heart attack occurred before or at the time of impact. It would appear however, from the steep angle of bank so close to the ground, that pilot had become incapacitated and had lost control of his aircraft.

Loss of control at low height for undetermined reason.
