The mission started at 1505LT and two first missions were completed successfully. During the third circuit, while flying at low height, the pilot attempted to avoid power cables and initiated a evasive manoeuvre when the airplane, at a speed of 163 km/h, struck an electric pylon and crashed in flames. Both occupants were killed.
Probable cause:
The accident was the result of an inadvertent loss of altitude due to the pilot being distracted and not paying sufficient attention to the flight.

Probable cause:
Collision with dirt bank during swath run after the pilot misjudged altitude and clearance. The following contributing factors were reported:
- Windshield dirty, restriction vision,
- Sunglare,
- Goggles not used,
- Spray from another aircraft collected on windshield according to the pilot.

Circumstances:
While completing a crop spraying mission, the crew encountered technical problems and decided to divert to Rivière-du-Loup Airport for an emergency landing. After touchdown, the airplane was unable to stop within the remaining distance, overran, lost its undercarriage and came to rest few dozen meters further. All four crew members escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Failure of the hydraulic system in flight, causing the brakes to be inoperative.

Circumstances:
The crew started at 0440LT in the morning a crop spraying mission on behalf of the kolkhoz of Abinsk. Fifteen rotations were successively completed until the lunchbreak. At 1820LT, the crew took off for a new series of four rotations. While no problems occurred during the first three rotations, the crew started the fourth rotation at an insufficient altitude. The pilot initiated a sharp turn to the right when the airplane banked right to an angle of 45° then nosed down and crashed in a field at a speed of 180 km/h. The copilot was seriously injured while the captain was killed. The copilot died from his injuries four hours later.
Probable cause:
The crew initiated the last rotation in a wrong configuration and it was determined that the distance between the aircraft and the ground during the last turn to the right did not allow the crew to correct the situation and avoid the impact with the ground.

Circumstances:
The pilot commenced work that day at 07:30, flying to an airstrip from where topdressing operations were to be carried out. At about 08:30 he took off on a survey flight accompanied by the lessee of the property. The passenger pointed out to the pilot the location of a 220 kilovolt power transmission line consisting of six conductor wires that ran above the eastern section of the farm, the area to be topdressed. The pilot then used the airstrip to finish a sowing operation on another farm. On the completion of that task the pilot turned his attention to topdressing the area he had surveyed some three hours earlier. With the aircraft refueled he took off to make his first runs. ZK-CPN did not return from this flight. Two men working on a fence line saw the aircraft approaching from the direction of the airstrip. It passed out of their sight behind a large knoll, but they could tell from the sound of the motor that it was making sowing runs. The Fletcher then came back into view banking steeply and turning right. The men saw " something white " fall from the plane just before it dived into the ground. Rushing to the crash scene they found the wreckage of ZK-CPN lying upside down in a creek. Fire had not broken out.There was no sign of life. The pair set off at once to get assistance.The investigation showed that 1.4 meters of the outboard section of the right wing had been severed from the airframe by one of the lower conductor wires of the high voltage transmission line that ran above the sowing area. Evidence of impact by an aircraft was found on the wire. The RH aileron balance was found some distance away from the severed wing section and had been separated by impact with the wire as well. The aircraft had rolled uncontrollably to the right and dived, crashing inverted and in a near-vertical attitude. This was not a survivable accident. The flying weather at the time was fine with only high cloud. The visibility was estimated as 30 km.
Probable cause:
The investigator found that the probable cause of this accident was that damage sustained when the aircraft collided with a power conductor wire deprived the pilot of control of the aircraft.

After completing 15 rotations, the crew departed for a new spraying flight when, at a height of 20 meters, the single engine airplane struck power cables located 1,600 meters from the village. It crashed 636 metres further and caught fire. Both pilots were seriously injured and evacuated to a local hospital. The copilot died few hours later and the captain a day later.
Probable cause:
Due to lack of evidences, it was not possible to determine the exact cause of the accident.

Circumstances:
Flying operations commenced at 07:30 a.m. after a delay caused by unfavourable weather. Twenty-seven loads of fertilizer were sown before the pilot and loader driver stopped for a 30-minute break. During this break the plane was refueled to capacity. After the break the pilot instructed the loader driver to put the same load in the hopper as before and then started his take off from the sloping airstrip. A witness thought the aircraft was taking longer to get off the ground than it had earlier. The loader driver looked up to see the plane in a left hand turn at a height of 30 to 40 feet just off the end of the strip and "porpoising". The angle of bank was then seen to increase to beyond vertical, and the plane crashed in an inverted attitude on the far side of a nearby gully. It was destroyed by impact and an intense fire and the pilot, sole on board, was killed. This was not a survivable accident.
Probable cause:
The accident investigator found that a freshening of the breeze during the rest and refueling break caused a slightly increased tailwind component on the take off run. This, combined with a full hopper load and full fuel meant that the aircraft no longer had sufficient distance available to become fully airborne in. The Fletcher had flown through a fence at the end of airstrip in a nose high attitude and the impact of a concrete post had damaged the left stabilator and wrenched it out of alignment with the fuselage. This damage also affected the free movement of the control. The fertilizer load was not jettisoned. There was no evidence that the MAUW had been exceeded but the plane was clearly overloaded for the ambient conditions. The CG was within the permitted limits. The weather was favourable for aerial topdressing with high cloud, a light breeze, and good visibility. The engine was developing full power right up until the final impact. The investigator concluded his report with the opinion that the probable cause of the accident was that the pilot was unable to maintain control after damage to a flight control system occurred when the aircraft failed to become airborne and struck a fence at the end of the airstrip.
