Circumstances:
The aircraft was operating from an agricultural airstrip 600 feet above mean sea level, spreading superphosphate over moderately steep undulating terrain. The duration of each flight was 6-7 minutes. The accident flight was the seventh and probably intended to be the last for the day. A witness, who was situated under the flight path, reported that the aircraft was tracking east-north-east in what appeared to be normal flight. Her attention was distracted for a few moments and when she next saw the aircraft it was in a near vertical dive with the upper surface of the wings facing her. The aircraft then struck the hillside and burst into flames. Examination of the wreckage did not reveal any pre-existing defect which may have contributed to the accident. Impact marks on the propeller indicated that the engine was operating at impact. The superphosphate load remained in the hopper and the emergency dump system actuating lever was in the closed position. Inspection indicated that the dump system was serviceable prior to impact. Calculations indicated that at the time of the accident the aircraft, although heavily loaded, was operating within the flight manual maximum weight limitation. A light north-easterly wind was observed at the airstrip. However, at the accident site, which was about 250 feet higher, the wind was a moderate west-north-westerly. Sky conditions were clear with a visibility of 30 km. The aircraft probably experienced windshear and turbulence as it encountered a quartering tailwind approaching the ridgeline. The result would have been a reduction in climb performance and it is likely that the pilot attempted to turn the aircraft away from the rising terrain. During the turn it appears that the aircraft stalled and that the pilot was unable to regain control before it struck the ground.
Probable cause:
The reason the pilot did not dump the load when the climb performance was reduced could not be determined.
The following factors were determined to have contributed to the accident:
1. Shifting wind conditions conducive to windshear and turbulence were present in the area.
2. The aircraft was climbing at near to maximum allowable weight.
3. Control of the aircraft was lost with insufficient height available to effect a recovery.

Captain / Total flying hours:

Captain / Total hours on type:
330.00
Circumstances:
The pilot, sole on board, was engaged in a spraying mission in Kaikohe. The first sowing operation was completed shortly after 0700LT. While flying at low height in good weather conditions, the aircraft banked left to an angle of 45° then nosed down to 30° and crashed 500 metres from the Kaikohe Aerodrome. The aircraft was destroyed and the pilot was killed.
Probable cause:
The position of the turn towards the higher ground may have deprived the pilot of a visual horizon causing him to fly too slowly and the plane to stall and spin. No technical anomalies were found on the aircraft.

Circumstances:
The day's operation commenced at about 06:30 with the student flying and the instructor operating the loader.The intention was to fly for two hours when a break would be taken in order to rest the trainee pilot, check the fuel state, and review the sowing operation so far. Shortly before 08:20 the trainee took off on what was about the twentieth sowing flight of the day. The Fletcher was loaded with 19 hundredweight (cwt) or 965 kg of lime in the hopper. The usual pattern was flown and the aircraft was positioned for a sowing run along a ridge face at about 100 feet AGL. However, on this run no lime was dropped and at about the usual commencement point for sowing the aircraft made a sharp turn to the left and flew out over level ground, away from the ridge. After turning through about 120 degrees the plane pitched nose-down suddenly and dived almost vertically into the ground. It bounced over a hedge and came to rest 10 metres beyond the initial point of impact. This was not a survivable crash. Despite the spillage of considerable fuel no fire broke out. The flying weather was calm with good visibility. Weather was not a factor in this accident.
Probable cause:
No firm reason for the pilot to abandon his sowing run and make a steep turn away from the ridge could be found. It was noted that the change of heading took the plane on a course towards the sun and also a 100- feet-tall tree that may have caused the pilot to take abrupt avoiding action, causing the plane to stall and fall into an incipient spin from which control could not be regained owing to the limited height available.

Circumstances:
The pilot, sole on board, was completing a crop-spraying flight in Leninsky, district of Timashevsk. En route, the engine lost power then failed. The pilot reduced his altitude in an attempt to make an emergency landing when the right wing struck trees, causing the aircraft to crash. The pilot was injured and the aircraft was destroyed.
Probable cause:
Engine failure after particles of rubber sealing rings went into the cylinder head, causing the failure of cylinder n°4 and 6.

Probable cause:
Engine failure after carburetor iced up.
