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 aircraft had been chartered to fly a German group to a number of tourist destinations in New Zealand. It had departed from Glentanner on a VFR flight to Queenstown. The flight was to include scenic flying in the Mount Cook region. A 'taxiing' call was received at 1153 hours but later attempts by Christchurch Flight Information to communicate with the aircraft were unsuccessful. Aircraft wreckage, which proved to be that of ZK-NOM, was sighted during the afternoon in a severely crevassed and pinnacled area of Franz Josef Glacier, at an elevation of 4,500 feet amsl. The crew and passengers had all sustained fatal injuries on impact.
Probable cause:
The probable cause of this accident was the decision to attempt to climb above the lower region of Franz Josef Glacier which had an average slope steeper than the aircraft could outclimb. A causal factor was the crew's lack of training and experience in mountain flying rendering them vulnerable to visual misperception. Probable contributing factors included a cloud layer limiting the position and altitude at which climb could be commenced and an optimistic assessment of the aircraft's capability and progress during the climb.

Circumstances:
The pilot, sole on board, was engaged in a local topdressing flight in Waimangu. Shortly after takeoff, the engine lost power. The aircraft lost height then the right wing struck a hedge and it crashed. The pilot was killed.
Probable cause:
An injector was completely blocked by a grain of sand which caused a significant power loss just after takeoff.

Circumstances:
On final approach to Wellington Airport, the crew selected gear down but the left main gear failed to lock down. The crew decided to divert to Blenheim Airport for an emergency landing. Upon touchdown on runway 25, the left main gear collapsed and the aircraft came to rest. Both pilots escaped uninjured.
Probable cause:
The failure of the left main undercarriage to fully extend was caused by the seizure of the piston rod within the undercarriage jack assembly. The piston rod and the spring housing through which it passed had become scored, eventually resulting in the seizure. The piston rod had been installed, new, in the jack assembly some seven months earlier and had completed 787 landings. Further investigation found that the synthetic wiper ring had been installed incorrectly and would allow foreign material to find its way into the spring housing when the undercarriage was retracted. Additionally, hydraulic components on the undercarriage may have become contaminated during cleaning in an inadequately filtered cleaning booth, which was also used for general cleaning involving the use of abrasive pads.

Circumstances:
Two Cessna 207 Skywagon of Air Fiordland (ZK-DQF) and Milford Sound Scenic Flights (ZK-DAX) were engaged in a charter flight from Milford Sound to Queenstown, carrying Japanese tourists. On board ZK-DQF were six passengers and one pilot and four passengers and one pilot on board ZK-DAX. En route, while cruising over the Milford Sound area, both aircraft collided. While the pilot of ZK-DAX was able to perform an emergency landing, ZK-DQF entered a dive and crashed, killing all seven occupants. All five people on board ZK-DAX were rescued but both aircraft were destroyed.
Probable cause:
The mid-air collision occurred because neither pilot saw the other aircraft in time. Causal factors were the pilot's restricted cockpit vision, a lack of pilot awareness to maintain an effective look-out; the unnecessarily high density of traffic and the unplanned merging of two streams of aircraft after a weather deterioration necessitated a change in route after departure.

Circumstances:
The twin engine aircraft was completing an on-demand scenic flight from Wanaka to Milford Sound, carrying nine tourists and one pilot. En route, in unknown circumstances, the aircraft crashed on the Blue Duck Glacier located near Milford Sound. The wreckage was found few hours later at the altitude of 5,400 feet. All 10 occupants were killed.
Probable cause:
The lack of direct evidence to account, operationally or structurally, for the manner in which the aircraft struck the mountain slope, the remoteness of the site which provided no witness observation to describe the aircraft’s flight path prior to the event and the absence of any survivor, combined to preclude a determination of the accident’s probable cause.

Circumstances:
Flight Air Freight 1 was a scheduled night freight flight between Palmerston North, Auckland and Christchurch. The crew consisted of a training captain and two new co-pilots who were to fly alternate legs as co-pilot and observer. The co-pilot’s ADI of the Convair CV-580 in question had a known intermittent defect, but had been retained in service. The aircraft’s MEL however did not permit this flight to be undertaken with an unserviceable ADI. The aircraft nevertheless departed Palmerston North and arrived at Auckland at about 20:30. It was unloaded and reloaded with 11 pallets of cargo. On the next leg, to Christchurch, the handling pilot was to be the other co-pilot. Although she had completed her type rating on the Convair 580 this was her first line flight as a crew member. The flight was cleared to taxi to runway 23 for departure. Takeoff was commenced at 21:59. The aircraft climbed to a height of approx. 400 feet when it pitched down. It entered a gradual descent until it contacted the ground 387 m beyond the end of runway 23 and 91 m left of the extended centreline. The aircraft then crashed and broke up in the tidal waters of Manukau Harbour. The aircraft disintegrated on impact and all three crew members were killed.
Probable cause:
The probable cause of this accident was the training captain’s failure to monitor the aircraft’s climb flightpath during the critical stage of the climb after take-off.

Circumstances:
The student agricultural pilot was operating under the supervision of an instructor. The aircraft had just taken off and was turning in the valley to gain height in order to clear high terrain which lay between the airstrip and the sowing area. Witnesses heard the engine misfire and saw the aircraft lose height while turning to avoid some high ground, collide with the hillside, and catch fire. The pilot, sole on board, was killed. The aircraft was destroyed.
Probable cause:
The aircraft suffered a temporary loss of engine power at a critical time after takeoff. The cause of the power loss was not determined, but may have been fuel contamination.
