On approach to runway 18 at Okiwi, New Zealand, the aircraft encountered windshear on short final as the pilot reduced power to land. The pilot was unable to arrest the descent rate and the aircraft landed heavily. Damage was caused to both landing gear oleos and one brake unit, with rippling found on the upper and lower skin of each wing. One passenger sustained a back injury, which was later identified as a fractured vertebra. The pilot was aware of fluctuating wind conditions at Okiwi and had increased the approach speed to 70 knots as per company standard operating procedures. The pilot reported that despite this, the airspeed reduced rapidly and significantly at 10 to 15 feet agl, leaving little time to react to the situation.

At about 1300 on Sunday 5 July 2009, ZK-LOU, a 3-engined Britten Norman BN2A Mk III Trislander operated by Great Barrier Airlines (the company), took off from Great Barrier Aerodrome at Claris on Great Barrier Island on a regular service to Auckland International Airport. On board were 10 passengers and a pilot, all of whom were wearing their seat belts. That morning the pilot had flown a different Trislander from Auckland International Airport to Claris and swapped it for ZK-LOU for the return flight because it was needed for pilot training back in Auckland. Another company pilot had that morning flown ZK-LOU to Claris from North Shore Aerodrome. He had completed a full engine run-up for the first departure of the day, as was usual, and said he noticed nothing unusual with the aeroplane during the approximate 30-minute flight. For the return flight the pilot said he completed the normal after-start checks in ZK-LOU and noticed nothing abnormal. He did not do another full engine run-up because it was not required. He taxied the aeroplane to the start of sealed runway 28, applied full power while holding the aeroplane on brakes and rechecked that the engine gauges were indicating normally before starting the take-off roll. The aeroplane took off without incident, but the pilot said when it was climbing through about 500 feet he heard an unusual “pattering” sound. He also heard the propellers going out of synchronisation, so he attempted to resynchronise them with the propeller controls. He checked the engine’s gauges and noticed that the right engine manifold pressure and engine rotation speed had dropped, so he adjusted the engine and propeller controls to increase engine power. At that time there was a loud bang and he heard a passenger scream. Looking back to his right the pilot saw that the entire propeller assembly for the right engine was missing and that there was a lot of oil spray around the engine cowling. The pilot turned the aeroplane left and completed the engine failure and shutdown checks. He transmitted a distress call on the local area frequency and asked the other company pilot, who was airborne behind him, to alert the local company office that he was returning to Claris. The company office manager and other company pilot noticed nothing unusual with ZK-LOU as it taxied and took off. The other pilot was not concerned until he saw what looked like white smoke and debris emanate from the aeroplane as though it had struck a flock of birds. Despite the failure, ZK-LOU continued to climb, so the pilot said he levelled at about 800 feet and reduced power on the 2 serviceable engines, completed a left turn and crossed over the aerodrome and positioned right downwind for runway 28. There was quite a strong headwind for the landing, so the pilot elected to do a flapless landing and keep the power and speed up a little because of the possibility of some wind shear. The pilot and other personnel said that the cloud was scattered at about 2500 feet, that there were a few showers in the area and that the wind was about 15 to 20 knots along runway 28. The visibility was reported as good. After landing, the pilot stopped the aeroplane on the runway and checked on the passengers before taxiing to the apron. At the apron he shut down the other engines and helped the passengers to the terminal, where they were offered drinks. The company chief executive, who lived locally, and a local doctor attended to the passengers. Three of the passengers received some minor abrasions and scrapes from shattered Perspex and broken interior lining when the propeller struck the side of the fuselage.

On Friday 20 July 2001, at around 0450, Partenavia P68B ZK-DMA was abeam North Shore Aerodrome at 5000 feet in darkness and enroute to Whangarei, when it suffered a double engine power loss. The pilot made an emergency landing on runway 21 at North Shore Aerodrome, but the aircraft overran the end of the runway, went through a fence, crossed a road and stopped in another fence. The pilot was the only person on board the aircraft and received face and ankle injuries. The aircraft encountered meteorological conditions conducive to engine intake icing, and ice, hail or sleet probably blocked the engine air intakes. The pilot had probably developed a mindset that dismissed icing as a cause, and consequently omitted to use alternate engine intake air, which should have restored engine power.

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.

An aerial topdressing operation was being undertaken from a sloping airstrip located on a headland near Matakana. The fertilizer to be applied was granulated superphosphate totaling 60 tonnes. The aircraft arrived at the airstrip and while waiting for the loader to arrive the pilot walked the length of the runway, then requested that the farmer cut down some saplings at the end of the strip that might obstruct his climb out path. Upon arrival of the loader the pilot instructed the driver to place 18 hundredweight (cwt) or 915 kgs of fertilizer in the aircraft. This was done, along with the addition of some fuel, and the first flight of the operation commenced. The driver did not observe the take off but while reloading his vehicle at the bin noticed a cloud of fertilizer dust off the end of the strip, indicating that the pilot had jettisoned the load. A few minutes later the driver sighted the aircraft briefly through a gap in the trees. It was flying, apparently normally, at about sowing height and on a reciprocal course to the take off direction. A faint trail of fertilizer was coming from the hopper. The plane then disappeared behind some trees and the driver did not see it again. Just after losing sight of the aircraft he saw what seemed to be a piece of red paper fluttering to the ground. When the aircraft failed to land a search was made and the wreckage of ZK-CBI was found in dense scrub about 350 metres to the left of the departure end of the airstrip. The pilot, sole on board, was killed. The investigator found that the pilot had initiated jettisoning the load 36 metres before the boundary fence. It was not clear whether the plane was still on the ground or was airborne at a low speed when a collision with the concrete post and wire fence occurred. Two posts had almost completely severed both halves of the " all flying " tailplane or stabilator. The outboard left hand section was retained by the trim tab only. The outboard part of the right hand side of the stabilator later detached and was found 150 metres from the crash site. With this degree of damage to the tailplane horizontal control must have been difficult, but the pilot was able to clear a low ridge ahead and fly out over a large basin where a 180 degree turn was completed in order to land back on the airstrip. Before the approach could be completed however, the outer part of the RH side of the stabilator separated and the aircraft dived steeply to the ground. The aircraft was destroyed by the severe impact. Fire did not break out. This was not a survivable crash.

Crashed in unknown circumstances in Kaipara Harbour while on a flight from Mechanics Bay. Both pilots were killed.

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.

On final approach to Auckland-Ardmore Airport, the aircraft's speed increased from 165 to 211 knots. The pilot-in-command (first officer) completed a last turn to join the runway 05 but was unable to locate it due to heavy showers. Too low, the airplane struck water surface and crashed in shallow water 1,025 meters short of runway 05 threshold. A pilot and a passenger were killed while two other occupants were injured.

For unknown reasons, the four engine airplane landed too far down the runway at Ardmore Airport. After touchdown, the pilot started the braking procedure when the left brakes failed. The airplane veered off runway to the right, struck a drainage ditch and came to rest with serious damages to its nose gear, engines and both wings. The pilot was uninjured and the aircraft was not repaired.

The pilot had flown from the farm earlier in the morning before going away for about two hours and then returning. At about 08:00 the property owner saw the plane approaching and making a low run over the airstrip apparently in order to frighten away some cattle obstructing the landing area.. The owner, a pilot himself, had experienced a similar situation before and went move the stock out of the way. He had lost sight of the aircraft for a brief period when he heard a bang and then the plane came back into view, rolling to starboard until inverted, and diving vertically into a hillside and exploding. Ground evidence showed that the Fletcher had struck with its right wing tip a 400 pound ( 180 kg ) cattle beast, killing the animal and dislodging the metal wing tip fairing which was found nearby with its leading edge crushed. Starting a few metres further on a 46 metres long scrape mark was visible on the surface having been made by the exposed end of the outer wing. The aircraft then collided with the corner of a hangar, the outboard end of the right wing contacting the building about 2.5 metres above ground level and 1 metre below the top. This impact caused the separation of the right outer wing panel. The plane, now out of control, cleared the top of another hangar and adjacent tall trees before diving into a hillside, exploding in flames and breaking up as it tumbled down the slope. The aircraft was destroyed and the pilot was killed.
