The crew was completing a training mission. In unknown circumstances, the single engine aircraft crashed in a prairie located near Mount Nicholas, between Queenstown and Te Anau, coming to rest upside down. Both pilots were seriously injured and the aircraft was destroyed.

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.

The aircraft crashed in unknown circumstances in Waitaanga while completing a spraying mission between Taumatunui and Mount Messenger. The aircraft was destroyed and the pilot, sole on board, was seriously injured.

The pilot, who was undertaking training toward a Grade 2 Agricultural Pilot Rating, began work at approximately 0625 hours on the day of the accident. The pilot and his instructor, who was in another topdressing aircraft, flew to a block of land to the south east of Rotorua where the pilot completed 15 sowing runs, while his instructor worked in the local vicinity in the second aircraft. The pilot and instructor completed the work on this block, had a break and then transited to the Waikite Valley, arriving at approximately 0945 hours. At 1045 hours, after refuelling his aircraft, the pilot commenced sowing a ‘special mix’ fertiliser, in an alternating pattern between the instructor and pilot, with two aircraft operating from the airstrip. The alternating pattern allowed the instructor to observe and supervise the pilot during the take off and landing phases, while allowing the operation to proceed efficiently. The pilot and instructor stopped for lunch after an hour of flying, refuelled once more and then continued with their work. The amount of fertiliser that was loaded into the pilot’s aircraft was progressively increased as the work proceeded. The initial load of product was 900 kg, gradually increasing by 50 kg increments, when the instructor was satisfied that the pilot’s performance allowed this increase. The last five loads carried prior to the accident were each 1100 kg. Nothing untoward was noticed during the sowing runs, apart from the pilot aborting one landing attempt, due to the wake turbulence from the instructor’s aircraft during take off. At the time of the accident the pilot was performing ‘clearing runs’, sowing on remaining areas of land not already covered by previous sowing runs. Immediately prior to the accident, the pilot called the instructor on the radio to enquire of his location. The instructor responded with “directly behind you on the other side of the woolshed”. A few seconds later, as the instructor approached to land at the airstrip, he observed the pilot’s aircraft flying in a westerly direction at approximately 400 ft AGL. He then saw the pilot’s aircraft make a slight turn to the left. Describing what he had seen as: “he started to climb and turn slightly to the left, then the plane was in a left hand spin”. The instructor thought at the time that the aircraft spun for one and a half rotations to the left, prior to being obscured by the ridge adjacent to the airstrip. The accident occurred in daylight, at approximately 1315 hours, at Waikite Valley, Rotorua, at an elevation of 1460 ft. Latitude S 38° 18.5', longitude E 176° 17.42'.

At about 1107 Eastern Standard Time on 01OCT2012, a de Havilland Aircraft Pty Ltd DH-84 Dragon, registered VH-UXG (UXG), took off from Monto on a private flight to Caboolture, Queensland under the visual flight rules (VFR). On board the aircraft were the pilot/owner and five passengers. The weather conditions on departure were reported to include a light south-easterly wind with a high overcast and good visibility. Sometime after about 1230, the aircraft was seen near Tansey, about 150 km north-west of Caboolture on the direct track from Monto to Caboolture. The aircraft was reported flying in a south-easterly direction at the time, at an estimated height of 3,000 ft and in fine but overcast conditions. At 1315, the pilot contacted Brisbane Radar air traffic control (ATC) and advised that the aircraft’s position was about 37 NM (69 km) north of Caboolture and requested navigation assistance. At 1318, the pilot advised ATC that the aircraft was in ‘full cloud’. For most of the remainder of the flight, the pilot and ATC exchanged communications, at times relayed through a commercial flight and a rescue flight in the area due to the limited ATC radio coverage in the area at low altitude. At about 1320, a friend of one of the aircraft’s passengers received a telephone call from the passenger to say that she was in an aircraft and that they were ‘lost in a cloud’ and kept losing altitude. Witnesses in the Borumba Dam, Imbil and Kandanga areas 70 to 80 km north-north-west of Caboolture later reported that they heard and briefly saw the aircraft flying in and out of low cloud between about 1315 and 1415. At 1348, the pilot advised ATC that the aircraft had about an hour’s endurance remaining. The pilot’s last recorded transmission was at 1404. A search for the aircraft was coordinated by Australian Search and Rescue (AusSAR). The aircraft wreckage was located on 3 October 2012, about 87 km north-west of Caboolture on the northern side of a steep, densely wooded ridge about 500 m above mean sea level. The Australian Transport Safety Bureau (ATSB) later determined that the aircraft probably impacted terrain at about 1421 on 01OCT2012. Preliminary analysis indicated that the aircraft collided with trees and terrain at a moderate to high speed, with a left angle of bank. The aircraft’s direction of travel at impact was toward the south-south-west.

On the afternoon of 13 October 2011, an Airlines PNG Bombardier DHC-8-103, registered P2-MCJ (MCJ), was conducting a regular public transport flight from Nadzab, Morobe Province, to Madang, Madang Province under the Instrument Flight Rules (IFR). On board the aircraft were two flight crew, a flight attendant, and 29 passengers. Earlier in the afternoon, the same crew had flown MCJ from Port Moresby to Nadzab. The autopilot could not be used because the yaw damper was unserviceable so the aircraft had to be hand-flown by the pilots. At Nadzab, the aircraft was refuelled with sufficient fuel for the flight to Madang and a planned subsequent flight from Madang to Port Moresby. MCJ departed Nadzab at 1647 LMT with the Pilot-in-Command as the handling pilot. The aircraft climbed to 16,000 ft with an estimated arrival time at Madang of 1717. Once in the cruise, the flight crew diverted right of the flight planned track to avoid thunderstorms and cloud. The Pilot-in-Command reported that communications between Madang Tower and an aircraft in the vicinity of Madang indicated a storm was approaching the aerodrome. He recalled that he had intended to descend below the cloud in order to be able to see across the sea to Madang and had been concentrating on manoeuvring the aircraft to remain clear of thunderstorms and cloud, so he had been looking mainly outside the cockpit. Because of the storm in the vicinity of the airport, he said there had been „some urgency‟ to descend beneath the cloud base to position for a right base for runway 07 at Madang, the anticipated approach. On this route, the descent to Madang was steep (because of the need to remain above the Finisterre Ranges until close to Madang) and, although the aircraft was descending steeply, the propellers were at their cruise setting of 900 revolutions per minute (RPM). Neither pilot noticed the airspeed increasing towards the maximum operating speed (VMO); the Pilot-in-Command reported afterwards that he had been „distracted‟ by the weather. When the aircraft reached VMO as it passed through 10,500 ft, with a rate of descent between 3,500 and 4,200 ft per minute, and the propellers set at 900 RPM, the VMO overspeed warning sounded. The Pilot-in-command reported that he had been about to ask the First Officer to increase the propeller speed to 1,050 RPM to slow the aircraft when this occurred. He raised the nose of the aircraft in response to the warning and this reduced the rate of descent to about 2,000 ft per minute, however, the VMO overspeed warning continued. The First Officer recalled the Pilot-in-Command moved the power levers back „quite quickly‟. Shortly after the power levers had been moved back, both propellers oversped simultaneously, exceeding their maximum permitted speed of 1,200 RPM by over 60 % and seriously damaging the left hand engine and rendering both engines unusable. Villagers on the ground reported hearing a loud „bang‟ as the aircraft passed overhead. The noise in the cockpit was deafening, rendering communication between the pilots extremely difficult, and internal damage to the engines caused smoke to enter the cockpit and cabin through the bleed air and air conditioning systems. The emergency caught both pilots by surprise. There was confusion and shock on the flight deck, a situation compounded by the extremely loud noise from the overspeeding propellers. About four seconds after the double propeller overspeed began, the beta warning horn started to sound intermittently, although the pilots stated afterwards they did not hear it. The left propeller RPM reduced to 900 RPM (in the governing range) after about 10 seconds. It remained in the governing range for about 5 seconds before overspeeding again for about 15 seconds, then returned to the governing range. During this second overspeed of the left propeller, the left engine high speed compressor increased above 110 % NH, becoming severely damaged in the process. About 3 seconds after the left propeller began overspeeding for the second time, the right propeller went into uncommanded feather due to a propeller control unit (PCU) beta switch malfunction, while the right engine was still running at flight idle (75% NH). Nine seconds after the double propeller overspeed event began, the Pilot-in-command shouted to the First Officer „what have we done?‟ The First Officer replied there had been a double propeller overspeed. The Pilot-in-command then shouted a second and third time „what have we done?‟. The First Officer repeated that there was a double propeller overspeed and said that the right engine had shut down. The Pilot-in-Command shouted that he could not hear the First Officer, who – just as the left propeller began governing again and the overspeed noise subsided – repeated that the right engine had shut down and asked if the left engine was still working. The Pilot-in-command replied that it was not working. Both pilots then agreed that they had „nothing‟. At this point, about 40 seconds after the propeller overspeed event began, the left propeller was windmilling and the left engine was no longer producing any power because of the damage caused to it by the overspeed. The right engine was operating at flight idle, although the propeller could not be unfeathered and therefore could not produce any thrust. On the order of the Pilot-in-Command, the First Officer made a mayday call to Madang Tower and gave the aircraft's GPS position; he remained in a radio exchange with Madang Tower for 63 seconds. The flight crew did not conduct emergency checklists and procedures. Instead, their attention turned to where they were going to make a forced landing. The aircraft descended at a high rate of descent, with the windmilling left propeller creating extra drag. The asymmetry between the windmilling left propeller and the feathered right propeller made the aircraft difficult to control. The average rate of descent between the onset of the emergency and arrival at the crash site was 2,500 ft per minute and at one point exceeded 6,000 ft per minute, and the VMO overspeed warning sounded again. During his long radio exchange with Madang Tower, the First Officer had said that they would ditch the aircraft, although, after a brief discussion, the Pilot-in-command subsequently decided to make a forced landing in the mouth of the Guabe River. The First Officer asked the Pilot-in-command if he should shut both engines down and the Pilot-in-command replied that he should shut „everything‟ down. Approximately 800 feet above ground level and 72 seconds before impact, the left propeller was feathered and both engines were shut down. The Pilot-in-Command reported afterwards that he ultimately decided to land beside the river instead of in the river bed because the river bed contained large boulders. The area chosen beside the river bed also contained boulders beneath the vegetation, but they were not readily visible from the air. He recalled afterwards that he overshot the area he had originally been aiming for. The aircraft impacted terrain at 114 knots with the flaps and the landing gear retracted. The Flight Attendant, who was facing the rear of the aircraft, reported that the tail impacted first. During the impact sequence, the left wing and tail became detached. The wreckage came to rest 300 metres from the initial impact point and was consumed by a fuel-fed fire. The front of the aircraft fractured behind the cockpit and rotated through 180 degrees, so that it was inverted when it came to rest. Of the 32 occupants of the aircraft only the two pilots, the flight attendant, and one passenger survived by escaping from the wreckage before it was destroyed by fire.

The single engine aircraft was performing a taxi flight from Whitegrass Airport located on Tannu Island, to Port Vila, with six passengers and a pilot on board. While approaching Efate Island, the pilot encountered poor weather conditions with heavy rain falls and attempted an emergency landing in the garden of the Lagon Resort, south of Port Vila. On touchdown, the airplane lost its nose gear and left main gear, cartwheeled and came to rest, broken in two. All occupants were slightly injured and the aircraft was damaged beyond repair.

At 0445 Eastern Standard Time on 24 February 2011, the pilot of an Aero Commander 500S, registered VH-WZU, commenced a freight charter flight from Cairns to Horn Island, Queensland under the instrument flight rules. The aircraft arrived in the Horn Island area at about 0720 and the pilot advised air traffic control that he intended holding east of the island due to low cloud and rain. At about 0750 he advised pilots in the area that he was north of Horn Island and was intending to commence a visual approach. When the aircraft did not arrive a search was commenced but the pilot and aircraft were not found. On about 10 October 2011, the wreckage was located on the seabed about 26 km north-north-west of Horn Island.

While taxiing at Papeete-Faaa Airport, the aircraft went out of control and collided with various ground handling equipment such as a catering truck, a belt loader and cargo containers. There were no injuries but the aircraft was damaged beyond repair.

On 20 December 2010, the owner/pilot of a Pacific Aerospace Corporation FU-24-954 Fletcher aircraft, registered VH-FNM, was conducting aerial spreading of urea fertilizer at Wynella Station; a property 40 km south-south-west of Dirranbandi, Queensland. At about 1650 Eastern Standard Time, the pilot was returning to the landing strip after the completion of an application run. The aircraft impacted the terrain, and the pilot was fatally injured.
