The aircraft entered the Venezuelan airspace without flight plan and authorisation. While flying over the Paraguaña Peninsula at low altitude, the crew was forced to land when control was lost. The aircraft crashed in shallow water few meters offshore, lost its tail and both wings. Both pilots were killed.

The twin engine aircraft departed Puerto Plata-Gregorio Luperón Airport at 1718LT on a flight to Santa Cruz de Barahona. En route, the pilot was informed that this airport is closed to all traffic after 1700LT and decided to return to Puerto Plata. A last radio communication was recorded with ATC when the aircraft disappeared from radar screens eight minutes later. Dominican authorities thought the aircraft may have crashed in the septentrional mountain range and SAR operations were initiated. Few hours later, the wreckage was found in a marshy area of the Lake Maracaibo, more than 1,000 km south of Puerto Plata. All three occupants were found alive and arrested while the aircraft was damaged beyond repair. Venezuelan authorities reported the aircraft and its occupants were engaged in an illegal narcotic flight.

The float-equipped De Havilland DHC-2 was on a tour flight, and the Cessna 206 was on a personal flight. The airplanes collided in midair over a lake during day visual meteorological conditions. No radar or automatic dependent surveillance-broadcast data were available for either airplane. Witnesses reported that the airplanes were flying directly toward each other before they collided about 700 to 800 ft above the water. Other witnesses reported that the Cessna was at a lower altitude and had initiated a climb before the collision. Review of 2 seconds of video captured as part of a witness’ “live” photo showed that both airplanes appeared to be in level flight before the collision. No evidence of any preexisting mechanical malfunction was observed with either airplane. Recovered wreckage and impact signatures were consistent with the upper fuselage of the Cessna colliding with the floats and the lower fuselage of the De Havilland. The impact angle could not be determined due to the lack of available evidence, including unrecovered wreckage. The available evidence was consistent with both pilots’ failure to see and avoid the other airplane.

On May 28, 2020, about 1600 Alaska daylight time, an Aero Commander 500S airplane, N909AK sustained substantial damage when it was involved in an accident near Aniak, Alaska. The pilot and three passengers sustained serious injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 public aircraft flight. The airplane was owned by the State of Alaska and operated by the Division of Forestry. According to the pilot, after arriving in Aniak, he had the local fuel vendor's ground service personnel refuel the airplane. He then signed the fuel receipt, and he returned to the airplane's cockpit to complete some paperwork before departure. Once the paperwork was complete, he then loaded his passengers, started the airplane's engines, and taxied to Runway 29 for departure. The pilot said that shortly after takeoff, and during initial climb, he initially noticed what he thought was mechanical turbulence followed by a reduction in climb performance, and the airplane's engines began to lose power. Unable to maintain altitude and while descending about 400 ft per minute, he selected an area of shallow water covered terrain as an off-airport landing site. The airplane sustained substantial damage during the landing. The fueler reported that he was unfamiliar with the airplane, so he queried the pilot as to where he should attach the grounding strap and the location of the fuel filler port. Before starting to refuel the airplane, he asked the pilot "do you want Prist with your Jet" to which the pilot responded that he did not. After completing the refueling process, he returned to his truck, wrote "Jet A" in the meter readings section of the prepared receipt, and presented it to the pilot for his signature. The pilot signed the receipt and was provided a copy. The fueler stated that he later added "no Prist" to his copy of the receipt, and that he did not see a fuel placard near the fueling port. A postaccident examination revealed that the reciprocating engine airplane had been inadvertently serviced with Jet A fuel. A slightly degraded placard near the fuel port on the top of the wing stated, in part: "FUEL 100/100LL MINIMUM GRADE AVIATION GASOLINE ONLY CAPACITY 159.6 US GALLONS."

On 12 May 2020, a Quest Kodiak 100 aircraft, registration PK-MEC, was being operated by Mission Aviation Fellowship (MAF) as a cargo flight from Sentani Airport (WAJJ), Jayapura, Papua with intended destination of Mamit Airstrip (WAVS) Tolikara, Papua. The pilot was the only person on board for this flight and the aircraft carried 694 kgs of cargo goods. At 0622 LT (2122 UTC), the pilot of PK-MEC aircraft requested clearance to the Sentani Tower controller to start aircraft engine and flying to Mamit at radial 241° with intended cruising altitude 10,000 feet. The Sentani Tower controller approved the request. At 0627 LT, on daylight condition, the aircraft took off from runway 12 of Sentani Airport, thereafter, the Sentani Tower controller advised to the pilot of PK-MEC to contact Jayapura Radar controller. At 0628LT, the pilot of PK-MEC declared “MAYDAY” on Jayapura Radar radio frequency. The Jayapura Radar controller tried to contact pilot of PK-MEC four times but no answer. At 0630 LT, the Jayapura Radar Controller requested the pilot of PK-RCE that was just took off from Sentani to visually observe the position of PK-MEC aircraft. Few minutes later, the pilot of PK-RCE reported to Jayapura Radar controller that some debris were seen on Sentani Lake and some boats were moving toward the debris location. The pilot of PK-RCE assumed that PK-MEC aircraft had crashed to the lake. The pilot fatally injured. The wreckages have been recovered including the Global Positioning System (GPS) data card.

While the pilot was on a visual approach to the airport and descending over water on the left base leg, about 100 ft above the water's surface, the airplane entered instrument meteorological conditions with no forward visibility. The pilot looked outside his left window to gauge the airplane's altitude and saw "black waves of water approaching extremely rapidly." He tried to pull back on the yoke to initiate a climb, but the nosewheel contacted the water. Subsequently, the airplane nosed over and came to rest inverted in the water. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

According to the pilot, when the airplane’s airspeed reached about 90 knots during the takeoff roll, he applied back pressure to the control yoke to initiate the takeoff and noted a brief positive rate of climb followed by a sinking sensation. The airspeed rapidly decayed, and the stall warning horn sounded. To correct for the decaying airspeed, he lowered the nose then pulled back on the airplane’s control yoke and leveled the wings just before impacting the ocean. The pilot stated there were no pre accident mechanical malfunctions or anomalies that would have precluded normal operation. Wind about the time of the accident was recorded as 110º downwind of the airplane at 15 knots gusting to 28 knots. The passengers recalled that the pilot’s preflight briefing mentioned the downwind takeoff but included no discussion of the potential effect of the wind conditions on the takeoff. The airplane’s estimated gross weight at the time of the accident was about 769.6 pounds over its approved maximum gross weight, and the airplane’s estimated center of gravity was about 8.24 inches beyond the approved aft limit at its maximum gross weight. It is likely that the pilot’s decision to takeoff downwind and operate the airplane over the maximum gross weight with an aft center of gravity led to the aerodynamic stall during takeoff and loss of control. Downwind takeoffs result in higher groundspeeds and increase takeoff distance. While excessive aircraft weight increases the takeoff distance and stability, and an aft center of gravity decreases controllability. Several instances of the operator’s noncompliance with its operational procedures and risk mitigations were discovered during the investigation, including two overweight flights, inaccurate and missing information on aircraft flight logs, and the accident pilot’s failure to complete a flight risk assessment for the accident flight. The operator had a safety management system (SMS) in place at the time of the accident that required active monitoring of its systems and processes to ensure compliance with internal and external requirements. However, the discrepancies noted with several flights, including the accident flight, indicate that the operator’s SMS program was inadequate to actively monitor, identify, and mitigate hazards and deficiencies.

The four engine airplane departed Santiago de Chile at 1021LT and landed at Punta Arenas for a technical stop at 1444LT. It took off at 1653LT on a leg to Teniente Rodolfo Marsh-Presidente Eduardo Frei Montalva Airport located on King George Island, Antarctica, carrying 21 passengers and 17 crew members. After flying a distance of about 390 NM, while in cruising altitude, the radar contact was lost, vertical to the Drake Passage. SAR operations were initiated jointly by the Chilean, Uruguay and Argentine Air Forces which dispatched several aircraft over the area. Two days later, debris were found floating on water. It seems that none of the 38 occupants survived the crash.

At approximately 0745 Central Daylight Time on 26 October 2019, the Blue Water Aviation float-equipped deHavillandDHC-3 Otteraircraft (registration C-GBTU, serial number 209) departed Bissett Water Aerodrome, Manitoba, with the pilot, 2 passengers, and approximately 800 pounds of freight on board. The destination was Little Grand Rapids, Manitoba, on the eastern shore of Family Lake. At approximately 0845, while on approach to Family Lake, the aircraft’s right wing separated from the fuselage. The aircraft then entered a nose-down attitudeand struck the water surface of the lake. The pilot and the 2 passengers were fatally injured. The aircraft was destroyed by impact forces. The emergency locator transmitter activated momentarily.

En route from Durango to Acapulco, the twin engine airplane crashed in unknown circumstances in the Infiernillo River, in the region of Las Juntas. The wreckage was found inverted and partially submerged in water. All six occupants were killed.
