The aircraft was engagted in an illegal contraband flight when it crash landed in an open field located near Ahuas. No one was found on site and the aircraft was damaged beyond repair. A load of cocaine was found on board.

According to the pilot, he and the copilot were flying low-level mapping flights in the twin-engine airplane. Although the copilot was not multi-engine rated, he and the pilot regularly switched control of the airplane during the mapping flights. On the accident flight, the pilot was seated in the right seat; the copilot was seated in the left seat; and they were flying the airplane at an altitude of about 300 ft above ground level. According to the pilot, they flew for about 2 hours before he, who was the pilot flying at the time, switched fuel tanks from the inboard tanks to the outboard tanks. The pilot did not tell the copilot he had switched fuel tanks. About 1.5 hours later, while the copilot was the pilot flying, the left engine started to surge and lose power. The pilot began the steps of the emergency procedure for an engine failure in cruise flight starting with moving the fuel selectors to the inboard tanks. Power was not restored; the airplane immediately began losing altitude; and the pilot took over control of the airplane. The copilot stated that at the time the pilot took over control, he looked at the fuel tank quantity gauges, and they both displayed zero. The pilot reported that the airplane stalled just above the ground during the emergency landing in a field. The right wing struck first, and within a couple of seconds, the right outboard fuel tank exploded. The pilot and copilot egressed out the rear door. Examination of the wreckage revealed that neither engine exhibited evidence of power at impact. The left outboard fuel tank was found completely full of fuel, and the left inboard fuel tank was empty. Both right wing tanks were fire damaged, and the fuel quantity in the tanks at impact could not be determined. Further examination revealed that the fuel crossfeed valve was in the “crossfeed/open” position. No fuel was observed in the valve or attached fuel lines during disassembly. The left fuel selector valve was found in the “OFF” position, and no fuel was observed within the fuel line between the valve and gascolator. The right fuel selector valve was damaged by fire, and its position at impact could not be determined. No other anomalies were noted in the engines or airframe. According to the pilot, all fuel tanks were full before the flight. According to the pilot’s operating manual, the airplane likely consumed about 33.1 gallons of fuel per hour or a total of about 115 gallons of fuel during the 3.5-hour flight. Given that the inboard fuel cells held 56 gallons each (112 gallons total), that the left inboard tank was found empty, and that the copilot noticed that the fuel gauges were reading zero just before impact, it is likely that each engine was drawing fuel from its respective inboard tank throughout the flight until those tanks were empty. The left engine lost power first, and the right engine likely lost power just before impact. The postaccident positions of the crossfeed valve (on) and the left fuel selector (off) did not correspond to the pilot’s statements regarding his positioning of the fuel selector valves during the flight. The fuel panel was located between and behind the pilots’ seats and required the pilots to look down and back in order to see the panel when making changes to the panel; therefore, it is likely the pilot misconfigured the valves when he switched tanks 2 hours into the flight, when he switched tanks after the left engine lost power, or on both occasions. It is unlikely the copilot would have been able to see an incorrect switch selection on the fuel panel due to the location of the panel, and he would have been unlikely to look at the 2-hour point as the pilot did not verbalize that a change to the panel had been made.

On July 31, 2020, about 0827 Alaska daylight time, a de Havilland DHC-2 (Beaver) airplane, N4982U, and a Piper PA-12 airplane, N2587M, sustained substantial damage when they were involved in an accident near Soldotna, Alaska. The pilot of the PA-12 and the pilot and the five passengers on the DHC-2 were fatally injured. The DHC-2 was operated as a Title 14 Code of Federal Regulations (CFR) Part 135 on-demand charter flight. The PA-12 was operated as a Title 14 CFR Part 91 personal flight. The float-equipped DHC-2, operated by High Adventure Charter, departed Longmere Lake, near Soldotna, about 0824 bound for a remote lake on the west side of Cook Inlet. The purpose of the flight was to transport the passengers to a remote fishing location. The PA-12, operated by a private individual, departed Soldotna Airport, Soldotna, Alaska, (PASX) about 0824 bound for Fairbanks, Alaska. Flight track data revealed that the DHC-2 was traveling northwest about 78 knots (kts) groundspeed and gradually climbing through about 1,175 ft mean sea level (msl) when it crossed the Sterling Highway. The PA-12 was traveling northeast about 1,175 ft msl and about 71 kts north of, and parallel to, the Sterling Highway. The airplanes collided about 2.5 miles northeast of the Soldotna airport at an altitude of about 1,175 ft msl. A witness located near the accident site observed the DHC-2 traveling in a westerly direction and the PA-12 traveling in a northerly direction. He stated that the PA-12 impacted the DHC-2 on the left side of the fuselage toward the back of the airplane. After the collision, he observed what he believed to be the DHC-2's left wing separate, and the airplane entered an uncontrolled, descending counterclockwise spiral before it disappeared from view. He did not observe the PA-12 following the collision.

On 26 July 2020, at 12:46 local time (02:46 UTC), a Cessna 402C aircraft, registered VH-TSI collided with trees during an aborted take-off at an uncommissioned field near Papa-Lealea, about 16 nm North-West of Port Moresby, Papua New Guinea. The pilot, during interview with the AIC, stated that he departed at 09:30 that day from Mareeba Airport, Queensland Australia and tracked towards the North North-East with a planned track set slightly left of Jacksons International Airport, Port Moresby, National Capital District, Papua New Guinea. As the aircraft neared the Southern shoreline (within the Caution Bay area), he diverted left and began tracking towards the North West along the coast in order to avoid flying over villages in the area. He subsequently crossed over land before turning back to approach the intended landing field. As the aircraft approached to land, the outboard section of the left wing was clipped by a tree and separated from the aircraft. According to the pilot, he continued on with the approach and landed on the field at about 12:20. The pilot reported that he had flown to and within Papua New Guinea in the past and was familiar with the area and airspace. He confirmed that after departing Mareeba, he switched off the transponder. After shutting down the aircraft, the aircraft was refuelled with jerrycans full of fuel (AvGas) and loaded with cargo by persons waiting on the ground. The pilot reported that he estimated that a distance of 800 m would be required for the take-off. According to the pilot, at about 12:40, he lined up and commenced his take-off roll from the Southern end of the field. As the aircraft lifted off, he noticed that the airspeed indicator (ASI) was not working. He also observed that the aircraft was not achieving a positive rate of climb. He subsequently pulled the throttles back and manoeuvred the aircraft back towards the ground. The aircraft touched down with a speed that the pilot described as higher than normal, with about 400 m of usable field remaining. The aircraft continued off the end of the field and into the bushes clipping trees along the way until it came to rest. The pilot informed the AIC that he was the sole occupant of the aircraft, and sustained minor injuries as a result of the occurrence. The aircraft was substantially damaged. The investigation confirmed that the fire to the left wing and engine was a post-accident event and was deliberate. The pilot was later arrested and a load of 500 kilos of cocaine distributed in 28 bales was found at the scene.

Engaged in an illegal flight, the twin engine airplane landed on a dirt road located about 35 km southwest of Brus Laguna. The nose gear collapsed and the aircraft came to rest, damaged beyond repair. No one was found on site and a load of 806 kilos of cocaine was seized.

The crew was completing a spraying mission near the village of Kistenovo, about six km north of Bol'shoye Boldino Airfield. While flying at a low height against sunrise, the crew failed to see and avoid power cables. The single engine airplane collided with cables and a concrete post before crashing in a cornfield, bursting into flames. The copilot was killed and the captain was seriously injured. He died two days later from his injuries. The aircraft was destroyed by a post crash fire.

The crew was engaged in an illegal trip and elected to land on a remote 'airstrip' located in the region of Machiques. The aircraft crash landed and came to rest, bursting into flames. One pilot was killed and the second was injured.

The pilot, sole on board, departed Příbram Airport in the early afternoon on a private flight to Moravská Třebová. About 15 minutes into the flight, while cruising in good weather conditions, he encountered engine problems and elected to divert to Benešov Airfield. Shortly later, some cooling liquid leaked from the engine into the cabin and on the windshield, reducing the pilot's vision. He elected to make an emergency landing in a cornfield when, upon touchdown, the aircraft crashed and came to rest upside down with its right wing torn off. There was no fire. The pilot was injured and the aircraft was damaged beyond repair.

Before the personal instrument flight rules flight began, the pilot obtained a preflight weather briefing that indicated that instrument meteorological conditions, convective activity, and moderate-to-severe icing conditions would be occurring along the route of flight. According to track data, while the pilot was navigating to avoid weather, the pilot was using the autopilot for maneuvering. After the pilot reported to air traffic control that the airplane would be turning direct to its destination, the performance analysis of track data showed that the airplane began a slight left turn with a bank angle of about 10°, which was consistent with the intended route of flight. However, the turn then reversed, and the airplane began banking to the right, reaching about 120° right wing down during the next 70 seconds and showing a slow oscillation in pitch attitude. Satellite imagery showed that the airplane was likely in instrument meteorological conditions when it began a rapid descent, and the airplane’s descent rate was about 7,000 feet per minute. Postaccident examination of the airplane and right engine (the left engine was not recovered) revealed no evidence of any preimpact mechanical malfunctions or failures that would have precluded normal operation. The dynamics of the airplane’s movements after the right turn began indicated that the airplane likely was not being actively controlled when it diverted from the intended flightpath. The circumstances of this accident were thus consistent with the pilot’s lack of timely recognition that the autopilot was disengaged. The available evidence for this accident precluded a determination of where the pilot’s attention was directed while navigating direct to the destination. However, the turbulence would have increased the pilot’s workload, and the restricted visibility conditions would have prevented the pilot’s use of outside cues to detect deviations in the airplane’s attitude. Also, the initial roll rates might not have been sufficient to provide reliable cues to the pilot of the developing bank, and the convective conditions would likely have made it difficult for the pilot to detect and recover from the fully developed unusual attitude.

The airplane landed on an illegal airstrip, lost its nose gear and hit obstacles before coming to rest. No one was found on site. The aircraft was damaged beyond repair.
