De Havilland DHC-2 Beaver

The single engine airplane crashed in unknown circumstances in the early morning in Red Lake. Among the five occupants, two occupants were seriously injured and three others suffered minor injuries.

The single engine airplane was conducting a visual flight rules repositioning flight from Louie Bay on Nootka Island, British Columbia (BC), to Gold River Water Aerodrome (CAU6), BC, with only the pilot on board. On arrival at CAU6, the pilot noted a rough sea state in the company’s primary landing area and elected to land in the secondary area, a tree-lined river to the east of the base. The aircraft was observed overflying the company dock to the north and then turning right, aligning with the southwest direction of the river. When descending on the alignment turn to final approach, the aircraft experienced an uncommanded yaw and roll. It
abruptly turned further right, heading west, and continued to descend toward the trees. It was reported that opposite aileron input, to try and arrest the uncommanded yaw and roll, increased the roll rate. At approximately 1720, the aircraft struck the forested area on the west side of the river, coming to rest approximately 75 feet from the river. There was no post-impact fire. The pilot received serious injuries, was extracted by local firefighting personnel, and attended to by local paramedics. He was then airlifted to hospital by a search and rescue helicopter.

The pilot reported that, he was departing in the float-equipped airplane in strong gusty wind conditions. After accelerating on the water for about 3 seconds, the airplane suddenly became airborne and crabbed into the wind about 60° to 90° from the intended takeoff path and started to climb as it continued to track away from the intended flight path. As the climb continued, the airplane stalled and impacted the water in a nose low attitude which resulted in substantial damage to the wings and fuselage. The pilot reported that there were no preaccident mechanical malfunctions or anomalies that would have precluded normal operation.

The accident flight was the pilot’s second passenger sightseeing flight of the day that overflew remote inland fjords, coastal waterways, and mountainous, tree-covered terrain in the Misty Fjords National Monument. Limited information was available about the airplane’s flight track due to radar limitations, and the flight tracking information from the airplane only provided data in 1-minute intervals. The data indicated that the airplane was on the return leg of the flight and in the final minutes of flight, the pilot was flying on the right side of a valley. The airplane impacted mountainous terrain at 1,750 ft mean sea level (msl), about 250 ft below the summit. Examination of the wreckage revealed no evidence of pre accident failures or malfunctions that would have precluded normal operation. Damage to the propeller indicated that it was rotating and under power at the time of the accident. The orientation and distribution of the wreckage indicated that the airplane impacted a tree in a left-wing-low attitude, likely as the pilot was attempting to maneuver away from terrain. Review of weather information for the day of the accident revealed a conditionally unstable environment below 6,000 ft msl, which led to rain organizing in bands of shower activity. Satellite imagery depicted that one of these bands was moving northeastward across the accident site at the accident time. Federal Aviation Administration (FAA) weather cameras and local weather observations also indicated that lower visibility and mountain obscuration conditions were progressing northward across the accident area with time. Based on photographs recovered from passenger cell phones along with FAA weather camera imagery, the accident flight encountered mountain obscuration conditions, rain shower activity, and reduced visibilities and cloud ceilings, resulting in instrument meteorological conditions (IMC) before the impact with terrain. The pilot reviewed weather conditions before the first flight of the day; however, there was no indication that he obtained updated weather conditions or additional weather information before departing on the accident flight. Based on interviews, the accident pilot landed following the first flight of the day in lowering visibility, ceiling, and precipitation, and departed on the accident flight in precipitation, based on passenger photos. Therefore, the pilot had knowledge of the weather conditions that he could have encountered along the route of flight before departure. The operator had adequate policies and procedures in place for pilots regarding inadvertent encounters with IMC; however, the pilot’s training records indicated that he was signed off for cue-based training that did not occur. Cue-based training is intended to help calibrate pilots’ weather assessment and foster an ability to accurately assess and respond appropriately to cues associated with deteriorating weather. Had the pilot completed the training, it might have helped improve his decision-making skills to either cancel the flight before departure or turn around earlier in the flight. The operator’s lack of safety management protocols resulted in the pilot not receiving the required cue-based training, allowed him to continue operating air tours with minimal remedial training following a previous accident, and allowed the accident airplane to operate without a valid FAA registration. The operator was signatory to a voluntary local air tour operator’s group letter of agreement that was developed to improve the overall safety of flight operations in the area of the Misty Fjords National Monument. Participation was voluntary and not regulated by the FAA, and the investigation noted multiple instances in which the LOA policies were ignored, including on the accident flight. For example, the accident flight did not follow the standard Misty Fjords route outlined in the LOA nor did it comply with the recommended altitudes for flights into and out of the Misty Fjords. FAA inspectors providing oversight for the area reported that, when they addressed operators about disregarding the LOA, the operators would respond that the LOA was voluntary and that they did not need to follow the guidance. The FAA’s reliance on voluntary compliance initiatives in the local air tour industry failed to produce compliance with safety initiatives or to reduce accidents in the Ketchikan region.

On 12 July 2021 at about 1245 (1545) a Viking Air Ltd DHC-2 Beaver MK1A aircraft registration 5Y-BCL operated by the Desert Locust Control Organization of Eastern Africa (DLCO-EA) with three on board crashed at Kosovo area of Ndabibi in Naivasha, Nakuru County. The accident site is located near the edge of the hilly eastern side of Eburru forest manned by the Kenya Forest Service (KFS). The flight originated from Wilson airport, Nairobi County and was enroute to Lodwar airport, Turkana County. The aircraft was destroyed by impact forces and largely consumed by the ensuing fire. A passenger suffered fatal injuries while the pilot and the other passenger suffered serious injuries requiring more than 48 hours of hospitalization. At the time of the accident the area in the vicinity of the accident site had near overcast cloudy conditions.

The intention of the flight was to drop eight parachutists from an altitude of 1,500 metres. It was the twelfth and planned to be the last flight of the day. The weather conditions were good. The parachutist bench to the right of the pilot had been replaced with a pilot's seat to distance the parachutists from the pilot as a Covid-19 precautionary measure. The pilot had no ability to perform a mass and balance calculation with the available information. After take-off, the aircraft climbed to an altitude of 400 to 500 feet above ground before changing course 180 degrees to the left. The aircraft turned around quickly in a descending turn with a high bank angle. During the final phase, the aircraft dived steeply and then slightly levelled off before impact. Upon impact, the landing gear was teared off, after which the aircraft skidded on its belly 48 metres straight ahead and caught fire. All nine persons on board sustained fatal injuries.

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.

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.

The airplane departed Rahim Yar Khan-Sheikh Zayed Airport and was spraying pesticide in the area to tackle another wave of locust attacks, which began in December 2019, on the request of the district administration. In unknown circumstances, the single engine airplane went out of control and crashed in a sandy area located in Sadiqabad, killing both crew members, a pilot and a flight engineer. They were completing a mission on behalf of the Department of Agriculture of Pakistan. Initial investigations suggest the plane crashed due to a technical fault.
