Dior Chandra Lal Kana, spokesman for the Civil Aviation Authority of Nepal (CAAN), said: "Rescuers have recovered all 22 bodies from the crash site. Now there is nothing left at the crash site except the wreckage of the plane. All the bodies and black boxes have been found. ”

Local rescue teams recovered 21 bodies from the wreckage of victims scattered along a steep slope on May 30. Yesterday the last body was recovered.

On Sunday morning, 22 people reached a Canadian dhha-6-300 twin otter that crashed 15 minutes after taking off from the tourist town of Pokhara, 125 kilometers west of Kathmandu. Modern aircraft are also fitted with two "black boxes" – a flight data recorder and a cockpit voice recorder.

This is a short regional flight operated by Tara Airlines, which was scheduled to fly to the famous tourist destination of Jomson, 80 km away. Nepal's record in aviation safety is inherently poor, and the route is even more accident-prone. According to the Nepal Times, since 1997, there have been five fatal air crashes, resulting in 74 people killed on the route.

Local Nepalese officials said they sent the remains of 10 victims to Kathmandu on Monday and the remaining 12 bodies on Tuesday, saying: "The bodies will be taken to the Tribhuvan University Teaching Hospital for autopsy and handed over to families after identification."

Nepal police said that due to bad weather and difficult terrain, the rescue work took longer than expected.

The aircraft involved was a De Havilland Canada DHC-6 Twin Otter 300 registered number 9N-AET, a 19-seat short take-off and landing (STOL) general aviation aircraft. De Havilland Canada/Viking Airlines was developed in the 1960s, first flew on 20 May 1965, and has produced 985 aircraft since 1965.

The Twin Otter aircraft adopts a fixed landing gear design, with short field take-off and landing and high climb rate capabilities, which can be widely used in freight, regional transportation and medical aircraft, in addition to geographical mapping, high-altitude skydiving activities, and can also be seen in multinational armies.

On March 12, 2018, a U.S.-Bangladesh Airlines Flight 211 from Dhaka to Kathmandu crashed and caught fire while landing, killing 51 of the 71 people on board. The aircraft operating the route was the Bombardier Q400, which carried 71 people, including 67 passengers and four crew members.

At the time of the accident, it was the deadliest air disaster involving Bangladesh Airways and the deadliest involving a Bombardier Q400 aircraft. The accident investigation showed that the cause of the accident was the pilot's operational error and loss of situational awareness, which led to the crash.

On September 28, 1992, an Airbus A320 of Pakistan International Airlines, while flying PK268 from Jinnah International Airport to Kathmandu Tribhuvan International Airport, pilots attempted to crash into a mountain during a landing in Kathmandu, killing all 167 people on board. The accident investigation showed that the cause of the accident was the pilot's operation error, which led to the occurrence of a controlled flight hitting the ground.

The Nepalese authorities have also set up a team to investigate the crash, which will also contain information on accident prevention.
