2010 Tara Air Twin Otter crash

On 15 December 2010, a DHC-6 Twin Otter passenger aircraft of Tara Air crashed shortly after take-off on a domestic flight from Lamidanda to Kathmandu, Nepal. The wreckage of the aircraft was found in Bilandu forest near the village of Shreechaur the morning after the crash. All 19 passengers and three crew aboard were killed in the crash.

Accident
The location of the crash in Shreechaur/Bilandu, Okhaldhunga District, Nepal

Five minutes after taking off from Lamidanda Airport at 15:08 local time,[2] the left wing of the aircraft impacted land and the DHC-6 crashed. The aircraft was reportedly scheduled to land in Kathmandu at around 15:35, 35 minutes after departure.[3] All 19 passengers and three crew members aboard were killed in the crash.[2]

There was initial speculation that bad weather caused the crash. The chief executive of Tara Air, Vijay Shrestha, said: "It showed poor visibility at different levels of the atmosphere. Thick haze at lower levels and as thick a cloud higher up could have caused poor visibility."[4] There was also speculation that the aircraft could have been overloaded, but Shrestha refuted these allegations. "The aircraft's maximum take-off weight is 12,500 pounds, while the Twin Otter's take-off weight that crashed killing all 22 on board was 12,280 pounds," he said. "So it was underweight by 220 pounds, the allegation is wrong."[5]

Aircraft

The aircraft involved was a DHC-6 Twin Otter bearing the registration 9N-AFX. It was built by de Havilland Canada in 1984 and was operated by several American airlines before it was introduced to Nepal in 2000, when Shangri-La Air purchased the aircraft. In 2010, just shortly before the accident, Tara Air purchased the aircraft.[6][7]

Search operation

Helicopters searched for the wreckage of the aircraft on the day of the crash, but were called off during the night because of poor visibility, even though night vision equipment was installed on board. The day after the crash, the Nepalese Army located the wreckage in Okhaldhunga, Nepal, at an altitude of approximately 2,700 metres (8,900 ft). All 22 bodies were recovered.[8] The wreckage of the aircraft reportedly covered 200 square metres (2,200 sq ft), and, according to a police spokesperson, had "broken up completely".[9]

Investigation

An investigation into the crash was launched after the accident site was located. Nepal's Ministry of Tourism and Civil Aviation formed a group of five investigators to find the cause of the crash. The five were ordered to present a report on the accident by 90 days after the crash occurred.[10] The cockpit voice recorder was recovered from the scene of the accident.[11]

A separate investigation was also started into alleged irregularities, which, according to The Himalayan Times included "carrying passengers by issuing tickets in other's name, not verifying identity while checking-in passengers and the process of immigration of the foreign nationals who lost their lives in the crash."[10] Police arrested the general manager of a travel agent based in Kathmandu over suspicions of tax evasion during the sale of tickets for the flight.[12]

gollark: If you want "simple", how about, I don't know, lisp?
gollark: "Costless" how?
gollark: I'd partly agree, but that doesn't mean ALL ABSTRACTION is hard to use.
gollark: If we accept your ridiculous "simple to implement means easy" thing, then machine code is easier than assembly, and... CPU microcode? is easier than machine code.
gollark: Assembly is an abstraction over machine code.
