Tara Airin Twin Otter katosi tänään aamupäivällä Nepalissa kotimaan lennolla kyydissään yhteensä 22 henkilöä.

Kone on ilmeisesti löytynyt, mutta vielä ei ole tietoa kyydissä olleiden kohtalosta. Huonon sään takia helikopterit joutuivat palaamaan lähtöpaikkaansa.

Airline Operators Association of Nepal (AOAN) has said the missing aircraft of Tara Air has been located in Larjung area of Mustang district.

"We can confirm that the location is near Larjung. But we don't have more details," Yograj Sharma Kandel, the spokesperson of the association, told Himal Press. "Ground forces are heading toward the area. Because of difficult topography, even they are facing difficulty."

Search helicopters sent from Kathmandu and Pokhara have returned due to bad weather. The choppers have been kept on stand-by at Pokhara and Jomsom.

Onnettomuustutkijoiden loppuraportissa todetaan mm., että kone joutui epähuomiossa IMC:hen ja varoitusjärjestelmä TAWS oli kytketty pois päältä eikä niinollen varoittanut miehistöä lähestyvästä maastosta johon kone törmäsi.

Raportti listaa nipun muitakin syitä onnettomuuteen, mm. ohjaamoyhteistyön puutteet ja vakiomenetelmien noudattamattomuuden.

On May 13th 2023 Nepal's AAIC released their final report concluding the probable causes of the crash were:

The probable cause of this accident was the flight crew’s failure to monitor and maintain the proper course while inadvertently flying in IMC conditions with the aircraft Terrain Avoidance and Warning System [TAWS] inhibited which resulted into a CFIT accident.

The contributing factors for the accident are:

1. The flight crew’s failure to follow the SOP of company

2. The aircraft flight operation with TAWS inhibited during deteriorating en-route weather condition.

3. Loss of situational awareness of crew

4. Deteriorating en-route weather

5. Less experienced copilot for that sector and high crew gradient

6. Poor CRM during the flight

7. The whole cockpit duties [both PF and PM] were undertaken by the PIC, which likely impaired his performance.

8. Underutilization of the available Navigation instruments.
