Nepal has decided to send the ‘black box’ of Yeti Airlines Flight 691, which crashed in Pokhara last week, to Singapore.

All 72 people on board were killed when the plane crashed minutes before landing at the new international airport in Pokhara, on January 15.

Officials say one body is still unaccounted for.

Buddhi Sagar Lamichhane, joint secretary at the Tourism Ministry, said three members of the investigation commission would take the black box to the Transport Safety Investigation Bureau, a statutory board under the Ministry of Transport of Singapore.

The black box contains two types of recording devices—flight data recorder (FDR) and cockpit voice recorder (CVR).

A flight recorder, popularly known as black box, is an electronic recording device placed in an aircraft for the purpose of facilitating the investigation of aviation accidents and incidents.

They are painted in bright orange and are kept in the aircraft’s tail section, where it is more likely to survive a crash.

“We are departing to Singapore on Friday. It will take at least a week for the examination of the CVR and FDR,” said Lamichhane, the member secretary of the commission, who is also in the team.

FDR preserves the engine sounds, instrumental warnings and other audio recordings during the flight while CVR preserves the sounds in the cockpit, including the conversation of the pilots.

CVR records the signals of the microphones and earphones of the pilots’ headsets and the cockpit.

According to Lamichhane, they decided to take the black box to Singapore as the two countries have a memorandum of understanding to assist in the field of aviation.

“The examination of the black box in Singapore is free of cost,” said Lamichhane.

According to officials, of the 72 people, the bodies of 60 people have already been handed over to the family.

Twenty-two bodies were handed over in Pokhara and the remaining were flown to Kathmandu on January 18 to carry out further investigation and postmortem.
