Singapore’s Transport Safety Investigation Bureau ( TSIB ), an arm of the Transport Ministry, is opening an investigation into what happened on SQ321.
It claims to have spoken with its Thai peers and will give detectives there.
The helicopter encountered” immediate severe volatility” as it approached the Irrawaddy Basin at 37, 000 feet, according to SIA. This took position 10 days after withdrawal from Heathrow.
The pilot then declared a medical emergency and flew the aircraft to Bangkok, where it made its first landing at Suvarnabhumi Airport at 3.45pm local time ( 4.45pm Singapore time ).
According to a customer on the trip, the incident involved feeling as though something was rising and falling.
Dzafran Azmir, a 28-year-old scholar on the trip, reported to Reuters that the aircraft immediately began to tilt upward and there was shaking.” Unavoidably, there was a very serious fall, and everyone seated and not wearing a seatbelt was launched quickly into the ceiling,” Azmir said.
Some people “hit their mind on the bag cabins aloft and dent it,” he said,” and then smash through it right into the areas where lamps and faces are.”
Kittikachorn, the Thai airport standard, said most of the people he had spoken to had been wearing their cars.
