Teams from United States-based aircraft company Boeing and the US government are on the way to Indonesia to join the investigation into the plane crash involving a Boeing 737 Max 8 belonging to Lion Air, the National Transportation Safety Commission (KNKT) said on Tuesday.

They are slated to arrive on Wednesday.

The teams will join the national team and a team from Singapore that arrived on Monday evening. KNKT flight accident investigator Ony S. Wibowo said Argentina, Malaysia and Saudi Arabia, had also offered their help in search and investigation.

The team from the US government consists of personnel from the US National Transportation Safety Board (NTSB).

“A technician and engineer will come from Boeing, they will be accredited representatives in the investigation,” he said. Ony added that at least 10 people would join the investigation team.

The team from Singapore consists of three personnel who will focus on helping to find the aircraft’s flight recorder, or black box. They will be equipped with a hydrophone that can help detect the sound of an Underwater Locator Beacon (ULB) that is attached to the black box. 

“This [ULB] is the thing we are searching for. Hopefully the ULB has not become separated from the black box. If we know where the black box is, we hope the plane body will be nearby,” said Ony. (evi)
