The joint investigation team of South Korea and the United States, which is probing the Jeju Air disaster, will begin examining the condition of the wrecked aircraft and its engine on Wednesday.

The Ministry of Land, Infrastructure and Transport said during a briefing earlier in the day that two additional U.S. investigators have joined the team, bringing the total number of American investigators to ten.

The U.S. team includes representatives from the National Transportation Safety Board(NTSB), the Federal Aviation Administration(FAA), and the aircraft manufacturer Boeing, and is composed of experts in various fields.

Starting Wednesday, the joint team will conduct a visual inspection of the wreckage, including the aircraft, engine and bird strike marks.

Additionally, the transport ministry revealed that, as part of the investigation, it is examining the materials of navigation safety facilities, including localizers such as the one that collided with the ill-fated Jeju Air passenger aircraft, at airports nationwide.
