On January 27th, the Air and Railway Accident Investigation Committee of the South Korean Ministry of Land, Infrastructure, Transport and Tourism released the preliminary investigation report on the Jeju Air Flight 2216 crash, restoring the details of the incident. The preliminary investigation report shows that the two “black boxes” on the aircraft involved in the incident stopped recording at 8:58:50 local time on December 29th. The plane crashed into the concrete base of the navigation system antenna after landing on the belly of the plane at high speed at 4:07, causing a violent explosion and burning of the aircraft. The preliminary investigation report shows that when the “black box” of the plane interrupted recording, the plane was approaching runway 01 at Wu’an Airport from south to north at a speed of about 298 kilometers per hour and an altitude of about 151 meters from the ground, preparing to land. At this time, both engines of the plane sucked in the common winter migratory bird “Hua Mian Duck” in South Korea. After the incident, feathers and blood traces of this population of migratory birds were found in both engines. Six seconds after the “black box” stopped recording, the pilot of the aircraft involved in the incident issued a “MAYDAY” distress signal and then raised the altitude to go around. After flying over the left side of the original landing direction for a period of time, he turned right and entered the runway from the other side of the same runway, direction 19. He landed on the belly of the aircraft without lowering the landing gear. The preliminary investigation report did not specify why the landing gear was not lowered during the landing of the aircraft involved in the incident. In addition, the specific time and quantity of the collision between the aircraft and the bird flock, as well as the impact of other bird species and bird flock collisions on the abnormal body of the aircraft, including the “black box” stop recording, are also expected to be explained in the final investigation report of the accident.
