Investigation results of the Jeju Air Disaster: Feathers and bloodstains of a Tomoe duck discovered in the engine

An investigation into the Jeju Airlines passenger plane disaster that occurred at Muan International Airport last month has confirmed that duck feathers and bloodstains were found in both engines.
The Ministry of Land, Infrastructure, Transport and Tourism (equivalent to the Ministry of Land, Infrastructure, Transport and Tourism in Japan) Aviation and Railway Accident Investigation Committee (hereinafter referred to as the Investigation Committee) announced on the 25th that a bird had been sucked into the engine of the passenger plane where the accident occurred.
The company said it had requested a genetic analysis from a domestic specialist institution and found that the bird in question was a Tomoe duck. However, it is unclear whether the duck was sucked into the engine, causing the breakdown.
"At present, it is unclear from the samples found whether the bird population or other species are included," the investigation committee said. "We will continue to confirm the engine condition and investigate the additional
The investigation committee also said, "We are planning to overhaul the engine to collect samples."
"We also confirmed this in the video from CTV," he said. Earlier, experts had suggested that the loss of the last four minutes of the flight recorder's recordings could have been due to a power outage caused by damage to both engines.
In addition, the investigation committee analyzed and re-analyzed the flight recorder (FDR), the cockpit voice recorder (CVR), and air traffic control communication records.
The video was compiled and released in seconds, showing the situation just before the collision. According to the video, the aircraft first communicated with the airport control tower at 8:54:43 a.m. on the 29th of last month, for the first time, to prepare for landing.
The aircraft was cleared to land on the runway in the opposite direction. At 8:57:50, the control tower sent a "bird activity alert" to the aircraft, and at 8:58:11, the captain and co-pilot warned the aircraft about bird-related
The recording from 8:58:50 showed that both the FDR and CVR had been lost. This was presumably due to the impact of the collision with the bird making it impossible to provide power to the aircraft.
The investigation committee plans to continue analyzing the overall operation of the aircraft through detailed examination of the wreckage and review of flight records. If emergency safety measures are required, it will immediately issue safety advice to airlines.
The investigation committee said it plans to "analyze every detail one by one based on information collected by each group, including flight operations and maintenance, and will carry out a thorough investigation."
"We will do our utmost to investigate and determine the exact cause of the accident."
