Jeju Air crash probe confirms bird strike led to fatal Boeing accident

The pilots identified a flock of birds during their approach to runway 01. A distress call was made following a bird strike during an attempted go-around. Security footage confirmed proximity to birds during this maneuver.

"Both engines were examined, and feathers and bird blood stains were found on each," said ARAIB. Samples were analyzed and identified as belonging to Baikal Teals, migratory birds present in South Korea during winter.

This preliminary report indicates ongoing investigations involving engine teardown and analysis of CVR/FDR data. "These all-out investigation activities aim to determine the accurate cause of the accident," ARAIB stated.

Assistance is being provided by international bodies such as the National Transportation Safety Board (NTSB) and France's Bureau d'enquêtes et d'analyses pour la sécurité de l'aviation civile (BEA).

Further details reveal that the aircraft involved was manufactured in 2009 by Boeing for Ryanair before entering service with Jeju Air in 2017. Past amendments by the Federal Aviation Administration (FAA) have addressed CVR and FDR reliability issues following previous accidents where insufficient data hampered investigations.

"By January 1, 2005," states FAA guidelines, "retrofit all airplanes that are required to carry a CVR and an FDR with a CVR that […] is fitted with a 10-minute independent power source."

Boeing proposed changes apply globally; however, economic constraints prevent mandatory retrofits for existing aircraft systems outside US jurisdiction.

Park Sang-woo, South Korea's Transport Minister, announced his resignation amid ongoing responses to this crisis.
