• A South Korean audit reveals construction cost-cutting measures contributed to a deadly plane crash.
• The crash involved a Boeing 737-800 that claimed 179 lives, with only two survivors.
• Significant safety concerns were raised regarding the localiser installations at various airports.
• The transport ministry has accepted the findings and pledged stronger safety measures.
• Muan airport remains closed since the incident, with a full investigative report pending.

A recent South Korean audit has reported that the country's transport ministry engaged in cost-cutting practices that compromised aviation safety, particularly following the tragic December 2024 crash of a Jeju Air Boeing 737-800, which resulted in 179 fatalities. The crash occurred at Muan International Airport when the aircraft, struck by birds, belly-landed and overran the runway, colliding with a concrete support for a localiser antenna. The only survivors were two flight attendants situated at the rear of the plane, according to Reuters, South China Morning Post, and Channel News Asia.

The South Korean Board of Audit and Inspection reported that the ministry opted for a 2.4-meter (approximately 8-foot) high concrete embankment to reduce construction costs associated with the localiser system rather than adhering to international safety standards which require such structures to be designed to break apart upon impact. This decision was made without a thorough review of aviation safety regulations, leading to significant oversights across multiple airports, including Muan, Gimhae, and Jeju, reports Reuters and South China Morning Post.

According to the audit findings, the ministry issued approvals for 14 non-compliant localiser installations over a 22-year period, which included incorrectly certified operating permits and inspections that failed to identify violations of frangibility standards. The ministry acknowledged these shortcomings and indicated plans for strict follow-up measures, focusing on localiser system improvements and enhanced bird-strike prevention protocols, as indicated by Reuters, South China Morning Post, and Channel News Asia.

A separate report commissioned by the government concluded that the fatalities in the crash could have been significantly reduced had the localiser system been designed correctly, emphasizing the critical nature of adhering to aviation safety standards. Muan airport has remained closed since the crash, and the release of a comprehensive investigative report continues to be delayed, missing its one-year deadline for progress disclosure, according to Reuters, South China Morning Post, and Channel News Asia.
