International Aviation Safety Guidelines Regarding Navigation Structures Were Ignored at Muan Airport

International aviation safety guidelines dictate that navigation structures, such as localisers, should be constructed from frangible, or breakable, materials. However, at Muan International Airport, these critical localiser systems were housed within concrete structures, a practice that contravened these established safety recommendations. This oversight became a significant point of contention for victims' families following the crash of Jeju Air Flight 2216 on December 29, 2024.
Localisers Housed in Non-Frangible Materials

The primary safety guideline disregarded at Muan Airport pertained to the material composition of navigation structures. International aviation standards explicitly recommend the use of frangible materials for localisers. This is to ensure that in the event of an aircraft incident, the structure itself breaks apart upon impact, thereby minimising damage and potential harm to passengers and the aircraft. At Muan, this crucial recommendation was not followed, with localisers being encased in concrete.
Nationwide Inspection Revealed Similar Violations

Following the tragic crash, a comprehensive nationwide inspection was conducted across South Korean airports. This inspection uncovered that Muan Airport was not an isolated case regarding the improper housing of localisers. The audit identified six other airports where navigation structures were similarly built with concrete or steel.
Remediation Efforts Underway at Other Airports

The discovery of non-compliant localiser structures at multiple airports prompted action. Out of the six other identified airports, five have since undergone retrofitting to ensure their localisers are now housed in breakable materials, aligning with international safety standards. The remaining airport is scheduled for similar retrofitting work next year, indicating a broader effort to rectify these safety lapses across the country.
