‘Installed as low as possible to prevent breakage’… Clear violation of airport safety operation standards
Facilities law – takeoff and landing site standards are also violated
The Ministry of Land, Infrastructure and Transport said, ‘Outside the safety zone, this does not apply’… “Needs interpretation” in one day, take a step back

The localizer (azimuth facility), which was pointed out as the cause of the Jeju Air passenger plane disaster in Muan, Jeollanam-do, was confirmed to have violated ‘airport safety operation standards’. Although the illegality of localizers continues to be revealed, the government is unable to provide a clear answer to this issue.

● Muan Airport localizer, violation of 300m standard

According to the aviation industry on the 2nd, Article 109, Paragraph 5 of the airport safety operation standards states that “facilities for navigation purposes in the area within 240m from the end of the landing pad must be easy to break and must be installed as low as possible.” A localizer is one of the navigation safety facilities that provides directional information to aircraft and helps with safe operation. Muan Airport’s localizer is installed within the area specified by the relevant standards. The runway length of Muan Airport is 2800m. There is a 60m long landing pad at the end of the runway. Article 109, Paragraph 5 of the Airport Safety Operation Standard describes the area within 240m from the end of the landing strip. In other words, navigation facilities within a total distance of 300m from the end of the runway are “easy to break and should be built as low as possible.” The localizer at Muan Airport is located 264 meters from the end of the runway. According to this regulation, the Muan Airport localizer built on a concrete mound about 2 meters high is in violation of the regulation.

However, the Ministry of Land, Infrastructure and Transport is unable to provide a clear answer, including reversing its position on whether the localizer installed on the concrete mound was installed properly according to regulations. The Ministry of Land, Infrastructure and Transport explained in a press release on December 31 last year, “The localizer was built in accordance with regulations.” In the ‘Detailed Guidelines for Aviation Obstacle Management under the Airport Facilities Act’, ‘Airport Safety Operation Standards Article 42’, and ‘Airport, Airfield Facilities and Takeoff and Landing Ground Installation Standards’, there are regulations such as “Localizers must be mounted on fragile pedestals.” there is. However, the government explained that these regulations apply only when there is a localizer within the terminal safety zone. Since the Muan Airport localizer is located 5m outside the longitudinal safety zone, this means that the relevant regulations are not applied.

● The Ministry of Land, Infrastructure and Transport gives mixed explanations.

However, the Ministry of Land, Infrastructure and Transport changed its position within a day. As detailed guidelines were released stating that ‘the area where the localizer is installed must also be designated as a longitudinal safety zone,’ they took a step back, saying, “Interpretation is necessary according to the regulations.” The Ministry of Land, Infrastructure and Transport’s notice, ‘Standards for Installation of Airports, Airfield Facilities and Landing and Takeoff Areas’, states that “the longitudinal safety zone must be extended to the point where the localizer is installed.” Here, it is necessary to discuss whether the expression ‘up to’ means including the localizer or ‘up to’ the localizer.

The Ministry of Land, Infrastructure and Transport also explained that concrete mounds similar to Muan Airport exist at Los Angeles (LA) Airport in the United States and Tenerife Airport in Spain. However, when questions continued to be asked as to whether the information was properly understood, the Ministry of Land, Infrastructure and Transport reserved its position, saying, “I will supplement it and tell you again.”

There is criticism in the aviation industry that the government is repeatedly giving back and forth explanations without verifying the facts about existing aviation regulations. Some point out that this opportunity should be used to significantly revise airport facilities and safety-related regulations. An official from an airport construction company said, “Domestic aviation-related regulations are largely based on interpretations of U.S. and Japanese laws, but in this process, many of the text is unclear,” adding, “Guidelines related to airport and facility installation are also here and there. “We need to take this opportunity to reorganize aviation-related laws,” he said.

The accident engine revealed Workers are pulling out the engine of the plane that was buried in a concrete mound at the site of the Jeju Air plane disaster at Muan International Airport in Jeollanam-do on the 2nd. One of the main causes of this accident is engine failure due to bird strike. Muan = Newsis

Meanwhile, the Jeju Air Passenger Plane Accident Investigation Headquarters of the Jeonnam Police Agency sent investigators to three locations, including the Jeju Air Seoul office, the Muan International Airport department office, and the Busan Regional Aviation Administration Muan Branch, from 9 a.m. on the 2nd to conduct search and seizure on charges of professional negligence causing death. proceeded. Investigators are said to have secured closed-circuit (CC) TV footage of the runway at Muan Airport, the content of communications exchanged between the control tower and the pilot just before the accident, and data on the maintenance history of the accident aircraft.
