On January 6, 2024, the South Korean Ministry of Land, Infrastructure and Transport announced the transportation of flight data recorders from the Jeju Air flight 7C2216 crash to the United States for analysis. The Black Boxes from the tragically involved Boeing 737-800 were deemed too damaged for reliable data extraction within South Korea, necessitating their transfer to the National Transportation Safety Board (NTSB) based in Washington.
The tragic accident occurred during landing at Musan International Airport, where the aircraft reportedly veered off the runway and collided with the airport wall, resulting in the death of 179 out of 181 passengers on board.
The flight data recorder contains sensitive information such as flight altitude, speed, engine thrust, and deployment of landing gear, all useful for piecing together the sequence of events leading to the disaster. Given the significance attached to this analysis by both the South Korean authorities and aviation experts alike, investigators stress the importance of fully dissecting the data to understand the reasons behind this catastrophe.
The flight, which originated from Thailand, was reportedly encountered with bird strikes upon landing. Such strikes led to the malfunction of one of the engines but the crew failed to adequately execute emergency protocols or maintain effective communication with Musan Tower. Eventually, without landing gear, brakes, or flaps, the plane attempted to execute go-around procedures.
During the recovery attempt, the plane made a 180-degree turn, lining itself up for belly landing at the midsection of the runway. Unfortunately, the aircraft was unable to stop and crashed through the runway limits, resulting tragically.
Experts explain the high stakes of bird strikes; it depends largely on the size and quantity of birds. Smaller birds like sparrows usually have limited impact, whereas larger birds can lead to engine failure. For example, US Airways Flight 1549 successfully managed to ditch on the Hudson River after losing engine power due to a collision with six Canada geese.
Central to the concern surrounding the Jeju Air incident is the failure of the landing gear to deploy. Engine failure typically leads to diminished function of hydraulic systems, which are responsible for landing gear deployment. Normally, operational parameters would allow for mechanical and backup systems to support landing gear release, even with engine troubles. The Boeing 737-800 is equipped with three hydraulic systems, facilitating redundancy.
Despite this, the crew did not utilize emergency procedures, leading to the aircraft’s belly landing. Considering runway length, Musan's runway is 9,184 feet, sufficient for the Boeing 737-800 but not when critically malfunctioning. Without flight specifications deployed (landing gear), the aircraft needed over 11,100 feet to stop safely, highlighting the pressures the crew faced.
Notably, Gwangju Airport, approximately 21 nautical miles away and with slightly longer runways, could have served as an alternative landing site. Some experts are calling for changes and enhancements to landing procedures. Recognizing the distance and approach protocol should always guide whether to approach alternative airfields during emergencies, even when faced with complex decisions amid engine failure.
The tragic accident raises pivotal questions about crew training and decision-making during emergencies. With strict adherence to protocols, aircraft crews must tackle the uncertainty rapidly, ensuring they are well-prepared on every possible eventuality. Analyzing what led crew members to decide on their sequence of actions during this emergency ensures newer protocols can be fine-tuned successfully.
Today, the focus turns to the investigative authorities tasked with unraveling the technical intricacies of this incident. Trained investigators will analyze black box data thoroughly to preserve existing aviation safety standards and prevent future disasters. Each recommendation from such incidents is intended to fortify the already established safety net within civil aviation, providing constant vigilance against the possibilities of mishaps and errors.
Meanwhile, aviation experts caution about the compounding risk factors involving safety complacency and unpredictable factors, such as wildlife interactions with airports. Recent high-profile accidents have reminded both officials and the flying public of the inherent risks of air travel.
Looking toward the future, the necessary review of pilot training protocols based on findings from investigations of incidents like Jeju Air flight 7C2216 becomes evident. Making continuous assessments of aviation safety processes ensures all future flights come under rigorous scrutiny. Through learning from these experiences, the aim is to instill added resilience within flight operations, so tragedies such as this do not recur.
Engaging with the complexity of aviation safety processes, the Jeju Air flight incident spotlights the indispensable need for rigorous exploration and readiness at various levels of operational management.
The persistence of strong training frameworks and adherence to structured emergency protocols remains the objective of the global aviation community striving continuously for the utmost safety.
