Jin Air Flight Encounters Cabin Smoke Before Take Off, 122 Evacuated on January 2

A Korean aviation incident unfolded on January 2 when a Jin Air plane experienced an unexpected technical emergency before take off. The incident prompted the rapid evacuation of 122 individuals aboard the aircraft, including both passengers and flight crew members, from Jeju International Airport. The situation was contained swiftly, with no injuries reported during the emergency response.

Smoke Detected During Boarding Process

The aircraft was preparing for departure toward Pohang at the scheduled time of 12:25 p.m. local time when crew members detected unidentified smoke emanating from inside the cabin during the passenger boarding phase. According to reports from Yonhap News Agency and Jin Air representatives, the situation required immediate action, prompting all occupants to be safely evacuated from the plane in an orderly manner. The airline confirmed that no fire occurred during the incident and that the fire department response was not necessary.

Root Cause Traced to Auxiliary Power Unit Malfunction

Subsequent investigation by aviation authorities determined that the smoke originated from an overheating issue within the auxiliary power unit located at the rear section of the aircraft. The auxiliary power unit, which provides independent power to the plane when engines are not running, had developed a defect that caused it to exceed normal operating temperatures. This technical failure was responsible for the smoke generation that triggered the emergency protocol.

Professional Response and Operational Implications

The incident demonstrates the effectiveness of Jin Air’s safety procedures and crew training. The swift detection of the problem and the coordinated evacuation of all passengers and crew exemplified modern aviation safety standards. Such incidents, while alarming, are typically addressed through maintenance protocols and technical upgrades to prevent future occurrences. The plane will undergo thorough inspection and repair before returning to service.
