A Jin Air flight from Takamatsu to Incheon was delayed for more than six hours due to equipment malfunctions [1].
The incident highlights the vulnerabilities of aircraft ground operations, where a failure in external power systems can trigger a cascade of safety warnings that prevent takeoff.
The flight was scheduled to depart on Monday, July 27, at 5:15 p.m. [1]. However, the aircraft experienced a fault in its external power-supply equipment, which began causing significant delays around 7 p.m. [1].
According to the airline, the situation worsened after passengers re-boarded the plane. A cabin-pressure system warning light illuminated, further delaying the departure [1, 2]. The total delay lasted approximately six hours and 20 minutes [1].
About 180 passengers were affected by the disruption [1]. The prolonged wait on the tarmac created uncomfortable conditions for those on board as they waited for the technical issues to be resolved.
Jin Air said the delays were the result of the external power equipment fault and the subsequent pressure system alert [1, 2]. The airline worked to address the technical failures before finally clearing the aircraft for travel to South Korea [1].

This incident underscores the critical role of Ground Power Units (GPUs) and the sensitivity of cabin-pressure monitoring systems. When external power fails or fluctuates, it can trigger secondary system warnings that require rigorous safety checks before a pilot is permitted to fly, resulting in significant operational delays for budget carriers.
