The APU of an Emirates Boeing 777-300ER caught fire at Chennai International Airport

Emirates Flight EK547, scheduled for Dubai, experienced a delay at Chennai International Airport on September 24, 2024, due to smoke emanating from the tail section during refueling. With 280 passengers on board, emergency responders acted swiftly to address the situation. The airline later apologized for the incident. Investigations indicated that the smoke originated from the aircraft's auxiliary power unit (APU), which is typical in older aircraft like this 14-year-old Boeing 777-300. The flight eventually departed at 00:12 IST on September 25. In transportation safety, such incidents underline the importance of regular maintenance and monitoring of aging aircraft, especially auxiliary systems. The prompt response by emergency services is commendable and highlights the significance of preparedness in aviation operations. However, the incident raises questions about the maintenance protocols for older fleets, as they may be more susceptible to mechanical failures. Airlines must ensure proactive measures are in place to safeguard passenger safety while balancing operational efficiency.
