New Delhi, May 13 - Aeroflot flight SU273, a Boeing 777-300ER registered as RA-73142, operating a scheduled service from Bangkok to Moscow-Sheremetyevo, on May 6, 2025, was forced to make an emergency landing at Delhi’s Indira Gandhi International Airport after the flight crew detected a brief odor of melted plastic in the cabin. The aircraft, carrying approximately 425 passengers and crew, was over four hours into its journey when the incident occurred, prompting the captain to divert the flight in accordance with standard safety protocols. The plane landed safely at around 3:50 PM local time, and no injuries were reported. The swift response of the crew and coordination with air traffic control ensured a controlled and secure landing, highlighting the aviation industry’s rigorous safety measures.

The odor, described by Aeroflot as fleeting and unaccompanied by visible smoke, triggered an immediate decision to prioritize passenger safety. Upon landing, a full emergency was declared at the airport, mobilizing ground services to assist with the situation. All passengers were safely evacuated from the aircraft, and local maintenance specialists initiated a thorough technical inspection to determine the cause of the odor. Preliminary reports suggest that such incidents can stem from various sources, including electrical malfunctions or overheating components, though no official cause has been confirmed for this event. The aircraft, a relatively new Boeing 777-300ER powered by GE90 engines, remained grounded pending the completion of the investigation.
The diversion caused significant disruption to the flight schedule, with the onward journey to Moscow delayed due to both the technical inspection and crew duty time limitations. Aeroflot promptly began coordinating with Indian immigration authorities to secure border clearance and arrange hotel accommodations for the stranded passengers. The airline’s representatives also provided meals and refreshments to ensure passenger comfort during the unexpected layover. While the continuation of flight SU273 was initially reported as canceled, efforts were underway to rebook passengers on alternative flights, though logistical challenges persisted due to the large number of travelers involved.
This incident underscores the aviation industry’s unwavering commitment to safety, where even minor anomalies prompt decisive action. The emergency landing in Delhi is not an isolated event; similar diversions due to cabin fumes have occurred globally, reflecting the challenges of maintaining complex aircraft systems. For instance, comparable incidents involving other airlines have been attributed to mechanical issues or external factors, emphasizing the need for robust safety protocols. Aeroflot’s response, including its transparent communication and focus on passenger welfare, demonstrates the airline’s adherence to international aviation standards. As investigations continue, the findings will likely contribute to ongoing efforts to enhance aircraft safety and prevent future occurrences, reinforcing the industry’s dedication to protecting passengers and crew.
