532:(DGCA) released their final report, concluding that the probable cause of the incident was the complete dislodging of the No.1 strut fuel feed line coupling, which was caused by the dislodging of the tie wire from the failed tie wire hole. This dislodging then resulted in a heavy fuel leak. Even though the pilots had switched off their engines, the leaked fuel fell onto the hot engine No.1 setting a fire. The pilots' failure to detect the fuel leak during the walk-around inspection, as well as the lack of situational awareness and crew coordination, were some significant factors that contributed to the incident. According to investigators, the issues with AI829 actually began much earlier than the incident itself. Flight 829 was scheduled to depart at 02:00, but was delayed by 2 hours and 30 minutes due to technical problems. The original aircraft assigned to the flight began to taxi for take-off but had to abort shortly after due to the same issues, as a false fire alarm had gone off in the cockpit. Upon inspection, engineers discovered water in the cargo compartment that triggered the alarm. The flight was eventually delayed until 10:45, and another Boeing 747, VT-ESM (the aircraft involved), was assigned to operate the flight. Following the incident, the DGCA instructed Air India to assess its maintenance programs and practices and to conduct frequent and effective inspections to identify any potential fuel leaks in its aircraft.
508:(CCIC) saw the person signaling, she was unable to determine the reason and therefore disregarded it. A follow-me jeep somewhere in the area also noticed the fuel leaking from the aircraft and it instantaneously informed the ATC about the situation. The follow-me jeep was only able to provide the registration number of the aircraft to the ATC. As the aircraft turned onto taxiway A3, the ATC called out for VT-ESM twice but received no response from the aircraft. Finally, the ATC called out AI829 to verify the registration as ESM, which was confirmed by the crew. Once the registration was confirmed, the ATC informed the flight crew about the major fuel leak and ordered them to immediately switch off their engines. The captain halted the aircraft and began the

At the same time, the passengers became aware of the fire outside the cabin windows and immediately began rushing towards the exit doors. As the passengers evacuated using the escape slides, 21 of them sustained minor injuries. Once it was confirmed that no one was left onboard, the CCIC evacuated the aircraft. Interestingly, both pilots evacuated directly from the cockpit and didn't come down to the lower deck during the evacuation. In fact, they left the aircraft before the evacuation was complete. The left wing of the aircraft suffered fire damage to its leading and trailing edges, along with engine No.1 and

Taxiway G, an engineer assigned to another company's aircraft noticed the fuel leak coming from the No. 1 engine of the aircraft. Without hesitation, the engineer took off his ramp jacket and began signaling to the aircraft. Although the

The passengers were then deplaned, the delay was extended to 10:45, and VT-ESM, the aircraft involved in the incident, was assigned to perform the flight with a delay of more than eight hours. After all the passengers and crew reboarded the aircraft, at around 10:48 IST, since VT-ESM was without a serviceable

It was determined that the heavy fuel leak led to a fire that resulted from the complete dislodging of the coupling in the No.1 strut fuel feed line. The reason for this dislodging was the failure of the tie wire hole and the subsequent dislodging of the tie wire. As a result, the leaked fuel fell
