Passengers and crew on Air India Flight AI 315 faced a tense moment on July 22, 2025, when a fire broke out in the auxiliary power unit (APU) just after landing at Indira Gandhi International Airport in Delhi. Thanks to quick action by the aircraft’s safety systems and airport emergency teams, everyone disembarked safely, and the fire was quickly put out.
What Happened on Air India Flight AI 315?

On the morning of July 22, Air India Flight AI 315, which had traveled from Hong Kong to Delhi, arrived at Indira Gandhi International Airport. As the plane parked at the gate and passengers began to leave, the auxiliary power unit—an important part that supplies electricity when the main engines are off—caught fire. The APU’s safety system immediately detected the problem and shut itself down. Emergency teams at the airport responded right away, following strict safety procedures.
All passengers and crew left the plane safely. There were no injuries, and no one needed medical help. The fire was contained to the APU, and the rest of the aircraft was not affected. Air India confirmed that the aircraft is now grounded for a full investigation and will not return to service until it is declared safe.
Immediate Response and Safety Protocols
The quick response to the fire on Air India Flight AI 315 highlights the importance of modern safety systems and well-trained crews. The APU’s automatic shutdown worked as designed, stopping the fire from spreading. Airport emergency teams arrived quickly and followed all safety rules. Delhi International Airport Limited (DIAL) confirmed that the fire was put out fast and that all safety steps were followed.
A spokesperson for Air India said, “The safety of our passengers and crew is always our top priority. We are grateful that everyone is safe and thank the airport teams for their quick action.” The Directorate General of Civil Aviation (DGCA), which is India’s top aviation regulator, was notified right away and is now leading the investigation.
Aircraft Status and Investigation
After the incident, the affected aircraft was taken out of service. Air India stated that there was some damage to the plane, but there is no ongoing risk to passengers or airport operations. The DGCA and the Air Accidents Investigation Bureau (AAIB) are both investigating what caused the fire. The results of their investigation will help decide if any new safety steps are needed.
According to analysis by VisaVerge.com, the DGCA has already increased its oversight of Air India’s fleet after several recent incidents. The agency is expected to release a preliminary report on the APU fire within a few weeks. Depending on what they find, there could be new rules or safety checks for Air India and possibly other airlines in India 🇮🇳.
Background: Recent Safety Concerns and Policy Changes
The fire on Air India Flight AI 315 comes at a time when Air India’s safety record is under close watch. In June 2025, a tragic crash involving an Air India Boeing Dreamliner in Ahmedabad led to the deaths of 260 people. Early findings from that crash suggested that a fuel supply cutoff caused both engines to shut down soon after takeoff.
In response, Air India completed precautionary inspections on the Fuel Control Switch (FCS) locking mechanisms for all Boeing 787 and Boeing 737 aircraft in its fleet earlier in July 2025. These checks were done following DGCA safety directives. No problems were found during these inspections, but the airline and regulators remain on high alert.
A spokesperson for the DGCA said, “We are committed to ensuring the highest safety standards. All recent incidents are being thoroughly investigated, and we will take further action if needed.”
How the Incident Affects Passengers and Flight Operations
For passengers, the most important news is that everyone on board Air India Flight AI 315 is safe. The fire was contained, and there was no need for emergency slides or special medical help. However, the aircraft involved is now grounded, which may cause minor delays or changes to Air India’s Hong Kong-Delhi route until a replacement plane is found or the current one is cleared for use.
Passengers traveling with Air India in the coming weeks should be aware that there may be extra safety checks and possible delays as the DGCA increases its oversight. Air India has set up a special helpline for affected passengers and is sharing updates on its website and through customer service channels.
Key Points for Passengers:
– No injuries reported on Air India Flight AI 315
– Normal disembarkation—no emergency slides used
– Aircraft grounded for investigation
– Possible minor delays on the Hong Kong-Delhi route
– Extra safety checks may cause delays on other flights
Regulatory Oversight and Industry Response
The DGCA is leading the investigation into the APU fire and has already taken steps to improve safety across Air India’s fleet. The agency’s actions include:
– Fleet-wide inspections of key safety systems
– Close monitoring of Air India’s maintenance and operations
– Ongoing investigations into both the APU fire and the June Dreamliner crash
Delhi International Airport Limited (DIAL) praised the quick response of its emergency teams and said that all safety steps were followed. The airport remains fully operational, and there is no risk to other flights.
Aviation safety experts say that while fires in the auxiliary power unit are rare, modern aircraft are built to handle such problems. The automatic shutdown of the APU and the safe, orderly disembarkation of passengers on Air India Flight AI 315 show that safety systems and training are working as they should.
Expert Opinions and Passenger Advocacy
Aviation experts agree that the incident was managed well. One industry analyst noted, “The fact that the fire was quickly detected, the APU shut down automatically, and everyone left the plane safely shows that the safety systems in place are effective.”
However, some passenger advocacy groups are calling for more transparency and frequent safety audits. They want airlines and regulators to share more information about safety checks and any problems found, so travelers can feel confident about flying.
What Is an Auxiliary Power Unit (APU)?
The auxiliary power unit is a small engine located in the tail of most large aircraft. Its main job is to provide electricity and air conditioning when the main engines are off, such as when the plane is parked at the gate. The APU also helps start the main engines before takeoff. While fires in the APU are rare, they can happen due to mechanical problems or fuel leaks. Modern planes have automatic systems that detect fires and shut down the APU to prevent the fire from spreading.
Recent Safety Record and Industry Context
The APU fire on Air India Flight AI 315 is the latest in a series of safety incidents for Air India. The June 2025 Dreamliner crash in Ahmedabad was a major tragedy and has led to increased scrutiny of Air India’s maintenance and safety procedures. The DGCA has responded by ordering more inspections and reviewing safety protocols across the airline’s fleet.
Aviation experts say that while these incidents are serious, the overall safety record of commercial aviation in India 🇮🇳 remains strong. Most flights operate without problems, and safety systems are designed to handle emergencies.
What Happens Next?
The DGCA and the Air Accidents Investigation Bureau are expected to release their initial findings on the APU fire soon. If they find any problems with the aircraft’s design, maintenance, or crew training, they may order new safety checks or changes across the industry. This could include:
– More frequent inspections of APUs and other key systems
– Extra training for flight crews and maintenance staff
– Upgrades to equipment or safety procedures
Air India has promised to cooperate fully with the investigation and to follow any new rules that are put in place. The airline is also keeping passengers informed through its website and customer service channels.
