An Air India flight was grounded shortly after landing in New Delhi after a fire broke out in its auxiliary power unit on Tuesday.
Passengers were disembarking flight AI315 from Hong Kong when the fire was detected, according to the airline.
"The incident occurred while passengers had begun disembarking and the APU was automatically shut down as per system design," an Air India spokesman said.
The APU is installed at the back of the aircraft and serves as a backup power source, usually used to start the main engines and operate critical onboard systems while the aircraft is on the ground.
Passengers exited the aircraft safely but the aircraft, which landed at 12.31pm local time, was damaged, the spokesman said.
According to Flightradar24, the aircraft was listed as an Airbus A321.
Tuesday's incident marks the third Air India scare in just a couple of days.
A flight from Kochi to Mumbai swerved off a wet runway after landing in Mumbai on Monday.

The flight was ultimately rescheduled for later in the evening.
The litany of incidents comes in the wake of the scrutiny faced by the airline after the deadly Air India crash in Ahmedabad where 260 passengers were killed.
A month after the crash, a preliminary investigation found the Boeing Dreamliner's fuel control switches flipped from "run" position to "cutoff" within seconds of take-off.
It revealed one of the pilots was heard on the cockpit voice recorder asking his colleague why he had cut the fuel off.

The initial findings caused tension after pilot associations accused investigators of indirectly blaming the pilots for the crash.
The Wall Street Journal published a report which identified that pilot error could have played a role in the incident, although Indian authorities labelled it speculative.
Air India revealed it found no issues with the fuel control switch mechanisms on board its Boeing 787 and 737 fleet following the crash.
India's Aircraft Accident Investigation Bureau is expected to give its final report within the year.
