The Air India Flight AI 315, operating from Hong Kong to Delhi on 22 July 2025, experienced an auxiliary power unit (APU) fire shortly after it had landed and parked at the gate. The incident, according to the airline, occurred as passengers were disembarking when the auxiliary power unit (APU) automatically shut down as designed.
Flight AI 315 sustained some damage and has been grounded for investigations. All passengers and crew members of Hong Kong to Delhi flight later disembarked safely.
“The aircraft has been grounded for further investigations and the regulator has been duly notified,” the airline said in a statement.
Last month, Air India flight AI 171 crashed soon after takeoff from Ahmedabad on June 12, killing 241 of the 242 passengers onboard and another 19 on the ground.
In its preliminary report on the Boeing 787-8 crash, Aircraft Accident Investigation Bureau (AAIB) said the fuel supply to both engines of the plane was cut off within a gap of one second, causing confusion in the cockpit soon after takeoff.Air India, however, said it has completed “precautionary” inspection of the locking mechanism of the fuel control switch (FCS) on its Boeing 787 and 737 aircraft fleet and no issues were found.Boeing 787s are part of Air India’s fleet, while B737s are operated by its low-cost subsidiary Air India Express.
Incidentally, the airline has reportedly been issued nine show cause notices in connection with five identified safety violations in the last six months. As per the civil aviation ministry statement in the Rajya Sabha on Monday, enforcement action has been completed with respect to one violation.
In a separate written reply, Minister of State for Civil Aviation Murlidhar Mohol said that during the last six months, no adverse trend was reported in reliability reports of Air India in respect of crashed aircraft.
