A Malaysian Airlines flight from Chennai was delayed for more than two hours after its pilot refused to take off over insufficient oxygen in the aircraft’s supply tank, leading officials to offload 78 passengers before the aircraft departed with 100 travellers.
The flight was scheduled to leave Chennai Airport at 11.55 pm on Sunday. According to a report by Deccan Chronicle, the pilot detected that the oxygen tank did not contain enough gas to circulate sufficient oxygen inside the aircraft for the passengers and crew on board.
The pilot informed the airport control room and senior officials that operating the flight in those conditions could pose a danger to passengers. The report said the aircraft had 178 booked passengers. It also referred to a total onboard count of 190, including staff, while describing the decision taken by officials to reduce the passenger count to 100.
A meeting involving senior officials, engineers and technical experts was subsequently held at the airport. They decided that the first 100 passengers in the booking order would be allowed to travel because Chennai Airport did not have a facility to refill the aircraft’s oxygen supply before departure.
The remaining 78 passengers were offloaded and argued with airport officials after being told that they could not board the flight. Officials pacified the passengers and informed them that arrangements would be made to transport them on alternative flights.
The Malaysian Airlines aircraft eventually departed at 2.20 am on Monday, more than two hours after its scheduled departure time. The passengers who were left behind were provided accommodation and other facilities at the airport, according to the report.
The incident places the focus on the operational safeguards that govern aircraft departure from a major international airport. The pilot’s decision, followed by a technical assessment involving airport officials and engineers, prevented the flight from operating with an oxygen supply that was considered inadequate for the intended passenger load.
The report did not identify the aircraft type, the exact oxygen quantity available in the tank, the destination of the flight or the specific alternative flights arranged for the offloaded passengers. It also did not state when the aircraft’s oxygen system would be replenished or whether the aircraft would undergo further technical checks after landing.
For passengers, the immediate impact was a delayed departure, offloading, accommodation arrangements and the need to travel on alternative services. For airport operations, the episode required coordination between the flight crew, the control room, engineers, technical experts and passenger-handling officials before the aircraft was cleared to depart with a reduced passenger count.
