The Australian Transport Safety Bureau (ATSB) has called on AirAsia Indonesia to review its pre-flight briefing and safety information card after unfamiliarity with the oxygen masks caused passenger confusion on a recent flight.

The captain then informed the 146 passengers and four cabin crew of the emergency descent and deployed the oxygen masks.

“Consequently, several passengers moved around the cabin to secure a spare oxygen mask”.

The ATSB final report said one of the cabin crew members (P1) put on an oxygen mask and announced three times to the passengers “GRAB MASK, FASTEN SEATBELT, BREATHE NORMALLY” and used hand signals to demonstrate the instructions.

“During disembarkation she then received several passenger reports of the cabin crew members at the rear panicking, shouting and alarming the children,” the ATSB final report said.

“The ATSB recommends that AirAsia Indonesia take further action to review its current passenger pre-flight safety briefing and safety information card to ensure passengers are provided with clear instruction on how to activate the flow of oxygen from the passenger oxygen masks and that the bag may not inflate when oxygen is flowing”, the ATSB final report said.
