An Indonesia AirAsia Airbus A320 disappeared from radar over the Java Sea whilst operating flight QZ8501 from Surabaya on the eastern end of Java to Singapore on Sunday morning. As of Monday morning, 24 hours after contact was lost with the aircraft, no announcement had been made of any trace of the aircraft.

The flight departed Surabaya at 05.27 local time, and was operated by an Airbus A320 (PK-AXC) for the Indonesian subsidiary of the pan-Asian low cost carrier. Contact was lost at 07.24 Singapore time (10.20 AEDST), with search and rescue services in Singapore and Indonesia activated shortly afterwards. The aircraft was due to arrive in Singapore at 08.37 local time, but Jakarta air traffic control reported it missing at 07.54 in the area between Pulau Belitung and southern Kalimantan.

There were several severe storms on the aircraft’s planned route, and initial reports from AirNav Indonesia say the pilot had requested routing left of track and an ascent to 38,000 feet to avoid weather. The last ADS-B ping on flight tracking app Flightradar24 showed the aircraft travelling at 32,000 feet and 469kts. A China Airlines flight that followed a similar track about 45 minutes behind the missing flight also requested a re-routing left of track to avoid the weather.

An early statement on the airline’s Facebook page read in part: “At the present time we unfortunately have no further information regarding the status of the passengers and crew members on board, but we will keep all parties informed as more information becomes available. At this time, search and rescue operations are in progress and AirAsia is cooperating fully and assisting the rescue service.”


A passenger manifest released by Indonesian authorities indicate there were 155 passengers on board comprising 70 male adults, 68 female adults, 16 children and one infant, the majority of whom were Indonesian. The airline confirmed these numbers in a follow up Facebook post, and said there were also seven crew members on board comprising two pilots, four flight attendants and one engineer. All of AirAsia A320s are configured with 180 seats in a single class.

The aircraft in question entered service with AirAsia in 2008 and is powered by CFM56-5B3/6 engines, and the airline says it last underwent scheduled maintenance on November 16. “At this time, search and rescue operations are being conducted under the guidance of The Indonesia of Civil Aviation Authority (CAA). AirAsia Indonesia is cooperating fully and assisting the investigation in every possible way,” an airline Facebook entry posted at 16.23AEDST  reads. “The aircraft was on the submitted flight plan route and was requesting deviation due to enroute weather before communication with the aircraft was lost while it was still under the control of the Indonesian Air Traffic Control (ATC).”

Some media reports have drawn initial comparisons between the A320’s disappearance and that of the 2009 Air France 447 crash of an A330 in the Atlantic by suggesting while the A320 was climbing through 36,000 feet it had slowed to a less than optimal speed, but these are yet to be formally verified.

An Indonesia 737-200MPA was despatched to the search area on Sunday, and the Singapore Ministry of Defence earlier confirmed it had two C-130s on standby to assist.

A subsequent statement released at 16.00 Sunday local (19.00 AEDST) by the Civil Aviation Authority of Singapore (CAAS) said Indonesia had accepted the island state’s offer of assistance in the search and rescue effort. “The Singapore Rescue Coordination Centre (RCC), managed by CAAS and supported by various agencies, including the Republic of Singapore Air Force (RSAF) and the Republic of Singapore Navy (RSN), had offered assistance to BASARNAS, the Indonesian Search and Rescue Agency, at 0930 hours local time, this morning,” the statement read. “We have offered our planes and ships to assist in the search, and received confirmation from the Indonesian authorities this afternoon at 14.30 hours to accept our offer, requesting for one C-130 for now. We have already launched it to assist with the search and locate efforts.”

On Sunday afternoon AirAsia Group CEO Tony Fernandes tweeted that he was “On my way to Surabaya where most of the passengers are from as with my Indonesian management”, adding that he would be “Providing information as we get it.” He also said that “My only thought are with the passengers and my crew. We put our hope in the SAR operation and thank the Indonesia, Singapore and Malaysian governments.”

Airbus also issued a statement on Sunday evening saying the missing aircraft was MSN 3648 and that it had accumulated about 23,000 flight hours in about 13,600 flights since it was delivered in October 2008. “In line with the ICAO Annex 13 international convention, Airbus will provide full assistance to the French safety investigation authority, BEA, and to the authorities in charge of the investigation,” the manufacturer’s statement read.

An initial search of the last reported location of the A320 was conducted on Sunday night but was called off due to continuing bad weather and darkness in the area. It was due to recommence on Monday morning, and preliminary forecasts have shown an improvement in the weather in the search area.

Two Singaporean naval vessels sailed for the search area late Sunday night, while Malaysia has said it will be sending three vessels. An Indonesian C-130 and a Super Puma helicopter are reported to be preparing to join the search on Monday morning.

Australian Prime Minister Tony Abbott reportedly telephoned Indonesian President Joko Widodo on Sunday afternoon and offered the use of an RAAF Lockheed AP-3C Orion maritime patrol aircraft in the search. To this end, an AP-3C departed Darwin on Monday morning headed for the search area.

“The RAAF AP-3C Orion aircraft has a well proven capability in search and rescue and carries maritime search radar coupled with infra-red and electro-optical sensors to support the visual observation capabilities provided by its highly trained crew members,” Chief of Defence Force ACM Mark Binskin said in a brief statement.

India is also reported to have offered to send a Boeing P-8I Neptune patrol aircraft and several ships.

    Twice this year have modern aircraft vanished from radar screens with no radio call, emergency squawk code or other sign of distress being received. While the circumstances are different, the fact that it has happened should have industry safety experts scratching their heads. Things simply cannot vanish off the face of the earth. Something needs to be done sooner rather than later to prevent aircraft from disappearing without a trace.
