Jakarta (AFP) – Relatives of 62 people killed when an Indonesian passenger jet slammed into the sea scattered flowers at the crash site on Friday (Jan 22), as investigators look for clues to why the plane dropped from the sky minutes after take-off.
The memorial came as the search for human remains and wreckage ended two weeks after the Sriwijaya Air Boeing 737-500 plunged roughly 3,000m in less than a minute before crashing into waters off Jakarta.
However, the hunt continues for a still-missing cockpit voice recorder, as investigators pore over details from a retrieved flight data recorder – so-called black boxes that could be critical to the probe.
Maintenance logs pointed to an issue with the plane's auto-throttle, which controls engine power, the authorities said, but it was not clear what role – if any – the apparent malfunction played.
On Friday, dozens of relatives tossed red petals from the deck of a navy ship, some overcome with emotion.
"When I cast the flowers I could see my sister's face on the surface of the water," said Ms Heri Purnomo, whose older sibling Agus Minardi and her husband were on the flight. "I burst into tears... It was a very sad moment."
Mr Jefferson Irwin Jauwena, the airline's president director, said he was "devastated" by the accident which claimed 12 crew lives. "We also feel sad and lost," he said.
So far, 47 of the 62 victims have been identified through fingerprints and DNA matches to living family. But Ms Bety Saprianti, 33, who lost five relatives, is waiting for her aunt to be officially identified.
"We did not attend the ceremony today. None of our family joined – it was too painful," she said. "Our only hope now is (the last) of our relatives is identified soon."
The 26-year-old plane crashed just four minutes after setting off from Jakarta, bound for Pontianak city on Borneo island, a 90-minute flight away.
The authorities said the crew did not declare an emergency or report technical problems with the aircraft before its dive, and that it was probably intact when it hit the water – citing a relatively small area where the wreckage was scattered.
The crash probe is likely to take months, but a preliminary report is expected next month.
