SYDNEY/JAKARTA: Indonesia’s chequered air safety record is again in the spotlight after a Sriwijaya Air jet carrying 62 people crashed into the Java Sea minutes after takeoff on Saturday, marking the country’s third major airline crash in just over six years.
Before the crash there had been 697 fatalities in Indonesia over the last decade including military and private planes, making it the deadliest aviation market in the world – ahead of Russia, Iran and Pakistan – according to Aviation Safety Network’s database.
The Sriwijaya crash of a Boeing Co 737-500 follows the loss of a Lion Air 737 MAX in October 2018 that contributed to a global grounding of the model and the crash of an AirAsia Indonesia Airbus SE A320 in December 2014.
Indonesia, an archipelago of thousands of islands, is highly dependent on air travel.
From 2007 to 2018, the European Union banned Indonesian airlines following a series of crashes and reports of deteriorating oversight and maintenance. The United States lowered its Indonesia safety evaluation to Category 2, meaning its regulatory system was inadequate, between 2007 and 2016.
Indonesia’s air safety record has improved in recent years, receiving a favourable evaluation by the United Nations aviation agency in 2018. But in a country with a large death toll from vehicle and ferry accidents, the safety culture is battling against a mindset that it is inevitable for some crashes to occur, experts said.
Saturday’s “crash has nothing to do with the MAX, but Boeing would do well to guide Indonesia – which has a chequered air safety record – to restore confidence in its aviation industry,” said Shukor Yusof, the head of Malaysia-based aviation consultancy Endau Analytics.
As authorities searched for the Sriwijaya jet’s flight data recorder and cockpit voice recorder, experts said it was too early to determine the factors responsible for the crash of the nearly 27-year-old plane.
The flight took off from Jakarta’s Soekarno-Hatta International Airport, the same airport from which the Lion Air jet took off and soon crashed into the sea. The Sriwijaya jet climbed to 10,900 feet within four minutes but then began a steep descent and stopped transmitting data 21 seconds later, according to tracking website FlightRadar24.
“There has been a lot of noise made about the speed of its final descent,” said Geoff Dell, an air accident investigation expert based in Australia. “It is indicative of what happened but why it happened is still in many ways a guess really. There are multiple ways you can get an aeroplane to go down at that pace.”
He said investigators would look into factors including mechanical failure, pilot actions, maintenance records, weather conditions and whether there was any unlawful interference with the plane. Most air accidents are caused by a combination of factors that can take months to establish.
VARIOUS FACTORS UNDER SCRUTINY
Sriwijaya’s operating record will also be placed under scrutiny.
“Its safety record has been mixed,” said Greg Waldron, Asia managing editor at industry publication FlightGlobal. He said the airline had written off three 737s between 2008 and 2012 due to bad landings that resulted in runway overruns, with the 2008 accident resulting in one death and 14 injuries.
The airline in late 2019 ended a year-long partnership with national carrier Garuda Indonesia and had been operating independently.
Just before ending the pact, more than half of Sriwijaya’s fleet had been grounded by the Transportation Ministry due to airworthiness concerns, according to media reports at the time.
Sriwijaya did not respond immediately to a request for comment, though the airline’s chief executive said on Saturday the plane that crashed was in good condition.
Like other Indonesian carriers, Sriwijaya had slashed its flight schedule during the COVID-19 pandemic, which experts said will be examined as part of the investigation.
“The challenges that the pandemic brings impacts aviation safety,” said Chappy Hakim, an Indonesian aviation analyst and former air force official. “For instance, pilots/technicians were downsized, salaries not paid in full, planes are grounded.”
