Sriwijaya plane crash
The Boeing 737-500 crashed into the Java Sea on January 9, killing all 62 onboard. Investigators are reviewing data from the flight data recorders, The autothrottle was producing more thrust in one of the engines than the other just before the crash. Indonesian investigators probing the January 9 crash of a Sriwijaya Air flight are looking at the possibility that a malfunctioning automatic throttle could have led to the pilots losing control, according to a person familiar with the investigation. The autothrottle was producing more thrust in one of the Boeing 737-500’s two engines than the other shortly before the plane carrying 62 people crashed into the Java Sea, said the person, who is not authorized to discuss the matter publicly. The device had been having problems on previous flights, the person said. Issues involving the autothrottle on the 737 have led to incidents in the past, and a similar malfunction on another aircraft model was a cause of a fatal crash in 1995 in Romania.
Nurcahyo Utomo, the lead investigator at Indonesia’s National Transportation Safety Committee, confirmed that a malfunctioning throttle was “one of the factors that we are looking at, but I can’t say at this point that it’s a factor for the crash or there was a problem with it”.
Utomo’s team is working with engineers from Boeing to review the data from the aircraft’s flight data recorder that was retrieved from the seabed last week. Rescuers are still trying to locate the memory module of the plane’s cockpit voice recorder, which broke apart upon impact. Unequal thrust from the engines can cause a plane to turn or even roll onto its side and descend abruptly, if it is not handled properly. Pilots must compensate by manually setting the power or taking other actions.
Search and rescue efforts were suspended overnight but were due to resume on Sunday. The Indonesian navy was reportedly deployed to look for the aircraft on Saturday. Navy official Abdul Rasyid told Reuters news agency it had determined the plane’s coordinates and ships had been deployed to the location. The aircraft is not a 737 Max, the Boeing model that was grounded from March 2019 until last December following two deadly crashes.
According to registration details, the plane is a 26-year-old Boeing 737-500. It was in good condition, Sriwijaya Air chief executive Jefferson Irwin Jauwena told reporters. Take-off had been delayed for 30 minutes due to heavy rain, he said. Sriwijaya Air, founded in 2003, is a local budget airline which flies to Indonesian and other South-East Asian destinations.

The plane went missing about 20km (12 miles) north of the capital Jakarta, not far from where another flight crashed in October 2018. A total of 189 died when an Indonesian Lion Air flight plunged into the sea about 12 minutes after take-off from the city.
