Indonesia crash investigator says autothrottle problems on Sriwijaya Air plane Reuters 2/10/2021
JAKARTA, Feb 10 (Reuters) - The flight data recorder from the Sriwijaya Air plane that crashed last month killing 62 people showed problems with the autothrottle system that controls engine power automatically, Indonesia s air accident investigator said on Wednesday.
When the plane reached 8,150 feet (2,484 m) after take-off, the left throttle lever moved back while the right lever stayed in its original position, National Transportation Safety Committee (KNKT) investigator Nurcayho Utomo said.
The plane eventually rolled and then entered a dive into the Java Sea, he said. What we know is the left autothrottle moved backward, Utomo told reporters. We don t know if it s broken or not, but it s an anomaly because the left moved far back, the right did not as though it was stuck.

JAKARTA, Feb 2 (Reuters) - Indonesia s air accident investigator has sent five components of a crashed Sriwijaya Air jet to the United States and Britain for examination, including the autothrottle that controls engine power automatically, the agency s head said on Tuesday.
The 26-year-old Boeing Co 737-500 crashed into the Java Sea shortly after takeoff from Jakarta on Jan. 9, killing all 62 people on board.
National Transportation Safety Committee (KNKT) Chief Soerjanto Tjahjono told Reuters the components had been sent for examination to help find out why an autothrottle parameter had changed. He did not identify the other parts.
The plane s flight data recorder (FDR) has been found and read by investigators but a maritime search is going on for the cockpit voice recorder s (CVR) memory unit that Tjahjono said would help explain any human factors behind the crash.
