Investigators: Throttle problem suspected in Indonesia crash
JAKARTA, Indonesia — A malfunctioning automatic throttle may have caused the pilots of a Sriwijaya Air jet to lose control, leading to the Boeing plane’s plunge into the Java Sea last month, Indonesian investigators said Wednesday.
National Transportation Safety Committee investigators said they are still struggling to understand why the jet nosedived into the water minutes after taking off from Jakarta on Jan. 9, killing all 62 people on board.
The investigators issued a preliminary report that provided new details of the pilots’ struggle to fly the plane from almost as soon as it became airborne.
The lead investigator, Nurcahyo Utomo, said the left engine’s throttle lever had moved backward on its own while autopilot was engaged, reducing the power output of that engine just before the jet plunged into the sea.
