Pilots twice reported issues with automated engine controls on a Sriwijaya Air jet days prior to a malfunction involving the exact same program performed a key role in the plane’s fatal January crash in Indonesia, according to the country’s investigators.
The preliminary report about the accident, which killed all 62 people on board and is very likely to stoke new worries about Indonesia’s air-protection file, implies the cockpit crew did not recover the plane from a steep lender and unexpected dive four minutes just after takeoff. Investigators reported that the upset arrived just after the car-throttle program, which is designed to instantly modify gas movement and thrust, unsuccessful to work adequately.
That suggests the pilots both did not realize the challenge or unsuccessful to offer with it in time, authorities reported.
Thrust from the still left engine minimized as intended while the plane was climbing away from the Soekarno-Hatta Intercontinental Airport in Jakarta, but thrust from the other engine did not, the report reported. When the plane neared eleven,000 feet—with the engines continuing to work at noticeably unique electrical power settings—it went from a usual nose-up place to a dangerously unstable, nose-down one particular within just five seconds, it reported.
The jet’s flight-facts recorder—one of its so-called black boxes—stopped operating twenty seconds afterwards, suggesting that this was roughly when the plane hit the h2o.
