Failure to fix throttle led to Indonesia plane crash that killed 62: Report

Report on the #Sriwijaya Air crash, which killed 62 lives.

Airbus has confirmed that it will work with France, Germany, and Spain to build the Future Combat Air System (FCAS).

Investigators in Indonesia’s aviation industry came to the conclusion on Thursday that a Boeing 737-500 tragedy last year that killed 62 lives, a nearly decade-long to properly repair a malfunctioning automatic throttle, pilots’ overreliance on the plane’s automation system, and inadequate training contributed to the crash.

The automatic throttle issue with the Sriwijaya Air jet, which had been reported by pilots 65 times since 2013 and had not yet been resolved when the 26-year-old aircraft crashed into the Java Sea after taking off from Jakarta on January 9, 2021, according to the final report by the National Transportation Safety Committee’s investigators.

As it got closer to the target altitude, the plane needed less engine push, but mechanical friction prevented the automatic throttle from turning down the power of the right engine.

The left engine’s power was further reduced, down to 34%, using the automatic throttle in an attempt to make up for the loss. The power of the right engine stayed at its climb level, or around 92%, resulting in drastically unequal thrust, based on the report. The airplane tumbled onto its left side as the pilot struggled to get it up in the air but was unable to recover from the position.

After a minute, the flight recorder revealed that the automated throttle had been deactivated as the aircraft descended. A little while later, the recorder stopped recording.

Pilots can utilize the automated throttle to set the speed automatically, lessening their strain and engine wear in the process. 13 other plane parts are connected to the automatic throttle’s movements.

Numerous issues that contributed to the tragedy were exposed in a preliminary assessment released by Indonesian officials last year. New information on how the pilots responded to them was included in the final report that was issued on Thursday.

Boeing Transfers Rocket Stage to NASA, Paving Way for Human Moon Mission

Boeing has achieved a significant milestone by providing NASA with the second core stage of the Space Launch System (SLS) rocket.

This crucial component, crafted at NASA’s Michoud Assembly Facility (MAF), is set to propel the Artemis II crew into lunar orbit, marking humanity’s return to deep space after a 50-year hiatus.

The monumental Boeing-built rocket stage, the largest element of the Artemis II mission, will embark on a journey aboard the Pegasus barge, traveling 900 miles to NASA’s Kennedy Space Center.

Upon arrival, it will be meticulously integrated with other essential Artemis II components, including the upper stage, solid rocket boosters, and NASA’s Orion spacecraft within the iconic Vehicle Assembly Building. This intricate integration process is a vital step toward the eagerly anticipated Artemis II launch, slated for 2025.

“Boeing-built products helped land humankind on the moon in 1969, and we’re proud to continue that legacy through the Artemis generation,” remarked Dave Dutcher, vice president and program manager for Boeing’s SLS program. “Together, with NASA and our industry partners and suppliers, we are building the world’s most capable rocket and paving the way to deep space through America’s rocket factory in New Orleans.”

The delivery of Core Stage 2 marks a significant achievement in the evolution of the SLS rocket. Towering over 200 feet and powered by four RS-25 engines, this core stage, coupled with two solid-fueled booster rockets, will generate a staggering 8.8 million pounds of thrust. This immense power is crucial to launching Artemis II and future missions into the vast expanse of space.

The SLS rocket stands unparalleled in its capability to transport both crew and substantial cargo to the moon and beyond in a single launch. Its extraordinary capacity will facilitate the delivery of human-rated spacecraft, habitats, and scientific missions to destinations including the moon and Mars, ushering in a new era of space exploration.
