jakarta,Jurnas.com – Teleskop James Webb (JWST) mengkonfirmasi bahwa sebuah lubang hitam supermasif diduga sedang melarikan diri dari galaksi asalnya dengan kecepatan ekstrem, mencapai sekitar 3,6 juta kilometer per jam. Jika terkonfirmasi penuh, ini akan menjadi kasus pertama lubang hitam supermasif “kabur” yang berhasil diidentifikasi secara meyakinkan.

The Boeing 737 MAX, grounded worldwide in March 2019 following two fatal crashes, has undergone extensive software updates and safety reviews, leading to its recertification by aviation authorities. As of January 10, 2026, the 737 MAX is operating commercially, tho scrutiny and ongoing oversight remain in place.
The Boeing 737 MAX Grounding
Table of Contents
The Boeing 737 MAX grounding began on March 13, 2019, after the crash of Ethiopian Airlines flight 302, which followed the crash of Lion Air Flight 610 in October 2018. Both crashes involved the Maneuvering Characteristics Augmentation System (MCAS), a software feature designed to automatically push the nose of the aircraft down if it detects a stall.
Investigations revealed that MCAS relied on a single angle of attack (AOA) sensor,and pilots were not adequately informed about the system or trained to respond to malfunctions. The crashes resulted in the deaths of 346 people.
Example: the Ethiopian Airlines crash on March 10, 2019, killed all 157 people on board and was the catalyst for the global grounding. The NTSB final report details the contributing factors.
Recertification and Software Updates
The federal Aviation Management (FAA) initiated a review of the 737 MAX’s flight control system and software. Boeing developed software updates to address the MCAS issues,including making it less powerful and relying on two AOA sensors instead of one. Pilots were also required to undergo enhanced training.
The FAA conducted extensive testing and simulations of the updated software.Other international aviation authorities, including the European Union Aviation Safety agency (EASA), also conducted their own independent reviews.
Detail: The software updates included changes to the MCAS, pilot training requirements, and wiring harness separation to prevent potential short circuits. Boeing’s website provides details on the updates.
Example: On November 18, 2020, the FAA issued an Airworthiness Directive lifting the grounding order, allowing the 737 MAX to return to service with the implemented software updates and pilot training. FAA Airworthiness Directive 2020-23-02 outlines the conditions for return to service.
Recent Issues and Ongoing Scrutiny (as of January 10, 2026)
While the 737 MAX returned to service, boeing faced renewed scrutiny in early 2024 following an incident on Alaska Airlines flight 1282 on January 5, 2024, where a door plug blew out mid-flight. This led to a temporary grounding of some 737 MAX 9 aircraft for inspections.
The National Transportation Safety Board (NTSB) is investigating the Alaska Airlines incident, focusing on the installation of the door plug and quality control procedures at Boeing and its supplier, Spirit AeroSystems. The FAA has also increased oversight of Boeing’s manufacturing processes.
Detail: The FAA announced in March 2024 a 95-day plan to increase oversight of Boeing’s production and manufacturing processes. FAA News Release details the plan.
Update (January 10, 2026): As of this date, the FAA has allowed Boeing to resume increased production of the 737 MAX, but continues to maintain heightened oversight. The NTSB examination into the Alaska Airlines incident is ongoing,with a final report expected in late 2025 or early 2026. Boeing is implementing changes to its quality control processes, and the FAA is conducting regular audits. There have been no further in-flight incidents related to door plug failures as the inspections were completed. NTSB Preliminary Report provides ongoing updates.
