Series of failures caused Boeing 737 Max Lion Air crash – KNKT investigators report

A Lion Air 737 MAX stream collided with the Java Sea not long after take-off from Jakarta on Oct. 29, 2018, killing all 189 people on board. The 737 MAX was grounded overall after a second destructive accident in Ethiopia in March 2019.

The groups of casualties of the main accident will be informed before the report into the loss of Lion Air flight 610 is made open, Indonesian National Transportation Safety Commission (KNKT) press official Anggo Anurogo told correspondents on Monday.

A starter report into the Lion Air mishap discharged keep going November concentrated on carrier upkeep and preparing and the reaction of a Boeing against the anti-stall system to an as of late supplanted sensor however didn’t give a reason for the accident.

The last mishap report discharged Friday said Lion Air flight 610, from Indonesia’s capital Jakarta to the island of Sumatra, slammed on the grounds that the pilots were never advised how to rapidly react to glitches of the Boeing 737 Max 8 fly’s autopilot flight-control system.

Highlights from the Report :

Fault Reporting Manual (FRM) The Boeing Company provides Fault Reporting Manual (FRM) and the Interactive Fault Isolation Manual (IFIM) which together provides a structured method for the aircraft operator to report and correct faults in aircraft systems. The manuals are linked by a unique 8-digit fault code for each fault. The FRM is primarily for the flight crews and the cabin crews and contains three alphabetical lists of faults, with a fault code for each fault. While the IFIM is for the maintenance crews which gives a fault isolation procedure for each of the faults.

Boeing 737-8 (MAX) Fault Handling System The Boeing 737-8 (MAX) is equipped with the Maintenance Awareness System (MAS) that provides the information directly related to airworthiness and system information. The system includes the MAINT light (amber color) on the overhead panel, stored fault information which can be accessed from the Multi-Function Display (MFD) control on the pedestal.

The Angle of Attack failure According to the Boeing 737-8 (MAX) Illustrated Part Catalogue (IPC), the installed Angle of Attack sensor part number is 0861FL1. Refer to the Fault Reporting Manual (FRM) the fault related to the AOA categorized as Observed Fault with the fault codes

Log Error: Lion Air pilots who experienced problems on a previous flight failed to properly note it in the plane’s log, so maintenance crews couldn’t make necessary repairs. Pilots on the fatal flight failed to perform the correct emergency procedure for a nose-down pitch of the plane. The co-pilot failed to understand the situation and was preoccupied with running the wrong emergency checklist.

Less time for a response : Boeing also made incorrect assumptions about how quickly pilots could respond to a malfunction and didn’t inform pilots of the existence of MCAS until after the Lion Air crash, making it harder for Lion Air’s pilots to save the plane and its passengers

Pakistan’s Ambitious Plan to Acquire and Produce Chinese FC-31 Stealth Fighter

Pakistan’s Ambitious Plan to Acquire and Produce Chinese FC-31 Stealth Fighter

Pakistan is embarking on an ambitious endeavor to bolster its air defense capabilities with the acquisition and potential local production of the Chinese FC-31 stealth fighter jet.

Talks are reportedly underway between the Pakistan Air Force (PAF) and the Shenyang Aircraft Corporation, the developer of the FC-31, signaling a significant leap forward for Pakistan’s military aviation prowess.

The FC-31, a mid-sized, twin-engine fifth-generation fighter, promises advanced air combat capabilities, including stealth technology that surpasses anything currently in the PAF‘s fleet. With plans to retire the JF-17 production line by 2030, the FC-31 could emerge as the new flagship aircraft, offering unmatched performance and versatility.

Experts speculate that Pakistan’s interest in the FC-31 could also signal broader implications for the international market. As China develops both land and carrier versions of the FC-31, analysts foresee it becoming a cost-effective alternative to pricier options like the F-35, potentially challenging the dominance of the US aerospace industry and reshaping global strategic rivalries.

Adding complexity to the deal is China’s push for the WS-13 engine, previously rejected for the JF-17 but now under consideration for both the FC-31 and future JF-17 variants. Engine standardization could streamline logistical and maintenance processes for the PAF, further enhancing the appeal of the FC-31.

While negotiations continue, the success of the FC-31 acquisition and local production hinges on several factors, including the outcome of the WS-13 engine discussions. Pakistan’s pursuit of the FC-31 comes amidst its eagerness to replace its aging fleet, with previous attempts to upgrade its F-16s by the United States due to geopolitical pressures.

Amidst these developments, Pakistan previous interest in the Turkish-made Kaan fifth-generation fighter underscores its eagerness to replace its aging fleet. Despite previous attempts to secure upgrades for its F-16s from the United States, Pakistan’s quest for advanced aerial capabilities has led it to explore alternative avenues, with the FC-31 emerging as a promising contender in its pursuit of air superiority.
