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

South Korea is set to make waves in the aerospace industry with the establishment of a cutting-edge Maintenance, Repair, and Overhaul (MRO) hub for F-35 fighter jets and IAI (Israel Aerospace Industries) aircraft.

Central to this initiative is the specialization in converting Boeing 777-ERSF, colloquially known as the “Big Twin,” from passenger to freighter configurations. Under the terms of the agreement, IAI will spearhead the conversion of six B777-300ER and B777-200LR aircraft annually, commencing in 2024. This strategic move is in response to the anticipated surge in demand for wide-body freighter aircraft capable of long-haul flights.

Furthermore, South Korea’s forward-looking vision extends beyond aircraft conversion, with plans to establish a Lockheed Martin F-35 maintenance, repair, and overhaul depot at Cheongju Air Base by 2027. This strategic move not only enhances the operational readiness of South Korea’s air force but also positions the nation as a regional hub for F-35 maintenance expertise.

In preparation for this expansion, thirty Republic of Korea Air Force (ROKAF) engineers and technicians are slated to undergo intensive maintenance training in the United States in 2025, a testament to South Korea’s commitment to fostering local expertise and talent.

IAI’s visionary approach to certification and collaboration underscores the potential for transformative change. With plans for the 777-300ERSF certification process set to unfold in Israel, followed by the rigorous scrutiny of regulatory agencies such as the US Federal Aviation Administration (FAA), the stage is set for the ‘Big Twin’ to soar to new heights of success.

In partnership with esteemed entities like STK and Incheon International Airport Corporation, this collaboration promises to unleash a wave of benefits, amplifying the resilience and competitiveness of the Korean aviation sector while catalyzing job creation and economic prosperity.

Can Airline Seat Cushions Be Used As Life Jackets?

Can Airline Seat Cushions Be Used As Life Jackets?

In the event of an aircraft ditching into water, there’s a common question: Can aircraft seats serve as an alternative to life jackets for flotation? The answer lies in understanding their respective functions.

While seat cushions can provide some buoyancy in water, they are not intended nor certified to function as life jackets. Their primary purpose is to offer cushioning for passengers during flight. On the other hand, life jackets are meticulously engineered to keep individuals afloat in water, equipped with buoyancy materials, secure straps, and reflective elements for visibility. They offer numerous advantages over mere cushions.

While a seat cushion might offer temporary assistance in staying afloat, it’s not a dependable substitute for a proper life jacket during an emergency. It’s crucial to utilize approved safety equipment when near bodies of water. A life jacket, designed to keep a person buoyant for extended periods, offers the rigidity needed for prolonged flotation and allows for easy movement of the arms to navigate effectively.

What fabric is used in aircraft seats?


Seats are meticulously designed to fulfill multiple purposes, ensuring passenger comfort, safety, and protection from unforeseen circumstances like fires and accidents. A typical design incorporates an aluminum frame with blocks of polyurethane foam affixed to it. Additionally, a layer of fire-resistant fabric, such as Kevlar or Nomex, is often applied over this framework, topped with a layer of cloth or leather.

Leather seats, while luxurious, are more expensive compared to traditional cloth seats. The majority of fabrics used in seat upholstery contain at least 90% wool fiber, with the remainder typically consisting of polyamide (nylon). Wool stands out as the primary fiber chosen for commercial airline seating fabric due to its desirable properties and suitability for such applications.

What is the lightest economy seat?

In recent times, airlines have been downsizing seat dimensions to accommodate more passengers, resulting in reduced cushion length and leg space. This contrasts with earlier times when airlines offered more generously cushioned seats and ample amenities.

According to Recaro Seats Company, their SL3710 model represents the lightest economy class seat available, weighing in at a mere 8 kg (17.6 lb.), setting a new standard in aircraft seating.

For individuals weighing more than 350 pounds, fitting into a standard economy-class seat can be a challenge due to the narrower dimensions. Economy seats, also referred to as “coach,” “standard,” or “main cabin” seats, typically range from about 40 to 48 centimeters in width, further emphasizing the need for more accommodating seating options.
