The FAA proposes to supersede Airworthiness Directive (AD)
2018-23-51, which applies to all The Boeing Company Model 737-8 and 737-9 (737 MAX) airplanes. Since AD 2018-23-51 was issued, the agency has determined that final corrective action is necessary to address the unsafe condition.

  • require installing new flight control computer (FCC) software,
  • revising the existing Airplane Flight Manual (AFM) to incorporate new and revised flightcrew procedures,
  • installing new MAX display system (MDS) software,
  • changing the horizontal stabilizer trim wire routing installations,
  • completing an angle of attack sensor system test,
  • performing an operational readiness flight

Through a thorough, transparent, and inclusive process, the FAA has preliminarily determined that Boeing’s proposed changes to the 737 MAX design, flightcrew procedures and maintenance procedures effectively mitigate the airplane-related safety issues that contributed to the Flight 610 and Flight 302 accidents. The FAA further preliminarily determined that the proposed design change also address additional safety concerns beyond those identified during the accident investigations. This report does not address other safety issues that might have contributed to the accidents but are not related to airplane design. This includes the airline maintenance practices, the aircraft operators’ compliance posture, and pilot training effectiveness. The FAA believes recommendations related to these other potential contributing factors should be addressed by thappropriate organizations: Preliminary Summary of the FAA’s Review of the Boeing 737 MAX

Return to Service:
The FAA would revise the Emergency Order of Prohibition to allow the 737 MAX to return
to service based on completion of the following actions:
 Completion of all TAB return to service (RTS) recommendations and acceptance by
the TAB of those completed actions.
 Successful completion by Boeing — and acceptance by the FAA — of all regulatory
requirements, including aircraft design, documentation, training, and maintenance
aspects.
 Publication of two Notices to FAA inspectors containing national policy on minimum
required maintenance program changes and pilot training program changes that
relate to the 737 MAX design change. The Notices direct FAA maintenance and
operations inspectors to mandate the changes to U.S. air carrier maintenance
programs and pilot training programs in accordance with applicable U.S. operating
rules.
 Issuance of an AD that will provide specific instructions for steps the FAA deems
necessary that owners or operators must take to correct the unsafe condition, and
to support public confidence.

Additionally, the following conditions would be prerequisites to resuming operations in the
U.S.:

 For previously delivered 737 MAX airplanes, owner/operators must incorporate all
FAA-mandated design changes and maintenance actions.
 For any future delivered 737 MAX airplanes, Boeing is required to incorporate the
same mandatory actions.
 All 737 MAX operators must complete all pilot training identified in the revised 737
MAX FSB report.

HAL’s Indigenous Tejas MK-1A completes its first maiden flight

The LCA Tejas Aircraft Crash: Understanding the Reasons - Air Marshal GS Bedi's Perspective

The inaugural flight of the first production series fighter of LCA Tejas Mark-1A, an advanced iteration of the LCA Mk-1 recently inducted by the Indian Air Force (IAF), completed its maiden flight in Bengaluru Today.

Over the past several days, the Defence PSU HAL has been conducting various taxi trials in preparation for this milestone.

The maiden flight lasted 18 minutes and marked a triumph for the project. The Mk-1A boasts several enhancements, including digital radar warning receivers, an advanced AESA radar, improved beyond-visual-range (BVR) air-to-air missiles, and external self-protection jammer pods.

The upgraded Tejas Mark 1A aircraft features a larger cockpit canopy, enhancing the pilot’s outside visibility and facilitating better movement of their helmet. Additionally, the air intake has been redesigned to supply faster airflow to the engine, enhancing performance. Modifications to the vertical radar in the tail section have been made to improve control during turns. Overall, these upgrades elevate the aircraft’s standards compared to previous versions, providing increased comfort and functionality.

Under a contract worth Rs 46,898 crore signed in 2021, HAL is mandated to deliver 83 Tejas Mk-1A jets between March 2024 and February 2028. This follows the completion of the order for 40 Tejas Mk1 jets valued at Rs 8,802 crore, of which 32 single-seat fighters and two twin-seat trainers have already been delivered.

The IAF, which currently operates two Tejas squadrons named ‘Flying Daggers’ and ‘Flying Bullets’, has deployed one squadron in the southwestern sector. Recognizing the significance of the Tejas in bolstering its fleet, the Defence Acquisition Council (DAC) has approved the acquisition of an additional 97 Tejas Mk-1A aircraft. However, the final clearance from the cabinet committee on security (CCS) is pending before the order can be placed.

With the IAF grappling with a decline in the number of its fighter squadrons, which currently stands at 31 against the required 42 to effectively counter threats from China and Pakistan, the Tejas assumes a crucial role in filling this gap. Despite initial skepticism, the Tejas has evolved into a flagship platform for India, garnering attention and accolades at numerous defense and aerospace exhibitions worldwide.

However, it is essential to note that the IAF recently experienced its first loss of a Tejas Mk 1 fighter aircraft due to an air crash on March 12.

South Korean KF-21 Completed First Successful Aerial Refueling

South Korean KF-21 Completed First Successful Aerial Refueling

The first aerial refuelling test of South Korea’s indigenous KF-21 Boramae fighter jet was successfully completed, marking a key milestone in the country’s defense capabilities.

Refueling from a Republic of Korea (ROK) Air Force KC-330 aircraft off the southern coast, the Boramae fighter jet took off from Sacheon Airbase, some 183 miles southeast of Seoul. The Defence Acquisition Programme Administration (DAPA) hailed this development, which represents a significant advancement for this state-of-the-art aircraft.

The successful aerial refueling test corresponds with a staged production plan intended to ease worries brought forward by the feasibility assessment carried out a year ago. The research recommended cutting production to just 20 units and made additional test suggestions. A DAPA official continues to state that after discussions with pertinent agencies, plans are in place to conclude verification testing by June of this year and complete a contract for the remaining 20 units by February of the following year.

The kf 21, which has been compared to the Turkish KAAN and the Indian AMCA, has a more stealthy airframe than fourth-generation aircraft, but it is not yet capable of fifth-generation fighter capabilities. However, in the future, modifications such as internal weapons bays might force South Korea to reclassify it as a fifth-generation fighter. Even while South Korea has made significant strides towards constructing the KF-21, other countries, including Turkey and India, are also stepping up their efforts to push plans for creating fifth-generation fighter jets.

As an initial phase, KAI boramae intends to manufacture a two-seat variant of the kai kf 21 boramae equipped with manned/unmanned teaming (MUM-T) capabilities. According to current plans, the Block 2 kf 21 fighter is slated for an upgrade to a low observability (LO) configuration, elevating it to the status of a fifth-generation fighter.

Additionally, KAI has put forward a proposal for the development of a Block 3 kf 21 boramae fighter jet, categorized as a sixth-generation fighter. This iteration would be larger, boasting enhanced stealth features and capabilities. It would incorporate more potent engines and operate within a comprehensive ‘system of systems’ framework, integrating with unmanned effectors for increased effectiveness.

With the KF-21’s production set to start later in the year, DAPA intends to finalise an agreement with KAI by the beginning of 2024. The Republic of Korea Air Force (ROKAF) is expected to receive 120 KF-21 fighters by 2032.

The whole production plan for 40 kf21s has been approved by the Defence Project Promotion Committee, with an estimated cost of 7.92 trillion won (US$5.9 billion) between now and 2028.
