FAA issued 737 MAX’s LEAP-1B engine corrosion issue

FAA

FAA issued 737 MAX’s LEAP-1B engine corrosion issue: The FAA has released a new Airworthiness Directive for some CFM LEAP-1B engines used in the 737 MAX family of aircraft. The Directive addresses corrosion caused by long-term storage of planes, which can result in reduced thrust in certain cases. The remedy is simple enough, and it does not place a huge burden on the affected airlines.

When an aircraft is parked for an extended period of time without use, it is common for certain parts to begin to display signs of wear and tear. The global 737 MAX fleet was grounded for more than two years.

According to the FAA, there have been several reports of pressure sub-system (PSS) unit faults due to corrosion after storage for some CFM LEAP-1B engines. It explicitly states,

“In April 2021, the FAA received a report from CFM, the engine manufacturer, of numerous instances of PSS unit faults. The manufacturer reported these faults have been occurring since October 2020 and are a result of pressure transducer corrosion following extended storage periods. The manufacturer’s investigation found that certain PSS units, identified by serial number, have been exposed to conditions that make pressure transducers in these units susceptible to an increased rate of faults.”

The FAA has issued a new guideline requiring airlines to conduct repeated engine tests. The US authority stated that for Leap-1B engines that were restored to service but had less than 15 hours of electrical power applied to the PSS unit within the previous 90 days, the airline should monitor the engine maintenance messages related to the pressure transducer until the unit had 15 or more hours of electrical power.

Meanwhile, the FAA needed a one-time engine review for engines that had been returned to service and had already collected 15 or more hours of electrical power to the PSS units during the previous 90 days or completed 5 flight cycles.

The same law applies to air carriers that still have Leap-1B engine-powered aircraft in long-term storage. The FAA also cautioned that if any maintenance flaws were discovered during the tests, air carriers would have to replace the PSS units.

According to the FAA’s AD, it affected 158 engines registered in the United States. This fault has nothing to do with the electrical problem that was recorded in late April.

India is set to build a central command for the Air Traffic Control system, called ISHAN

India’s air traffic growth has led to increased responsibilities for air traffic control. The Airports Authority of India (AAI) is considering centralizing air traffic control for aircraft, dividing the country into four regions. The goal is to consolidate India’s segmented airspace into a single entity to improve air traffic management (ATM) efficiency, safety, and smoothness.

Recently, the AAI invited expressions of interest to develop a detailed project report for the Indian Single Sky Harmonized Air Traffic Management (ISHAN) initiative in Nagpur. Under this plan, air traffic controllers in Nagpur would handle domestic flights flying above 25,000 feet, eliminating the need for coordination among controllers in different regions.

For domestic regional flights operating above 25,000 feet, control would shift to the central command in Nagpur. This consolidation aims to enhance airline operations, increase flight handling capacity, and reduce congestion and flight times for passengers.

Currently, the AAI provides ATM services over Indian airspace and adjoining oceanic areas, covering over 2.8 million square nautical miles. This airspace is divided into four flight information regions (FIRs) in Delhi, Mumbai, Kolkata, and Chennai, along with a sub-FIR in Guwahati.

FIRs are responsible for providing air traffic services, including weather information, visibility, and search and rescue assistance. The proposed unification under the ISHAN initiative aligns with the projected growth of the aviation industry, which anticipates a doubling of domestic passenger traffic by 2030.

Airbus is set to increase the production rate for the A350 as demand surges

Airbus is set to increase the production rate for the A350 as demand surges

Airbus SE is set to boost production of its advanced A350 widebody jet as it capitalizes on rising demand for long-distance travel and wide-body aircraft, amidst the ongoing crisis affecting its competitor Boeing due to issues with the B737 Max.

The surge in orders for Airbus’s A350 aircraft has instilled confidence in the company, prompting them to ramp up production rates. This move is particularly advantageous as Boeing continues to grapple with production quality issues surrounding its 787 and 777x aircraft.

In 2024 alone, Airbus has received 137 orders for the A350, signaling a need to expand manufacturing capabilities to meet customer demands. With 1,277 orders received and 592 aircraft delivered as of April 2024, Airbus is poised to fulfill pending deliveries efficiently.

The European aircraft manufacturer announced plans to increase production of A350 jets to 12 per month by 2028, surpassing earlier projections aiming for 10 per month by 2026. This decision was disclosed alongside the company’s first-quarter figures.

The Asian market is proving lucrative for the A350, with significant orders from airlines like Indigo and Air India, totaling nearly 70 aircraft commitments for the future. Meanwhile, Airbus is progressing with its A220 and A320 programs, aiming for a monthly production rate of 14 and 75 aircraft, respectively, by 2026. Additionally, the long-range A321XLR is anticipated to commence service in the third quarter of the current year.

In contrast, Boeing has been compelled to scale back production due to regulatory pressures aimed at enhancing factory processes. While Airbus anticipates a positive market outlook, Boeing continues to face challenges with FAA certification and quality approvals, resulting in ongoing delays for its 737 Max and 777x models.

Financially, Boeing reported a significant cash burn of $3.9 billion in the first quarter, leaving it with $7.5 billion in cash and short-term securities by the quarter’s end, down from $16 billion at the beginning of the year. Consequently, Boeing’s stock has plummeted by 38% in the year so far, contrasting with Airbus’s 14% gain, marking Boeing’s lowest performance in over a year.

All passengers killed in plane crash, after pilot let his children to control the plane

All passengers killed in plane crash, after pilot let his children to control the plane

When boarding a plane, passengers entrust their safety to the skilled hands of the pilot. However, tragedy struck when one of the flight ended in disaster as all passengers lost their lives in a horrific plane crash.

In 1994, during a flight from Moscow to Hong Kong, tragedy struck as an Aeroflot relief pilot made a fateful decision. In a move that would have devastating consequences, the pilot invited his own children into the cockpit to play with the controls. Little did anyone know, this seemingly innocent gesture would lead to the loss of all 75 lives aboard the aircraft.

It was a seemingly innocent act that led to catastrophic results. The relief pilot, Mr. Kudrinsky, invited his two children, Yana, 12, and Eldar, 15, into the cockpit during the late hours of the night. Little did anyone know, this simple gesture would set off a chain of events that would end in tragedy.

Once in the cockpit, the children were allowed to sit in the captain’s chair and play with the controls, unaware that they should have been disabled as the plane was in autopilot mode.

Eldar, perhaps in a moment of curiosity or innocence, held the control column down for a mere 30 seconds. Yet, in those brief moments, the autopilot disengaged, thrusting the aircraft into manual control.

By the time the pilots regained their seats and attempted to regain control, it was too late. Despite their efforts to pull the plane out of a dive, they overcorrected, causing the flight to climb almost vertically, ultimately stalling it.

Final moment Flight 593 crash

In the final moments, as the pilots struggled to stabilize the aircraft, Flight 593 crashed into the Kuznetsk Alatau Mountain range in southern Russia, completely obliterating the plane and claiming the lives of everyone on board.

Investigations revealed a chilling truth: there was no evidence of technical failure. Instead, the crash was attributed to the unthinkable decision to allow inexperienced hands to manipulate the controls of a commercial aircraft.

The black box recording captured the harrowing sequence of events, providing a grim reminder of the human cost of a lapse in judgment. In just over two minutes, the lives of all on board were tragically short, leaving behind a legacy of sorrow and unanswered questions.
