This led in the crash of Yeti Airlines Flight 691, which killed 72 lives.

On 15 January 2023, an ATR 72-212A was operating scheduled flights between Kathmandu (VNKT) and Pokhara International Airport (VNPR). The
same flight crew operated two sectors between VNKT to VNPR and VNPR to VNKT earlier in the morning. The accident occurred during a visual approach
for runway 12 at VNPR. This was the third flight by the crew members on that day. The flight was operated by two Captains, one Captain was in the process
of obtaining aerodrome familarization for operating into Pokhara and the other Captain being the instructor pilot. The Captain being familarized, who was
occupying the left hand seat, was the Pilot Flying (PF) and the instructor pilot, occupying the right hand seat, was the Pilot Monitoring (PM).

The take-off, climb, cruise and descent to Pokhara was normal. During the first contact with Pokhara tower the Air Traffic Controller (ATC) assigned the runway
30 to land. But during the later phases of flight crew requested and received clearance from ATC to land on Runway 12.

After both engines’ propellers were feathered, the plane lost thrust and crashed. It is unusual for the propellers of both engines to become feathered, according to the report.

“When the Air Traffic Controller (ATC) provided the clearance for landing…, the Pilot Flying (PF) stated twice that there was no power coming from the engines,” according to the investigation.

The aircraft’s engines were fully operational at the time of the crash. Flaps are rectangular panels on the wings that are stretched to expand their surface area and provide greater lift to the aircraft during slow-speed landing and takeoff. The plane loses lift and crashes if the flaps are not extended before landing. During landing, bringing the engine to idle speed with no flaps extended is a very unstable arrangement.

When both propellers were feathered, the investigation team observed that both engines of 9N-ANC were running flight idle conditions during the event flight
to prevent over torque. As per the FDR data, all the recorded parameters related to engines did not show any anomaly. At 10:56:50 when the radio
altitude callout for five hundred feet3 was annunciated, another “click” sound was heard4. The aircraft reached a maximum bank angle of 30 degrees at this
altitude. The recorded Np and Tq data remained invalid. The yaw damper disconnected four seconds later. The PF consulted the PM on whether to
continue the left turn and the PM replied to continue the turn. Subsequently, the PF asked the PM whether to continue to descend and the PM responded
it was not necessary and instructed to apply a little power. At 10:56:54, another click was heard, followed by the flap’s surface movement to the 30 degrees position.

An A320 plane flew for 28 minutes with both pilots asleep

An A320 plane flew for 28 minutes with both pilots asleep

In a startling incident, an Airbus A320 operated by an Indonesian airline, Batik Air, flew for a harrowing 28 minutes with both pilots asleep at the controls.

The alarming event unfolded on Batik Air Flight 6723, carrying 153 passengers, en route to Soekarno–Hatta International Airport in Jakarta. The saga began when the first officer allowed the captain to take a nap, only to fatigue himself, attributing his drowsiness to caring for his one-month-old twins. As the pilots dozed off, the aircraft veered off-course, prompting concerns from air traffic control (ATC) who lost contact with the flight 90 minutes into its journey.

Despite the pilots being unresponsive for nearly half an hour, ATC managed to track the aircraft using radar as it covered a staggering 210 nautical miles, equivalent to the distance between New York and Washington, D.C. The captain eventually woke up, realizing the perilous situation and rousing his co-pilot.

After correcting the flight path, the captain attributed the radio silence to a “communication problem,” and the plane eventually touched down safely in Jakarta. However, the incident sparked widespread concern and investigation by Indonesia’s transport ministry.

A preliminary report revealed that the second-in-command had not rested adequately before the flight, shedding light on the potential dangers of pilot fatigue. While the identities of the pilots remained undisclosed, the incident underscored the critical importance of ensuring crew members are well-rested and fit for duty.

Despite the gravity of the situation, the swift actions of the awakened captain averted disaster, emphasizing the necessity for robust safety protocols and measures within the aviation industry.

In a symbolic transition marking the end of a storied chapter in aviation history, Air India bid farewell to its last remaining Boeing 747-400 jumbo jetliners, once revered for ferrying dignitaries including prime ministers, presidents, and vice presidents.

The sale of these iconic aircraft to AerSale, a company based in the United States, signals the closure of a remarkable era for the airline.

The decision to part ways with the Boeing 747s was driven by practical considerations. Tata Group, the new custodian of airindia flights, deemed these majestic planes uneconomical to operate in today’s aviation landscape. As such, out of the four sold, two will be repurposed into freighters, while the remaining pair will be meticulously disassembled to harness their valuable parts.

The transaction, orchestrated by Mumbai-based Vman Aviation Services, underscores the strategic shift in Air India’s fleet management strategy under its new ownership. Tata Group’s decision to divest from the 747s reflects a commitment to optimizing operational efficiency and aligning with contemporary industry standards.

Skytech-AIC, a UK-based remarketing firm engaged by Tata Group, facilitated the sale of these iconic aircraft, marking the conclusion of their illustrious service with Air India. The airline’s last flight featuring the Boeing 747 took to the skies between Delhi and Mumbai in March 2021, encapsulating decades of distinguished service and indelible memories.

The allure of used aircraft parts continues to resonate across the aviation sector, offering operators a cost-effective alternative without compromising on quality or performance. The transfer of these aircraft to AerSale not only ensures their continued utility but also underscores the enduring legacy of Air India’s fleet.
