Yeti Airlines flight 691, an ATR 72-500, crashed while on final approach to runway 12 at Pokhara International Airport, Nepal.
The aircraft crashed on the bank of Seti River and partially ended up in a deep gorge, killing all 72 on board.

The flight was operated by two captains, one captain was in the process of obtaining aerodrome familiarization for operating into Pokhara and the other captain being the instructor pilot. The captain being familiarized, 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).
They had operated two sectors between Kathmandu and Pokhara earlier in the morning.
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. At a later time, the flight crew requested and received clearance from ATC to land on runway 12.

At 10:51:36, the aircraft descended from 6,500 feet and joined the downwind track for runway 12 to the north of the runway.
The aircraft was visually identified by ATC during the approach. At 10:56:12, the pilots extended the flaps to the 15 degrees position and selected the landing gears lever to the down position. The take-off (TO) setting was selected on power management panel.
At 10:56:27, the PF disengaged the Autopilot System (AP) at an altitude of 721 feet Above Ground Level (AGL). The PF then called for "FLAPS 30" at 10:56:32, and the PM replied, "Flaps 30 and descending". The flight data recorder (FDR) data did not record any flap movement at that time.
Instead, the propeller rotation speed (Np) of both engines decreased simultaneously to less than 25% and the torque (Tq) started decreasing to 0%, which is consistent with both propellers going into the feathered condition. This was followed by a single Master Caution chime.
The flight crew then carried out the "Before Landing Checklist" before starting the left turn onto the base leg. During that time, the power lever angle increased from 41% to 44%. At the point, Np of both propellers were recorded as Non-Computed Data (NCD) in the FDR and the torque (Tq) of both engines were at 0%.

At 10:56:50 when the radio altitude callout for five hundred feet was annunciated, another 'click' sound was heard, likely the crew had inhibited the master caution light.
The aircraft reached a maximum bank angle of 30 degrees at this altitude. 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 on whether to continue 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 flaps surface movement to the 30 degrees position.
When ATC gave the clearance for landing at 10:57:07, the PF mentioned twice that there was no power coming from the engines. At 10:57:11, the power levers were advanced first to 62 degrees then to the maximum power position.
It was followed by a 'click' sound at 10:57:16. One second afterwards, the aircraft was at the initiation of its last turn at 368 feet AGL, the high-pressure turbine speed (Nh) of both engines increased from 73% to 77%.
At 10:57:18 the PF handed over control of the aircraft to the PM and the PM (who was previously the PF) repeated again that there was no power from the engines. At 10:57:24 when the aircraft was at 311 feet AGL, the stick shaker was activated.
At 10:57:26, a second sequence of stick shaker warning was activated when the aircraft banked towards the left abruptly. Thereafter, the radio altitude alert for two hundred feet was annunciated, and the cricket sound and stick shaker ceased. At 10:57:32, the aircraft impacted the ground.

The Pokhara International Airport was opened on January 1, 2023 and is located to the east-southeast of the old Pokhara Airport.
