The airplane departed Kathmandu-Tribhuvan Airport at 1111LT, carrying technical engineers and staff of the airline. The airplane was ferried to Pokhara to proceed with a C-check maintenance program. Less than two minutes after takeoff from runway 02, the crew encountered an unexpected situation when the airplane rolled to the right, went to an almost vertical attitude before it crashed 200 meters to the right of the runway centerline, bursting into flames. The captain was seriously injured while 18 other occupants were killed.

The airplane departed Kathmandu-Tribhuvan Airport at 1032LT on a schedule service (YT691) to Pokhara, carrying 68 passengers and a crew of four. On final approach to Pokhara Airport in excellent weather conditions, the airplane entered a slight pitch up attitude, rolled to the left up to 90° (the left wing apparently stalled) then crashed on the bank of the River Seti, bursting into flames. The airplane was totally destroyed and the wreckage was found about 1,9 km short of runway 12 of the new Pokhara International Airport that was open to traffic January 1st, 2023. Part of the debris were found on the top of the hill and others down in the river bed. No one is believed to have survived the crash.

On 29 May 2022, Tara Air’s 9N-AET, Twin Otter (DHC-6/300) aircraft was scheduled for three flights on Pokhara-Jomsom-Pokhara sector. Tara Air had also filed flight plans for two additional Charter flights on the same sector. Among those five flights, four flights were to be conducted by a set of crews already positioned at Pokhara while the last flight was scheduled to be commanded by the PIC who had reached Pokhara from Kathmandu that very morning. Since Jomsom Airport was closed for operations due to bad weather, the PIC went to Tara Air crew camp and waited for the updates of weather improvement of Jomsom. After Jomsom Airport was open for operations at 0321 UTC, Tara Air operation decided to operate the first scheduled flight. However suspecting the next flight operation to Jomsom could not be operated, the original PIC assigned to the flight seated on board as a passenger to Jomsom for his scheduled business trip and the PIC assigned for the last flight took command. The Flight Plan was amended accordingly. At 0342 UTC, Summit Air’s 9N-AKZ, LET-410 took-off from Pokhara to Jomsom. At 0405 UTC, it reported an altitude of 12,500 ft and patches of cloud over Tatopani. At 0409 UTC, Summit Air’s second aircraft 9N-AMG, LET-410, took-off for Jomsom and subsequently, at 0410 UTC, 9N-AET of Tara Air (TRA197) took-off with 19 passengers and three crews on board. The Copilot had initially reported 3 crew and 18 passengers onboard to Pokhara Tower but later, revised the passenger figure was 19 prior to takeoff. 9N-AET was supposed to take-off before SMT 601 but the PIC seemed hesitant to commence the flight due to weather PIREP from 9N-AKZ that, the en-route weather was not favorable for VFR flights and critical around LETE and TATOPANI. All the crew members of TRA 197 and SMT 601 were in their respective cockpits and communicating with the preceding flight 9N-AKZ as well as with Pokhara tower for the updated information of en-route and destination weather. No flights had been conducted since morning and most of the passengers of Tara air and Summit Air were already at airport. In this situation it can be assumed that there was pressure to conduct flight from each angle. While listening to the CVR of TRA 197, it was observed that someone, either ground staff or some intimate passenger to the crew, advising strongly to the PIC to conduct the flight. Following the PIREP from 9NAKZ, both TRA197 and SMT 601 subsequently started their engines to commence the flights. The PIC of TRA 197 was still hesitant to conduct the flight for Jomsom even after the engine start and delayed the taxi as he was not yet convinced about the weather report received from preceding 9N-AKZ aircraft. In the meantime, SMT 601 lined up for departure to Jomsom. That was one of the most important pressure points to the PIC of TRA 197 to initiate departure. TRA 197 finally lined up and took off from Pokhara at 0410 UTC following the SMT 601 based on the en-route weather information (VMC) from 9N-AKZ, through Pokhara Tower. The en-route weather provided by Summit Air’s 9N-AKZ to Pokhara Tower and the crewmembers of TRA 197 and SMT 601 was not the same. Aircraft took off from Pokhara from runway 04 heading North. Tower instructed “report 5 DME northwest RW 04”. Then after departure at 90 climb power aircraft turned left to maintain a heading of 345 and planned to join heading 305 degree towards Ghodepani. After four minutes, TRA 197 reported, “Now on course…. 6000 climbing and ETA Jomsom 32” (0432 UTC). At 04:21 TRA 197 reported to Pokhara Tower as position approaching Ghodepani 12000 climbing for 12500. After 6 Seconds ATC Pokhara asked TRA 197, “confirm would like to change level and TRA 197 replied, “No Ma'am we have crossed Ghodepani and like to be on”. Pokhara Tower instructed, “Tara 197 contact Jomsom Tower 122.5” CVR recordings show that after TRA 197 crossed Ghodepani, the PIC was not comfortable with the en-route weather. However, the flight was continued following the advice of SMT 601. At 0426 UTC, TRA 197made the first contact with Jomsom AFS and reported its position to which Jomsom Tower conveyed the prevailing weather as “Wind South Westerly up to 30 kts, QNH 1019, Temp 18º”. The PIC of TRA 197 reconfirmed twice if the wind was maximum, up to 30 Kts and currently South Westerly-25kts. The crew was discussing about the bad weather being encountered and the PIC himself voiced his dissatisfaction about the behavior of other pilots who conduct VFR flights in such unfavorable weather. The CVR recordings reveal that the aircraft was encountering clouds and the PIC was trying his best to remain clear of the clouds. During the course of flight, TRA 197 hadn’t reported any abnormalities encountered and neither any technical defect on aircraft either to Jomsom tower or Pokhara Tower. As per CVR, PIC was searching for light and brighter areas and adamantly heading towards it. As per CVR and V2 tracker data, the aircraft was maintaining 12000 ft and was in a climbing attitude. During the continuous attempts of crew to avoid the clouds with Terrain Avoidance and Warning System [TAWS] inhibited, the aircraft met with an unfortunate CFIT accident into the rocky terrain at an altitude of 4050 meter AMSL at Sanusare Mountain, Thasang Rural Municipality, Mustang. As per V2 tracker, last position of 9N-AET was 7.7 nm SW of Jomsom Airport. The aircraft was completely destroyed by the impact and there were no survivors.

On 14 April 2019, around 0322Hrs, Aircraft Industries' L410UPV-E20, registration 9NAMH, owned and operated by Summit Air Pvt. Ltd. met with an accident at Tenzing-Hillary Airport, Lukla when it veered right and excurred the runway during take-off roll from runway 24. The aircraft first collided with Manang Air's helicopter, AS350B3e, registration 9N-ALC, with its rotor blade running on idle power and then with Shree Airlines' helicopter, AS350B3e, registration 9N-ALK just outside the inner perimeter fence of the aerodrome into the helipad before coming to a stop. The PIC and Cabin Crew of 9N-AMH survived the accident, whereas the Co-pilot and one security personnel on ground were killed on the spot. One more security personnel succumbed to injury later in hospital during the course of treatment. 9N-AMH and 9N-ALC both were substantially damaged by impact forces. There was no post-crash fire. Prior to the accident the aircraft had completed 3 flights on Ramechhap-Lukla-Ramechhap sector. According to PIC, he was in the left seat as the pilot monitoring (PM) and the co-pilot, in the right seat was the pilot flying (PF). According to CCTV footages, the aircraft arrived at the apron from VNRC to VNLK at 0315Hrs and shut its LH engine. The PIC started the LH engine at about 0318 Hrs after unloading cargo and passengers. At 0322:30 Hrs, the PIC aligned the aircraft with the runway at the runway threshold 24 and then handed over the controls to the co-pilot for the take-off roll. The take-off roll commenced at 0322:50 Hrs. CCTV footage captured that within 3 seconds the aircraft veered right and made an excursion. The aircraft exited the runway and travelled about 42.8 ft across the grassy part on right side of runway 24, before striking the airport inner perimeter fence. It then continued to skid for about 43 ft, into the upper helipad, crashing into 9N-ALC. Eye witnesses statements, CCTV footages and initial examination of the wreckage showed that rotor blades of helicopter 9N-ALC were on idle when RH wing of the aircraft swept two security personnel (on ground) before slashing its rotor shaft. The moving rotors cut through the cockpit on the right side slaying the Co-pilot immediately. The helicopter toppled onto the lower helipad 6 ft below. The LH wing of the aircraft broke the skid of helicopter 9NALK and came to a halt with toppled 9N-ALC beneath its RH main wheel assembly. Due to 2impact, 9N-ALK shifted about 8 ft laterally and suffered minor damages. There was no post-crash fire. The PIC switched off the battery and came out of the aircraft through emergency exit along with the cabin crew. The captain of the helicopter 9N-ALC was rescued immediately. 9N-ALC's crew sustained a broken tail-bone whereas 9N-ALK's crew escaped without sustaining major injuries. All three deceased were Nepalese citizens. Aircraft 9N-AMH and helicopter 9N-ALC were substantially damaged while the helicopter 9N-ALK endured partial damages.

The single engine aircraft departed Surkhet Airport at 0612LT on a cargo flight to Simikot. At 0627LT, the crew made his last radio transmission with Nepalgunj Tower. About 18 minutes later, while cruising by night at an altitude of 12,800 feet, the airplane struck the slope of a mountain located near the Simikot Pass, some 12 km from Simikot Airport. The airplane disintegrated on impact and both crew members were killed.

On March 12, 2018, a US Bangla Airlines, Bombardier DHC-8-402, S2-AGU, flight number BS211 departed Hazrat Shahjalal International Airport, Dhaka, Bangladesh at 06:51 UTC on a schedule flight to Tribhuvan International Airport (TIA), Kathmandu, Nepal. The aircraft overflew part of Bangladesh and Indian airspace en-route to Nepal. At 0641, Dhaka Ground Control contacted the aircraft requesting for its Bangladesh ADC number which was recently made mandatory a few weeks ago by Bangladesh authority for all international outbound flights. The crew provided the ADC number as 2177 as provided in the Flight Plan. The Ground Controller again asked the crew if they had the ADC for Bangladesh. At 0642, PIC then contacted the Operations to confirm the Bangladesh ADC number. As per the CVR records, changes in the PIC’s vocal pitch and language used indicated that he was agitated and experiencing high levels of stress at the time while communicating with Dhaka Ground Control and airlines operations. The aircraft finally took off at 0651. As the aircraft was in a climb phase, the PIC overheard a communication between Operations and another US Bangla aircraft regarding the fuel onboard but the PIC without verifying whether the message was meant for him or not, engaged in some unnecessary conversation with the Operations staff. The Captain's vocal pitch and language used indicated that he was very much emotionally disturbed and experiencing high level of stress. The aircraft established its first contact with Kathmandu Control at 0752:04. At 0807:49 the First Officer contacted Kathmandu Control and requested for descent. Kathmandu Control gave descend clearance to FL160 with an estimated approach time of 0826 which was acknowledged by the First Officer. At 0810 the flight was handed over to Kathmandu Approach. At 0811, Kathmandu Approach instructed the aircraft to descend to 13,500 ft and hold over GURAS. The crew inserted the HOLD in the Flight Management System. At 0813:41 Kathmandu Approach further instructed the aircraft to reduce its speed and descend to 12500 ft. At 0816 Kathmandu Approach instructed the aircraft to further descend to 11500 ft., and cleared for VOR approach RWY 02 maintaining minimum approach speed. Both the crew forgot to cancel the hold on the FMS as they were engaged in some unnecessary conversation. Upon reaching GURAS, the aircraft turned left to enter the holding pattern over GURAS, it was noticed by PIC and FO and immediately PIC made correction and simultaneously this was alerted to the crew by Approach Control also. Once realizing the aircraft flying pattern and ATC clearance, the PIC immediately selected a heading of 027° which was just 5° of interception angle to intercept the desired radial of 202° inbound to KTM. The spot wind recorded was westerly at 28kt. The aircraft continued approach on heading mode and crossed radial 202° at 7 DME of KTM VOR. The aircraft then continued on the same heading of 027° and deviated to the right of the final approach course. Having deviated to the right of the final approach path, the aircraft reached about 2-3 NM North east of the KTM VOR and continued to fly further northeast. At 0827, Kathmandu Tower (TWR) alerted the crew that the landing clearance was given for RWY 02 but the aircraft was proceeding towards RWY 20. At 0829, Tower Controller asked the crew of their intention to which the PIC replied that they would be landing on RWY 02. The aircraft then made an orbit to the right. The Controller instructed the aircraft to join downwind for RWY 02 and report when sighting another Buddha Air aircraft which was already on final for RWY 02. The aircraft instead of joining downwind leg for RWY 02, continued on the orbit to the right on a westerly heading towards Northwest of RW 20. The controller instructed the aircraft to remain clear of RWY 20 and continue to hold at present position as Buddha air aircraft was landing at RW 02 (from opposite side) at that time. After the landing of Buddha Air aircraft, Tower Controller, at 08:32 UTC gave choice to BS211 to land either at RW 20 or 02 but the aircraft again made an orbit to the right, this time northwest of RWY 20. While continuing with the turn through Southeastern direction, the PIC reported that he had the runway in sight and requested tower for clearance to land. The Tower Controller cleared the aircraft to land but when the aircraft was still turning for the RWY it approached very close to the threshold for RWY 20 on a westerly heading and not aligned with the runway. At 08:33:27 UTC, spotting the aircraft maneuvering at very close proximity of the ground and not aligned with the RWY. Alarmed by the situation, the Tower Controller hurriedly cancelled the landing clearance of the aircraft by saying, "Takeoff clearance cancelled". Within the next 15-20 seconds, the aircraft pulled up in westerly direction and with very high bank angle turned left and flew over the western area of the domestic apron, continued on a southeasterly heading past the ATC Tower and further continued at a very low height, flew over the domestic southern apron area and finally attempted to align with the runway 20 to land. During this process, while the aircraft was turning inwards and momentarily headed towards the control tower, the tower controllers ducked down out of fear that the aircraft might hit the tower building. Missing the control tower, when the aircraft further turned towards the taxi track aiming for the runway through a right reversal turn, the tower controller made a transmission by saying, "BS 211, I say again...". At 08:34 UTC the aircraft touched down 1700 meters down the threshold with a bank angle of about 15 degrees and an angle of about 25 degrees with the runway axis (approximately heading Southeast) and to the left of the center line of runway 20, then veered southeast out of the runway through the inner perimeter fence along the rough down slope and finally stopped about 442 meters southeast from the first touchdown point on the runway. All four crew members (2 cockpit crew and 2 cabin crew) and 45 out of the 67 passengers onboard the aircraft were killed in the accident. Two more passengers succumbed to injury later in hospital during course of treatment. The aircraft caught fire after 6 seconds of touchdown which engulfed major portions of the aircraft.

The crew departed Surkhet on a flight to Simikot but was unable to land at Simikot due to high winds and diverted to Bajura Airfield. Upon arrival, the twin engine aircraft crashed and came to rest upside down. The captain was killed and both other crew members were seriously injured.

On May 27, 2017 9N-AKY, LET 410 UVP-E20 of Goma Air (now Summit Air), a domestic carrier of Nepal had a published program to operate 5 flights to Lukla from Kathmandu. The first flight departed Kathmandu at 0026 UTC. By the time 0647 UTC they had completed 4 flights. The fifth and the last flight departed Kathmandu at 0744 UTC for Lukla as call sign Goma Air 409. Goma Air 409 was the cargo flight carrying 1680 kg cargo for Lukla. There were two cockpit crews, one cabin crew and no passengers on board the flight. It was pre-monsoon period. Lukla weather on that particular day was cloudy since morning. But ceiling and visibility were reported OK. However, CCTV footage shows rapidly deteriorating weather condition before and after the crash. Automatic VHF recorder of Lukla Tower and CVR recording showed Tower was regularly updating pilots of deteriorating weather. All the pre-and post-departure procedure of the flight was completed in normal manner. Before departure from Kathmandu Pilots were found to have obtained latest weather of Lukla, Phaplu and Rumjatar. PIC decided to remain south of track to avoid the terrain and cloud. When Goma 409 was about 11 miles East from Kathmandu they were informed that Lukla was having heavy rain and airport closed. By that time air traffic congestion in TIA was slowly developing. Traffics were holding in the air and in the ground as well. So Goma 409 continued for Lukla. However, after crossing 26 miles from Kathmandu, they were again informed that the rain had ceased and airport was open. An AS350 helicopter, 9N AGU which departed Lukla at 0803 UTC for Kathmandu had reported unstable wind on final Runway 06. Enroute weather reported by 9N AGU upon request of Lukla Tower was good beyond the Lukla valley. However, it was apprehended that for fixed wing, weather might be difficult to enter valley. Lukla Tower relayed all available information when Goma Air 409 had first established contact at time 0810 UTC. Later, Goma Air and 9N AGY, two reciprocal traffics were also in contact each other. 9N AGY relayed the actual weather status to GOMA AIR. Lukla valley's ceiling and visibility was OK for VFR until 0812UTC ( 6 minutes before crash). Weather started to deteriorate very fast. Mountain Ridges were visible through thin layer of foggy cloud until 0814 UTC. After one minute (approx.) Right Base for Runway 06, was covered up and cloud from left base was moving towards final. Duty ATS Officer of Lukla Tower was regularly up dating pilots about deteriorating weather condition. However, Tower was found to be failed to close the runway as per SOP in spite of rapidly deterioratingweather. Pilots ventured to continue though the weather was marginal. Aircraft reported entering valley at 0816. CVR record showed that First Officer sighted the runway at 0817 (64 seconds before the impact). Instantly PIC acknowledged he had also the runway in sight. Aircraft was at 9100 ft (approx.) when the cockpit crews sighted the runway. It maintained 9000 feet (approx.) for further 21 seconds. At time 0817:12i.e. 48 seconds before the impact Tower gave the latest wind as Westerly 04 knots and runway was clear. PIC was still in doubt and asked whether there was rain. Upon confirmation of having no rain from the Tower the aircraft started to descend further. The PIC, who was also the PF, found to have lost situational awareness deviated to the right with continued descend. At 0817:35 (25 seconds before impact) when the flight was descending through 8650 ft First Officer warned PIC that they were too low. PIC did not respond the F/O's call-out and continued descend. On reaching 8500 ft. F/O again warned PIC in panic. Then PIC asked in panic where the runway was. F/O directed towards the runway. But it was already too low and too late. There was initially two short stall warning sound. Then a continuous stall warning sounded till the impact, which lasted for 13 seconds. The last words in CVR records was "w]/ gtfg " (Do not pull too much). Abrupt change in aircraft attitude in an attempt to climb and reach threshold height at 8900 ft. (on Kathmandu QNH) in a landing configuration, with landing gears down and on full flaps, created excessive drag resulting the aircraft to stall. Subsequently, its left wing first hit a small tree branch 180 ft. short of the threshold. Then impacted the sloppy terrain 100ft. short of the runway. After the crash aircraft engine was reported to be running for about a minute. But there was no postcrash fire. Aircraft was totally damaged by the impact.

The approach to Siddharthanagar-Gautam Buddha Airport was completed in good weather conditions with a wind from the southeast at 4 knots and a 8 km visibility. After touchdown on runway 28, the twin engine aircraft was unable to stop within the remaining distance. It overran, lost its undercarriage and came to rest in bushes, some 110 metres past the runway end. All 32 occupants evacuated safely and the aircraft was damaged beyond repair.

The single aircraft departed Nepalgunj at 1230LT bound for Jumla. About 35 minutes into the flight, the crew encountered an unexpected situation and attempted an emergency landing in a field. The aircraft eventually collided with an earth bank and came to rest near the village of Chilkhaya. Both pilots were killed and all 9 passengers were injured. The aircraft destroyed.
