The Civil Aviation Authority of Nepal reported that the airplane was on a flight to Pokhara. One survivor, the captain, was brought to hospital, 18 were found deceased stating: "Shortly after takeoff from runway 02 the aircraft veered to the right and crashed at the east side of the runway. Rescue operations were initiated immediately. The fire was brought under control, one injured person (the captain) was rescued and taken to a hospital and 18 people were found dead."
According to the airport of Kathmandu the aircraft carried 2 pilots, 17 technicians but no passengers on a flight to Pokhara where maintenance was to be done.
The airline confirmed all people on board were airline employees.
Saurya Airlines are a Nepalese operator founded in 2014 operating a number of jets (CRJ-200) connecting 5 domestic Nepal destinations.
On Sep 6th 2024 Nepal's AAIC released their preliminary report summarizing the sequence of events:
The aircraft had been grounded for 34 days before the event flight. The preservation and return to service maintenance checks were carried out. During grounding, the aircraft was parked at the remote parking bay. The aircraft was returned to the domestic parking bay on July 23, 2024.
On the event day, the aircraft lined up on runway 02 at VNKT at around 05:25:35 UTC and prepared for the commencement of take-off roll. The provided V-speeds were V1 = 114 knots, VR = 118 knots and V2 = 125 knots. By 05:25:55 UTC, the recorded weight-on-wheels (WOW) parameter for the nose, left and right landing gears had transitioned from ground to air. After rotation, the aircraft rolled to the right prompting the subsequent events leading up to the accident. The sequence of events is elaborated in Section 2 of this report below. Both stick shakers switched between ‘Active’ and ‘Not Active’ multiple times from 05:25:58 UTC to 05:26:04 UTC. The time of the first impact of the right wing on the ground was at around 05:26:10 UTC.
The captain (35, ATPL, 6185 hours total, 4922 hours on type) was assisted by a first officer (26, CPL, 1824 hours total, 1602 hours on type).
According to the load sheet the aircraft's takeoff weight was 18,132kg including 600kg of luggage and 2000kg of fuel. The center of gravity was at 20% MAC and the stabilizer setting was at 6.
The report does not mention the flap setting and actual flap positions, however, reports: "The V-speeds mentioned in the operation flight plan of the event flight, as well as recorded in the FDR, were inconsistent with the Quick Reference Handbook (QRH)."
The AAIC stated based on CCTV surveillance images and FDR data:
Almost immediately after rotation, the aircraft first went into a right wing down attitude, followed by left wing down-right wing down sequence. In the duration while the aircraft oscillated about its longitudinal axis, the pilot-in-command (also the pilot flying), provided a series of inputs to the control wheel to correct the aircraft attitude.
Summarizing the first FDR assessment the AAIC stated:
After rotation for take-off at 05:25:55 UTC, the aircraft attained a height of 50 ft above ground level (AGL) within 5±1 seconds. The height from the radio altimeter and pressure altimeter is shown in Figure 8, which indicates that the aircraft attained a height of slightly above 100 ft AGL by 05:26:03 UTC (marked ‘G’ in Figure 5, and at t= 410 s in Figure 8). At ‘G’, the aircraft was at 94.6° roll angle with a heading of 24.7°, veering right of Runway 02.
As per the preliminary analysis of the FDR data, no abnormalities were observed on engine parameters during the flight. Further analyses of all engine parameters are currently being performed.
During rotation for take-off, an abnormally high pitch rate was observed in the FDR data, of upto 8.6 degrees-per-second. As per the aircraft’s flight manual, a take-off pitch rate exceeding 3 degrees-per-second is considered excessive.
