Accidents & Serious Incidents at or in vicinity of VNKT

  • A333, Kathmandu Nepal, 2015 (On 4 March 2015, the crew of a Turkish Airlines A333 continued an automatic non precision RNAV approach below the prescribed minimum descent altitude without having obtained any element of visual reference and when this was acquired a few seconds before the attempted landing, the aircraft was not aligned with the runway centreline and during a 2.7g low-pitch landing, the left main gear touched down on the grass. The aircraft then left the runway completely before stopping with a collapsed nose gear and sufficient damage to be assessed a hull loss. None of 235 occupants sustained serious injury.)
  • B739, Kathmandu Nepal, 2018 (On 19 April 2018, a Boeing 737-900 made a high speed rejected takeoff at Kathmandu in response to a configuration warning and overran the runway without serious consequences. The Investigation found that when a false Takeoff Configuration Warning caused by an out of adjustment switch had been annunciated just after V1, the Captain had decided to reject the takeoff because of concerns about the local terrain and locally adverse weather. It was noted that the aircraft operator did not provide criteria for rejecting takeoff up to or above the 80 knot crosscheck but that the Boeing reference QRH did so.)
  • D228, vicinity Kathmandu Nepal, 2012 (On 28 September 2012, control of a Sita Air Dornier 228 being flown by an experienced pilot was lost at approximately 100 feet aal after take off from Kathmandu in benign daylight weather conditions and the aircraft stalled without obvious attempt at recovery before impacting the ground where a fire broke out. All occupants were killed and the aircraft was destroyed. The comprehensive investigation found that insufficient engine thrust was being delivered to sustain flight but, having eliminated engine bird ingestion and aircraft loading issues, was unable to establish any environmental, airworthiness or loading issue which might have caused this.)
  • DH8D, Kathmandu Nepal, 2018 (On 12 March 2018, a Bombardier DHC8-400 departed the side of landing runway 20 at Kathmandu after erratic visual manoeuvring which followed a mis-flown non-precision approach to the opposite runway direction and was destroyed. The Investigation concluded that the accident was a consequence of disorientation and loss of situational awareness on the part of the Captain and attributed his poor performance to his unfitness to fly due to mental instability. A history of depression which had led to his release from service as a military pilot and a subsequent period of absence from any employment as a pilot was noted.)
