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.
