An Aeroservice Let L-410, registration RA-67075 performing flight NKZ-189 from Krasny Chikoy to Irkutsk (Russia), was on a 2-NDB approach to Irkutsk's runway 30 when the aircraft descended to 620 meters instead of published and approved 800 meters. ATC alerted the crew, who went around, positioned for another approach and landed safely on second approach.
On Sep 21st 2020 Rosaviatsia reported the descent was the result of a blunder, when the crew descended to 620 meters without coordination with ATC due to a mismatch of procedures in use. The crew referred to the NDB X approach runway 30 instead of the 2-NDB approach runway 30. The occurrence was rated an incident.
