Bad weather appears to have been a factor in two Let 410 fatal accidents. On 14 December an Eagle Air Let 410A (5X-CMF) crashed into the Geti hills around 22nm (40km) east of its take-off aerodrome at Bunya, in eastern Democratic Republic of Congo. All four passengers and two crew were killed. On 16 December a HeliAndes Let 410UVP (HK-4175X) hit the Il Silencio mountain in heavy rain and high wind only 4min after the take-off from Medellin, Colombia, killing both pilots and all 14 passengers.
