Rescue teams faced considerable challenges due to the swampy and treacherous terrain, taking nearly an hour to reach the crash site. Initial investigations are focusing on potential pilot error exacerbated by poor weather conditions or possible technical failures of the aircraft. The Antonov An-24 plane was nearing its 50th anniversary and had recently completed a technical inspection. However, it had a troubling history, including four prior incidents since 2018, raising safety concerns.

The aircraft had just commenced landing procedures after a previous unsuccessful attempt amid low cloud coverage when it lost contact with radar. Angara Airlines, which operates primarily in the Irkutsk region of Siberia, saw multiple services disrupted as its crew members were all local residents. The An-24 model itself has been noted for past accidents, including a severe incident in 2011 that led to calls for grounding similar aircraft in operation across Russia.
