Aero Flight 311, operated by Aero Oy, took off from Helsinki on a routine domestic flight to Oulu. Onboard were 25 individuals, including passengers and crew. As the aircraft journeyed toward its destination, it encountered inclement weather characterized by heavy snowfall and reduced visibility. Reports indicate that the pilot attempted to maintain control but ultimately lost the ability to navigate effectively through the storm. The aircraft struck a heavily forested area near Kvevlax, resulting in a catastrophic accident. Emergency services responded promptly, but the crash site was remote, complicating rescue efforts. Unfortunately, all 25 occupants perished in the tragedy.

Following the accident, an investigation was initiated to determine the causes and contributing factors. The Finnish Civil Aviation Administration played a crucial role in assessing the circumstances surrounding the crash. Their findings revealed a need for stricter regulations regarding flight operations in adverse weather conditions. Aviation safety measures were subsequently enhanced, focusing on pilot training and operational protocols to ensure better preparedness in similar situations in the future. The incident served as a wake-up call for the aviation community in Finland, emphasizing the importance of risk management when faced with challenging weather conditions.
