US-Bangla Airlines Flight 211, a Bombardier Dash 8 Q400, was on a domestic flight from Dhaka, Bangladesh to Tribhuvan International Airport in Kathmandu, Nepal. While attempting to land on March 12, 2018, the aircraft lost control and crashed onto the runway, resulting in a catastrophic incident. Of the 71 individuals onboard, 51 people lost their lives including passengers and crew members, while 20 others sustained serious injuries. This accident marked one of the deadliest aviation disasters in Nepal in recent years.

The investigation into the crash revealed several contributing factors, including poor weather conditions, difficulties with air traffic control, and potential errors by the flight crew. The aircraft had reportedly circled the airport multiple times before making its landing approach. Eyewitness accounts confirmed that the plane appeared to overshoot the runway, leading to significant damage and destruction upon impact. Emergency response efforts were immediate, although the injuries and fatalities were severely pronounced due to the incident's severity.

In the wake of the crash, there were heightened concerns regarding aviation safety in Nepal, which has a history of aviation incidents mainly due to challenging mountainous terrains and variable weather conditions. This incident prompted discussions about the regulatory framework for airlines operating in the region as well as the need for improved training for pilots and air traffic control staff to prevent future accidents. The government of Nepal pledged to review and revise safety standards in domestic aviation, aiming to enhance passenger safety for future flights.
