Incident Overview
On an unspecified date, an aircraft departed from Luang Namtha Airport. During the takeoff roll, after reaching V1 speed, the crew initiated rotation. At that moment, the flight engineer decided to abort the takeoff procedure without coordinating with either pilot. The aircraft was unable to stop within the remaining runway distance, overran the end of the runway, and collided with a building.
Occupants and Casualties
All 35 occupants aboard the aircraft were rescued. One person on the ground was killed in the collision.
Probable Cause
According to the official investigation, the probable cause was that the crew failed to prepare the flight according to published procedures. Prior to departure, the crew incorrectly calculated the weight and balance, leading to the aircraft being incorrectly loaded with the center of gravity (CoG) too far forward, outside the allowable envelope. Poor crew coordination was identified as a contributing factor.
