What happened
During the takeoff phase, the aircraft was operating at a weight exceeding its certified maximum gross weight by more than 500 pounds, representing an overload of approximately 12 percent. The takeoff roll commenced on a runway measuring 3,500 feet, with the aircraft becoming airborne roughly halfway to two-thirds of the way down the pavement.
Shortly after liftoff, the pilot performed the retraction of the flaps and landing gear. However, these actions were completed before the aircraft had reached the speeds recommended by the manufacturer for such maneuvers. Due to the combination of the heavy load and the premature configuration changes, the plane could not maintain enough altitude to clear obstacles. The flight path resulted in the aircraft striking trees and a residential building situated past the end of the departure runway.
Findings
An investigation of the wreckage and an analysis of the recorded non-volatile memory showed that there were no mechanical failures or abnormalities present prior to the impact. The primary contributing factors were the overweight condition of the aircraft and the pilot's decision to retract flight surfaces before reaching appropriate speeds.
