What happened
A twin-engine aircraft was performing a specialized flight on behalf of the US Air Force, traveling from Quảng Ngãi to Đà Nẵng with a scheduled stop at Tam Kỳ Airport. During the climb phase following departure from Tam Kỳ, the aircraft experienced a failure in one of its engines.
In response to the loss of power, the pilot attempted an emergency landing. During this maneuver, the twin-engine aircraft collided with a dirt embankment, resulting in a post-impact fire. The accident resulted in four fatalities and left four individuals injured.
Findings
The investigation determined that the primary factor leading to the crash was an engine failure occurring during the initial climb after takeoff.
