Incident
Shortly after takeoff from Dallas-Love Field Airport, the aircraft experienced an engine failure while climbing. The pilot elected to return to the airport for a safe landing, but the aircraft lost height and subsequently crashed into residences located near the airport. All seven occupants aboard sustained serious injuries, while no injuries occurred on the ground. The aircraft was destroyed by the impact.
Investigation
Investigators determined that the engine malfunction occurred during the initial climb phase. The subsequent collision with residences was attributed to improperly serviced aircraft by ground crew. Contributing factors identified in the investigation included the use of improper fuel grade, deficiencies in operational supervisory personnel, company-maintained equipment and services, and regulatory issues. Additionally, high obstructions in the area, partial loss of power on one engine, and complete engine failure on the same engine were reported. The forced landing occurred off airport on land. It was found that the truck used to refuel the airplane was intended to contain 100LL fuel but instead contained Jet A fuel. Furthermore, the fuel farm tank vent covers were improperly marked.
Probable Cause
The probable cause of the accident is engine malfunction during initial climb and subsequent collision with residences due to improperly serviced aircraft by ground crew.
