3 people died.

The improper maintenance of the fuel servo resulting in a loose adjustment nut and subsequent failure of the fuel injection servo which led to a complete loss of power on the right engine. Other causes were the pilot's failure to obtain or maintain minimum controllable airspeed which resulted in an uncommanded roll and subsequent impact with the ground.

Read the full NTSB narrative

The airplane was destroyed when it impacted terrain following a loss of control after takeoff. A witness observed the airplane takeoff and then make a right turn that increased in bank angle until the airplane impacted the ground. Examination of the airplane's control system revealed no pre-impact abnormalities. Examination of the left engine revealed no pre-impact abnormalities. An examination and subsequent test run of the right engine revealed that the engine would not operate continuously with the installed fuel servo. A flow test of the fuel servo showed that the fuel flow was not within the manufacturer's specifications. Disassembly of the fuel servo showed that the fuel regulator nuts were loose and not the same as those originally supplied by the manufacturer. The measured drag torque of the regulator nuts was below the manufacturer's minimum specifications. An overhaul tag indicated that the fuel servo had been previously overhauled. A search of the aircraft records for the previous 5 years showed no record of the fuel servo being overhauled.
