What happened
During the final approach phase of flight toward Dhahran Airport, a twin-engine aircraft experienced a sudden loss of altitude. The descent continued until the plane struck the summit of a hill situated a short distance from the airfield. The impact was severe enough to result in the total destruction of the airframe.
There were five fatalities recorded in the accident, as all occupants on board the aircraft perished during the crash event.
Findings
Official investigations into the accident considered various mechanical issues. Investigators did not dismiss the possibility that a failure of one of the engines led to the loss of control experienced by the crew prior to the impact.
