## Probable cause

the overstress fracture of the airplane's refueling adapter ring that resulted from the abnormal angular force applied to it.  The applied angular force occurred due to the ground refueler inadequately positioning the hydrant fuel truck (in relation to the airplane), and his inattentiveness while lowering the refueling lift platform, thus permitting the refueling hose to become snagged and pulled at an angle.  The fracture of the adapter ring during the refueling led to the ignition of the pressurized (mist producing) spilled fuel and subsequent fire.
