The total loss of engine power due to oil starvation to the No. 1 connecting rod, which resulted from the improper torque of the No. 1 cylinder hold-down bolts and through-studs at the time of the cylinder's installation, which resulted in the failure of the connecting rod due to oil starvation. Contributing to the accident was the omission, from the air traffic control display map data, of a closer alternate airport for the emergency landing.
