NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

The airplane experienced a partial loss of power on both engines during takeoff. The flight returned and landed without further incident. Post accident examination of the engines revealed the compressor fan blades on both engines had sustained soft body impact damage. The airplane had been subjected to sub-zero temperatures during the previous flight and had landed with the wing tanks almost full. The airplane was on the ground for about two and a half hours prior to the accident takeoff during which time rain was falling. Both the captain and copilot reported that there were no signs of ice on the wings during their early morning preflight.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

the captains failure to have the airplane deiced prior to takeoff which resulted in ice ingestion into both engines. Factors associated with the accident were the icing weather conditions, wing ice, an inadequate detection of the ice during the preflight, and the dark lighting conditions when the first officer was performing the preflight.
