(.4)The airplane was cleared to land on runway 19R at the Kansas City International Airport. The first officer said that the airplane was on speed and on course for the visual approach. 'The captain had just called the 1,000 feet above the ground call when a flock of snow geese suddenly illuminated in our lights, engulfing us from below, flying into us. No birds hit the windshields, but it was immediately apparent they had flown into the engines.' The captain said that he had the airplane, advanced the power on both engines, and ordered the first officer to reset the flaps to 30 degrees, the single- engine flap position. 'The number one engine continued to compressor stall. The number two engine went to a sub-idle run condition.' The captain reduced the power on the number one engine 'enough to lessen the surge/stall condition to a rate of once every two seconds, which allowed just enough thrust to maintain the approach and to lower the vibration. The number one engine continued to compressor stall/surge to touchdown.' The touchdown was normal. Examination of the airplane revealed bird remains and substantial damage to both engines. No other anomalies were found. (-23)on 3-4-99, at 2200 CST, a Douglas DC-9-15F, N195US, operated by usa jet airlines, inc., encountered a flock of large birds, while on final approach for landing at the Kansas City International Airport, Kansas City, MO. During the encounter, several birds were ingested into both engines, resulting in a severe power loss. The pilot managed to regain enough thrust on one engine to continue the approach and land the airplane without further incident. Night visual meteorological conditions prevailed at the time of the encounter. The flight was being conducted under 14 CFR part 121, non-scheduled, domestic air cargo service. An IFR flight plan was on file. The captain and first officer reported no injuries. (See attached page)
