A "condensation stall" eh? Can somebody explain to me what a "condensation stall" is? People need to realize POGO is one of those groups with an agenda. This POGO reported was balanced out with some facts in the 10/31/05 issue of Aviation Week.
The basis of this report was a CV-22 on a ferry flight had suffered compressor stalling while in icing conditions. The engines cycled up and down several times. After the power fluctuations, the crew elected to make a precautionary landing. At no point did the engines "stall" or "fail." The CV-22 did have anti-icing systems installed, but they were not operational as testing on those systems has not been completed yet.
The aircraft (CV06) was at FL180 over Prescott, AZ when it encountered icing conditions and accumulated ice around the engine inlets. When the ice broke free and was ingested, the engines surged up and down. The aircraft did not stall or lose power and did not drop to 10,000'. After landing, the aircraft was found to have superficial damage on the tail and damaged first stage compressor blades.
