Narrative:
Aircraft was performing far 25 icing tests in intermittent maximum conditions. Prior to flight, the spin chute had been tested and then set in a dearmed state. During the icing test procedure, static was heard in the headsets, and a dull thump was felt. It was assumed the engine had experienced a compressor stall so the mission was terminated. Postflt inspection revealed that the spin chute motor had fired and departed the aircraft.

Title: A CRJ700 ON AN ICING TEST FLT IN CRUISE AT 17000 FT DIVERTED DUE TO ENCOUNTERING AUDIO STATIC AND A DULL THUMP CAUSED BY A SPIN CHUTE DEPARTING THE ACFT.
Narrative: ACFT WAS PERFORMING FAR 25 ICING TESTS IN INTERMITTENT MAX CONDITIONS. PRIOR TO FLT, THE SPIN CHUTE HAD BEEN TESTED AND THEN SET IN A DEARMED STATE. DURING THE ICING TEST PROC, STATIC WAS HEARD IN THE HEADSETS, AND A DULL THUMP WAS FELT. IT WAS ASSUMED THE ENG HAD EXPERIENCED A COMPRESSOR STALL SO THE MISSION WAS TERMINATED. POSTFLT INSPECTION REVEALED THAT THE SPIN CHUTE MOTOR HAD FIRED AND DEPARTED THE ACFT.
