Belle Plaine, Minnesota 56011
Wednesday, April 12, 1995 9:58 CDT

NTSB Narrative Summary Released at Completion of Accident

THE INSTRUMENT RATED PRIVATE PILOT DECLARED AN EMERGENCY DURING INITIAL CLIMBOUT IN ICING CONDITIONS. NO OTHER TRANSMISSIONS WERE RECEIVED AND THE AIRPLANE WAS LOST FROM ARTCC RADAR AT 7300 FEET MSL. THE LEFT WING AND BOTH HORIZONTAL STABILIZERS SEPARATED IN FLIGHT, EXHIBITING PERMANENT DEFORMATION SUPPORTING POSITIVE OVERLOAD (STABILIZERS DEFLECTED DOWN, MAIN WINGS DEFLECTED UP). ALL THREE EMPENNAGE DEICE BOOTS WERE FOUND TO HAVE NUMEROUS PATCHES, WHICH WOULD NOT HOLD NORMAL SYSTEM PRESSURE. THE SYSTEM REQUIRED THE EMPENNAGE TO HOLD PRESSURE BEFORE IT WOULD CYCLE TO THE MAIN WINGS. REPLACEMENT OF THE BOOTS HAD BEEN RECOMMENDED TO THE OWNERS 3 MONTHS PRIOR. WITNESSES WHO ARRIVED ON SCENE IMMEDIATELY AFTER THE ACCIDENT DESCRIBED ICE ON THE WINGS AND BOOTS.

NTSB Probable Cause Narrative

the failure to replace the deteriorated deicing boots, and the failure of the boots to operate when the airplane encountered icing condition. An additional causes were the pilot's failure to maintain adequate airspeed and the excessive pullup performed by the pilot during the uncontrolled descent.
