Narrative:

A swearingen model swiiib (the 'aircraft'), departed from santa flight engineer, NM, airport at XA15Z to its destination, centennial airport in denver, co. The flight was conducted at FL210 until we were instructed by ZDV to descend and contact den approach control. The flight continued pursuant to instructions from den approach control. We completed our descent and approach checklists and obtained the ATIS information, which indicated that we should expect runway 35R for landing. Den approach told us to complete a right 360 degree turn and continue the approach to runway 35R. After we completed the turn and were approximately 3 mi out on the approach to runway 35R, we were instructed to proceed to runway 28, apparently due to strong winds and poor braking conditions on runway 35R and runway 35L. Once established on final approach to runway 28, the control tower informed us that the wind was from 290 degrees at 22 KTS, with gusts to 28 KTS. I did not request, nor was I given, information regarding the braking/icing condition of runway 28. The approach and landing were normal and positive, including the first stage of deceleration. At 55 KIAS, the aircraft became uncontrollable and began to slide on the runway surface toward the left side of runway 28. The aircraft did not respond to rudder, steering, or brake inputs and the left main gear struck a snowdrift, causing the aircraft to depart the runway and decelerate. The aircraft sustained structural damage, but there were no injuries to the crew or passenger. The crew performed the appropriate emergency procedures and averted further damage or injury. Approximately 27 mins later, at XA51Z, a piston pwred, single engine beechcraft experienced the same problem. The beechcraft sustained structural damage and its occupant(south) apparently sustained injuries.

Title: SWEARINGEN IIIB ACFT LNDG ON ICY RWY. FLC LOST CTL AND DEPARTED OFF THE L SIDE OF THE RWY.

Narrative: A SWEARINGEN MODEL SWIIIB (THE 'ACFT'), DEPARTED FROM SANTA FE, NM, ARPT AT XA15Z TO ITS DEST, CENTENNIAL ARPT IN DENVER, CO. THE FLT WAS CONDUCTED AT FL210 UNTIL WE WERE INSTRUCTED BY ZDV TO DSND AND CONTACT DEN APCH CTL. THE FLT CONTINUED PURSUANT TO INSTRUCTIONS FROM DEN APCH CTL. WE COMPLETED OUR DSCNT AND APCH CHKLISTS AND OBTAINED THE ATIS INFO, WHICH INDICATED THAT WE SHOULD EXPECT RWY 35R FOR LNDG. DEN APCH TOLD US TO COMPLETE A R 360 DEG TURN AND CONTINUE THE APCH TO RWY 35R. AFTER WE COMPLETED THE TURN AND WERE APPROX 3 MI OUT ON THE APCH TO RWY 35R, WE WERE INSTRUCTED TO PROCEED TO RWY 28, APPARENTLY DUE TO STRONG WINDS AND POOR BRAKING CONDITIONS ON RWY 35R AND RWY 35L. ONCE ESTABLISHED ON FINAL APCH TO RWY 28, THE CTL TWR INFORMED US THAT THE WIND WAS FROM 290 DEGS AT 22 KTS, WITH GUSTS TO 28 KTS. I DID NOT REQUEST, NOR WAS I GIVEN, INFO REGARDING THE BRAKING/ICING CONDITION OF RWY 28. THE APCH AND LNDG WERE NORMAL AND POSITIVE, INCLUDING THE FIRST STAGE OF DECELERATION. AT 55 KIAS, THE ACFT BECAME UNCTLABLE AND BEGAN TO SLIDE ON THE RWY SURFACE TOWARD THE L SIDE OF RWY 28. THE ACFT DID NOT RESPOND TO RUDDER, STEERING, OR BRAKE INPUTS AND THE L MAIN GEAR STRUCK A SNOWDRIFT, CAUSING THE ACFT TO DEPART THE RWY AND DECELERATE. THE ACFT SUSTAINED STRUCTURAL DAMAGE, BUT THERE WERE NO INJURIES TO THE CREW OR PAX. THE CREW PERFORMED THE APPROPRIATE EMER PROCS AND AVERTED FURTHER DAMAGE OR INJURY. APPROX 27 MINS LATER, AT XA51Z, A PISTON PWRED, SINGLE ENG BEECHCRAFT EXPERIENCED THE SAME PROB. THE BEECHCRAFT SUSTAINED STRUCTURAL DAMAGE AND ITS OCCUPANT(S) APPARENTLY SUSTAINED INJURIES.
