SMA WITH STALL CONVERSION AND WHEEL; SKI EQUIP HAS CTL PROB ON APCH TO LNDG. LOSES CTL; WING TOUCHES GND.

Narrative

I DEPARTED BARROW WILEY POST ARPT IN SMA WITH A CONVERSION STALL KIT AND WHEEL SKI. THE FLT WAS UNEVENTFUL UNTIL REACHING THE FIRST OF 2 DESTS. I FLEW OVER THE NAYACAK FISH CAMP; LOCATED ON THE WAY RIVER; AND LOWERED TO 300 FT AGL TO EXAMINE AN AREA S OF THE CABIN. I REDUCED THE PWR TO 15 INCHES MP AT 2400 REVOLUTIONS. AFTER APPLICATION OF 3 NOTCHES OF FLAPS; I BEGAN TO PUMP THE SKIS DOWN. AT THAT MOMENT; THE ACFT VIOLENTLY ROLLED TO THE L. AS THIS WAS THE FIRST INDICATION OF A STALL CONDITION; THE STALL WARNING HORN DID NOT SOUND. FULL PWR WAS APPLIED AND FLAPS WERE REDUCED TO 2 NOTCHES; AND THE ACFT CONTINUED TO ROLL TO THE L. THE INITIAL BANK WAS ESTIMATED AT 50 DEGS. THE L WING CONTACTED THE TUNDRA; AND DURING THE ROLL SEQUENCE; THE L LNDG GEAR ALSO IMPACTED THE GND. CTL AT THIS POINT WAS VERY DIFFICULT. THE TIME TO RECOVER WAS APPROX 1 MIN. FROM THE COCKPIT I COULD SEE THE L PLASTIC WINGTIP HANGING BY THE POS LIGHT WIRES; WHILE THE R SIDE APPEARED OK. THE LNDG GEAR ALSO APPEARED TO BE UNHARMED. THE FLT WAS IMMEDIATELY RETURNED TO BARROW AND RPTED FIRST TO MAINT; AND COMPANY PERSONNEL.
