Narrative:

I departed barrow wiley post airport in small aircraft with a conversion stall kit and wheel ski. The flight was uneventful until reaching the first of 2 destinations. I flew over the nayacak fish camp, located on the way river, and lowered to 300 ft AGL to examine an area south of the cabin. I reduced the power 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 aircraft violently rolled to the left. As this was the first indication of a stall condition, the stall warning horn did not sound. Full power was applied and flaps were reduced to 2 notches, and the aircraft continued to roll to the left. The initial bank was estimated at 50 degrees. The left wing contacted the tundra, and during the roll sequence, the left landing gear also impacted the ground. Control at this point was very difficult. The time to recover was approximately 1 min. From the cockpit I could see the left plastic wingtip hanging by the position light wires, while the right side appeared ok. The landing gear also appeared to be unharmed. The flight was immediately returned to barrow and reported first to maintenance, and company personnel.

Title: 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.
