A TAYLOR CRAFT FLOAT PLANE IS DAMAGED WHEN A STUDENT PLT WAS ATTEMPTING A STRAIGHT-AWAY TKOF PROC ON A CALM LAKE AT 2L6; AK.

Narrative

I BACK-TAXIED LELAN LAKE TO STIR UP THE GLASSY WATER CONDITION ON THE N 1/2 OF THE LAKE AND ATTEMPTED TAKING OFF STRAIGHT DOWN THE LAKE WITHOUT AN ARCING OR A STEP TURN. I GOT THE PLANE INTO GND EFFECT; BUT IT WOULDN'T GAIN AIRSPD. I DIDN'T THINK I COULD CLR THE TREES WITH THE AMOUNT OF LAKE I HAD LEFT AND ATTEMPTED TO LAND FROM GND EFFECT ALTS. THE PLANE STALLED AND DOVE L FROM ABOUT 8 FT OF ALT. THE FLOATS BROKE OFF; THE PROP STRUCK THE FLOATS AND THE PLANE SANK IN ABOUT 5 FT OF WATER. THERE WAS MINIMAL STRUCTURAL DAMAGE; BUT 1 FLOAT WAS HEAVILY DAMAGED. THERE WERE NO INJURIES AND THE PLANE WAS REMOVED FROM THE LAKE IN ABOUT 2 HRS. 3 FACTORS CONTRIBUTED TO THE INCIDENT: 1) I FLEW THE PLANE ONLY 1 1/2 HRS SINCE LAST YR AND DIDN'T DO AN ARCING OR STEP TURN WITH MARGINAL CONDITIONS OF GLASSY WATER; HIGH HUMIDITY AND NO WIND ON THE N 1/2 OF THE LAKE. 2) THE FLOATS RESISTED LEAVING THE WATER BECAUSE OF THE GLASSY CONDITIONS ON THE N 1/2 OF THE LAKE AND A SLIGHT XWIND BURBLING OVER TREES ON TOP OF MY PLANE. 3) THE FIRST 2 SITS PUT ME BEHIND THE PWR CURVE CAUSING A STALL.
