Analysis

WHILE FLYING OFFSHORE SOUTHBOUND AT AN ALT OF 300-400 FT, THE BANNER TOWING BELLANCA PASSED TO THE RT, THE LAST OF A FLT OF FOUR BANNER TOWING SUPER CUB ACFT CRUISING AT ABOUT 40 MPH, PLACING THE ACFT CLOSER TO SHORE. WITH A QUARTERING TAILWIND, THE PLT INITIATED A 'VERY TIGHT' RT TURN TO RETURN NORTHBOUND. DURING THE TURN, THE ACFT DID WHAT WAS DESCRIBED AS A WING OVER & WHILE DESCENDING EASTBOUND WITH THE BANNER ATTACHED, THE MAIN GEAR CONTACTED A WAVE CAUSING THE ACFT TO NOSE INTO THE WATER. EXAMINATION OF THE ACFT & ENG REVEALED NO EVIDENCE OF FAILURE OR MALFUNCTION OF EITHER THE FLT CONTROLS OR ENG. THE BANNER RELEASE MECHANISM WAS EXAMINED & THERE WAS NO EVIDENCE OF FAILURE OR MALFUNCTION. THE MINIMUM ALT FOR BANNER TOWING OTHER THAN FOR PICKUP'S AND DROP'S IS 500 FT WHEN AUTHORIZED BY ATC.

Probable Cause and Findings

IN-FLIGHT LOSS OF CONTROL WHILE MANEUVERING TO REVERSE DIRECTION DUE THE FAILURE OF THE PILOT TO MAINTAIN ADEQUATE AIRSPEED DURING THE 'STEEP TURN.'
