The pilot contacted his friend and told him to be at the beach and watch for the airplane. The friend reported that he saw the airplane make about three passes up-and-down the beach. On the third pass he said the airplane made a steep left turn, which he believed resulted in a stall. The airplane impacted the water, just offshore. Several other witnesses responded and aided in removing the pilot from the airplane and water. The airplane’s forward fuselage was heavily damaged during the impact and came to rest in about 5 feet of water. The pilot reported that as he arrived at the peninsula, he proceeded across the shoreline and then crossed the beach; he dropped to an altitude of approximately 100 feet. He added that he made a right turn, then after passing the bridge, he made a tight left turn and “felt a bump/drop, as if my left wing lost lift”. He added that he leveled off, slightly nose high, and headed in an east, south east direction. The pilot could not recall any further details of the accident.
