What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On 06/06/2018, N100TN landed on lake winnebago near Pipe, WI. And taxied to the shoreline at 1830 CST.
The aircraft taxied out for take-off. On take-off, the pilot reported that the aircraft "began to oscillate ". The take-off was aborted and the aircraft taxied back to shore. Further inspection by the pilot revealed water in the hull of the aircraft. The aircraft bilge pump was utilized and the owner assisted with water removal from the belly of the aircraft.
The pilot taxied out for a second take-off and was able to break from the water. The owner reported that "the aircraft bounced 3-4 times after initial break from the water. On the fourth bounce, the aircraft violently pulled towards the left side and water rushed in everywhere". An inspection performed by the pilot revealed the hull had torn apart along with the left sponson. The aircraft stayed afloat due to the wings being above water and was towed to shore for inspection. No injuries were reported by the owner.
During a discussion with the pilot, the decision to make a second attempt at a take off was reviewed. The pilot stated he believed that the water was removed from the aircraft from the areas he could view. He stated it was his decision not to test the aircraft for leakage or perform a visual inspection of the entire belly of the aircraft. He stated he wanted to get "off the lake and back to his home base to inspect the aircraft."
VMC weather conditions were reported at the time of the accident with the following additional information: temp 71 degrees f, visibility> 10 miles, winds 240 degrees at 6 mph.
