NTSB Narrative Summary Released at Completion of Accident
On January 25, 2014, about 1515 Pacific standard time, an experimental Simpson Amphibeous Trike, N440LS, made a forced landing and came to rest on its side at the Chehalis-Centralia Airport (CLS), Chehalis, Washington. The pilot/owner operated the trike under the provisions of 14 Code of Federal Regulations Part 91, as a personal flight. The trike sustained structural damage to the left wing. The pilot, the sole occupant, was not injured. Visual meteorological conditions prevailed for the flight that was departing at the time and no flight plan had been filed. The flight was destined for the Toledo State Airport (5S4), Toledo, Oregon.
In an interview with the National Transportation Safety Board (NTSB) investigator-in-charge, the pilot reported that as soon as the trike lifted off the runway, it began to pull hard to the left. He looked to his left and saw the left wing flapping. He radioed that he was having a problem and flew a modified pattern to land. As the pilot turned the trike onto the final leg for landing, the trike began to oscillate in the air. As soon as it touched down, the left wing "grabbed" and the trike flipped over, coming to rest on its left side. The pilot stated that a police officer located the left wing spring assembly broken on the runway.
