On April 2, 2019, about 1732 central daylight time, an experimental, amateur-built Berkey S-6ES airplane, impacted vegetation on final approach at a private turf airstrip near Lafe, Arkansas. The pilot was not injured and the airplane was substantially damaged. The airplane was registered to and operated by the pilot as a Title 14 Code of Federal Regulations Part 91 personal flight. Day visual meteorological conditions prevailed for the flight, which was not operated on a flight plan. The flight originated from the Blytheville Municipal Airport (HKA), Blytheville, Arkansas, about 1700. The private airstrip was the intended destination. The pilot reported that he was relocating the airplane from HKA to be based at the private airstrip which was closer to his home. He made one low pass over the field before returning to land. On final approach, he was "blinded by [the] sun" and the tailwheel hit vines growing near the airstrip which caused the airplane to stall. The left wing struck the ground resulting the substantial damage. In addition, the left main landing gear and propeller were damaged during the hard landing. The pilot noted that there were no mechanical failures or malfunctions associated with the airplane. He added that the accident might have been prevented by either landing at a later time so that the sun would not have "blinded" him or by clearing the vegetation near the runway to ground level. Information received from the Federal Aviation Administration indicated that the pilot did not hold a current pilot or medical certificate at the time of the accident. The pilot was initially issued a combined third-class medical and student pilot certificate in August 1994 by an aviation medical examiner. However, upon further review by the FAA, additional information unrelated to any medical deficiency was requested from the pilot. When the requested information was not received, the pilot was determined to be ineligible for a medical certificate and the application was denied. No other medical or pilot certificate applications were on file. The airplane was issued an experimental airworthiness certificate and met the requirements for operation as a light sport airplane. Regulations required pilot and medical certification in order to operate the airplane. Specifically, any individual operating a light sport airplane must hold a sport pilot or higher level of certification, or a current student pilot certificate with the applicable endorsements. In addition, a light sport airplane may be operated based on a valid driver's license provided the pilot was determined to be eligible for a medical certificate at the time of his/her most recent application, and not had his/her most recently issued medical certificate suspended or revoked. Because the pilot did not hold a current pilot certificate, nor did he meet the medical certification requirements, he was not legally authorized to act as pilot-in-command of the airplane at the time of the accident.
