What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On August 26, 2016, at approximately 3:15 pm eastern daylight time (1915Z), a Cessna 140, N2614N, sustained substantial damage on landing at the Boone County Airport, Lebanon, Indiana, (6I4) when it flipped over on its back. The pilot and passenger were not injured. The aircraft is registered to computer systems flight inc., and operated under the provisions of title 14 code of federal regulations (CFR) part 91 as a personal, sightseeing flight. Visual meteorlogical conditions prevailed and no flight plan was filed or required. The flight departed from frankfort, Indiana (fkr) at approximately 3:00 pm EDT (1500Z) with the intention of landing at 6I4.
The pilot stated the aircraft touched down on dry grass, rolled out 400-500 ft and then "hit a puddle." The aircraft slowly tipped over and came to rest on its back.
An examination of the grass field, where the aircraft landed, revealed an oval-shaped area of standing water measuring approximately 25 feet wide and six inches deep. This was invisible, according to the pilot, when he surveyed the airfield.
The existence of the grass strip is local knowledge or a local-use runway. The airport and governing authorities do not report the surface conditions.
