On Monday, February 22, 1993, at approximately 1600 central standard time, a Grumman G 164B, N48455, was substantially damaged when it landed short of the runway and nosed over during the landing roll at Indian Village, Louisiana. The airplane, owned and operated by O'Brien Flying Service, and flown by a commercial pilot, was on a 14 CFR Part 137, local aerial application flight. There was no flight plan filed and visual meteorological conditions prevailed throughout the area. The pilot, the sole occupant, was not injured. Interviews with the operator by the Federal Aviation Administration (FAA) inspector and examination of the accident site by the FAA revealed the facts in this paragraph. The airplane touched down about 75 yards short of the asphalt airstrip. Shortly after touching down in the soft muddy terrain, the airplane nosed over. The pilot reported that the grass had been mowed and during the landing roll, the "grass started to pile up in front of the wheels and it caused the aircraft to flip." The airplane was released to the owner following the investigation.
