On August 5, 1995, at 1200 central daylight time, a Grumman G-164A, N732Y, was substantially damaged upon impact with obstructions while landing near St. Francisville, Louisiana. The commercial pilot was not injured. The aircraft was being operated as an aerial application flight by Air Care Farm Service Inc., under 14 CFR Part 137 when the accident occurred. Visual meteorological conditions prevailed and no flight plan was filed for the flight. According to the operator, the airplane was returning to the same pasture from which it had departed earlier for an aerial application flight. The operator added that the left main landing gear separated from the airframe after striking an obstruction while on short final. The airplane nosed over coming to rest in the inverted position damaging both wings. According to the operator report, the weather at the accident site differed from that reported at Baton Rouge, Louisiana, approximately 26 miles to the southeast. According to the operator a partial obscuration at 800 foot prevailed with visibility at one mile with light rain. Despite several requests, the pilot did not complete and return the NTSB forms 6120.1/2 provided by the investigator. The type of the obstruction impacted by the airplane on short final was never determined.
