On March 26, 1999, at 1015 central standard time, a Grumman G-164B, agricultural airplane, N6758Q, impacted the terrain during the takeoff/initial climb near Jennings, Louisiana. The airplane was owned by Adams Flying Service, Inc., Rayville, Louisiana, and operated by Deep South Flying Service, Jennings, Louisiana, under 14 Code of Federal Regulations (CFR) Part 137. The commercial pilot, sole occupant, was not injured and the airplane sustained substantial damage. Visual meteorological conditions prevailed for the local aerial application flight that was originating at the time of the accident. A flight plan was not filed. During a telephone interview, conducted by the investigator-in-charge (IIC), and on the Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1/2) the operator reported that the airplane was loaded with fertilizer for application to the fields. The airplane "departed the north runway, turned to a southerly heading, stalled, and hit the ground." The airplane came to rest inverted. The wind was from the north at 10 to 12 knots. Structural damage occurred to the rudder, wings, and empennage.
