On March 14, 2016, about 1000 eastern daylight time, a Grumman G-164B, N6654K, experienced a total loss of engine power and performed a forced landing to an agricultural field near Myakka, Florida. The commercial pilot was not injured. Visual meteorological conditions prevailed and no flight plan was filed for the aerial application flight, which departed a private grass strip in the vicinity of the agricultural field around 1000. The airplane was owned and operated by Southern Air Services, LLC and the maintenance test flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91.
According to the pilot, the purpose of the flight was to perform a "short" post maintenance flight to verify that the spray system was operating without anomaly. He performed a preflight inspection of the airplane and noted that it was "good to go." He started the airplane, and noted that during the takeoff that all the "gauges were in the green." Then, during the initial climb, the pilot adjusted the throttle and propeller controls, and the engine began to run "rough." Soon after, the engine lost total power and the pilot elected to land the airplane straight ahead in the field. The airplane touched down in the field, nosed over, and came to rest inverted.
A postaccident examination of the engine revealed that the engine remained attached to the airframe. In addition, engine continuity was confirmed and all cylinders remained attached to the engine. The supercharger exhibited rotational scoring and sand was located inside the housing. In addition, the carburetor was impact separated and damaged.
The wings, fuselage, vertical stabilizer, and rudder were substantially damaged. The leading edge of the wings exhibited crush damage and the rudder was bent to the left. A fuel sample was taken from the airplane and no debris or water was noted.
