Incident Overview
On April 18, 2015, at approximately 1135 central daylight time, a Grumman G-164A airplane, registration N7951, was substantially damaged during a forced landing near Maysville, Oklahoma. The commercial pilot, who was the sole occupant, sustained minor injuries. The aircraft was registered to a private individual and operated by Pro-Ag Service Inc. under 14 Code of Federal Regulations Part 137 as an aerial application flight. Visual meteorological conditions prevailed for the local flight, which operated without a flight plan. The flight departed from Pauls Valley Municipal Airport (PVJ), Pauls Valley, Oklahoma, at about 1030.
Sequence of Events
According to initial information obtained by the responding Federal Aviation Administration (FAA) inspector, the pilot had completed his second aerial application of the day and was returning to PVJ when the engine stopped producing power. The pilot executed a forced landing to a field. During the landing, the airplane nosed over, resulting in substantial damage to both wings and the vertical stabilizer.
Examination Findings
An examination of the airframe and engine by the FAA inspector did not find any anomalies that would have precluded normal operation. A review of the carburetor icing probability chart located in Special Airworthiness Information Bulletin CE-09-35 indicated that the airplane was operating in an area conducive only to serious icing at glide power.
