The aircraft nosed over after the brakes locked during the landing roll. During the investigation, the FAA inspector and the operator of the aircraft found the parking brake in the 'ON' position. After the operator released the parking brake, the FAA inspector observed the wheels rotate freely.
On May 16, 1998, at 1130 central daylight time, a Grumman-Schweizer G-164B agricultural airplane, N6656K, owned and operated by King Flying Service, Inc. of Dumas, Arkansas, nosed over to the inverted position while landing near Dumas, Arkansas. The commercial pilot, sole occupant of the airplane, was not injured and the airplane was substantially damaged. Visual meteorological conditions prevailed for the local aerial application flight and a flight plan was not filed. The Title 14 CFR Part 137 flight departed the operator's private airstrip at 1100. During a personal interview conducted by the FAA inspector, the pilot reported that the brakes locked during the landing roll. The operator and the FAA inspector examined the airplane and found structural damage to the vertical stabilizer, rudder, and wings. The FAA inspector found that, "during the initial inspection of the aircraft the main landing wheels were found to be locked and could not be rotated." Upon examining the cockpit, the operator found the parking brake in the "ON" position. The operator then released the parking brake and had the FAA inspector check the main wheel rotation. Upon checking the brakes, the FAA inspector found the wheels to "rotate freely with no resistance." The pilot had accumulated approximately 2,061 hours in the accident make and model of aircraft and 12,394 total flight hours. Winds at the time of the accident were reported by the pilot to be light and variable.
The pilot's improper activation of the parking brake.
