WPR15LA160

Just after takeoff on the agricultural application flight, the commercial pilot was positioning the airplane to spray a rice field. About 200 ft above ground level, the pilot heard a loud pop, and the engine experienced a total loss of power. The pilot turned the airplane to land on a dirt road, but it was too narrow; the right main landing gear contacted mud on the side of the road, and the airplane subsequently nosed over and came to rest inverted. Recovery personnel reported no residual fuel on the ground around the accident site, and about one half gallon of fuel was recovered from the airplane. The pilot stated that the airplane had not been refueled on the day of the accident and that he departed on the flight with less than a half tank of fuel. The postaccident engine examination revealed no mechanical anomalies that would have precluded normal operation. The loss of engine power was likely due to fuel exhaustion, and given that the loss of power occurred just after takeoff, it is likely that the pilot did not verify the amount of fuel onboard before departing on the flight.

On May 13, 2015, about 0930 Pacific daylight time, a restricted category Grumman Aircraft ENG COR-Schweizer G164A airplane, N8875H, experienced a loss of engine power shortly after takeoff, and the pilot subsequently made an emergency landing on a dirt road near Maxwell, California. Richter Aviation Inc., operated the airplane under the provisions of 14 Code of Federal Regulations Part 137 as an aerial application flight. The commercial pilot, the sole occupant, was not injured. The airplane sustained substantial damage. Visual meteorological conditions prevailed for the local flight that departed from a private airstrip. No flight plan had been filed. In the pilot's written statement, he reported that the airplane seemed to function normally; good magneto check before takeoff and no indications of any problems. About 200 feet above the ground he heard a loud pop, and then the engine quit. He made a right 90o turn to land on a dirt road. The road was too narrow, and the right wheel went over the edge into the rice field and got stuck in mud, which caused the airplane to slow down and flip over onto its back. During an interview with an inspector from the Federal Aviation Administration (FAA), the pilot reported that when he took off, on the day of the accident, there was less than half a tank of fuel on board. The operator reported that the day before, the left magneto had been replaced, and that the airplane had not been refueled following the maintenance. The operator also stated that the pilot started flying at 0900 the day of the accident for the purpose of spraying a pesticide on the rice fields. According to a responding deputy from the Colusa County Sheriff's Department, there was no evidence of fuel, or the smell of fuel, at the accident site. An FAA inspector reported that during the recovery of the airplane, maintenance personnel recovered ½ gallon of fuel out of the airplane. Maintenance personnel stated that there was no fuel smell, or residual fuel found on the ground. The airplane holds 80 gallons of fuel and burns about 40 gallons of fuel per hour. The loader reported that on the day of the accident the airplane was not refueled. During the postaccident engine examination, the FAA inspector stated that the engine turned freely without any binding, and about a 1/3-cup of fuel was recovered from the gascolator. Compression was obtained in all the cylinders except the #1 cylinder which had sustained impact damage. The left magneto produced a spark when rotated however, the right magneto had sustained impact damage and could not be functionally tested.
