NTSB Narrative Summary Released at Completion of Accident
On February 28, 2014, about 0955 Pacific standard time, a Grumman G-164A Ag-Cat, N72ES, was substantially damaged during landing at a private agricultural airstrip in Fresno, California. The airplane was owned and operated by Trinkle Ag Flying, Kingsburg, California. The pilot was not injured. The aerial application flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 137. Visual meteorological conditions prevailed, and no FAA flight plan was filed for the flight.
The pilot was operating into, and out of, the private airstrip owned by Kenny's Cropdusting, Fresno. The airstrip was equipped with a 1,200-foot-long paved runway, but it was not assigned a Federal Aviation Administration (FAA) identifier. The terrain to the east side of the north-south runway was about 5 feet lower than the runway, and the two were separated by an embankment
According to the pilot, the flight was the third one of the day, and he was applying fertilizer. On touchdown to the north, the pilot heard a "huge bang," and the airplane began to roll right wing down. He tried to correct with aileron but was only partially successful. The airplane decelerated, veered to the right after the right wing contacted the ground, and departed the paved surface. As it began descending the embankment, the propeller struck the ground, and the airplane nosed over. The airplane came to rest inverted, partially down the embankment and mostly off the runway. There was no fire or fertilizer spill.
FAA information indicated that the airplane was manufactured in 1972, and was equipped with a Pratt & Whitney R-985 series engine. The airplane had a total time in service of approximately 16,800 hours. Photographs provided by the operator and an FAA inspector revealed that the right main landing gear leg had fractured near the upper bend, just below the fuselage. Preliminary examination of the fracture surfaces revealed characteristics similar to a fatigue fracture. The two sections of the fractured gear leg were sent to the NTSB Materials Laboratory in Washington, DC, for detailed examination and analysis.
The pilot held a commercial pilot certificate with an airplane single engine land rating. He reported that he had a total flight experience of approximately 2,437 hours, including about 1,943 hours in the accident airplane make and model.
The 0953 automated weather observation at Fresno Yosemite International Airport (FAT), Fresno, located about 15 miles north of the accident site, included winds from 130 degrees at 18 knots; visibility 10 miles; few clouds at 3,500 feet, scattered clouds at 15,000 feet, a broken cloud layer at 20,000 feet; temperature 17 degrees C; dew point 13 degrees C; and an altimeter setting of 29.55 inches of mercury.
