NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

On July 8, 2016, about 1604 Pacific daylight time, a Cessna 140, N89965, was substantially damaged when the left main landing gear collapsed during landing at Salinas Municipal Airport (SNS), Salinas, California. The pilot/owner and his passenger were uninjured. The personal flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed.

The pilot stated that he was on a cross country flight from Charles M Schulz - Sonoma County airport (STS), Santa Rosa, California, to his home airport of Paso Robles Municipal airport (PRB), and that the landing at SNS was a planned intermediate stop. The flight from STS was uneventful, as was the approach to, and initial touchdown on, runway 26 at SNS. The pilot stated that he made a normal three-point landing, and during rollout, the left wing dipped. He applied opposite aileron, but the airplane continued to roll to the left, and then the cabin floor beneath his legs deformed upward. The left wing and propeller struck the runway surface, and the airplane came to a stop on the runway shortly thereafter.

Post accident examination of the airplane revealed that the left main landing gear had rotated aft and up, and that the landing gear leg support structure ("box") formed by two transverse bulkheads had failed. The airplane was retained by the NTSB for additional examination.

According to the pilot, he had a total flight experience of about 177 hours, including about 38 hours in the accident airplane. He obtained his private pilot certificate in March 2015, and his tailwheel endorsement in January 2016. His most recent FAA third-class medical certificate was issued in July 2016.

FAA information indicated that the tailwheel airplane, serial number 9017, was manufactured in 1946, and was equipped with a Continental C-85 series engine. The airplane was registered to the pilot in January 2016. The pilot reported that the airplane had an approximate total time in service of 4,900 hours.

SNS runway 26 was asphalt, and measured 6,004 by 150 feet. The airport elevation was listed in the FAA database as 84.3 feet. At the time of the accident, the air traffic control tower was staffed and operating.

The 1553 SNS automated weather observation included winds from 280 degrees at 13 knots, visibility 10 miles, clear skies, temperature 18 degrees C, dew point 12 degrees C, and an altimeter setting of 30.02 inches of mercury.

The 1632 SNS special weather observation included winds from 280 degrees at 12 knots, visibility 10 miles, a broken cloud layer at 1,500 ft above ground level, with the same temperature, dew point, and altimeter setting as above.
