Accident Summary

On September 14, 2018, at about 1718 Pacific daylight time, a Cessna T210 airplane, registration N5340Y, was substantially damaged during the landing roll at San Luis Obispo County Regional Airport (SBP), San Luis Obispo, California. The private pilot, who was also the owner and operator, was not injured. The flight was conducted under Title 14 Code of Federal Regulations Part 91 as a personal cross-country trip. It originated from John Wayne-Orange County Airport (SNA), Santa Ana, California, at 1613 with SBP as the destination. Visual meteorological conditions prevailed, and no flight plan was filed.

Pilot Report

The pilot reported that during the approach to SBP, he selected the landing gear to the DOWN position and felt the gear extend into place. He observed the left main landing gear through the window and perceived everything as normal. As the airplane touched down at an estimated 65 to 70 knots, he felt a "bump up from the right" as the nose landing gear immediately contacted the runway. The airplane veered right, exited the runway, completed a 180-degree turn, and came to rest in the runway safety area. The pilot stated he did not hear the landing gear warning horn nor recall seeing the landing indicator lights during the approach. He was using a noise-cancelling headset.

Aircraft Information

The six-seat, high-wing, retractable tricycle-gear airplane, serial number 21064173, was manufactured in 1981. At the last annual inspection on March 22, 2018, the aircraft had accumulated 6,813.5 total airframe hours.

Examination Findings

Initial examination by a Federal Aviation Administration inspector revealed that the right main landing gear was retracted, and the right horizontal stabilizer and right elevator had impacted the ground and were buckled upward. After the airplane was moved to an airport facility, the landing gear extension motor was replaced. The landing gear was then tested, and no anomalies were noted; the warning horn sounded and landing gear indicator lights illuminated during testing. The original extension motor, which was the pump installed during manufacturing, was disassembled and found to exhibit internal wear.
