Accident Details
On July 19, 2012, about 1900 mountain daylight time, a Cessna T210M, registration N311TM, experienced a landing gear malfunction during approach to City of Colorado Springs Municipal Airport (KCOS), Colorado. The airplane was operated by Aerworthy Consulting, LLC, of Franktown, Colorado, as a personal flight under 14 CFR Part 91. Visual meteorological conditions prevailed, and an instrument flight rules flight plan had been filed. The flight originated from Liberal Municipal Airport (KLBL), Kansas, at 1621.
Pilot Actions
The pilot reported lowering the landing gear in preparation for landing but did not receive the gear-safe green light. He visually confirmed that the right main landing gear had not fully extended. Red fluid was observed on the landing gear. A low pass was made, and control tower personnel confirmed the gear was not fully extended. The pilot attempted to manually extend the gear without success. After burning off most of the fuel from the right tank, the pilot performed a landing on the left main landing gear. As the airplane slowed, it settled onto the right wing tip and came to a stop.
Post-Accident Examination
Examination after the accident revealed that the right elevator and horizontal stabilizer spar had been broken. The pilot stated that the last annual inspection was conducted on February 2, 2012, at a total time of 3,146 hours, during which some but not all hydraulic lines were replaced. Beegles Aircraft Service transported the airplane to their facility in Greeley, Colorado, for repair. They identified that the right-hand hydraulic main gear down lock actuator hose had failed. This hose appeared to be an original installation. The remaining hydraulic lines had been replaced with three different styles of hoses.
