Accident Overview
On May 29, 2018, at approximately 0900 Pacific daylight time, a Cessna P210, registration N7546K, sustained substantial damage during a gear-up landing near Lewiston, Idaho. The private pilot, who was the sole occupant, was not injured. The flight was conducted under Title 14 Code of Federal Regulations Part 91 as a personal trip.
Sequence of Events
According to the pilot, after departure he climbed to his planned enroute altitude of 7,500 feet mean sea level. He observed that the airspeed was lower than expected and subsequently noticed that the landing gear position indicator light indicated the gear had not retracted. The pilot cycled the landing gear but could neither fully extend nor retract the gear. He then attempted to manually lower the landing gear using the emergency hand pump, which was also unsuccessful. After declaring an emergency, the pilot landed the airplane with the gear retracted. The horizontal stabilizer spar was substantially damaged during the landing.
Examination Findings
Post-accident examination revealed that the rigid hydraulic line connecting the powerpack to the bulkhead had failed at the ferrule.
Maintenance History
A review of the airplane's maintenance records showed that on March 13, 2018, at a tachometer time of 384 hours, a maintenance facility completed a landing gear check. A subsequent entry, dated May 17, 2018, and logged about 8.6 flight hours later, stated: "Landing gear inop for up/dn. Pilot report did pump gear down." The entry indicated that maintenance personnel performed troubleshooting on the source of a hydraulic fluid leak, which they determined to be at the hydraulic power pack gear system. The entry further stated that the tube fitting line had cracked at the flare below the ferrule, and a new line of aluminum tubing of the same size and length as the failed tubing was fabricated and installed.
