Probable cause
The failure of the right hydraulic main gear down-lock actuator hose in flight.
NTSB analysis
The pilot said that he lowered the landing gear in preparation for landing but did not see a “GEAR SAFE” green light. He visually confirmed that the right main landing gear had not extended fully and noted red fluid on the landing gear. The pilot landed on the left main landing gear and, as the airplane slowed, it settled on the right wing tip and came to a halt. A repair facility retrieved the airplane and reported that the right hydraulic main gear down-lock actuator hose had failed. The hose appeared to have been an original installation. Other hydraulic lines had been replaced as there were three different styles of hoses noted.
