Probable cause
The NTSB’s determination of the probable cause, and any contributing factors.
The collapse of the left main landing gear during the landing roll due to preexisting cracks.
Analysis
The pilot stated that about 2 seconds after he touched down with the wheel/ski equipped airplane, the left main landing gear collapsed at the upper attaching point. Examination of the left outboard landing gear support (Cessna part number 0713495 64) found that it had failed due to preexisting cracks. The operator reported that most of the 4,520 hours on the airplane and the failed support were accumulated with the airplane operating on rough terrain with wheel/skis installed.
