Introduction
A wheel/ski-equipped airplane experienced a left main landing gear collapse shortly after landing. The pilot reported that the gear failed about two seconds after touchdown at the upper attaching point.
Details
The incident involved an airplane equipped with wheel/skis. The pilot stated that the left main landing gear collapsed at the upper attaching point approximately two seconds after touchdown. Post-accident examination of the left outboard landing gear support, identified by Cessna part number 0713495 64, revealed that it had failed due to preexisting cracks.
Findings
According to the operator, the airplane and the failed support had accumulated a total of 4,520 hours. The majority of this time was logged while operating on rough terrain with wheel/skis installed. The preexisting cracks in the support were determined to be the reason for the failure.
