What made the gear collapse?

[pelmet]

C-FBPO, a privately operated Beech A24R aircraft, was flying circuits on Runway 31 at Quesnel,
BC (CYQZ). While on the downwind leg of the last circuit, the pilot selected the landing gear down
and confirmed its position with three landing gear lights. Upon touchdown, all three landing gear
legs partially collapsed. The aircraft remained on the runway and incurred a propeller strike as it
skidded to a stop. The pilot reported the incident to Williams Lake radio on the MF. Emergency
response vehicles were dispatched. There were no injuries to the pilot who was the only occupant.
The aircraft received minor damage.
