Narrative:

I went to do a couple takeoffs and lndgs. After the initial preflight walkaround; I started the engines; announced on CTAF taxiing for takeoff on runway 16. At the hold point on runway 16; I did the pre takeoff run-up; announced my intentions; and took the runway. After clearing the runway; the gear was raised and I turned left crosswind to runway 16; followed by the downwind leg. Abeam the threshold of runway 16; I lowered 20 degrees of flaps; did the gump check lowering the gear; and called for left base 16. After announcing final to full stop; I lined up with runway 16 and lowered to full flaps; again performing the gump check. Just past the numbers; I made a smooth landing; rolled approximately 1000 ft; and as I approached the intersection of runway 16 and runway 20; I raised the flaps and began to apply braking. Suddenly; the nose started down and the propellers began striking the asphalt. Within a couple of seconds; the aircraft headed left; off the runway; where I came to rest in the grass facing the opposite direction. The right main was down and locked; the left main had folded to about 20 degrees; and the nose gear was folded into its bay. Immediately; I turned off the magnetos; alternators and battery switches; exited the aircraft; and called for assistance. There was no fire; and no injuries. The following morning; the aircraft was recovered by a local a&P; whose tem raised the aircraft by the left engine mounts and managed to get the left main and nose gear down.
