Narrative:

The landing gear of the piper PA-30 collapsed upon landing. Upon gear extension while on a five (5) mile final; the green gear down light was observed. At the one (1) mile mark on the final approach I again observed the green gear down light. Once over the threshold I again observed the green gear down light and visually checked the nose gear via a mirror mounted on the left engine inboard cowling. Upon executing the landing in mildly rough air; the airplane touched down; bounced slightly; then settled softly back on the runway at which point the gear collapsed. Upon exiting the airplane; I briefly looked at the gear motor assembly beneath the floor between the front two seats and noticed that a portion of the airframe supporting the gear motor assembly appeared to have been torn away.
