Narrative:

Landing; on 3 green lights no red normal straight in landing. No indications of any abnormalities. Landed on 1000 ft markers and rolled approximately 500 ft when the nose began to settle with the tire on the runway. The gear on the front was apparently not down and locked and it collapsed. I immediately shut down and secured the aircraft and called the FAA.
