Narrative:
I was on a local pleasure flight in an experimental small aircraft. Upon entering the sql air traffic area I went through my landing checklist and extended the nose gear for landing. The handle slipped out of my hand and unwound several times. When the handle stopped, it felt as though the gear had fully extended and visually the gear appeared down and locked. Upon landing and lowering the nose, it became apparent that the nose gear had not fully extended and as weight increased on the gear, it collapsed. The aircraft slid to a stop on the runway with minor damage to the underside of the nose. There were no injuries. Other than cranking the gear 5 full turns from the up and locked position and visibility verification, there is no other gear unsafe warning in this aircraft.
