Narrative:

I departed delivering an AC11 after maintenance on landing gear. Everything seemed normal. Approaching the pattern from the west I lowered the landing gear. I had initially not seen a green nose gear indication. While on the downwind I recycled the gear and got a positive indication 3 green and conducted a low approach requesting others on the ground to advise the status of the gear. Numerous responses were in the affirmative that it was down. I landed normally while coasting and decelerating; I gently applied brake pressure and felt the nose come down slightly; thinking the oleo strut must be settling after been serviced. I applied a tad more brake pressure and then the nose fell; the prop hit the ground and aircraft slid.the AC11 had just completed service on the oleo struts and oil change as far as I know. I was well rested.
