Narrative:

Upon landing at npa, the gear was checked down on the T28B on downwind and final and all gear showed down and locked. From the ground, some of the spectators said they noticed the nose gear appeared not down. As I touched down, the nose gear collapsed and I slid on the nose for approximately 900 ft, causing major damage to the propeller and engine with minor damage to any sheet metal. No personal injuries. Possibly the tower could have prevented the incident by noticing the nose gear not down and waved me off and given me the opportunity to assess the situation, possibly allowing the nose gear to lock down. Callback conversation with reporter revealed the following information: the reporter stated there was no indication the nose gear was not down and locked. The reporter said the handle light, mechanical indicator all were normal and the warning horn was silent. The reporter said the aircraft has not been jacked to determine the cause of the gear failure.
