What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
According to the pilot, "on 12/15/2018 at approximately at 1155 mountain standard time (MST) a Froelich Robert E. Lancair IV was returning from flight and lined up on runway 35 at around 80 KIAS. Touchdown was normal and smooth, but when I lowered the nose to the runway I felt the nose gear touch followed by it continuing to collapse with parts of the shattering prop scattered about as we slid to a stop. Two personnel were on board with no injuries." No mechanical failure could be identified.
