What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The nose gear collapsed on roll out following a normal landing when the propellers were placed in reverse pitch. The aircraft came to a stop on the center of the runway after sliding on the nose gear doors. Post incident inspection has not revealed any physical reason for the nose gear collapsing. Retraction and extension tests are normal. Aircraft testing and inspection will continue by local maintenance facility.
