What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot reports having a three green, down and locked landing condition. Witnesses on ground state that the aircraft landed with gear in the down position and was observed rolling out after landing. Pilot reports that gear began to collapse during rollout and the aircraft veered to the right off of the runway. Post-incident inspection found the landing gear control handle in the down position. All three gear assemblies were found to be in a state of mid-travel between full up and full down. Landing gear gearbox rotated freely when operated by hand. No pre-incident mechanical issues were noted.
