Key Takeaways:

An Airbus medical helicopter crashed near Sacramento in October after the flight paramedic reported an "uncommanded loss of power" shortly after takeoff from UC Davis Medical Center.
The helicopter climbed to approximately 500 feet before an 11-second descent, landing hard on U.S. Route 50, where it sustained substantial damage.
A critically injured flight nurse died four days after the crash, and the NTSB's preliminary report confirms an ongoing investigation into the incident.
