Cessna 402/402C/B379 Businessliner/Utiliner
Aircraft Equipment Problem Critical
Flight Crew Returned To Gate
Aircraft
As I was taxing out from the gate to the runway; suddenly the right engine propeller feathered at 900 RPM. As I was with full passenger and bags load; I was unable to taxi back to the gate. I coordinated with Ground Control and the Company Maintenance and the ramp people. The passengers were transported from the plane back to the gate and the airplane was towed to the maintenance hangar. I was assigned another airplane and continued the flight.
For an unknown reason; the pilot of a Cessna 402 experienced an uncommanded autofeather of the propeller during taxi out. He was unable to taxi; so the passengers were transported to the gate and the aircraft was towed to the hangar.
