Golden Sierra Aviation

Cessna 421B Golden Eagle II

The pilot said he was on the takeoff ground roll at about 100 knots when he discovered that the control lock was still in place. The pilot said he attempted to remove the control lock but could not prior to the aircraft over running the departure end of the 3,400 foot long runway. The aircraft collided with a county sewage treatment building, separating the wings from the fuselage. The aircraft fuselage continued through the building and came to rest on rocks near the beach. All four occupants were seriously injured.
