2008 Beech King Air 90 FL Maintenance Flight Non-Fatal Non-Fatal Multi-Engine Titusville

King Air 90 Non-Fatal Titusville, FL May 6, 2008

The pilot was landing the twin-engine, turboprop airplane on a 3,000-foot-long, 70-foot-wide, asphalt runway, when he encountered a high sink rate. He applied engine power; however, the engines did not respond quickly enough to prevent a hard landing. During the hard landing, the main landing gear separated and the left landing gear struck the vertical stabilizer. The pilot subsequently performed a go-around and landed on a grass runway, without further incident. The pilot stated that he did not experience any mechanical malfunctions. He reported 5000 hours of total flight experience, which included 500 hours in the same make and model as the accident airplane.
