Cessna Safety Record

The stuck turbocharger wastegate in the closed position for reasons that could not be determined based on the available information. Also causal was the pilot's failure to reduce the throttle during takeoff when the manifold pressure and fuel flow exceeded the takeoff limitations and the pilot's decision to turn on the fuel boost pump, which exacerbated the excessively rich fuel mixture and resulted in a total loss of engine power.

Wear of the No. 4 cylinder exhaust camshaft lobe and roller tappet, which resulted in the failure of the tappet and the subsequent total loss of engine power.

The pilot's improper flap setting for takeoff and subsequent exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall. Contributing was the overgross state of the airplane.

The pilot’s inadvertent encounter with downdraft conditions, which resulted in a loss of altitude, and the pilot’s subsequent decision to conduct a precautionary landing into a stand of trees.

The pilot’s failure to maintain lateral control and his subsequent failure to maintain the runway heading during an attempted go-around, which resulted in impact with trees.

The pilot’s failure to maintain terrain clearance after an encounter with a downdraft while maneuvering in a valley with a high-density altitude, which resulted in impact with trees and terrain.

The pilot's failure to properly set the elevator trim before takeoff, which resulted in an exceedance of the airplane's critical angle of attack during takeoff and a subsequent aerodynamic stall. Contributing to the accident was the pilot’s failure to follow the Before Takeoff—Run Up checklist.

The student pilot’s impairment by alcohol and multiple medications, which led to his failure to maintain obstacle clearance during takeoff and the subsequent exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall and impact with terrain.

The pilot's failure to apply carburetor heat in conditions conducive to the accumulation of carburetor icing, which resulted in a total loss of engine power.

Maintenance personnel's failure to properly apply torque to the engine through bolts, which ultimately resulted in the crankshaft failure and the total loss of engine power.

The pilot's failure to attain adequate airspeed during the soft field takeoff, which resulted in an exceedance of the airplane's critical angle of attack and an aerodynamic stall.

The non-instrument-rated pilot’s loss of control during an encounter with instrument meteorological conditions at night. Contributing to the accident was the pilot's decision to depart on the flight without obtaining approval to fly at night in accordance with company policy.

The pilot's delayed decision to execute an emergency landing and his attempt to return to the airport following a partial loss of power due to wear on internal engine components, which prevented the engine from developing full-rated power during the airplane's initial climb.

The pilot's improper in-flight fuel management and reliance on a faulty fuel gauge, which resulted in fuel starvation during approach for landing, and his failure to follow the emergency checklist after losing engine power.

The pilot's decision to take off in high-density altitude and gusting quartering tailwind conditions, which resulted in a loss of lift and an inability to gain altitude during the initial climb.

The pilot's failure to use carburetor heat while operating in weather conditions that were conducive to carburetor ice formation, which resulted in a total loss of engine power due to carburetor ice accumulation.
