Cessna 172 Safety Record

A partial loss of engine power for reasons that could not be determined, and the flight instructor's exceedance of the airplane's critical angle of attack while maneuvering for a forced landing, which resulted in an aerodynamic stall and subsequent loss of control.

The pilot’s decision to depart into marginal visual flight rule conditions in mountainous terrain with the potential for icing, and the airplane’s accumulation of structural icing, which resulted in the pilot’s inability to maintain airplane control and the subsequent aerodynamic stall and spin into terrain.

The flight instructor's failure to maintain airplane control during initial climb after a touch-and-go landing, which resulted in an exceedance of the airplane's critical angle of attack and an aerodynamic stall.

The pilot's inadequate and/or improper preparation for the flight in which he selected an altitude too low to assure terrain clearance and resulted in an impact with terrain in turbulent downdraft conditions.

The pilot's inadequate maintenance of the airplane, which resulted in a total loss of engine power due to fuel starvation when organic debris restricted available fuel to the carburetor, and the pilot's impairment due to the ingestion of alcohol, which affected his ability to safely operate the airplane following the loss of engine power.

An in-flight breakup as a result of the airplane exceeding the structural strength of the airplane during a rapid descent that the flight instructor was unable to recover from following a collision with a large bird.

The student pilot's failure to retract the flaps following landing and the stall/mush that resulted during the subsequent full-flap takeoff and initial climb.

The pilot's flight in dark night visual meteorological conditions, which resulted in an impact with water for reasons that could not be determined based on the available information.

The pilot's failure to maintain clearance from the water while flying over a lake with glassy surface conditions. Contributing to the accident was the pilot's use of three impairing medications.

The pilot's decision to continue visual flight into instrument meteorological conditions, which resulted in a loss of control due to spatial disorientation.

The pilot's failure to maintain airspeed during the initial climb after takeoff, which resulted in the airplane exceeding its critical angle of attack and a subsequent aerodynamic stall/spin.

The pilot's decision to fly along the river at a low altitude contrary to applicable regulations and safety of flight considerations which resulted in the impact with the power lines. Contributing to the accident was the pilot's inability to see the and avoid the power lines due to their proximity to a bend in the river and the position of the sun at the time of the accident.

The pilot's decision to fly into a canyon during wind conditions conducive to turbulence and downdrafts, and his subsequent loss of aircraft control while maneuvering in the canyon. Contributing to the accident was the pilot's limited canyon flying experience.
