Cessna 150F Safety Record

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.

The partial loss of engine power due to carburetor icing and the pilot's inability to maintain 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 loss of engine power due to the mechanic's inadequate tightening of the crankshaft gear retaining bolts during an engine overhaul, which resulted in fatigue failure of the bolts and the crankshaft gear dowel pin that allowed the crankshaft gear to separate from the crankshaft.

The student pilot did not control the airplane’s pitch attitude, which resulted in an aerodynamic stall during the takeoff initial climb. Contributing to the accident was the pilot’s failure to use the pre-takeoff checklist.

The pilot's delay in using carburetor heat while operating in carburetor icing conditions, resulting in carburetor ice and subsequent partial loss of engine power.

A partial loss of engine power during initial climb due to fuel system contamination by a foreign substance. Contributing to the accident was the uneven terrain.

The pilot's improper decision to attempt a landing with an excessive tailwind, which resulted in an inadvertent stall while attempting to climb during a go-around. A factor related to the accident was the tailwind conditions and the rising terrain beyond the runway.

The loss of engine power due to carburetor ice as a result of the pilot's failure to apply carburetor heat. A contributing factor was the weather conducive to carburetor icing conditions.

The failure of the pilot-in-command (CFI) to adequately supervise the instructional flight. Factors in the accident were an inadvertent spin entry by the student, and the pilot-in-command's failure to utilize adequate altitude for a stall demonstration.

failure of the pilot to abort the takeoff after encountering excessive ground roll, and failure (or inability) of the pilot to obtain/maintain adequate airspeed, which resulted in an inadvertent stall. Factors relating to the accident were: restricted movement of the No. 4 cylinder exhaust valve, due to improper engine overhaul by the previous owner/mechanic, and failure of the current owner to perform maintenance after being advised by a pilot of excessive rpm drop during a carburetor heat check.

the pilot's impairment of judgment and performance due to alcohol which led to his failure to maintain sufficient altitude to clear surrounding terrain. A factor was the pilot's intentional buzzing.

Failure of the pilot to ensure that the other person (outside the airplane) remained clear of the operating propeller, and failure of the other person to maintain awareness of the hazardous condition. A factor relating to the accident was: the other person diverted his attention to spectators, who were standing nearby.

1) the pilot's decision to takeoff in an aircraft with a known, yet unresolved, engine performance deficiency, and 2) the pilot's failure to maintain an adequate airspeed while maneuvering back to the runway. A factor in the accident was the weld repair of the cylinder head rocker arm boss during overhaul, which led to a fatigue failure of the component.

THE STUDENT PILOT'S ALCOHOLIC IMPAIRMENT OF EFFICIENCY AND JUDGEMENT WHICH LED TO HIS GEOGRAPHICAL DISORIENTATION AND EVENTUAL FUEL EXHAUSTION AND TOTAL LOSS OF ENGINE POWER, AND HIS FAILURE TO MAINTAIN AIRSPEED DURING THE FORCED LANDING RESULTING IN A STALL/SPIN. A FACTOR WHICH CONTRIBUTED TO THE ACCIDENT WAS THE DARK NIGHT.
