aviation accidents

Probable cause: The pilot’s improper preflight planning that did not identify the unserviceable runway; his subsequent decision to attempt to takeoff from the rough, grassy runway; and his selection of an abort point with insufficient runway remaining, which resulted in a runway overrun.

Probable cause: A loss of engine power due to carburetor icing, the pilot’s decision to turn back to the runway shortly after takeoff, and his failure to maintain airspeed during the turn, which resulted in an exceedance of the airplane’s critical angle of attack, and subsequent aerodynamic stall.

Probable cause: The loss of engine power due to fuel starvation.

Probable cause: A total loss of engine power as a result of the detachment of the throttle linkage from the throttle arm of the fuel injector servo due to an insufficiently tightened and secured bolt and the subsequent inadequate maintenance inspection.

Probable cause: The pilot’s failure to use carburetor heat during a low-power setting approach in conditions conducive to carburetor icing, which resulted in a partial loss of engine power.

Probable cause: The pilot’s failure to maintain clearance from tree foliage on the left side of the runway during takeoff due to his focus on the right side of the runway.

Probable cause: A stuck No. 3 cylinder exhaust valve, which resulted in failure of the associated rocker arm, a partial loss of engine power, and the subsequent forced landing into tall vegetation.

Probable cause: The loss of two securing bolts that allowed the left magneto to move around, which disrupted the spark timing and resulted in the engine losing total power.

Probable cause: The pilot’s decision to depart with an inoperative left magneto, which resulted in degraded climb performance in high-density altitude conditions and a subsequent emergency landing.
