Cessna P210N N44C accident near Pleasanton, Texas

Probable cause

Maintenance personnel's improper installation of the throttle linkage attachment hardware, which resulted in a partial loss of engine power when the hardware separated in flight.

NTSB analysis

The commercial pilot reported that, about 20 minutes into the cross-country flight, the engine suddenly experienced a partial loss of power. The pilot attempted to restore engine power but was not successful. During the subsequent forced landing to a road, the airplane struck a car, resulting in substantial damage to the fuselage and both wings. Examination of the airplane revealed that the hardware that attached the throttle linkage to the engine was not present. Given that the airplane had flown for only a few hours following recent maintenance, it is likely that maintenance personnel did not properly secure the throttle linkage hardware during that maintenance. No other anomalies were noted that would have precluded normal operations.
