Probable cause

Fatigue failure of the throttle cable. Factors related to the accident were: darkness and objects (fence and utility poles) in the emergency landing area.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The plt rprtd that during a flare to land, he noted a 'click' as he moved the throttle to the idle position & there was no reduction in eng power. He stated the throttle seemed very loose & did not appear to be connected to the eng. The eng went to full power & the turbocharger overboost light illuminated. With an airspeed of 120 KTS, he aborted the landing. As he attempted to maneuver the acft to land, the eng power went to a mid-power range, then surged to a higher range. The plt was forced to make an off-arpt landing. Subsequently, the acft collided with a fence & light poles, then a fire erupted & the plane was desroyed. An exam revealed the throttle cable had failed from high cycle fatigue, which resulted in the uncontrolled eng condition.
