Analysis

While en route at 8000', the eng lost power & the plt obtained vectors for an emerg landing at an arpt with a grass strip. Drg the roll-out, the left wing tip hit a hay wagon near the end of the rwy, then the acft veered & struck a hangar. An exam of the throttle linkage revealed that a swivel joint had broken off of the throttle arm attaching bolt, which allowed the fuel injector to vibrate to idle. The failure occurred where the shank area of the attaching bolt had been rubbing against the attached throttle cable fitting & had become worn.
