Analysis

The acft rolled over after a forced lndg due to loss of power. The eng lost about 60 percent of its power during cruise at about 250 ft AGL. Post acc inspection showed that fuel line p/n 685481 b-nut had backed off the fuel control end of line 250C20 ipc. The last major eng maintenance was a turbine change on 3/3/85. The last heavy inspection was on 10-11-85. The acft flew 47.5 hrs after that inspection before this fuel line disconnection.
