Acft eng quit, pilot made emerg landing in a field. Acft struck a tree. Midlothian, TX (.4)the aircraft was descending from 8,500 feet, when the pilot 'felt the airplane shutter and begin to sound slightly rough.' The pilot observed that the manifold pressure had dropped 'slightly,' and the fuel flow gauge dropped from '21 to 10 gph.' The pilot maintained a 'slow' descent, turned the boost pump on, and switched to a different fuel tank. There was an increase in engine manifold pressure, and the fuel flow increased to 15 gph. Smoke entered the cockpit as the airplane descended through 2,500 feet, and the pilot 'noticed flames coming from the engine cowling vents.' The pilot initiated a forced landing to a grass field. During the landing roll, the left wing struck a tree, and the airplane went through two fences, crossed a road, then came to rest in a plowed field. Examination of the engine revealed that the #2 cylinder fuel injector line had broken, and 'sprayed fuel onto the turbocharger.' Examination of the fuel injector line revealed that the separation was the result of fatigue cracking which initiated from a dam aged area on the fuel line. Airworthiness directive 93-02-05 (which required on inspection of the fuel injector fuel lines) was complied with 39 flight hours before the accident. (-23) see attached. No narrative attached.
