Probable cause

The improper maintenance work by an unknown person who crossthreaded a fuel nozzle injector fitting which allowed fuel to leak on the exhaust system initiating a fire. No reason for the right engine not to develop full power was found.

Analysis

The pilot stated that while in level flight the left engine failed and he observed a fire warning light and shut the engine down, the right engine then began to run rough and lose power. He then restarted the left engine but neither developed enough power to sustain flight. He executed a forced landing on a highway and struck a vehicle and a fire erupted. Examination of the left engine revealed a crossthreaded fuel nozzle fitting and soot patterns aft of it. No cause for the right engine failure was found. No evidence of an annual inspection was found.
