## Probable cause

the partial loss of engine power due to the separation of the number 5 cylinder fuel injector supply line.  The fuel line separation was due to company maintenance personnel's failure to secure the b-nut fitting following maintenance.  Factors in the accident were the unsuitable nature of the terrain where the engine problem developed and the pilot's failure to maintain airspeed while attempting to reach a suitable forced landing spot, which led to an inadvertent stall.
