What was found
FLYING FROM KDAL TO KLAX WITH PASSENGERS WHEN THE CAPTAIN NOTICED THE LH ENGINE LOW HYD PRESSURE LIGHT ILLUMINATING INTERMITTENTLY. HE CALLED IN TO JETVIA MAINTENANCE FOR GUIDANCE. THE AIRCRAFT WAS NEAR THE ELP AREA SO HE WAS INSTRUCTED TO DIVERT INTO ELP IN CASE HE WAS EXPERIENCING A HYDRAULIC PRESSURE/FLUID LOSS. THE AIRCRAFT LANDED SAFELY IN ELP. JETVIA MAINTENANCE MET THE AIRCRAFT AND DETERMINED THERE WAS NOT A LEAK IN THE HYDRAULIC SYSTEM. THE MAIN SYSTEM HYDRAULIC PRESSURE AND RETURN FILTERS WERE REMOVED AND INSPECTED FOR ANY SIGNS OF CONTAMINATION - BOTH FILTERS FOUND TO BE CLEAN. AFTER FURTHER EVALUATION, THE LH ENGINE HYDRAULIC PRESSURE SWITCH WAS DETERMINED TO BE FAULTY. A REPLACEMENT SWITCH WAS INSTALLED, ENGINE RUNS PERFORMED WITH NO ISSUES NOTED. THE AIRCRAFT WAS REPOSITIONED TO KCLT FOR OTHER MAINTENANCE WITH NO ISSUES REPORTED.
