What was found
NUMEROUS IN FLIGHT L OR R BLEED LEAK CAS MESSAGES OVER THE PAST TWO YEARS. NOT ABLE TO REPRODUCE THEM ON THE GROUND OR DURING MAINT CHECK FLIGHTS. EVEN GETTING THIS WITH THE THROTTLES PULLED BACK AND NOT WHEN THERE IS POWER APPLIED. WE DO NOT FIND LEAKS DURING THE CHECKS. THE INDICATIONS ARE RANDOM AND HAPPEN IN ALL PHASES OF FLIGHT (CLIMB, CRUISE, DECENT, LANDING). RESEARCHING OUR FLEET OF 45'S TO DETERMINE IF ANY SB STATUS MAY HELP AS THIS IS AN ISSUE ACROSS OUR FLEET. STILL INVESTIGATING THE CAUSE AND WANTING TO DOCUMENT THIS FOR OTHERS. WILL CREATE ADDITIONAL SDR'S AS WE GET MORE ISSUES TO UPDATE.
