## Discrepancy

SHORTLY AFTER DEPARTING,  DIVERTED BACK TO DEPARTURE DUE TO A RIGHT BLEED AIR FAIL WARNING.  THIS WAS A LIVE PART 135 FLIGHT, NO EMERGENCY WAS DECLARED, WHILE THE CREW LANDED SAFELY BACK AT AIRPORT.  IN TROUBLESHOOTING THE DISCREPANCY TECHNICIANS FOUND A PIN HOLE THE PLASTIC/EVA TUBING RUN ALONG THE RIGHT ENGINE NACELLE.  THIS SMALL PIN HOLE ALLOWED FOR ENOUGH AIR PRESSURE TO ESCAPE, CAUSING THE BLEED AIR WARNING SWITCH TO LOSE THE 2 PSI REQUIRED TO EXTINGUISH THE WARNING ANNUNCIATOR.  THE TUBING WAS REPLACED AND A SATISFACTORY OPERATIONAL CHECK OF THE BLEED AIR WARNING SYSTEM HAS BEEN COMPLETED.
