What was found
THIS IS ACTUALLY ON AN AIRBUS HELICOPTER H145D3 AIRCRAFT, BUT I WAS UNABLE TO FIND THE CORRECT MANUFACTURE LISTED FOR THIS. HYDRAULIC FLUID WAS LEAKING FROM THE CEILING IN THE BACK OF THE AIRCRAFT. FOUND A DRAIN LINE THAT HAD A HOLE IN IT FROM RUBBING ON A RIVET. THERE WAS NO FLUID LOSS FROM THE SYSTEM. THE FLUID WAS FROM A FLUID AND FILTER CHANGE COMPLETED THAT ALLOWED SOME RESIDUAL FLUID TO ENTER THE DRAIN SYSTEM.
