## Discrepancy

RIGHT OUTBOARD FLAP ACTUATOR CRACKED AT BASE OF PISTON WHERE THE END PLUG IS ATTACHED.  THE CRACK WAS 1.5 INCHES LONG AND RESULTED IN THE LOSS OF THE LUBRICATING OIL FROM OUT OF THE PISTON AND SCREW ASSEMBLY.  THE LOSS OF OIL WAS THE FIRST INDICATION OF A PROBLEM, AND IT WAS WHILE INVESTIGATING THE OIL LEAK THAT THE CRACK WAS DISCOVERED.THIS CRACK COULD RESULT IN A SIGNIFICANT LOSS OF STRUCTURAL STRENGTH OF THE ACTUATOR WHICH COULD RESULT IN THE STRUCTURAL FAILURE OF THE ACTUATOR ASSEMBLY.
