## Discrepancy

FLUORESCENT PENETRANT INSPECTION INDICATED CRACKS IN RT ENGINE FORWARD NACELLE NR 1 FRAME.  SUBMITTER STATED SEEMED TO BE A REPETITIVE DISCREPANCY AS PREVIOUSLY DETAILED AND REPORTED AND POSSIBLE CAUSE IS STILL UNDETERMINED.  WOULD SUSPECT ENGINE TORQUE AND VIBRATION AS POSSIBLE CONTRIBUTING FACTORS.  WOULD SUGGEST TIMED INTERVALS FOR REPETITIVE INSPECTION OF AREA.
