## Discrepancy

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