## Discrepancy

HELICOPTER USED IN LOGGING OPERATION.  DURING DAILY INSPECTION, SHEET METAL CRACK ABOUT 3 INCHES IN LENGTH WAS DISCOVERED ON THE STRUCTURAL SUPPORT FOR THE LEFT FORWARD TRANSMISSION MOUNT PAD.  THE CRACK IS RADIATING OUTWARD FROM A RIVET. SUSPECT CAUSE, IMPROPER RIVETING PRACTICE.  KNOWLEDGE AND USE OF RIVET METHOD AND TECHNIQUE WOULD PREVENT RECURRENCE.
