## Discrepancy

(CAN) WHILE ON FINAL APPROACH TO A WELL SITE, THE PILOT HEARD A LOUD BANG FOLLOWED BY A SEVERE AIRFRAME VIBRATION.  AN AUTOROTATION WAS INITIATED AND A NORMAL LANDING ENSUED WITH NO FURTHER INCIDENT.  THE ACFT WAS INSPECTED BY MX PERSONNEL BUT NO APPARENT DEFECTS WERE FOUND.  THE ACFT REMAINS AT THE WELL SITE PENDING FURTHER INVESTIGATION.
