## Discrepancy

THE OVER LIMIT LIGHT ILLUMINATED ON LANDING.  ACCORDING TO PILOT, WAS ON ROUTE, 1 MILE OUT, IN SEMI-WINDY CONDITIONS. DID NOT PUT ACFT IN ANY ABRUPT MOVEMENTS TO CAUSE OVERSPEED CONDITION & NEVER EXPERIENCED A GONG IN HEADSET.  AFTER LANDING, AT SHUTDOWN,  VEMD SHOWED AN OVER LIMIT.  FURTHER INVESTIGATION REVEALED AN NG OF 431 RPM, IAW AMM 05-50-00 6-3, OVER 430 RPM NEEDS TO BE INSPECTED.  INSPECTED IAW MM, AND RETURNED TO SERVICE, NOTHING NOTED .  PERFORMED A MAINTENANCE TEST FLIGHT TO SIMULATE AND OVERSPEED,  REACHING 424 RPM, EXPERIENCE A GONG IN HEADSET, BUT NO LIGHT ILLUMINATED ON VEMD AT SHUTDOWN.
