## Discrepancy

SHORTLY AFTER TAKEOFF THE RIGHT ENGINE FIRE WARNING ILLUMINATED.  POWER WAS REDUCED TO THE RIGHT ENGINE AND THE WARNING LIGHT EXTINGUISHED.  A PRECAUTIONARY LANDING WAS MADE AT THE DEPARTURE AIRPORT.  INVESTIGATION REVEALED THE RIGHT GENERATOR EXPERIENCED A CATASTROPHIC FAILURE.  THE FIRE SENSING ELEMENT IS ROUTED OVER THE GENERATOR AND WAS THE CAUSE IF THE FIRE INDICATION.  PRELIMINARY INSPECTION REVEALED POSSIBLE BEARING FAILURE WITHIN THE GENERATOR.
