## Discrepancy

ELECTRICAL ARCING IN R-1 WINDOW CAUSED A SMALL AMOUNT OF SMOKE IN THE COCKPIT DURING CLIMBOUT OF GUM.  THE AIRCRAFT WAS RETURNED TO GUM WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND POWER WIRE TO R-1 WINDOW BROKEN AND BURNT.  THE WIRE WAS REMOVED AND WIRING WAS RESPLICED.  AN OPERATIONAL CHECK OF R-1 WINDOW WAS GOOD.
