## Discrepancy

MAINTENANCE DISCOVERED AN EXISTING REPAIR TO THE INNER SKIN OF THE FORWARD CARGO DOOR AT A LIGHTENING HOLE LOCATION.  THE EXISTING REPAIR WAS NOT INSTALLED PER CURRENT FAA REQUIREMENTS.  PREVIOUS ECRA 5232-01031 REPAIRED A LARGER AMOUNT OF DAMAGE TO THE SAME AREA AS THE CURRENT DAMAGE USING A DOUBLER INSTALLATION.  A REPAIR DOUBLER WAS INSTALLED AS A PERMANENT REPAIR TO THE INNER SKIN IAW ECRA 5232-01036.
