## Discrepancy

THE RADOME HAS BEEN PREVIOUSLY REPAIRED. THE PREVIOUS REPAIRS ARE NOT COMPLIANT WITH THE CURRENT CMM 53-11-15, REV 22 MAY 2011.1.24.  REPAIRS OF 130 MM DIAMETER AND 12 REPAIRS OF 50 MM DIAMETER HAVE BEEN PERFORMED ON THE SHELL SANDWICH AREA WITH HONEYCOMB REPLACEMENT AND A SINGLE REPAIR OF ALL THE INNNER SKIN EXCEPT THE MONOLITHIC AREA.  IF THE REPAIRS HAVE BEEN PERFORMED IAW TASK 53-15-11-300-801-A01, THE ANOMALIES ARE: THE 3 PRE-PREG LAYERS OVERLAP THE 3 ORIGINAL LAYERS WITHOUT THE 15 MM+/-3 REQUIRED STEPS; THERE IS NO ADHESIVE FILM AND AN UNKNOWN PRE-PREG HAS BEEN USED; THE SMALLER DISTANCE BETWEEN REPAIRS IS 10 MM INSTEAD OF 150 MM MAXI.  IF THE REPAIRS HAVE BEEN PERFORMED IAW TASK 53-15-11-300-808-A01,THE MAXIMAL REPAIR DIAMETER SHALL BE 500 MM WHEREAS THE REPAIR AREA IS ON ALL THE SHELL SANDWICH AREA.
