How do I properly execute a trigger using cursor query

Please find attached table structure and the trigger developed to update the stage table (s_ais) when changes occur to the underlying table, ais.  As we are only interested in a subset of records found in the ais table, I attempted to use a cursor to filter only on ais that are of interest to CDT.  

My trigger is failing, ORA-06502; numeric or value error: char string buffer too small on line 40.  Yet I fail to see the necessary action to be taken.  I assume the cause is that I am trying to execute a statement that resulted in an arithmetic, numeric, string, conversion, or constraint error.

If I run the cursor solo, the resultant is as expected.  A proper list of ais displays.

Any assistance is appreciated.
