## Discrepancy

DURING BASIC CHECK IN BNA, CRACK DAMAGE WAS FOUND IN TWO LOCATIONS NEAR THE UPPER AND LOWER CORNERS OF THE RH APU FIREWALL REMOVABLE PANEL (P/N 170-50263-401) ON AIRCRAFT N208AN. REFERENCE FIGURE 1 FOR DAMAGE/REPAIR LOCATIONS AND DETAILS. BOTH LOCATIONS WERE PERMANENTLY REPAIRED BY TRIMMING OUT THE CRACKED MATERIAL IN ACCORDANCE WITH THE TYPE V REPAIR FROM SRM PART II 53-31-21/REPAIR 02. THE PANEL IS NOT FCS, BUT IT REQUIRES SUPPLEMENTAL FOLLOW-ON DETAILED VISUAL INSPECTIONS PER SRM PART II 53-31-21/REPAIR 02. EA E175-53-1162.1 WILL BE ISSUED TO ACCOMPLISH THE SUPPLEMENTAL FOLLOW-ON INSPECTIONS OF THE REPAIR EVERY 10,000FC. COMPASS ENGINEERING HAS CLASSIFIED THIS AS A MINOR REPAIR. WORK ORDER 2819309444
