## Discrepancy

DURING MCK AT DEFORMATION WAS FOUND ON THE STA 560 FRAME UPPER CAP IN THE FWD CARGO COMPARTMENT.  ER/A 491629-14 SECT I WAS ACCOMP AT THAT TIME.  FOLLOW ON ACTION IS REQ FOR GAINING STAGE III APPROVAL FROM BOEING. STA MSP 25MAY11 ACCOMP ER/A 491629-14 SECTION II INSP PRIOR TO 20,000 TOTAL A/C CYCLES.  CONTACT ENGINEERING AT 18,800 TOTAL A/C CYCLES SO THAT ENG MAY CONTACT BOEING AND REQUEST STAGE III APPROVAL.
