What was found

CRACKS FOUND DURING INSPECTION. CRACKS FOUND IN LOWER RELIEF EDGE MADE USE OF REPAIR KIT P/N: 767 - 397 NOT POSSIBLE. THE CRACK REQUIRED REPLACEMENT OF ENTIRE RIB ASSY WITH NEW PART 78475-004 (AN IMPROVED PART). HAVE DIGITAL PHOTOS OF THE CRACKED RIB, THE CRACKS ARE CAUSED BY FLEXING OF THE SPAR BY THE LANDING GEAR SIDE BRACE DUE TO SIDE LOADS DURING LANDING. IF NO REPLACED I DON'T SEE AN INFLIGHT FAILURE, BUT COULD SEE POSSIBILITY OF LANDING GEAR COLLAPSE.
