Corroded, Cracked

The aft canted bulkhead (p/n 2612060-5) at station 474.40 was discovered with two cracks, each approximately 1.5 inches in length. During removal, other damage was found. Both vertical stabilizer webs (p/ns 2631021-15 and 2631022-2) were replaced because of significant fretting, as was the aft bulkhead assembly (p/n 2612059-1).
