Plain English Summary

3/10 complexity

This CASA Airworthiness Directive mandates inspection and repair of the S-6 lap splice fuselage skin on specified older Boeing 747 models to address cracking around fastener holes. It targets operators of 747-100/100B, 747-200 variants, 747-300, 747SR and 747SP in Australia.

The work must follow FAA AD 2008-10-15 and Boeing Alert Service Bulletin 747-53A2748 to prevent rapid decompression and possible structural failure; compliance was required by 31 July 2008.
