Plain English Summary

4/10 complexity

This Airworthiness Directive requires operators of all Boeing 727-series aeroplanes to carry out the inspections and corrective actions specified in FAA AD 2005-20-13 and the referenced Boeing Alert Service Bulletin to find and fix cracks in lower lobe frames at body section 43. Compliance is mandatory from 22 December 2005. It matters because reported cracks at tooling holes can grow into skin panels and create a risk of rapid decompression, so operators must inspect and repair affected structure to remain airworthy.
