Plain English Summary

5/10 complexity

Requires all Model 727 operators to carry out the initial and repetitive inspections and any corrective actions set out in FAA AD 99‑18‑05 (Amdt 39‑11271) and the Boeing service bulletins referenced. The rule targets fatigue cracking in the vertical beam web and forward flange of the aft pressure bulkhead because such cracking can stop the beam from carrying fail‑safe loads and cause loss of cabin pressurisation; operators are responsible for inspections and repairs and must comply by 30 December 1999.
