Plain English Summary

3/10 complexity

This Airworthiness Directive requires operators of Boeing 727‑100, ‑100C and ‑200 aircraft (line numbers 1–1214) to perform inspections following the technical instructions of FAA AD 2000‑07‑12. Aircraft already modified by Boeing Service Bulletin 727‑57‑0127 Revision 2 or 3 are excluded. The directive names those SB modifications as terminating action for the recurring inspections. It matters because the inspections target fatigue cracking and corrosion; compliance work and modification costs fall to aircraft owners/operators, and CASA enforces the directive with an effective date of 15 June 2000.
