Plain English Summary

3/10 complexity

This directive requires owners/operators of British Aerospace BAe 125 (HS/DH/BH up to Series 700) to carry out an eddy‑current inspection of main landing‑gear wheel flanges, following BA Service Bulletin 32‑201 and the mandated scan pattern/jig, completed by 31 August 1984. It’s designed to detect flange cracks after a reported fracture, shifts inspection and remediation costs to operators, and limits procedural discretion by mandating the manufacturer’s test method.
