Plain English Summary

3/10 complexity

The Civil Aviation Safety Authority requires operators of Pratt & Whitney JT9D-7F engines to carry out the inspections, repairs and other actions specified in FAA Airworthiness Directive 93-19-02 (effective 18 August 1994) to address reported diffuser-case rear‑rail cracking. Compliance—including inspection costs, repairs and downtime—falls to engine owners/operators; CASA incorporates the FAA AD by reference, so operators must consult it for the technical details.
