Plain English Summary

4/10 complexity

This Airworthiness Directive requires that certain Stage 1 and 2 turbine wheels for GE CT58 engines (listed in SB CT58‑72‑126 Rev.1) be installed in aircraft only after following the referenced installation procedure or AD/GE‑T/14A, with compliance required before installation at the next complete overhaul after 23 March 1970. It affects operators, overhaul/maintenance organisations and parts suppliers, creating a time‑triggered procedural obligation and shifting compliance costs and technical responsibility to those who overhaul and reinstall the wheels.
