Plain English Summary

2/10 complexity

This CASA Airworthiness Directive mandates inspections for wear on the short torsion shaft spline in specified AlliedSignal (formerly Garrett/AiResearch) TPE331 turbine engines, using the manufacturer’s referenced service bulletin procedures.

It applies to owners/operators of those engine models and is safety-critical: unchecked wear can cause engine failure, and non‑compliance renders the aircraft unairworthy.
