Plain English Summary

2/10 complexity

This directive requires that any Revmaster R2100D engine fitted with a cast (ductile steel) crankshaft be fitted with an equivalent forged crankshaft before the engine is installed in an aircraft. It affects engine owners, maintainers and installers, who bear the cost and must change procurement and pre‑installation checks. The AD replaces elements of a cancelled directive by focusing on mandatory replacement, while related inspection obligations are now covered separately.
