Engine — Exhaust System — Modification

EASA Airworthiness Directive 2017-0151R1 is a regulatory document addressing modification requirements for the exhaust system of GE Aviation Czech M601, H75, H80, and H85 series engines. These engines are commonly installed on aircraft such as Thrush Aircraft Inc. S-2R, PZL-106 Kruk, Air Tractor AT-300/400/500 series, Allied Ag Cat G-164 series, RUAG Do 28, and Aircraft Industries L-410. The directive mandates modifications to prevent potential power turbine or quill shaft spline failures that could lead to engine overspeed and subsequent safety hazards.
