If you own, operate, or maintain **Hamilton Standard Model 23260 or 43E-60 propellers**, you must have a specific part—the **Low Pitch Stop Assembly**—inspected **before installing the propeller on any aircraft**. This assembly controls the minimum blade angle (pitch) of the propeller, and this check ensures it won't fail in flight. The inspection must be done following the technical procedures in **Hamilton Standard Service Bulletin No. 249** (or an older Airworthiness Notice). Essentially: check this specific safety-critical part before bolting the propeller onto the plane."}},"importantCases":[],"_links":{"self":"/api/acts/ad-phs-3-model-23260-and-43e-60-low-pitch-stop-assembly-inspection","history":"/api/acts/ad-phs-3-model-23260-and-43e-60-low-pitch-stop-assembly-inspection/history","analysis":"/api/acts/ad-phs-3-model-23260-and-43e-60-low-pitch-stop-assembly-inspection/analysis","conflicts":"/api/acts/ad-phs-3-model-23260-and-43e-60-low-pitch-stop-assembly-inspection/conflicts","importantCases":"/api/acts/ad-phs-3-model-23260-and-43e-60-low-pitch-stop-assembly-inspection/important-cases","documents":"/api/acts/ad-phs-3-model-23260-and-43e-60-low-pitch-stop-assembly-inspection/documents"}}
