AD/PHS/3 - Model 23260 and 43E-60 Low Pitch Stop Assembly - Inspection

This is a safety rule for aircraft propellers. 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.
