Does anyone know what happened to the FAA proposal for the icing AD for twin Cessnas?
FAA had issued a notice of proposed rule making ([Docket No. FAA–2011–0562; Directorate Identifier 2011–CE–015–AD]) and was trying to issue an AD to prevent twin Cessnas from flying in known icing conditions last June (2011). But I cannot find anywhere what became of it. Did it become a full AD?
