It was originally issued in December 1967 (noted as \"12/67\") and has since been replaced by a newer directive called **AD/AIRCON/1**.\n\n**Who it affects:** Owners and operators of Gulfstream G.159 aircraft (a twin-turboprop aircraft originally manufactured by Grumman).\n\n**Why it matters:** While this specific directive is no longer active, it forms part of the historical safety record for this aircraft type.
