Operators must follow the specific inspection and replacement procedures outlined in Bell Alert Service Bulletin 47-89-15 Rev A.\n\n**Who it affects:**\nThis applies to owners and operators of specific Bell 47 helicopter models: 47G2, 47G2A, 47G2A1, 47G3, 47G3B1, 47G3B2, 47G3B2A, 47G4, 47G4A, 47G5, 47G5A, 47J, 47J2, and 47J2A.\n\n**The deadline:**\nThe required action must be completed **before the aircraft flies again after 1 November 1989**.\n\n**Why it matters:**\nThe parts in question were manufactured without approval from Bell Helicopter or the FAA (Federal Aviation Administration). Unapproved parts may not meet safety standards and could fail in flight, posing a catastrophic risk to the aircraft and occupants."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-47-96-bogus-main-rotor-grip-p-n-47-120-252-11","history":"/api/acts/ad-bell-47-96-bogus-main-rotor-grip-p-n-47-120-252-11/history","analysis":"/api/acts/ad-bell-47-96-bogus-main-rotor-grip-p-n-47-120-252-11/analysis","conflicts":"/api/acts/ad-bell-47-96-bogus-main-rotor-grip-p-n-47-120-252-11/conflicts","importantCases":"/api/acts/ad-bell-47-96-bogus-main-rotor-grip-p-n-47-120-252-11/important-cases","documents":"/api/acts/ad-bell-47-96-bogus-main-rotor-grip-p-n-47-120-252-11/documents"}}
