Goodrich float bags** bearing specific serial numbers: R0694–R0746, R0748–R0847, and R0849–R0917.\n\n**What it requires:**\n- Follow the technical instructions in **Bell Service Bulletin 212-84-35** and **B.F. Goodrich Service Bulletin 84-31-056**\n- Complete these inspections before **December 31, 1984**\n\n**Why it matters:**\nB.F. Goodrich discovered that some float bags from these manufacturing batches were **made improperly** and had been returned for repair. Since these bags are emergency equipment designed to keep helicopters afloat during water landings, manufacturing defects could prevent them from inflating when needed. This directive ensures operators check the affected batches before the equipment fails in an actual emergency."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-212-31-float-bags-inspection","history":"/api/acts/ad-bell-212-31-float-bags-inspection/history","analysis":"/api/acts/ad-bell-212-31-float-bags-inspection/analysis","conflicts":"/api/acts/ad-bell-212-31-float-bags-inspection/conflicts","importantCases":"/api/acts/ad-bell-212-31-float-bags-inspection/important-cases","documents":"/api/acts/ad-bell-212-31-float-bags-inspection/documents"}}
