It applies to all **Saab Safir 91B, 91B-2, 91C and 91D aircraft** — these are Swedish-made single-engine training and utility planes.\n\n**What it does:**\n- Requires owners and operators to **inspect, check, and retire (remove from service)** certain critical structural components and parts\n- These actions must follow the procedures in **Saab Service Bulletin 91.1.005 Revision 2** (a technical document from the manufacturer specifying when parts must be replaced due to age or wear)\n\n**Why it matters:**\n- **Safety-critical:** Aircraft parts have limited lifespans. Flying with aged or fatigued components risks structural failure.\n- **Mandatory compliance:** Airworthiness Directives are legally binding. You cannot fly the aircraft unless you comply.\n- **Effective date:** 30 May 1995 — this was the deadline for compliance.\n\n**Background:** This updates an earlier directive by referencing the latest manufacturer guidance, which replaced two older service bulletins (91.1.003 and 91.3.001). It also references a Swedish aviation safety document (LFV SAD 1-058 Revision B) — showing this adopts international standards from the aircraft's country of origin."}},"importantCases":[],"_links":{"self":"/api/acts/ad-saab-1-amdt-1-retirement-life-critical-components","history":"/api/acts/ad-saab-1-amdt-1-retirement-life-critical-components/history","analysis":"/api/acts/ad-saab-1-amdt-1-retirement-life-critical-components/analysis","conflicts":"/api/acts/ad-saab-1-amdt-1-retirement-life-critical-components/conflicts","importantCases":"/api/acts/ad-saab-1-amdt-1-retirement-life-critical-components/important-cases","documents":"/api/acts/ad-saab-1-amdt-1-retirement-life-critical-components/documents"}}
