This directive addresses a specific safety issue identified by Boeing in Service Bulletin No. 32-93. The word \"Forthwith\" means **immediate compliance is required** — there's no grace period because the risk is serious enough to demand urgent action.\n\n**Key details:**\n- **Document reference:** Boeing Service Bulletin 32-93 (this tells mechanics exactly what to inspect and how)\n- **Compliance deadline:** Forthwith (immediately — before the next flight)\n- **Date issued:** 7/66 (July 1966 — this is a very old directive, reflecting the 727's era)"}},"importantCases":[],"_links":{"self":"/api/acts/ad-b727-30-nose-landing-gear-actuating-rod-inspection-and-replacement","history":"/api/acts/ad-b727-30-nose-landing-gear-actuating-rod-inspection-and-replacement/history","analysis":"/api/acts/ad-b727-30-nose-landing-gear-actuating-rod-inspection-and-replacement/analysis","conflicts":"/api/acts/ad-b727-30-nose-landing-gear-actuating-rod-inspection-and-replacement/conflicts","importantCases":"/api/acts/ad-b727-30-nose-landing-gear-actuating-rod-inspection-and-replacement/important-cases","documents":"/api/acts/ad-b727-30-nose-landing-gear-actuating-rod-inspection-and-replacement/documents"}}
