It requires owners and operators to replace the lower flying wire attachment lugs (part number 5-123-15) located at fuselage bulkhead No. 2 with stronger, reinforced versions. The replacement lugs must also be braced against drag loads in a way approved by the Secretary (the aviation safety regulator).\n\n**Who it affects:** Anyone who owns or operates a Ryan ST Series aeroplane.\n\n**What must be done:**\n- Remove the existing lower flying wire lugs at the specified location\n- Install reinforced lugs in their place\n- Ensure the lugs are braced against drag loads to regulatory standards\n\n**Deadline:** The work must be completed within 100 hours of flight time after 29 November 1974, unless already done.\n\n**Why it matters:** This prevents the flying wire attachments from failing, which could cause loss of aircraft control."}},"importantCases":[],"_links":{"self":"/api/acts/ad-ryan-1b-lower-flying-wire-lug-replacement","history":"/api/acts/ad-ryan-1b-lower-flying-wire-lug-replacement/history","analysis":"/api/acts/ad-ryan-1b-lower-flying-wire-lug-replacement/analysis","conflicts":"/api/acts/ad-ryan-1b-lower-flying-wire-lug-replacement/conflicts","importantCases":"/api/acts/ad-ryan-1b-lower-flying-wire-lug-replacement/important-cases","documents":"/api/acts/ad-ryan-1b-lower-flying-wire-lug-replacement/documents"}}
