The concern is a gap between the centre section of the wing and the outer wing panel that could allow a securing pin to rotate loose — potentially leading to wing failure.\n\n**Who it affects:**\nAnyone who owns or operates a Percival Proctor aircraft that hasn't already been modified according to \"Proctor Modification No. C1205\" (a factory-approved design change).\n\n**What must be done:**\n- **Inspect** the gap between the wing centre section and outer plane to ensure it's not large enough to let the top pin rotate and work loose\n- **If the gap is too large:** Either modify the aircraft using the approved modification (C1205), or use alternative compliance methods referenced as DCA/PROCTOR/7 or A.N.O. 105.1.26.2.6.2 (older regulatory references)\n\n**When:**\n\"Forthwith\" — meaning immediately, without delay.\n\n**Why it matters:**\nThis is a critical safety issue. If the pin withdraws partially, the wing structure could fail in flight. This directive ensures ageing aircraft (the Percival Proctor is a 1940s-era British military trainer and communications aircraft) remain airworthy."}},"importantCases":[],"_links":{"self":"/api/acts/ad-proctor-7-re-issue-wing-centre-section-inspection","history":"/api/acts/ad-proctor-7-re-issue-wing-centre-section-inspection/history","analysis":"/api/acts/ad-proctor-7-re-issue-wing-centre-section-inspection/analysis","conflicts":"/api/acts/ad-proctor-7-re-issue-wing-centre-section-inspection/conflicts","importantCases":"/api/acts/ad-proctor-7-re-issue-wing-centre-section-inspection/important-cases","documents":"/api/acts/ad-proctor-7-re-issue-wing-centre-section-inspection/documents"}}
