If you haven't already done this work, you must complete it within **100 hours of flight time** after 31 March 1980.\n\n**Why it matters:** There was a risk that the holes in these hinge fittings could stretch out of shape (elongate) and the rudder spar could crack during normal use. Either defect could lead to loss of control of the aircraft during flight."}},"importantCases":[],"_links":{"self":"/api/acts/ad-rock-114-10-elevator-and-rudder-hinge-fittings-inspection-and-or-replacement","history":"/api/acts/ad-rock-114-10-elevator-and-rudder-hinge-fittings-inspection-and-or-replacement/history","analysis":"/api/acts/ad-rock-114-10-elevator-and-rudder-hinge-fittings-inspection-and-or-replacement/analysis","conflicts":"/api/acts/ad-rock-114-10-elevator-and-rudder-hinge-fittings-inspection-and-or-replacement/conflicts","importantCases":"/api/acts/ad-rock-114-10-elevator-and-rudder-hinge-fittings-inspection-and-or-replacement/important-cases","documents":"/api/acts/ad-rock-114-10-elevator-and-rudder-hinge-fittings-inspection-and-or-replacement/documents"}}
