Initial inspection is within 25 flight hours, with repeats every 300 hours. The checks address loose pins or sloppy fittings that could cause trim‑tab failure and possible loss of control."}},"importantCases":[],"_links":{"self":"/api/acts/ad-swsa226-6-trim-tab-actuator-rods-inspection","history":"/api/acts/ad-swsa226-6-trim-tab-actuator-rods-inspection/history","analysis":"/api/acts/ad-swsa226-6-trim-tab-actuator-rods-inspection/analysis","conflicts":"/api/acts/ad-swsa226-6-trim-tab-actuator-rods-inspection/conflicts","importantCases":"/api/acts/ad-swsa226-6-trim-tab-actuator-rods-inspection/important-cases","documents":"/api/acts/ad-swsa226-6-trim-tab-actuator-rods-inspection/documents"}}
