The technical instructions are contained in **Maule Service Letter No. 9**.\n\n**When:** **Forthwith** — meaning immediately or as soon as reasonably practicable. No grace period.\n\n**Why it matters:** Elevator trim control is critical for safe aircraft handling. This directive ensures these specific aircraft models meet safety standards for this component."}},"importantCases":[],"_links":{"self":"/api/acts/ad-ml-m4-3-elevator-trim-control-modification","history":"/api/acts/ad-ml-m4-3-elevator-trim-control-modification/history","analysis":"/api/acts/ad-ml-m4-3-elevator-trim-control-modification/analysis","conflicts":"/api/acts/ad-ml-m4-3-elevator-trim-control-modification/conflicts","importantCases":"/api/acts/ad-ml-m4-3-elevator-trim-control-modification/important-cases","documents":"/api/acts/ad-ml-m4-3-elevator-trim-control-modification/documents"}}
