Industries Commander 100 Series and Volair 10 Series—with serial numbers 026 and 037.\n\n**What it requires:** These aircraft must be modified **immediately** (the directive uses the term \"forthwith,\" meaning without delay) according to technical instructions contained in:\n*   Aero Commander Model 100 Service Letters 6, 10, 12, and 13\n*   Service Bulletin 1002\n\n**Why it matters:** This is a compulsory maintenance action. The directive itself doesn't detail the mechanical work; instead, it legally mandates compliance with the referenced manufacturer documents. Operating these aircraft without completing these modifications violates aviation law and renders the aircraft unairworthy."}},"importantCases":[],"_links":{"self":"/api/acts/ad-ac-100-2-general-modifications","history":"/api/acts/ad-ac-100-2-general-modifications/history","analysis":"/api/acts/ad-ac-100-2-general-modifications/analysis","conflicts":"/api/acts/ad-ac-100-2-general-modifications/conflicts","importantCases":"/api/acts/ad-ac-100-2-general-modifications/important-cases","documents":"/api/acts/ad-ac-100-2-general-modifications/documents"}}
