Industries Commander 100 Series and Volair 10 Series.\n\n**What the old rule required:** The original directive (from 1972) required owners to install **upper torso restraints** (shoulder harnesses/seatbelts) in these aircraft if they were built before 1967.\n\n**What this document does:** It scraps the old directive effective **28 August 2008**.\n\n**Why it matters:** The old requirement hasn't disappeared entirely—it's just been moved. A newer, broader directive (**AD/GENERAL/74 Amendment 1**) now covers shoulder harness requirements for these aircraft, making the old specific rule redundant. Aircraft owners and operators no longer need to follow AD/AC-100/11 specifically, but must still comply with the replacement general directive."}},"importantCases":[],"_links":{"self":"/api/acts/ad-ac-100-11-front-seat-restraint-installation-modification-cancelled","history":"/api/acts/ad-ac-100-11-front-seat-restraint-installation-modification-cancelled/history","analysis":"/api/acts/ad-ac-100-11-front-seat-restraint-installation-modification-cancelled/analysis","conflicts":"/api/acts/ad-ac-100-11-front-seat-restraint-installation-modification-cancelled/conflicts","importantCases":"/api/acts/ad-ac-100-11-front-seat-restraint-installation-modification-cancelled/important-cases","documents":"/api/acts/ad-ac-100-11-front-seat-restraint-installation-modification-cancelled/documents"}}
