Think of it as a formal notice telling aircraft owners they must fix or modify their planes to meet safety standards.\n\n**What it requires:** If you own or operate a Cessna 320F aircraft, you must fit an approved safety harness (or a combined lap belt and shoulder strap) to both the pilot's and co-pilot's seats.\n\n**Who it affects:** Owners and operators of all Cessna 320F model aeroplanes.\n\n**Why it matters:** This rule was made to protect pilots during accidents by ensuring they have proper upper-body restraint. The deadline to comply was 1 September 1971, so any Cessna 320F flying today should already have these harnesses installed."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-320-4-safety-harness-installation","history":"/api/acts/ad-cessna-320-4-safety-harness-installation/history","analysis":"/api/acts/ad-cessna-320-4-safety-harness-installation/analysis","conflicts":"/api/acts/ad-cessna-320-4-safety-harness-installation/conflicts","importantCases":"/api/acts/ad-cessna-320-4-safety-harness-installation/important-cases","documents":"/api/acts/ad-cessna-320-4-safety-harness-installation/documents"}}
