The \"before further flight\" requirement means compliance is immediate and mandatory."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-28-45-gross-weight-reduction","history":"/api/acts/ad-pa-28-45-gross-weight-reduction/history","analysis":"/api/acts/ad-pa-28-45-gross-weight-reduction/analysis","conflicts":"/api/acts/ad-pa-28-45-gross-weight-reduction/conflicts","importantCases":"/api/acts/ad-pa-28-45-gross-weight-reduction/important-cases","documents":"/api/acts/ad-pa-28-45-gross-weight-reduction/documents"}}
